Hello from Washington State

[CamaroMan79]

Im new to the site and just introducing myself. Im trying to build a 20" bike with a 49cc pocket bike motor on it, but am having trouble figuring out how to run a gear on the rear tire. If anyone can help me out or have pictures of there 20" setup please let me know.

Hi Camaro, Can't help about a gear in the back. All I have ever seen is sprockets. I used a rag joint from a china kit, there are much better sprocket adapters from Manic mechanic though.

Hi CamaroMan79, Welcome to the forum, glad you joined us.

Check out the DIY Home Built Motorized Bicycle (non kit) - Bicycle Motor at Motorized Bicycle Forum there is some great builds in there that may help you out.
