I'm in a small town with no bike shop around. I need to get my electric bike fixed before my first day at work tomorrow otherwise i'll be sweaty all day. After watching the video through I found the easy fix was the last tip at the end of this video! ha Saved my day! Thank you
Best Video for troubleshooting E-bikes. I just got mine 3 days ago and tonight was the first time where I had to fold it up and transport it. After taking it out the bike wasn't working. I tried everything from checking the wires multiple times to checking the fuses, the battery...etc. I was running out of options and frustrated. After watching this video, I made it to the 3:41 second mark until I realized it was the brake! Super helpful! Thank you!
Well done sams bike shop, my ebike wouldn't power up,i watched cort and sam on RUclips and learned my bike had trouble with the battery not connecting with my controller.as my ebike is a folding bike I think there is a problem with the open close folding of the bike this could be a problem with folding bikes, don't fold up your bike too much.I'm from England and I learn a lot from sam and cort.
*Excellent, very informative!* The video features a discussion at Myron's Xtreme Machines in Fullerton, California, focusing on troubleshooting electric bicycles. Here’s a summary of the main points covered: 1. Battery Check: The first step in troubleshooting is to verify that the battery has enough voltage. A voltmeter can be used to check the voltage directly from the battery or via connectors. A fully charged 48-volt battery should read around 52 volts. 2. Connections: Loose or bent prongs in the battery connectors can prevent power from reaching the bike. It's important to check these connections for proper contact. 3. Brake Inhibitors: If the bike powers on but doesn't function, the brake inhibitors may be causing a cutoff. Inspecting the brake levers and ensuring they are not bent or misaligned can resolve this issue. 4. Wiring Issues: Tracing wires to check for disconnections or damage is essential. Problems with the throttle, pedal assist, or cadence sensors can also prevent the bike from functioning properly. 5. Torque Sensors: Advanced bikes might have torque sensors that can malfunction, leading to issues with pedal assist. If adjustments don’t work, these may need to be replaced. 6. Maintenance Tips: Regular maintenance is crucial to avoid problems, such as ensuring all parts are tight and properly assembled. This includes checking the bottom bracket and keeping wiring clear of pinch points. 7. Professional Help: If troubleshooting at home doesn’t resolve the issue, seeking help from a local electric bike shop is recommended, especially if the bike is complex. 8. Safety: Wearing a helmet while riding is emphasized as a critical safety measure. Overall, the video provides practical advice for diagnosing common electric bike issues and highlights the importance of regular maintenance and safety precautions.
This video saved a trip to the repair shop for me. I have a five year old Genze. The company folded up almost 2 years ago. What to do? I recently had the original battery rebuilt. Had power to the LCD, but bicycle no go. After watching this video, I checked the motor shut off, which looked a lot like the one pictured, under the hand brake. Lo and behold it had come a bit loose and was shifted sideways maybe a quarter of an inch. I put it back where it belonged, tightened the screw and voila! I'm back in business. Thanks much!
Great video, I swear that is so detailed and so easy to follow I have had an e-bike two weeks and learned so much in one sitting. I'm excited to have a working bike soon
This is a great guy for the ebike business! I'm here in Michigan, so unfortunately, I can only see you work with him in your videos, but let him know, that he is appreciated here in Michigan!
Honestly I miss these videos. Sam is one hell of a character. Cheerful, and had a talent for making relatively complex mechanics/concepts sound effortless. In other videos, hearing how he goes the extra mile when service, if I was anywhere close to the region, I would stop by. C, bring these videos back man. Keep up the great work!
This video helped me repair my new ebike. The manufacturer's documentation failed to help out but this video told me where to start looking/troubleshooting. Within 15 minutes I had my bike up and running for the first time.
First time I've seen an electric bike lift. Love this vid, Court. It's like a basic primer for new e-bike owners when the durn blasted bike won't turn on...
This is just superb, I been tryin to find out about "proper bicycle maintenance" for a while now, and I think this has helped. Ever heard of - Viyackson Yenacob Review - (do a google search ) ? Ive heard some incredible things about it and my mate got great success with it.
Very great! The fact that my local bike shop might be not able to fix e-bikes was definitely one concern so far but I think sometimes you might be even able to fix it yourself! Good video!
