This really helped me, I had no idea what to even check and Jonny , you put it in perspective for me and it was my brakes. I got my e-bike working because of you. Thank you so much
😃
You Sir, are a legend. Had my Kalkhoff booked in for what was going to be an expensive repair. Checked all connections and the head up display wasn’t quite connected properly so the motor wasn’t connected to it! All back working now thanks to watching your video and listening to your advice.
Thank you so much! My power assist and throttle weren't working this morning and this video gave me the solution I needed - The magnet on my hydraulic brakes had shifted. I screwed it back on and it worked perfectly again!
I wanna thank u , my boyfriend has an eco motion electric bike ,and it just stopped working , and I seen ur video so I showed it to him and the first thing he tried , it worked .
Lol
Awesome....education is the only positive on the web!!! Just to much crap otherwise...
😊
My battery indicaiter lights won't come on and it won't put out anything.anything I can do?
@@user-ut1zg9iw6ican’t get it to pull up said how. Do you fix it
oh my god cleaning out the battery connection on the frame itself worked for me. THANK YOU!!!!!
Hey Johnny,
john e. here with a thank you for helping me to diagnose power loss due to a loose connection between motor and rest of bike multi-pinout connector. Must have worked itself loose.
Question: my ecotric rocket is 3 years old and recently the motor always operates at approximately level 4. It has 0-5 levels. But even at level 0 it runs up to 17mph as if it's in level 4. This happened recently I believe after a rear tire change.
Another absolutely fantastic vid!! Please keep nerding out. Thanks from Seattle
Thanks Mike!
Welcome, really like your can do attitude.
@@mikekearsley2407 😀🙌
Thank you for your tips and advice. Your a big help. Am new to the Ebike world. I had a bad brake connection. Where it wasn't allowing my display screen to come on. Thank u again. A fan from here on out
What did you do? My screen is off also
@@nicholasrivera7089 check your wires . Brakes. Etc. That was my problem.
Mine gets error 16 so cuts when doing both breaks and it only supports in a certain gear also its a brand new bike . Replaces many things including the speed sensor and new shifters but still acts like that?
Thank you for your time, info and expertise. I have a Rambo G3 750 bafang. I'm having problems with the controller turning off during operation typically under a heavier load or uphill. My battery connections seemed good and my voltage is good on my. Do I need to check and likely start by replacing the controller in the motor
Thanks alot ! This video helped me fix the motor issue
That Jamis on your website looks so nice. Added to my cart I may pull the trigger.
3:24 thank you so much for this video... My Dad's e-bike had an issue, the problem was simply to check the wiring.
Hello Terry I also have similar issue I don't know if you can help me out
@@elijahkuti9294 What I did was unplug the cables and plug them back. I don't know if that will work for you.My advice is keep watching videos or go to a local bike repair shop for help.
I was all bummed my bike crapped out and was looking for more technical troubleshooting, thought what a worthless video, Duh who wouldn't have checked their connectors and cables, stoopid! Been through the continuity testing of the mosfets, etc. I totally thought I wasted my time watching your video! Decided to go back out in the garage and check all my connections... Eh, you nailed it brother! I'm eating crow. Sure enough the axle wasn't quite tight enough so it spun a bit and kinked the cable that goes through it, I straightened it all out and she fired right up! @JohnnyNerdOut for the WIN!
Brilliant video.saved my bacon thank you so much..from the UK
Johnny love your videos. I have a question on a new build with a bafang 750 mid drive. Everything seems to be working, but only for like 1 second then motor slows way down, if let off of throttle when hit I again get full power for about a second then it cuts back to barely working again. Any help would be greatly appreciated , I do have another bike with all the same parts so I will change 1 piece at a time to try and find the problem but you might have seen this before.
great video. very helpful.
Thank you,you saved my day , simple but useful 👍
Thanks for all you do Do when i turn my battery on the 3 red led's come on for couple of seconds 2-3 seconds then go out any ideas mate
Detailed video!!!
However, I have a situation I need advice on. Got a used Panasonic ebike without it's charger and wondering which connectors to use as charging points. I see: T - S C + and not sure what else to do as I have tried the + and -.
Please help advise.
Thanks a-bunch!!!
Appreciated John, Thank You for Sharing.
Very welcome
Hello, maybe u can help me please. I have a daymak EM2 2020 and the bike will not shut off. Have to use the breaker. U know why?? The bike runs great .
really good video! Thanks! i have the electra townie 7d step thru and i have the 3 red leds lights flashing.
any idea?
