In this video, requested by my subscriber is to show how I installed the qs205 5000w with a 150mm drop out into a aluminum frame with a 135mm drop out.
Mate want to say how much I appreciate you showing me and everyone out there that you can get over a 3kw 135mm dropout hub into your 135mm mtb frame! Reassuring video man, I myself have built a fair few of these builds and have molded slightly to get the job done, but none 150mm so really been mad help. Always avoided going over a 3kw hub for that reason. Pushing 12kw into em lol. The 16mm washer on the freewheel side and flat torque arm you get with the motor on the right side majorly will save me time. Again n again u explain it all in a depth which people understand. I'll update my progress on Facebook, sure have made it alot easier. Great video Ebike life 👌 👍 👏 🙌
@@E-bikeguy the QS 205 looks a complete beast. Sitting next to my 3kw generic motor on my current build, makes the 3kw motor look like a baby lol. Literally cannot wait. Thanks again you the man 🙏👌👍
"More than one way to skin a cat"! Grandpa would say looking at your clever battery drill to get her done without another trip to Home Depot, field ingenuity at it's finest
The amount you have invested in that bike opens the question about where is the dividing line between using a basic mountain bike and buying a Bomber style frame kit as the foundation for the build. The pros are obvious but the cons might be it no longer looks like a bicycle and perhaps it will draw more attention with no motorcycle license plate. It also is heavier which while stronger, it makes it slower. But it can take the 273 8 kw motor so its not slower anymore. Lol I think one of your subscribers is making one of those now.
Yeah you right it's in the works for him he so excited to get that beast up and running, and for ad I know he will be the 3rd person to have a qs motor in a MTB frame
@@E-bikeguy, I uploaded a video of pictures of my girlfriend’s $600 (+$400 in upgrades) scooter so you can see what I was working on. Its a perfect match for the local laws here in the Philippines. But if i took a different pathway and bought 7KW motor, 200a controller and and as big of a lithium ion pack as i can fit in it, it would be $3000 ebike instead of $1000.
Get a tannis liner for the rear tire to help prevent flat .... That way you don't have to go through all the trouble of taking the rear tire off. Sweet bike 👍 the tannis liner smooths out the ride too.
thanks, i was looking all day for someone installing more than the single speed freewheel. I still dont have my rear brake installed because the disk always touches the cables and i dont know why. I bought the motor used and its also an old one like yours.
@22:35 probably thinking of flange nuts. Flare nut is for flared tubing fittings. The serrated flange nuts are nice because they also serve as locknut. The secondary function of the torque arm is it will hold the axle in the dropouts even is the axle nuts do get loose. So you will notice it before the wheel has a chance to shift enough to cause a problem. You have those torque arms mounted in the perfect orientation, which does two things: 1. Holds the axle in the dropout. 2. Changes the torque from something trying to spread the dropouts open to a forward force at the axle and reward force at the 10mm bolt, when accelerating under max torque. With regen the forces are reversed but regen is not going to be 16kw. That little comma shaped torque arm, even though not needed, could beef up the side with the trailer hitch torque arm a bit and give some mild steel for a serrated flange nut to bite into. The serrated flange nut will chew up the raw aluminum each time you undo it so it needs some sort of steel there on the outside. Just depends if you can find a clean spot to mount it that doesn’t interfere with other things on the dropout.
As always thank you for that info, every time you comment I get more knowledge from you. I figure them torque arm is in a good position to stop the axle from turning and its been holding good under hard acceleration.
@@E-bikeguy yes, they are perfect. My electric scooter has horizontal dropouts and the same torque arms you have mounted horizontally too, so it does the axle retaining job (most important in my case) and spreads the force from my beastly 500w motor and 32a controller.
@@E-bikeguy I'm confused about silicone wire thickness. I have a 22a front wheel controller and a 22a rear wheel controller. All my batteries have 14awg wires and 30a continuous. One battery kicks off if climbing a hill, so I am going to run 2 duplicate batteries to get 60a. I bought xt90 connectors and have both controllers wired together. Do I now run 12awg for the 44a ? Is it better to separate and run a battery with each controller and stay with 14awg?
One of the most frustrating jobs to do of Looking for Right Rear Drop Outs. Had to Toss a few to the side due to motor hub wider, along with the size of bolts. Front wheel more Universal but it's rear drop out you have to find.
