  1. I would love a few more technical details like control, gears, motor etc. This method has been used before but yours is definitely the best.

  2. Maybe this is a stupid question but how does the mechanism works that pushes the motor against the tire when he uses the throttle button?
    In his instructions I found the information that a spring pulls the motor away from the wheel but I spent a long time trying to figure out how the motor is pushed to the tire again. I hope someone could help me with this out.
    Thanks in advance!