Excellent video.
Leaving the battery on the bike for charging protects contacts.
Chaining up the bike to stop it falling over , also protects contacts.
Cheers mike
water is in the controller the red light is on what to do
Ithink that there is water in the controller
😊
😊
Red light is on
Thanks it is a PA and Throttle. Battery is brand new but could have a defective cell. If the controller easy to check?
Great vid, Good idea to check the screws on battery one fell out on mine lucky I seen it and another was loose,
Hey Johnny, thanks for all your vids mate, there gggggreat! I'm in the UK Newcastle upon Tyne, I've made my own ebike from an old trek mountain bike, I love it 24 mile a day. I've done 1100 miles on the bafang 750 watt.
Today it has come up with error 12 motor kept cutting out then working again, did a weird peddly juddery thing. I did the off and on again thing and it worked then stopped. Finally I realised that the throttle would still work with out any problems. Luckily I had enough charge to get home on just throttle any ideas. It's really wet and muddy my bikes getting caked everyday I'm hoping it's some water in somewhere causing havoc???
Hi. I'm having trouble with my fuell flluid-1s. Belt drive ebike. The company haven't been able to help me with the issue. I think the chain ring bolt might be lose? The pedal crank has about 1/4 inch of slack on mostly the right pedal when it's at the highest postion. It's this way with or with out the motor turn on. And pedal it backwards there a light blockage of some kind. It pedals past the blockage but it's there. Any suggestions? Thanks. Steve
Thank you 👍My issue might be severed cord. It seems only the black outer covering is cut in three places. I don't know how that could have happened but that cord seems responsible for my front break. My problem is that the wheels don't move as easily as before and the pedal assist isn't as strong as it was, as well as the throttle slows to a stop. When the wheels kind of lock and are hard to turn, the assist doesn't work and sometimes it works suddenly causing it to jerk.
I wonder who I can take my bike to to look at it. Are there places that take care of bikes?
We bought two Lectric XPs. If yours arrives and works out of the box count yourself lucky. If it does not you'll spend a few hours underneath a brand new bike following emailed trouble shooting guides. If you fix your brand new bike you're lucky again because it's a high hurdle to get Lectric to get a new, working bike sent to you for the good money you've already paid. Things happen, we all understand that. The true measure of a company is how well it puts things on track, and makes a customer happy when things do go wrong. Lectric e-Bikes has a ways to go on this count. Be advised.
Really good to know
Hi thanks for your help.i have and ebake but when it start after a minute it get off alone like the battery goes flat at one
great, simple troubleshooting nthat applies for any ebike...good stuff, thanks! momma will be back in the saddle by noon!
Our Aventon Pace bikes were flooded in Ft. Myers Hurricane Ian. We rescued them the next day and washed them off. The batteries were destroyed. Took them to a bike shop....they cant get them to turn on and advised trashing them. Any thoughts on how to proceed? They are just trying to get us to buy a new bike.
I've watched a few videos recommending re-packing the motor with grease after the first 600 miles. Is this something you recommend?
I would. 600 might be early. But every 2k or when you hear your motor sounding “off” whichever comes first
2 minutes into your video and my bike is fixed! Thank you sir!!😊
I have Raleigh Stow E Way. There's something up with the power, it comes on then it stops afrer about 30 secs and sometimes it won't come on at all. Was this the same problem you had?
JohnnyNerdOut WOW this video saved me the first thing I tried (brake cable not aligned properly on handlebars) saved me thank you so much!
Suddenly my new Emojo caddy pro gets no power to wheel but controller lights up. I will try your video points
Hi Johnny
I've got a Cyrusher Ranger, great bike but pedal assist has stopped working. The bike rides well on the throttle and cuts out when I pull the brakes, so thats OK but just doesn't put any power assists down when I start pedalling, I wonder if you have any idea what that could be?
Thankyou
Sandy
Pedal assist sensor or controller likely
Thanks so much.Very infomative about ebike battery chargers
So I ordered a new controller and hooked everything up and tried to run it and it wouldn't even power on so I tested the wires from the controller to the throttle and they were dead. Any suggestions on what would be wrong ?
thank you Johnny. I just removed the broken brake cable plus some small components, and while just started to riding the biycle, I pressed the brake and suddenly no throttle. I opened the youtube immediately, watch your video and you mentioned something about the brake. I reinstalled the brake component... whatever it is called in place, and walla, the bicycle ran again.