Hey @E-bikeguy i am inspired by you and i am planning on building an ebike similar to yours i was to use the QS 205 but by bike's dropouts are 190mm is there anything i can do to make it fit? or do i have to forget about the QS205 and use a weaker motor with 190mm dropout? thanks in advance for your response in advance
@25:45 oh yeah, i can see how tight that clearance is and why you added the spacer washers. It got me wondering which caliper QS designed that for that will have adequate clearance without the spacer washers. I also looked to see if any 280-300mm rotors that would get the caliber away from the hub but all the pictures i see show the 205 with a standard (180mm ?) rotor. It would probably work with very small clearance since the hub would move out snd the caliper wont move in, but the caliper would need to be set with the inside puck fully compressed so it just clesrs the rotor, then the outer puck does all the initial travel. Then from there both pucks would move in equally. Probably the only benefit is it gets the rotor bolt heads 1/16” further away from the motor wires. Thats the place i want to see more gap. Lol
I've got an issue where I bought a Bafang G062 1000watt motor and 30amp controller and a new display to replace my Aventon Aventure 2 motor, controller and display. I did it because it's locked at 20mph on throttle, way too slow. Anyway, I bought the 175mm motor instead of the 190mm version. I totally slept on that. It came with beefy torque washers and nuts, but I had to put the torque washer on the outside of the rotor side because the calipers were too far away from the disk and put the torque washer on the inside of the dropout of the freewheel side, and now I can't get 1st or second gear no matter how hard I mess with the derailleur. I Was thinking about putting washers behind the rotor like you did, but after researching that option I hear there's a good chance you'll shear the rotor bolts sooner or later with a hard stop. I don't know if I need torque arms; the motor pulls 1475 watts and will do a top speed of 32mph. Your bike, from what you described is probably twice as fast and torquier as mine, do I still need torque arms or are the torque washers enough?
Ok that you for your comment, no you don't need torque arm the washer will do just fine. And far as the rotor goes if you get longer screws you won't have a problem either.
It will be interesting to see how the Sabvoton flux weakening responds. Sabvoton uses amps, Votol uses some number big numbers nobody knows what they mean. I have no idea in the Sabvoton except you add flux weakening bit by bit until the top speed gain isn’t worth the loss in torque and the battery voltage sag from sustained high amp draw. I don’t use it because my 500w motor uses 1500 watts to go base speed, so flux weakening would overload it. Plus on the Votol the motor sounds strange in flux weakening, no longer silent.
I just ordered a 12t rear freewheel. Found it on eBay. Combining that with a three gear front with a 48 tooth big ring should help me pedal past 18mph.
I’m confused as… I love your content but where is the part where you actually explain how you got the 150mm to fit in the 135mm dropouts? Does anyone know ?
Dear E-bikeguy: How much is a motor/wheel like this with the recommended contoller approximately? Is the standard kit controller any good? How about the spokes, are they strong enough? Thank you for replying!
The washes are there for spacing. I mean, if your drop out is too small. Of course, the wheel is not gonna fit. But my torque arms are usually bolted to the frame of the bike so you might have to email me a video. What your Drop out is doing. Because if you tighten that wheel down tight enough, that wheel do not suppose to come out that drop out. What kind of a bike are you trying to put that wheel on?
I still don't understand how you fitet the qs205 motor to the 135mm dropout. My qs205 motor is to wide to fit between the dropouts, have you bent yours?
No it should slide in with little effort, it depends on what frame you have also, I have another video on this build where I built another one for a customer
As long as you do not bang out the sides. The spacing for right rotation of motor hub can go out of whack of jus the smallest mm. It will work jus fine if you had to do this but it's jus a matter of time the hub gets warped and magnets start heating out the form. I did this to a normal bike in my teens ofbanging out the side mounts to fit in this BMX wheel. In a month the wheel spokes snapped off.
@@E-bikeguy Of my experience I find myself to move along next bike frame if not perfect fit so you can tell why I only using 2 e bikes since Feb2022,lol. The Turbo Boost e bike has 2 motors but on the standard single front shocks MTB. The other 1 or the 1500watt CKit I happen to have a similar frame of the Sur Ron bikes, the Dual Hardtail 2 piece from in a NEXT Power Climber and this type of frames the best one to use but those frames rare of only seeing in Craigslist but those Dual Frames make e bike suspension like. MercadesSport. The comfort and flowing motion will spoil you. Jus not right to use a Rear on those Next Bikes , the width is smaller then average due to being 18 speeder.
