I have recently buy a fonding ebike with standar bafang 250W rear hub, with batery inside frame (sanyo 36V 10.4Ah distributed in 40 cells 10x4 with a 10s4p config)
This is a chinnese, cheap and fine design with tipical low cost but nice accesories (freewheel shimano megarange 7 speeds 14-34T, disk brakes, double suspensions, magnesium wheels, ...).
I can reach 30-31Km/h on flat with vewy low assisted, and I would like to increase top speed up to 35-40 Km/h and I dont know how to make it with minimun changes.
I have read that motor limit the speed by their RPMs, and I suppose its about 315RPMs.
I have read that best is to change to 48V, but its supposed very dificult for me. Do you know how increase the RPM overvolting?
The battery is a 10s4p inside frame so its very dificult to get 13s4p, and I dont know I I have to change controller or motor. Motor seems to support 48V, but I dont know nothing about controller.
I was thinking in get a 11S-4p (40V), but I dont know If I have to change (o re-program controller)
Do you know if there another options to get more max-speed with this configuration?
At first time I want to change the shimano 14-34T for a very difficult to find 11-32T 7 speed freewheel, but this only increase speed dowhill.
Thanks for the advices.