3 minutes 38 seconds in and my bike is fixed! Thanks so much!
I adjusted the brakes on mine, took up the free play on the levers with an allen key, and unwittingly activated the cut off to the motor !!!! When you pull the brake lever, it cuts power to the motor for safety, by adjusting the brakes a little too much, the cut off switch was permanently engaged. Just backed it off a little and all was fine.
Hello all
Have got this mountain bike with and e conversion kit on it and having no joy solving the power problem have had all the silver box checked and all power is still live from there and the battery just not powering up, my lad said when he reconnected the reds it give of a lil spark, any help will be greatly appreciated. Have just tryed to test any power going to it with a pen tester and there not power at all? Help.
Thank you so much for the info !
My issue is the pedal assist surges, this started just recently. I bought bike new last year but when using full throttle mode, runs smooth. I have not unplugged brake sensors yet.
Hi, I bought a battery and charger for a pre-owned Geliesen Ebike. When I received the battery, the bottom doesn’t have the pin connectors. It’s just metal on the bottom. Is it possible to still use the battery with this bike?
Hi. Maybe you can help me troubleshoot.
I have a converted e-trike with an MXUS motor hub that uses a 52v battery. Recently, any time I'd ride it, the e-trike turns itself off, then I turn it back it turns off again, then I turn it back on but won't come on unless I press the button 10x. Then it will come back on but none of the sensors work, then it just dies completely. To get it to remotely work again, I have to unplug the battery then replug it in, but it will not stay on long.
The batteries are still good, (trust me, I spent $600 on a brand new battery and it's still doing that), they're fully charged, the voltage is fine, and so far the shop that did the conversions have found nothing wrong with it and it works PERFECTLY fine when they use it, but it immediately starts doing it to me when I bring it home.
I tend to ride it at max speed, but this has never happened before, and even when it's not max speed it still does it. Is it something wrong with the hub, the motor, the display, the wiring? I need help figuring this out because this trike is my ONLY mode of reliable transportation.
A fine video Thank You Kindly - I've enjoyed my Swagton for 1 year yet after slightly adjusting the hand brake it has show no power what so ever the past 6 months, What adjustment should I make to the Brake Connections to correct, Thank You.
It woukd be nice if he responded. . Did you figure out the issue because I think I may have the same problem but idk. Showing an error code 10. Bike will not go and also my head light is out. Leading me to think it is the controller
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? Could it be the prongs arent lining up right? Any advice will be very much appreciated...
You are THE MAN! My RADCITY lost power about 5 miles down the trail. Had to hump it back to my car. Spent some time checking it over. (What do I know about ebikes?) Watched this video and where you talked about the brake cutout got my attention since the power failure happened right after I applied the brakes. Went and checked out the rear brake lever and noticed that somehow the throttle cable had got caught in the brake lever opening. Releasing the brake lever was squeezing the throttle cable. Worked it loose and bing-bang-boom. Back in business with full power! Thanks so much. Like to buy you a beer and a good cigar.
My man!
Have a friend with a 2019 Rad City. Lost power. Rad tech support sent a new controller. Nope. A new wiring harness. Nope. New throttle cable. Nope. Got to be the battery then. Can't get batteries right now! Sorry.
@@tomobrien1814 in a pinch. Any similar voltage battery will work 👍
@@JohnnyNerdOut I think Rad would have sent one if they could get one.
This is super helpful!! Thank you very much, from New Zealand!!!
My custom built e bike died when I was braking the regen came on for half a second then gone I look down to a blank display it will not power on anymore the battery is fine and at about 80% -85% charge my 12v system gets it's power from the controller and all the lights work just fine. I've only done limited testing on the controller but I think it is the display because the on/off is connected to it and if turning the key off cuts power to the display then that on/off button may do the same.
I have a 2019 Giant Trance electric. It suddenly wont turn off. I’ve removed the battery and checked the fittings but still having the issue. Any idea? Thanks!
Please help me, is the DC converter needed to turn on the bike? they send me 2 new controllers and a battery but still it doesnt turn on, what should i check more? one night i put it in the garage and the other day it never turned on again...only part that hasnt been replaced is the dc converter, cables seem fine, and what about the motor? i tried your battery trick and everything else..
Is it easy to change a hail long 20ahn cradle replacement ! Got same connectors only worry about connecting to main line power lines got one red wire and the normal black red connector ! For BAFANG 1400 watt midrive BBSHD Same as the original it came with ! If possible what is the red one with no connector please ,do I rewire the red one the others have connectors ? Thank you !
