Question :
peacock groove is building me a front load (bakfiets) fat tire cargo bike. i'm interested in using a stokemonkey and i'm wondering if we can use a larger cog on the motor to increas top speed and torque? thanks?
Increasing motor cog size will decrease torque and increase the speed at which the motor wants to spin the cranks. But changing gear ratios adds nothing to power. If you want more power (=speed*torque) then you need higher voltage and/or amperage, adjusting the motor-crank gearing such that you can still pedal along comfortably. In terms of what specific parts will do what you want, please confer with Stokemonkey's manufacturer who is most up to speed:
