    hello,

    i am planning on putting a motor on a beach cruiser but most of the cruisers i am looking at have only coaster brakes. i seem to have read that you cannot put a small motor on a bike with coaster brakes in that the rear sprocket that comes with the motor kits will not fit. how can i adapt my coaster brake bike rear axle to accept a chain? what is available out there and what vendors sell such adaptors? could i simple machine out the hole in the center of the sprocket that comes with the kit to make it work?

    thanks for any advice,

    dave

    The rear sprocket will fit. You will probably need to remove the coaster brake arm to put the sprocket on, you'll probably need to bend the coaster brake arm to clear the sprocket bolts, and you might have to modify the hub dust cap or grind the center of the sprocket out to get the sprocket to fit over the dust cap.

    i'm pretty sure most of the bikes being built use a coaster brake. all mine are, too.

    use the search feature above and you'll find tons of solutions to any problems.

    if you come across something you can't figure out when you start installing everything, just post a new thread and we'll help you out.