I have a problem with headlights can be brushless? All contacts and connections are ok cables no damages
Hi got hitway evoke and the battery sign is up and checked all connections ran through your video any ideas greatly appreciated
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??
One of the contact points on my cradle is mostly burned away with even the plastic surrounding it being deformed. Is it possible to buy a new contact point or if not, perhaps just the cradle itself?
Thanks
hello. my nakto camel 250w 36v bike has a good battery 41 volts as shown on ohm meter, and shows full charge on throttle lights. once i go to ride it will start to run down quickly. then it will cut out. once i turn the key off and back on it does fine but then will cut out again. could it be a bad battery but still read 41 volts? or coud it be another issue? the bike is 2019 and hasnt been rode much, but also was not charged regularly as it should have been. thanks for any help. i just bought a pair of these bikes from elderly couple on marketplace. whats weird is that they are both the same model but have different battery pack sizes. one bike is older than the other. both bikes read 41 volts and the other bike does fine, but the older bike (2019)model is the one with issue. im new to ebikes and i know nothing about them. very sad that i have trouble before i can enjoy the bikes
Okay it's not even been 45 seconds into the into the video and this guy already got money as a sub met Clint Eastwood will live forever
i have a skylark so i don’t think i can remove the battery but everytime i try to twist the gear to go forward, it works for 1 second then stops. What do i do about that? thanks !
Can I ask about the k800 fat bike? I just swapped out the display because the other one. The screen was half burnt out. It's the M5 e bike works with the old display as soon as I put on the new display the bike does nothing. I've adjusted the setting and still nothing what am I doing wrong
thank you this really helped me
Hey bro I have a sunmono cargo E bike and the pedal assist and throttle have stopped functioning properly they are stop starting do you have any suggestions I have no ideas about ebikes at all
Hi Bud, just subscribed to your channel here’s a good one for you, I was replacing the crank bearings in my Giant Stance E+1 all good then I noticed that the positive & negative connection to the motor had a small amount of corrosion starting not bad but decided to change it. Unfortunately I cut across both wires at the same time there was a short across the cable’s ( not connected to battery ) didn’t release the motor must hold a small charge. Now when all reassembled the bike trying to go but stops after a second or so what will I have blown up inside the motor, disassembled can’t see anything burnt or melted really annoyed with my ignorance.🤨
Happens all the time! Don’t feel too bad. Might have burnt your controller possibly.
I have an Ancheer and the power will shut off suddenly with a full charge. If I leave it alone for a couple hours all the power comes back on. Is it the controller or battery?
I have a yose power with an error 09 and have replaced the display still the same. I’m going to wait until weekend until I start breaking down the kit.
johnny I need help, i have a new battery that wont work but the old one still does. Bought from alibaba it puts out correct voltage and polarity is right, still cant get it to power on bike.
Would you be able to help me open up a Bafang M620 and grease the gears?
Hello, I have no idea what it could be, but my fat bike (ouxie v8) is working perfectly, charges well and everything works, etc. until the battery drops below a certain percentage, approximately after 15 km of riding, then it still shows on my screen It seems to have around 46 volt output, but as soon as the support starts working it cuts out after a second and the lights that indicate how full the battery is no longer work, I have never actually had this problem but it came out of nowhere. Do you know if something like this can be solved and if you have any tips, that would be great!
I have a Phantomgogo R1 36v scooter. When I tested the 5v red wire coming out of the controller I found that the 5 volt Red Wire is pushing 17.44 volts. I am afraid of connectiing the.controller to the throttle because I do not want to damage the throttle. Is this high voltage normal or is it a defect? Will it destroy my throttle?
Hi Johny, I have e-bike. Flyer Uproc7 I can't figure out what could be wrong. I have the battery fully charged the wires have been checked and the display shows me that the battery is empty and in red. It shows me one error 67-32 according to the service book. I don't know what to do? Can you help me??? All assist functions are in OFF mode.
Thank you, just a little info went a long way.

Hey John, I have a question. can l replace any lcd display with throttle on my ebike? My ebikes now doesnt have throttle. i want to upgrade and put throttle on it. is there any points you can give me before doing the upgrade? last thing, changing my display will it affect my controller?
Not just any display with work. You will need to make sure it’s compatible with your controller first. If you bought it complete. Ask the manufacturer (brand) what options you have. Replacing controllers can be a headache especially if the brand is not helpful.