@@E-bikeguy But I've been using the 2.125 width rims. Going to see if the smaller widths rims can fit besides going down magnet size of the 1000watt and lesser .
Oh, I'm going to even try to use 3 inch fat hub for rear of the NEXT frame of not adding on the flywheel. I do not use PAS majority of time unless power level low, use my e bikes like a moped scooter
Thank you so much as far as I can see the newest model is very easy to programming to once the hall sensor setup is done …….also love your channel and content keep it coming
As I’m watching your video I’m a welder for 12 years but don’t have a welder lots of good info on torque arm you are like MacGyver with the screw gun. I built a 5000 watt motor kit with 150 amp controller I need to do some modifications. I need your advice on a battery that won’t take a charge I went down to 2% when I pluged in the charger instead of 2red lights it had a red and green
Ok If it's flashing a red and green light try to keep the charger plugged in, it's trying to take a charge once the voltage is up on the battery it should stay a solid red light
@@E-bikeguy after few days of charging still not fully charged voltage meter reads 60plus. volts but when I put on the bike and get into the settings to change the voltage with a52 volt settings on display it reads 100% and when I went to 72 volts it was 57% this is a 72v20a battery 🪫 thanks for your fast response
Hey brother! I got joke🤣🤣 I think I got a good deal? 🤣 QS 233 and monitor, and sabaton 100 for 489.00. 135 drop out. Was wondering if could make it 175 for fat tire bike? Term your looking for.. not give it Gas.. Give it the juice! Lol just made up🤣🤣
Your videos are top notch man can I ask where you got your qs205 3.5t from? I see them on aliexpress but is that safe like or a specific seller? Also I noticed the bicycle is using your own calipers rather than what comes with a kit..how so you get the motor to cut of been as custom brakes don't have the sensor?
@E-bikeguy Speaking of battery. Can my battery and controller still be able to run this motor if it doesn't meet the requirements? My controller is a 48v 45amps and can only do 2000w. But I'm thinking i can still run this motor and it won't stress the motor too much as well. Therefore it won't overheat the motor as well. Is what I'm thinking.
@doomslayer1676 it depends because of the phase angle of qs205 is 220 some controller can't go that high so you need to get the sabvoton controller 7245 to detect offset angle of motor to get max efficiency
@E-bikeguy Yeah but what I'm saying my controllers maximum potential is 48v at 2000w 45amps. I was told the only limiting factor is my controller and battery. I'm buying a QS motor 205 for FUTURE upgrades down the road. But I want to know if I can still use the motor with my CURRENT controller and battery for the time being. The controller allows me to do hall test as well through and app. I use a Sabvoton controller. 36-72v 2000w at 45amps. This is the controller maximum performance but its currently programmed to 48v to be able to accept my 52v battery. Will that^^^^ Work with the QS Motor? Even though the motor is rated for 3000w-5000w. My current set up of 2000w should still be able to spin the wheel at the very least.
yo great video :) i think my dropout is currently 135-140mm too and i have 142mm hub motor on it, so can i upgrade to hub which is 155mm? i think i need to bend the aluminium frame like 10-15mm or so.. it would be very tight fit. would it work?
@@E-bikeguy the kit im looking at has 1speed casette, but i still think i would need to bend or even grind something.. just cant find 135-150mm motors that are reasonable priced, they all have like 200-400dollar shipping which is BS.. well there are some good kits but they have bad controllers and i want to buy motor and controller seperate, so you happen to know where i could get ONLY the motor 3000w 72v ?, everything in aliexpress have ridicilous shipping prizes
Well I used to be a welder by trade then I picked up the mechanic skills when I was 14 by my next door neighbor, they was into racing from There on I been working on my own stuff I have a gmc yukon turbo and my kids use to be in motocross so I work on their bikes, I'm say I'm more of a Mr. Fix it DAD

@@E-bikeguy after few days of charging still not fully charged voltage meter reads 60plus. volts but when I put on the bike and get into the settings to change the voltage with a52 volt settings on display it reads 100% and when I went to 72 volts it was 57% this is a 72v20a battery 🪫 thanks for your fast response
No problem I'm here if you need anything else
Hey brother! I got joke🤣🤣 I think I got a good deal? 🤣 QS 233 and monitor, and sabaton 100 for 489.00. 135 drop out. Was wondering if could make it 175 for fat tire bike?