Yes. Most bike shops in my area dont even want to touch my e-bike. I live 2½ hours from NYC and that's the nearest e-bike shop. So I just bought a new bike. I'm gonna look it over after this video and see if it's a simple wiring. Thanks for tips
You probably won't read this comment. But I can't thank you enough for this video. I have an ebike kit that hasn't work for a while. I have been trying different methods, spending lots of money to try and sort it out, brought the wrong wire connectors etc. I got to a point where I almost gave up. But when you mentioned the brake lever being ever so slightly pulled, I check mine and where you put the cable, that was stopping it from being fully closed. I can't believe after all that money and that was the bloody issue.
Thank God there's ebike shop's on RUclips to help people like me to troubleshoot certain things cause I don't have any place we're I live that can help me thank you for the info. 👍
Fantastic video, I just fixed my pulsing almost no current ebike, magnets were dirty and the disc they were on was out of place and on an angle, would have never thought of that before watching your video, thanks heaps.
Helpful video. In out community bicycle shop in Benton Harbor, Mi we have little experience with e-bikes and are trying to learn more. Several of our volunteers ride them and even they are learning. One safety thing - we do not allow anyone to wear flip flops or open toe shoes in our shop. just not safe!
This video saved me hours of time and helped me learn more about how ebike works and troubleshooting . You explained it very well. great job. Thanks again.
thank you. You helped fix my problem. o9ne of the inhibitors on my handle bar was making it so the engine would start. ran down the wire found it discounted it and I am good to go. still wish I knew why it didn't work. e-bike shops around where I live are pretty far away but I will have to get to one to find out why It doesn't work some day. going to go have fun with my new bike thanks once again.
Thank you, Thank You Thank YOU, I just crashed my Sondor's today and bent the front fork forcing the front wheel into the frame. The front tire was pushed so far back I couldn't steer at all. I was able to turn the handle bar around in reverse and steer but I had to disconnect the front brake at the handle bars to make a 190 degree turn of the handle bars. By doing so I didn't realize until I watch this video that I cause the Brake lever to disconnect the Brake Inhibitor Switch and there for caused the motor not to work. It did work for about 100 feet but then stopped. Because I bent the forks the tire was rubbing and causing what felt like breaking, which I thought I might have damaged the motor because of over heating. That wasn't the case, once I fixed the Brake Lever everything works fine. Everything except the front Fork, it will need to be replaced. Thank you for making these very informative video's.
It’s surprising that the experienced e-bike shop is not describing one common electrical problem, the LCD display connected to the power button pad got bad. Which problem can be nailed down by simply plugging the battery and see whether they can be charged regardless of the e- bike not powering up. If the battery is charging then the faulty is the display which can be easy replaced and the new kit of display cabled to the power switch on/off will be connected instead.
This answered my question, I ordered an ebike kit and the brake sensor has levers I can’t use because my Shimano brakes are intergraded into the shifters. Also the PAS needs to be installed by taking off the pedal. I’m going to leave the PAS and the Brake Assist off. Just not connect them.
I think you solved my problem. Now, I just need to test the theory. I noticed my brake light kept coming on or staying on after use. At the same time my motor which is on both wheels keeps stopping, It feels very intermittent. Does anyone know what colour the break inhibitor connection is on a modern bike or if there is a colour code? Thanks for a great video that's 9 years old!
Thanks guys. Glad to see this kind of advocacy. I can't ride a bicycle, but I have 3 mobility scooters, including a boomerbeast 2 offroad, which is using ebike components and drives all 3 wheels.
my pedal assist stopped working i live in a very poor area of a very rich country and none of the 5 bike shops within riding distance will work on e-bikes, I was certain the magnets sensor was the problem I noticed it can freewheel but still it must go past the sensor , but I didn't know were the sensor is now I'm confident I can fix it or be closer to the problem, funny enough I also thought if it wasn't that its the connections you spoke about
thanks it was the brake inhibitor that was killing my bike from going. I pulled off the wires to both brakes and that was it. Now i have to figure out what will fix it from killer the power and working right again?
I hope you check your comments for questions because I have a question about my battery prongs, it shorted out and burnt up a prong on my e bike/controller connection. You started to explain a little on that connection. My question is, where can I find a replacement connection for where my battery and controller meet?
