I’m planning to use the Q128C to convert a 26” hard tail mountain bike which I use as for gravel riding mostly on level trails.
I’m hoping to use 48 volt system.
The variants on bms battery are 201 rpm and 328. According to my calculations, 201 rpm will top out at 15 mph ( no load rpm speed), which seems too low. The 328 rpm has a a no load speed of about 24 mph.
That seems too high, I don’t think the power band will support 20+ mph. But given the choice, that seems like a better solution.
What if I choose a 201 rpm motor 36 V and run it on 48 V? That Would did give a no load rpm of 4/3 * 201 = 268 which seems like a great compromise. Will 48V over stress the 36V motor?
Any suggestions for battery and controller?
I like the idea of BMS battery with built in controller, and the throttle etc comes with it. but they don’t tell you which controller it is.
Em3ev seems like a better battery choice, but the controller and other parts cost extra.
Thanks for any help!
