Hi..Newbie from Seattle. I like long walks on the beach and maybe motor bicycling. I DO NOT want a big HEAVY 49-66-80cc engine, NOR super heavy batteries. I would like to use a model airplane engine and use it for hills and industrial areas, etc.. I would like my bike to be as light as possible. Can this work, is there a thread. What else do I need besides properly mounting the r/c engine with sprocket and chain. Do I need a clutch, a trannie- or could I just slip the chain on and off the sprocket? I just want some very simple- I turn it on and ride! Thank you sirs!
