I have a hyper bicycles beach cruiser with a 2 stroke 66 cc engine. I'm using the hub mounted cnc style 40 tooth sprocket.
Recently the bike petals began to turn while walking. The petals also try to turn while coasting though you can stop them you can feel them working against your feet while the engine is engaged. The bike also doesn't roll backwards without coming to a stiff point and stopping before a ping. The chains and sprockets seem fine and aren't skipping.
The bike seems to roll forward OK but when rolling forward using the engine the bike makes a few popping noises as the petals rock back and forth controlably. speed doesn't change it?
The brakes seem to work fine.
Not sure what else to look into?
Anyone have any experience with this?
