    i'm new to this forum and to the whole idea of motorized bikes.
    I have this MTB

    I wanted to fit the 80cc motor kit, but it is obvious that it doesn't fit.
    correct me if i'm wrong!
    any ideas?
    what are my options?
    thanx in advance

    It's true. You'll never get an internal combustion engine in that frame.

    There are electric motors available where the motor itself is built into the wheel hub. That could fit. They're fairly popular. But they do have drawbacks.

    You could also sell that bike and use the money to buy one with a more traditional frame. Then you could mount an 80 cc, 2 cycle engine.

    There are electric shift kits you could use also that can mount in front of the crank. KC has done that kind of set up on a few electric bikes.

    Send pictures of your bike to David Staton and he could probably design you a rear rack. It would have to attach to the seat seat stays. Of courses that means your engine will be moving around. Other than that you could get solid forks and do a front friction drive setup. No real good options using gas. The biggest with an electric is where to put the battery.

    Agreed. You need to go rack mount engine or electric with that backbone frame. If you go electric, some LiPo batteriest could be hung from the top tube. SLA bricks would have to go on the rear rack.

    The only thing else you could do is attach a pusher.

    It's a shame that no one manufactures a replica GT LTS frame anymore.

    That setup was perfect for a motorised application with rear suspension:

    Hey Fabian, that frame is nice but the engine would need the Sickbike shift kit for sure.

    But you wouldn't think of motorising a bicycle with anything less than a SickbikeParts shift kit and disk brakes.

    That's what I would do, sell or trade that bike for something more motor friendly.

    Soft tails (rear shock) bikes can be motorized but seldom direct drive, you have chain length issues as the back wheel goes up and down.
    A jackshaft fixes this by using the pedal side drive which is designed to keep chain length the same as the back wheel moves.

    They can be done, you just want to use a bike with a rear shock behind the seat post.


    Electric is nice too, they naturally hook to the pedal drive.


    If you don't particularly care about a rear shock you have way more options.
