    Hello, I'm a young person learning about bicycle mechs for my '80s Raleigh. Anyway i was wondering if there was a way to add a sprocket to my cassette that wouldn't turn my pedals if it were turned by a motor.

    are you talking about having the main bicycle chain turning the motor?

    Not that I'm aware of, however, Staton offers a rear hub threaded to accept the standard freewheel in the right side and a single 16 tooth freewheel on the left side. You can purchase a freewheel that mounts to the bottom bracket axle, allowing power to be applied through the pedal chain.

    All of the casette gears are held together by the free wheel on the hub - there is only a single freewheel unfortunatly.

    You could use a freewheeling crank though (as per SBP shifter kit or cyclone electric system)

    That's right. With a standard freewheel, if one sprocket turns, they all turn and will, in turn, turn the front crank unless a front freewheel is used.

    There's always friction for probably the simplest installation.