Thank you very much for this video. The prongs weren't lining up right on mine. I went to a bike shop and they told me I needed a new battery and tried to charge me $580 for it. I cussed them out and "threw franks" all over the place. I seen this video and came up with an idea, I put some aluminum that I got off a take out food plate and surrounded the prongs with it to complete the charge. Now the bike works like new, and I got it off of Facebook marketplace for $150 because the original owner didn't know how to diagnose the problem lol. Now I got a great ebike for $150. I feel like going back to the bike shop, showing them how I fixed it without purchasing a new battery, and cuss them out some more, but I will leave it alone and be happy that I got a bike that was dirt cheap to work.
loved you knowledge and presentation, i can't find any information on why my display on my Juiced bike turn on then turn screen turns blue make it unreadable..only had bile 3 days..bad display? only had bike 3 days
A simple error by a bike shop which turned out to be a disaster for me: Cyrusher XF-900 Rear Hub Motor; they placed the 'tab washer' on the wrong side of the dropout (disc brake rotor side) and the rear wheel eventually came off when I attempted to move. If this happened when I was already moving the outcome could have been disastrous. Both tab washers need to be on the inside of the dropout with the tabs both pointing away from the bike.
I have a Jenson pro I have a drill battery 40 volt and it's been working good..and the other day I accidentally hooked it in backwards and it sparked at the battery end and it stopped working but the control module didn't smell or looked burnt and I tried a different battery and no power still did I fry the control module and if so we're can I get a used one cas I don't have very much money my friend gave this to me for transportation for a job..Thanx
Great video. Very informative. Thanks guys. My bike is rather new and the motor makes a struggling noise and stops in assist mode. Comes back again after a minute or so. Any clues what may be wrong. Any advice will be appreciated. Thanks
Hi, I just wired my ebike kit, following the manufacturers instructions, and as soon as you turn the throttle key on, it reads 51V and the wheel starts spinning at full speed. Crank the throttle and it comes to a stop and reverses at full speed, not good! Any clues?
My new Lectric XP foldable bike's hand-throttle stopped working on the second day. I informed the company but have yet to hear back from them. I can get by with pedal assist, but .. . .
@@seminolerick6845 I still have the problem, that said, Lectric has stepped up and been as supportive as they can from 2000 miles away. They called me at home said they will cover all costs.
i received a new battery which was too big and the bike shop had to move the thing the battery plugs into and now when i switch it on the lcd will light up and go off but generally if i switch the battery off and on again it will light up and its powered up sometimes i have to do this multiple times before it powers up. Do you guys know what the problem is? Watching you video could it be the prongs arent lining up right? Any advice will be very much appreciated...
Heya very helpful I have a ancheer got it as a present it has developed a fault it has pedal assist it works fine in low mode but mid and high work for 2 secs then the bike turns off then you have to toggle battery off and in again and also does this on twist and go throttle
Can you leave an e bike plugged in and charging after it is charged? We had 2 Jamis e bikes with the Hyena e system and the assist kept shutting off. They replaced the controller where the battery slides in and the crank sensor and both still had problems with the assist. Also both chargers quit during the first year.Maybe since we left them plugged it all the time it was frying something (the dealer we bought them from told us it was okay to leave them plugged in all the time)
Hi Thanks! Great vid! I have some problems with the e-bike that it doesn not switch on at all. I checked the battery and two of them as I have., It is the same problem with both of the batteries. It is all switched off. The controller can not start it up. The battery from the pins are not leaving any voltage (both of them). My Q is there a fuse inside like always or not? I have a power check with diods this is having full power and I can also charge it with no problem. I changed to different controllers they are all used but some would work., Inside that controller is a battery. Can that give me problems starting up like it would be like on/off pushbutton function?
Am totally new to this, so this may sound dumb... Is there a ‘flowchart’ type guide somewhere on basic troubleshooting... what to check/ look for ? A laminated such item would be great on the trail !
Thank you so much, you’ve helped me diagnose and resolve my problem with the pedal assist not working. I’m from New Zealand and am usually hopeless at fixing technical things, so I really appreciate this video!
Trying to fix husband’s bike. Error 3003. They company, iwheel, slipped a ‘not covered under warranty’ into the manual for if you buy from Amazon or Walmart(never said before then- we got it walmart) and we can’t get it fixed otherwise. Trying to fix it myself but I don’t even know where to look.
