Friction Drive E-Bike

myminifactory

This design is specifically tailored for bikes with limited space under the seat tube, precluding the use of traditional friction drive systems. To maintain constant friction between the motor and tire, two 1.2mm springs are employed, with adjustments made via zip ties on their opposite ends.
