    The first bike is a GoPed 23cc friction engine that is clutch by the parking brake i install on the frame, is a good bike but kind slow and when it rains i cant use it due to the slippage of the drive on the tire, the second one is the last one i build and it have an 80cc ported engine and the sick bike transmission, that one is very fast, yet to check the max mph...

    Welcome, and sweet rides, bro! Heck, with those fat tires, it almost looks like those bikes don't even need suspension.

    Cool builds!
    Doing fat tire bikes is double tough, well done.

    So are shifters.

    Thanks guys, yes is not that easy to install the engines on those fat tire bikes at first i have to think a lot of how to install the engine with out touching the tire with the chain... now that i seen all the mods that you guys are making on your bikes I feel like is more to be done, my next build will going to be a dyno with a 212 predator, i know is being done before but I will try to make it unique and fast...

    Naw, you just choice the wrong way to motorize it is all.
    I put a 1KW electric shifting system on the one I did.

    Hey, to each his own I guess, but I think a 212cc engine on a bicycle is about as silly an idea as...
    never mind...
    Have fun and try to stay alive.

    You don't necessarily need more power for more speed, gears work good ;-}

    They are the same thing.
    You use the shift kit to move your power output to the right side and use the bicycles gears.

    Doubtful bicycle parts will handle a 212cc engine.

    If you want to put motorcycle power on something, put it on a motorcycle frame.... with pedals to stay kinda-legal ;-}

    That was just an 86cc 4-stroke semi-auto 4-speed engine and it was a rocket.

    The point is, all the parts are deigned for motorcycle engines and their power, most bicycles are not.

    That MotoPed frame is rated for 250cc if memory serves, but a moot point, your engine wouldn't fit it and it was ~$2500 delivered completely disassembled.

    If you are bound and determined to use that engine please put it in a sturdy bikes with great brakes.