Can you give me your impression of a fault in my lombardo modeno 250. There is no battery problem. The bike starts off strong when suddenly the motor power just STOPS and the display goes dead. The STOP first occurred in POWER LEVEL THREE. A few minutes later the same would happen in POWER LEVEL TWO, Less than a minute later it would die in POWER LEVEL ONE. The entire bike was dead. I can hit the power button and it would light up and would begin to run but would stop in TEN SECONDS. I can hit the power button and it would run for about ten feet then die. I could do that all day. Does that sound like something that indicates a particular problem that can be rep
I noticed I'll try not to. I've written it in the wet a lot recently when I took apart the controller, safety box or whatever you want to call it and check my wiring. I went to the solder one of the wires that wasn't a straight connection is like the connection piece on the end of each wire. One for the battery went from the controller so I had to solder that together because the tips were so corroded I didn't think I could even clean it once I did try to clean it, it just started bending it back connectors. So much that they wouldn't fit back together very well either way. But when I tried to find a clean chunk of the wire to solder tools, I followed it on my back to the controller itself and the wire looked, chard what burned all the way 4-6 inches and I wound up having two soldiers. Basically about 2 inches from the controller unit itself could that have caused my battery to fail Or maybe the bms got tripped
Great video. Very informative. I have a pedal assist ebike and sometimes the motor stops and only starts again after a couple of minutes (the battery is charged. The display stays on, just the motor stops ). It's been happening more frequently recently.. It's a new ebike. Any thoughts? Thanks a lot 👍
Check your keypad and battery connector loose wire to battery , pulled out from folding check all connectors I have 2 Vivi electric bike where cable connector came disconnected . spray w d 40 and check voltage flow unplug connectors and realign cable where no kinks
I have a small electric bike that is brand new that will not turn on unless it is hooked up to the charger. When I have it plugged in it will turn on and it shows a full battery and horn honks but no throttle. When unplugged nothing will turn on. Totally dead. Any advice??
I wish you were in my city all my shops refuse to work on bikes not bought from them so I’m stuck with my broken e bike I got to use a week tried to do wire management and now it won’t turn on spent like 10 hours trying to get it to work
Hi, Some of the rear wheel motor cable wires on my A2B Alva+ 2013 24-inch tire broke off from the connector. I am looking for a diagram of the connector so I can solder the wires back. I will appreciate it very much. Question: Someone game a diagram the diagram they gave has a green wire my connector has a white wire no green, should i solder my white wire to the location the green wire goes?
The problem my bike shop said is that my Shimano crank is tapered and the PAS takes up room so that my crank will not slide back on all the way, I can tighten the bolt but the crank is not seated all the way and the bike shop said it will eventually wear out the crank arm since it is not tightly seated. Is there a PAS system that will work in this case?
I have an ask Hunter E bike the battery is fully charged, but when I power it up I only show one bar and the battery display. Checked all the cables seem to be good The light and the horn work fine but cannot get the bike to operate. if you could please have any suggestions I would appreciate it. Thanks
Bro , i have 48v 500w ebike , After a rainy day my ebike speed cut off on its own , throttle sometimes dont work but today i just turn on the key and after some seconds my bike speeds up on its own crushing with wall , i was lucky that this happen inside my garden and not in street trafic . Can you explain its throttle problem or motor ??
What do you do if your ebike gets stuck at a particular power level? Mine goes 1-5 but seems stuck at level 4 even though the display adjusts visually as it should.
What could be the reason if the speedo and odo stop working or work intermittently everytime after the bike has done 2 km ? I replaced the LCD monitor and the controller, but it is still the same. Thanks !
Hello Sam! I ve have a problem ? Maybe you can help me, my bike have a front hub 8Fun motor and have been running in 11 year`s now with no problem. But now I can ride about 300 meter`s and then the Power disappeaar? I can cut off the battery (36volt) and then It start`s up again, and do the same, Problem I am living in Denmark, and have asked the mechanic`s in my hometown-They just say they dont Know.... Looking forward to get a respond from you....Have a good day....
so so helpful..i live in brooklyn NY and have two bme electric bikes that i ordered online from Northridge CA..i have two new 36v 9a kettle tube type batterys on the bikes that failed within six months and with just about 60 charges total..cant seem to figure out how to get my expensive ebikes to run..this info may b helpful..thanks much..
So I have an issue with my motor when I let off the speed control. The motor has drag when I am rolling down hill if I am on level ground it's slows down. The first 50 miles was good but I am at 100miles now. Any thoughts
Just wondering how much would it be to fix anything like faulty pedal sensor or something like that because that's what I'm having on my eBay right now. The pedal assist is not working and it's a Jason e-bike
back in the day i used to install electric fans for a hardware store i charge $75 do it in 2 hr,with assembly ,but every year it was different and had to read the manual ,so what (you) do to keep up with assembly ? & different stuff
I was wondering if you could give me some insight into the problem with my bike. I have an electric bike that shuts off after a few seconds of riding. In both cases, using the pedal accelerator or the throttle control button, it happens. The bike display indicates the battery is full and there are no issues.