Term your looking for.. not give it Gas.. Give it the juice! Lol just made up🤣🤣
🤣🤣🤣
Your videos are top notch man can I ask where you got your qs205 3.5t from? I see them on aliexpress but is that safe like or a specific seller? Also I noticed the bicycle is using your own calipers rather than what comes with a kit..how so you get the motor to cut of been as custom brakes don't have the sensor?
I have a seller, I'll send you a link. Also I'm using zoom hydraulic brakes off of ali express

@E-bikeguy Thank you much appreciated. So with the zoom brakes does it cut the motor when you brake since they don't have sensors?
@m A yes they have the sensor
Wow pas 1 does 20mph ? That’s insanely awesome what battery did you have paired with it at that time ?
It was a 72v 40ah battery I got from aliexpress that I had to modify it
@E-bikeguy
Speaking of battery.
Can my battery and controller still be able to run this motor if it doesn't meet the requirements?
My controller is a 48v 45amps and can only do 2000w.
But I'm thinking i can still run this motor and it won't stress the motor too much as well. Therefore it won't overheat the motor as well. Is what I'm thinking.
@doomslayer1676 it depends because of the phase angle of qs205 is 220 some controller can't go that high so you need to get the sabvoton controller 7245 to detect offset angle of motor to get max efficiency
@E-bikeguy
Yeah but what I'm saying my controllers maximum potential is 48v at 2000w 45amps.
I was told the only limiting factor is my controller and battery.
I'm buying a QS motor 205 for FUTURE upgrades down the road.
But I want to know if I can still use the motor with my CURRENT controller and battery for the time being.
The controller allows me to do hall test as well through and app.
I use a Sabvoton controller. 36-72v 2000w at 45amps. This is the controller maximum performance but its currently programmed to 48v to be able to accept my 52v battery.
Will that^^^^
Work with the QS Motor? Even though the motor is rated for 3000w-5000w.
My current set up of 2000w should still be able to spin the wheel at the very least.
@doomslayer1676 oh ok as long as you can tune the controller then yes you can use you current controller
yo great video :) i think my dropout is currently 135-140mm too and i have 142mm hub motor on it, so can i upgrade to hub which is 155mm? i think i need to bend the aluminium frame like 10-15mm or so.. it would be very tight fit. would it work?
Yes I really didn't need to Bend the frame so yeah it will definitely work😎
@@E-bikeguy the kit im looking at has 1speed casette, but i still think i would need to bend or even grind something.. just cant find 135-150mm motors that are reasonable priced, they all have like 200-400dollar shipping which is BS.. well there are some good kits but they have bad controllers and i want to buy motor and controller seperate, so you happen to know where i could get ONLY the motor 3000w 72v ?, everything in aliexpress have ridicilous shipping prizes
Ok well I get all my parts from ali express, the motor should be only 357
Oh ok yeah they get you on shipping, so you want the 3000w motor? 72v

I took it off just to make this video lol well I might as well change the tube
Do you think it would be possible for me to text you a couple pictures of my battery I'm working on for your advice? Thank you for the consideration!
Sure let me know when you ready
Ok when I get home I'll get back with you
@@E-bikeguy cool I appreciate it!
That happened to me

Are you a mechanic?
Well I used to be a welder by trade then I picked up the mechanic skills when I was 14 by my next door neighbor, they was into racing from
There on I been working on my own stuff I have a gmc yukon turbo and my kids use to be in motocross so I work on their bikes, I'm say I'm more of a Mr. Fix it DAD
@@E-bikeguy Cool, what do you do for work if you don't mind me asking?
I do small engines on part time jobs when I'm not working on ebikes
I have a 29inch in my qs205 want drop in what did you have to do to drop the motor on to that bike
It's not that hard, it drops in no problems just to get your spacing right with the brakes
@E-bikeguy it drop but I had to take the freewheel off for it to fit I wish I can show you
@Gene Griffin what freewheel you have? Send me a picture at theebikeguy08@gmail.com
