Bicycle Roller Derby
Bicycle Roller Derby based on the Wide World of Sports TV competitions. The dials are driven by concealed N20 motors that are wired in parallel with the N20 motors driving the corresponding bicycle. Each set of motors is controlled (covertly) by hidden PWM controllers. The dials can be reset easily as the hands are driven via pulley belts. Youtube video >> https://youtu.be/jJMyNPzAyJk