I have an old ebike. A few months ago, "almost a year" i rided it casually in a bumby road and the throttle just stopped working. I opened the control box thingy and red and yellow wires that were coming from the throttle cable were damaged. Red wire was cut and yellow were damaged alot. Please help the place where the controlbox is its too small to operate anything. Please help if you can cause i want to enjoy this summer. 🥲😪
Hey man keep up the good videos. Can anyone point me in the right direction, I've got a mid drive motor on my bike. Everything works, I lift my back wheel up and it spins perfectly, but when I sit on the bike the motor just shudders and doesn't have the strength to drive forward. Any ideas??? Does it sound like it's the clutch?? Thanks
Why not build your own and learn. If you have bike now,your half way there. Get a kit to fit and build your own ebike.Check out Bafang mid drive.That way you learn how to fix your own ebike.
Like you said some useful stuff but I came here looking at how to fix a problem not troubleshoot poor design issues.... Had my bike for a few days and I made changes to a few things like placing a dam spring behind the magnet plate.... But when it comes to the engine itself you didn't give me any info that was helpful... My bike is make extra noise when I ask her to give some force... It's kinda grinding/whiting noise I cannot place... I felt like it was the gears but they seem fine.... Re-greased the gears and inspected the mint coils.! Placed back together carefully and she still makes this noise...
Hello, can you tell me what error code 36 means? The bike makes a weird noise from the motor then it cuts on and off repeatedly. I’m lost. This is a new bike with only 45 miles on it. The mileage was put on over the past month. Please help 😬
I purchased a new Aventon Level E Bike in Mar 2022, it has the cheap zoom fork, after about 2 weeks the front fork makes a clunk sound when going over some bumps and it's pissing me off, it does not do this when it's locked out though, does anyone know what the issue is? Or even an upgrade fork the would fit this bike? Thanks John
Do you use the ebike electrical testers, e.g. Romia to troubleshoot problems? Is there a wire harnesses that adapts the testers connector to the ebike controller cable and also to the wheel motor (pony) cable?
I'm in a small town with no bike shop around. I need to get my electric bike fixed before my first day at work tomorrow otherwise i'll be sweaty all day. After watching the video through I found the easy fix was the last tip at the end of this video! ha Saved my day! Thank you

Hi Check battery connector that solder wire diffused to battery
Well done sams bike shop, my ebike wouldn't power up,i watched cort and sam on RUclips and learned my bike had trouble with the battery not connecting with my controller.as my ebike is a folding bike I think there is a problem with the open close folding of the bike this could be a problem with folding bikes, don't fold up your bike too much.I'm from England and I learn a lot from sam and cort.

Thanks for a great video that's 9 years old!
Thanks so many basic but important checks. After watching i fixed the problem I've had for months. Thanks!
Thanks guys. Glad to see this kind of advocacy. I can't ride a bicycle, but I have 3 mobility scooters, including a boomerbeast 2 offroad, which is using ebike components and drives all 3 wheels.
6 years later and it just saved me allot of time and money.
Thank you very much for the video. It’s super practical and useful!!!
Sure thing! I'm glad that you enjoyed it, thanks for the positive comment :D
my pedal assist stopped working i live in a very poor area of a very rich country and none of the 5 bike shops within riding distance will work on e-bikes, I was certain the magnets sensor was the problem I noticed it can freewheel but still it must go past the sensor , but I didn't know were the sensor is now I'm confident I can fix it or be closer to the problem, funny enough I also thought if it wasn't that its the connections you spoke about
thanks it was the brake inhibitor that was killing my bike from going. I pulled off the wires to both brakes and that was it. Now i have to figure out what will fix it from killer the power and working right again?
I hope you check your comments for questions because I have a question about my battery prongs, it shorted out and burnt up a prong on my e bike/controller connection. You started to explain a little on that connection. My question is, where can I find a replacement connection for where my battery and controller meet?
It maters so much when a bike shop works with , and values there customers . Like Edinburgh bike coop did for me . With my ebco E bike .
Thank you very much for this video. The prongs weren't lining up right on mine. I went to a bike shop and they told me I needed a new battery and tried to charge me $580 for it. I cussed them out and "threw franks" all over the place. I seen this video and came up with an idea, I put some aluminum that I got off a take out food plate and surrounded the prongs with it to complete the charge. Now the bike works like new, and I got it off of Facebook marketplace for $150 because the original owner didn't know how to diagnose the problem lol. Now I got a great ebike for $150. I feel like going back to the bike shop, showing them how I fixed it without purchasing a new battery, and cuss them out some more, but I will leave it alone and be happy that I got a bike that was dirt cheap to work.
