I am in the prosess of ordering av Frey ebike.But a lot of reading makes my hesitate.Many reviews say the motor is lazy and overheats easily.And many reviews says the opposite.So which is it?
I already have a bafang bbs 36w 500w 25a and it needs to be significantly stronger than my Bafang bbs if it should be interesting.
I have stuidied all the info I can find,the thing that worry me a bit is the "low" gear reduction 1:18 is not much.My yamaha pw-x Haibike have 1:45 gear reduction.
I see the Bafng Ultra has good amount of coppar and a big rotor .But from playing with the ebike.ca simulator it seems that bigger gear reduction is much more important for torque and overheating than a bigger motor.
