I know it was a while back now but if possible would you mind sharing what you used to get yours battery wired to the controller I would appreciate the feedback.

[@aidanschaefer4846]

Nice bike man! So, I have a question since I'm building one similar to yours. Would it be po0ssible to use a different Lipo because I can't seem to find one with that amount of MAH, and might you have any suggestions on which lipo I could use instead of the one in the video. (I'm only looking for about 25-30 Ish MPH with my build though). Thank you!

[@AllThingsElectric_]

Yes you can most def use different lipos. I used some 8ah 6s LiPos with a scooter build I did. The mah rating won't change the speed you get out of the bike, that has to do with voltage. These 20Ah batteries get me about 20-30 miles of range.

[@yannmassard3970]

mmm considering the power, the frame, the wheels, and the chain, I would go for a larger gear at the motor, less torque, less speed but better acceleration control and less dangerous to drive.

[@AllThingsElectric_]

Larger motor sprocket wild equate to higher top speed. I messed with the gearing in newer vids. Check it out if you’d like!

[@yannmassard3970]

@@AllThingsElectric_ with this kind of motor, you will lose torque, and speed. If you porgram the motor to be in "speed control", rather than "current control", maintaining speed will get the coils to melt. But i ll check the video sure :) keep up the good work

I changed the sprocket and got much higher top speed. The motor gets hotter because it’s working harder to provide high torque, yes, but the math of gearing stands true.

[@AllThingsElectric_]

[@JAEkebruh]

Three questions if you don’t mind... Have you had any issues with the chain and flywheel on this amount of power? I’ve heard some people say the flywheels snap from the torque and had to get them welded. I’ve also snapped the chain twice on my bike (before I upgraded to a 25H chain) and completely destroyed the chain tensioner from the increased speed. (My mx500 is currently running 60v 2Kw with 3.6Kw peak (60v x 60a), yours is running a 72v 3Kw with a 9.36Kw peak (72v x 130a)) Any reason you didn’t go for a sine wave controller like the kls-s controllers? From what I understand sine wave controllers are supposed to be quieter with a smoother throttle response (but more expensive) On the other hand though, I’d assume most of the sine wave benefits are negligible with a mid drive setup where the chain is responsible for most of the noise How’s the motor temp while riding? My motor tends to get too hot to touch after about 20 mins of fast riding, but I’m running SLA’s with bad voltage sag which heats it up faster

[@trahar6257]

I’m in the process using the same motor/controller as this guy and I’m sure I’m going to need a similar 25H setup if you want to share what parts you have on your bike

[@JAEkebruh]

@@trahar6257 25h chains fit 25 sprockets so it’s a direct replacement. The 25h chains are only supposed to have a higher strength rating and I haven’t had a problem since

[@AllThingsElectric_]

Yes, the stock flywheel is weak, and should probably be replaced firstly. There’s a guy on here named Tim A. And he has a video about a solid upgrade. I wouldn’t weld it because I like the smooth coasting. I haven’t had issues yet though. As for the sinewave controller, it’s better for hub motors, so it really doesn’t make that big of a difference with this mid drive setup (like you said, most noise comes from chain and tensioner). Motor temp does go up, but honestly nothing to worry about. You could drill out the preexisting holes in the motor to a larger diameter to increase air flow, but it’s not terrible.

[@JAEkebruh]

@@AllThingsElectric_ I looked at the flywheel upgrade, def gonna do that if my flywheel snaps. For now I'll just leave it as is cause I also do like the coasting without spinning the motor. I also read on endless sphere that it's suggested to put a rubber tube over the bearings of the chain tensioner to make it quieter which could be something to look into (I'd have to find that thread again though to see exactly what it was). Thanks for the info though, I'm considering doing an upgrade like this but with either li-ion or lifepo4 (cause I don't have the balls to make the jump to lipos yet haha)