Thanks for the info, I managed to get my 14 year old neighbours bike going for the first time in a year, great info..
Sam's a nice guy. Visited him in person from watching your videos.
This just helped me with an escooter fix. Thanks for posting clear and knowledgeable videos.
loved you knowledge and presentation, i can't find any information on why my display on my Juiced bike turn on then turn screen turns blue make it unreadable..only had bile 3 days..bad display? only had bike 3 days
A simple error by a bike shop which turned out to be a disaster for me: Cyrusher XF-900 Rear Hub Motor;
they placed the 'tab washer' on the wrong side of the dropout (disc brake rotor side) and the rear wheel eventually came off when I attempted to move. If this happened when I was already moving the outcome could have been disastrous.
Both tab washers need to be on the inside of the dropout with the tabs both pointing away from the bike.
I have a Jenson pro I have a drill battery 40 volt and it's been working good..and the other day I accidentally hooked it in backwards and it sparked at the battery end and it stopped working but the control module didn't smell or looked burnt and I tried a different battery and no power still did I fry the control module and if so we're can I get a used one cas I don't have very much money my friend gave this to me for transportation for a job..Thanx
Great video. Very informative. Thanks guys.
My bike is rather new and the motor makes a struggling noise and stops in assist mode. Comes back again after a minute or so.
Any clues what may be wrong.
Any advice will be appreciated. Thanks
Dead battery cells
Hi, I just wired my ebike kit, following the manufacturers instructions, and as soon as you turn the throttle key on, it reads 51V and the wheel starts spinning at full speed. Crank the throttle and it comes to a stop and reverses at full speed, not good! Any clues?
I just got my bike,everything is lighting up but the motor isnt working.the number 3 is just flashing
My new Lectric XP foldable bike's hand-throttle stopped working on the second day. I informed the company but have yet to hear back from them. I can get by with pedal assist, but .. . .
Steve Smith utt ohh...just ordered one 7/10/19 🥴
@@seminolerick6845 I still have the problem, that said, Lectric has stepped up and been as supportive as they can from 2000 miles away. They called me at home said they will cover all costs.
Steve Smith hope they do... good luck !
i received a new battery which was too big and the bike shop had to move the thing the battery plugs into and now when i switch it on the lcd will light up and go off but generally if i switch the battery off and on again it will light up and its powered up sometimes i have to do this multiple times before it powers up. Do you guys know what the problem is? Watching you video could it be the prongs arent lining up right? Any advice will be very much appreciated...
Good video..I fell off my bike and after the wires for the headlights broke after I repaired the wires the headlights and taillights won't turn off
Heya very helpful I have a ancheer got it as a present it has developed a fault it has pedal assist it works fine in low mode but mid and high work for 2 secs then the bike turns off then you have to toggle battery off and in again and also does this on twist and go throttle
My pas 1 to 5 works when I’m not on the bike when I get on it I change from pas 1 to 5 but get no power there ?
What type of tools should you carry with you to do wuick fixes on a ride
I have a Gotrax EBE 2
When I pedal it goes but not to fast
Throttle is not working
On the display E 08 code
Can you able to help me out please
Can you leave an e bike plugged in and charging after it is charged? We had 2 Jamis e bikes with the Hyena e system and the assist kept shutting off. They replaced the controller where the battery slides in and the crank sensor and both still had problems with the assist. Also both chargers quit during the first year.Maybe since we left them plugged it all the time it was frying something (the dealer we bought them from told us it was okay to leave them plugged in all the time)
Hi Thanks! Great vid! I have some problems with the e-bike that it doesn not switch on at all. I checked the battery and two of them as I have., It is the same problem with both of the batteries. It is all switched off. The controller can not start it up. The battery from the pins are not leaving any voltage (both of them). My Q is there a fuse inside like always or not? I have a power check with diods this is having full power and I can also charge it with no problem. I changed to different controllers they are all used but some would work., Inside that controller is a battery. Can that give me problems starting up like it would be like on/off pushbutton function?
Am totally new to this, so this may sound dumb... Is there a ‘flowchart’ type guide somewhere on basic troubleshooting... what to check/ look for ? A laminated such item would be great on the trail !
Thank you so much, you’ve helped me diagnose and resolve my problem with the pedal assist not working. I’m from New Zealand and am usually hopeless at fixing technical things, so I really appreciate this video!
Should I put a external inline fuse on my e-bike battery??
Trying to fix husband’s bike. Error 3003. They company, iwheel, slipped a ‘not covered under warranty’ into the manual for if you buy from Amazon or Walmart(never said before then- we got it walmart) and we can’t get it fixed otherwise. Trying to fix it myself but I don’t even know where to look.
