WARNING..LOUD MOTOR, SO TURN IT UP. I went out for a little night ride last night with the fat tire motor bicycle. Sounds pretty good. Put new piston, rings, cylinder, head and sealed with some gasket maker. Love these little motors and even more fun to build. working on a 2nd backup motor for camping. #motorizedbicycles #motorizedbike #motorbikes #80cc #66cc #fattirebike #fattire #fattirebikes #bicyclemotocross #bicyclemotor #bicycle #oregon #motorizedbicycle #custombicycle
