Motorized Bicycle Trouble ShootingUse this area to post problems that may arise that you could use some help in figuring out what is wrong with their bicycle motor and what needs to be done to achieve top performance.
What size is the ball Bering that goes behind the pin that the clutch arm pushes into the motor? I lost mine somehow and I don't where it is or what size and where to go and how to get a new one.