Let the man talk......the Bike Shop man...!!
My throttle has black purple and white wire where do they connect to in the controller
Great job
Can you give me your impression of a fault in my lombardo modeno 250.
There is no battery problem.
The bike starts off strong when suddenly the motor power just STOPS and the display goes dead.
The STOP first occurred in POWER LEVEL THREE.
A few minutes later the same would happen in POWER LEVEL TWO,
Less than a minute later it would die in POWER LEVEL ONE.
The entire bike was dead.
I can hit the power button and it would light up and would begin to run but would stop in TEN SECONDS.
I can hit the power button and it would run for about ten feet then die.
I could do that all day.
Does that sound like something that indicates a particular problem that can be rep
I noticed I'll try not to. I've written it in the wet a lot recently when I took apart the controller, safety box or whatever you want to call it and check my wiring. I went to the solder one of the wires that wasn't a straight connection is like the connection piece on the end of each wire. One for the battery went from the controller so I had to solder that together because the tips were so corroded I didn't think I could even clean it once I did try to clean it, it just started bending it back connectors. So much that they wouldn't fit back together very well either way. But when I tried to find a clean chunk of the wire to solder tools, I followed it on my back to the controller itself and the wire looked, chard what burned all the way 4-6 inches and I wound up having two soldiers. Basically about 2 inches from the controller unit itself could that have caused my battery to fail Or maybe the bms got tripped
thank you so much. Following you tutorial, I think I fixed the problem.
Thanks man this has really really saved me today. If not I would have pay for motel
Great video. Very informative. I have a pedal assist ebike and sometimes the motor stops and only starts again after a couple of minutes (the battery is charged. The display stays on, just the motor stops ). It's been happening more frequently recently.. It's a new ebike. Any thoughts? Thanks a lot 👍
Have the same problem with my used Jetson gen 1 bike. Still haven’t figured it out.
Check your keypad and battery connector loose wire to battery , pulled out from folding check all connectors I have 2 Vivi electric bike where cable connector came disconnected . spray w d 40 and check voltage flow
unplug connectors and realign cable where no kinks
@@susankober6169 thank you. I've already got the bike replaced. The problem got worse and even the shop couldn't fix it lol.
I have a small electric bike that is brand new that will not turn on unless it is hooked up to the charger. When I have it plugged in it will turn on and it shows a full battery and horn honks but no throttle. When unplugged nothing will turn on. Totally dead. Any advice??
I watched this video multiple times. Golden.
I wish you were in my city all my shops refuse to work on bikes not bought from them so I’m stuck with my broken e bike I got to use a week tried to do wire management and now it won’t turn on spent like 10 hours trying to get it to work
I have a sukara fold up ebike it runs great wen I'm not sat on it. . But wen I sit on it twist throttle and all power goes off. . Any ideas?
got the same thing happening on my folding ebike - did you manage to figure out what the issue was, and what was the solution?
I own a surface 604 shred and I am on my 2nd torque sensor, Feels very jerky....My throttle works fine.. any suggestion?
Hi, Some of the rear wheel motor cable wires on my A2B Alva+ 2013 24-inch tire broke off from the connector. I am looking for a diagram of the connector so I can solder the wires back. I will appreciate it very much. Question: Someone game a diagram the diagram they gave has a green wire my connector has a white wire no green, should i solder my white wire to the location the green wire goes?
The problem my bike shop said is that my Shimano crank is tapered and the PAS takes up room so that my crank will not slide back on all the way, I can tighten the bolt but the crank is not seated all the way and the bike shop said it will eventually wear out the crank arm since it is not tightly seated. Is there a PAS system that will work in this case?
I have an ask Hunter E bike the battery is fully charged, but when I power it up I only show one bar and the battery display. Checked all the cables seem to be good The light and the horn work fine but cannot get the bike to operate. if you could please have any suggestions I would appreciate it. Thanks
So what is the avg hourly labor charge for working on a eBike at a BikeShop? (2024)
Bro , i have 48v 500w ebike , After a rainy day my ebike speed cut off on its own , throttle sometimes dont work but today i just turn on the key and after some seconds my bike speeds up on its own crushing with wall , i was lucky that this happen inside my garden and not in street trafic . Can you explain its throttle problem or motor ??
What do you do if your ebike gets stuck at a particular power level? Mine goes 1-5 but seems stuck at level 4 even though the display adjusts visually as it should.