Hi Johnny. I got the isinwheel M10 Commuter Ebike only 10 days ago. My battery is fully charged, the problem is when I turn the throttle, the motor just lurches for 1-2 seconds then stops. If I get off the bike and lift the back wheel, it works fine, but when I sit on it, the motor stops after a second. I'm only 130lbs and the specs say up to 330lbs, so its not my weight. any suggestions?
My wire burst short circuit and try to reconnect the fine 5 wires but it didn't have power. What shall I do . Does it have fuses somewhere . My Bafang display is C965
Great video. Hi I'm Lg. . I have a Haoqi H1000. My voltmeter says 52 but the button on the battery that shows how much power high and low is not working ... Is the battery good but that power light stopping the bike from getting power. Please any suggestions
yes Johnny, Id like to speak too you about my e-bike, the motor isn't turning the wheel, it's sounds like it's missing a gear! any help would be appreciated, as the e bike is my mode of transportation!
What if the key lock component is housed separately such that when the top cover four screws are removed, the key lock component is residing in a separate compartment housed in plastic cover adjacent to the main plastic casing? And battery is slided into the battery holder bracket of the ebike?
Mine stopped working after a wash 😤 so im assuming the control thing on the handlebar was not fully waterproof. Now it wont turn on but the front light in always ON and i cant turn it off. So i just unplug the display for now to turn off the light but obviously the main concern is i cant turn on the motor..
My bbs02 seems to give hall sensor code 08h, when it gets too cold (bellow 2-4 degrees C) is this common, my bbshd is fine
Not that I’m aware of.

My ebike cut out yesterday and I disconnected the brake Sensor from the control and now it works
I bought an ekxbike x-21 and the motor makes a horrible sound when the throttle is engaged. It sounds like gears grinding
Any idea of what would cause this?
Hi I have an AOSTIRMOTOR so7 and have an error 30 code now, checked everything and still won't work, I know the speed sensor is messed up but the bike was working still with that cutting on and off at times, but man 4 days now and I cant figure it out! My only source of transportation too!
had an error code 31 (communications error ) the lcd screen lit up like normal but i noticed the battery level indicator normaly like 5 bars or batteries in the battery shaped indicator on lcd was just an empty rectangle. took m620 bfang out checked everything . now no power at all to the display .....help ? thanks
Thank you so much one of my cables was unhooked
Great video!
I disconnected brake, the ebike works again. How can I fix the brake control? Do I really need it? Thank you!
You don’t need it. Do you pedal and brake at the same time? No
Hello. I have an electric moped and I have this problem: it doesn't go, it doesn't show the brake sensor on the speedometer and it doesn't show speed mode on the speedometer. What could be wrong, can you help me?
morning nerd out guy! Question, bought bike (ecotric) w/fat tires (about $800 model - never ridden the bike, the battery was fully charged from the box - and will show fully charged when on charger - take it off the charger and it shows nothing - the display on the handle bar will not come on - think its a bad battery?
Get a volt meter and start detective work!
Really appreciate all your videos! Not sure if you're still replying to videos, but I have a problem I have yet to see a video on. My bike has de-rated itself from 42km/h to 21km/h. Was like that for the first 500km as well. Then like a flip of a switch back to how it was. I don't know how I got it to go fast the first time, it just kind of did it on its own. Messed with display settings to try and get it back with no luck. Controller, display and motor inside all look good to me. Any ideas?
I’d do a firmware refresh (assuming you have a Bafang bbsxx?)
I was putting a 1500 hub motor on my cat trike. I turn the monitor on and was in the middle of putting my past word in when my phone rang. My grand son pushed the led pad buttons and it put a pass word in and I don’t have a clue what it is. Now I can’t get in. Do I have to buy a new monitor. Or is their a code I can put in. I bought it on line and the company I bought it from is no help. I don’t know why I put a code in anyways. I have to trike one is mid drive and this one has a hub motor. Can you help me or point me in the right direction
Could also be your display settings. which I am having trouble with.
My Astro pros hydraulic disc brake sensor got chewed by a puppy. The bike turned on once after that but once powered down it will not come back on you think that sensors the issue.
Ok, i know i am seeing this a little late, but my battery is 48volts and it is putting out 58 volts, could this be the issue?
Edit: My issue is that every time i try to go a little too fast, or accelerate a little too fast, then the battery fakes being dead, it isn’t actually dead, but my throttle display think it is, i have been having this issue for a few days now and i just cant figure out the problem.