What could be the reason if the speedo and odo stop working or work intermittently everytime after the bike has done 2 km ? I replaced the LCD monitor and the controller, but it is still the same. Thanks !
Love the common sense approach,thx for the great information.
Hello Sam! I ve have a problem ? Maybe you can help me, my bike have a front hub 8Fun motor and have been running in 11 year`s now with no problem. But now I can ride about 300 meter`s and then the Power
disappeaar? I can cut off the battery (36volt) and then It start`s up again, and do the same, Problem
I am living in Denmark, and have asked the mechanic`s in my hometown-They just say they dont Know....
Looking forward to get a respond from you....Have a good day....
so so helpful..i live in brooklyn NY and have two bme electric bikes that i ordered online from Northridge CA..i have two new 36v 9a kettle tube type batterys on the bikes that failed within six months and with just about 60 charges total..cant seem to figure out how to get my expensive ebikes to run..this info may b helpful..thanks much..
need larger batteries, those are draining tooo fast and wearing out. 1-18a is WAYbetter than 2 x 9a
So I have an issue with my motor when I let off the speed control. The motor has drag when I am rolling down hill if I am on level ground it's slows down. The first 50 miles was good but I am at 100miles now. Any thoughts
Does the ebike tire have to match the controller and lcd if it has the same terminals....
Great hints
Just wondering how much would it be to fix anything like faulty pedal sensor or something like that because that's what I'm having on my eBay right now. The pedal assist is not working and it's a Jason e-bike
Great video I have an e bike made by G Plus. Would you look at it?
back in the day i used to install electric fans for a hardware store i charge $75 do it in 2 hr,with assembly ,but every year it was different and had to read the manual ,so what (you) do to keep up with assembly ? & different stuff
I was wondering if you could give me some insight into the problem with my bike. I have an electric bike that shuts off after a few seconds of riding. In both cases, using the pedal accelerator or the throttle control button, it happens. The bike display indicates the battery is full and there are no issues.
I’m having the same exact issue and can’t find any info
I have an old ebike. A few months ago, "almost a year" i rided it casually in a bumby road and the throttle just stopped working. I opened the control box thingy and red and yellow wires that were coming from the throttle cable were damaged. Red wire was cut and yellow were damaged alot. Please help the place where the controlbox is its too small to operate anything. Please help if you can cause i want to enjoy this summer. 🥲😪
Hey man keep up the good videos. Can anyone point me in the right direction, I've got a mid drive motor on my bike. Everything works, I lift my back wheel up and it spins perfectly, but when I sit on the bike the motor just shudders and doesn't have the strength to drive forward. Any ideas??? Does it sound like it's the clutch?? Thanks
The censor width was my exact problem! Thanks so much!
Hi!! Got a problem with bike shutting down the engine power when I go up a hill or having heavy wind, anyone that knows what that could be?
what can i do if i dont have an ebike store near me?,since u say its better to shop for a bike in a store rather than online
Why not build your own and learn. If you have bike now,your half way there. Get a kit to fit and build your own ebike.Check out Bafang mid drive.That way you learn how to fix your own ebike.
Don't get an ebike.
My bike is half way on the road cut to power of and if i put one second power for charge its work do you know whats the problem thanks
Like you said some useful stuff but I came here looking at how to fix a problem not troubleshoot poor design issues....
Had my bike for a few days and I made changes to a few things like placing a dam spring behind the magnet plate....
But when it comes to the engine itself you didn't give me any info that was helpful... My bike is make extra noise when I ask her to give some force... It's kinda grinding/whiting noise I cannot place... I felt like it was the gears but they seem fine.... Re-greased the gears and inspected the mint coils.! Placed back together carefully and she still makes this noise...
Can you check the motor,can you apply 48v directly to motor to see if it is ok
how could i fix my horn on my riding times z8 bike
Hello, can you tell me what error code 36 means? The bike makes a weird noise from the motor then it cuts on and off repeatedly. I’m lost. This is a new bike with only 45 miles on it. The mileage was put on over the past month. Please help 😬
I purchased a new Aventon Level E Bike in Mar 2022, it has the cheap
zoom fork, after about 2 weeks the front fork makes a clunk sound when
going over some bumps and it's
pissing me off, it does not do this when it's locked out though, does
anyone know what the issue is? Or even an upgrade fork the would fit
this bike? Thanks John
Do you use the ebike electrical testers, e.g. Romia to troubleshoot problems? Is there a wire harnesses that adapts the testers connector to the ebike controller cable and also to the wheel motor (pony) cable?
