    hello :eek:

    im in the process of building my bike as i post :)

    im using a gsr40 goped to make a friction drive bike im cutting the rear of the goped off and making the gopeds tire turn the rear tire...

    If i am not confused this should make my bike go the same speed as the goped it will be a little slow maybe 30mph tops, but i dont have to pedal and its legal YAY!

    this is going onto a 26" tire trek superlight aluminum mountain bike frame so it is all going to be bolted on not welded

    Welcome to the forum!!

    Yes, in theory, if you just put the gopeds tire onto the bike tire, the bike should go exactly the same speed as the goped would. It probably won't go quite as fast since there will be more friction as theres more wheels and more weight probably.

    also, make sure you have the goped engine oriented the correct direction. I could see myself installing it wrong and having the bike only go backwards!

    Cant wait for pics!

    Thanks for the warm welcome .. : )
    I am hopeing to get to the shop today and start fabbing the mounts for the setup hopefully after that it should be pretty straightforward i have it drawn out, chosen the materials already and bolt locations so this should go quickly i hope.

    as it is so cold out and the forecast says bad weather for a while,even if i do get it all done today the roads are all icy dang weather 8 ( long test ride just wont be possible for a few days

    sounds like the weather here....started with freezing rain, now the roads are white with sleet. supposed to keep doing this for another day...or so.
    no riding here either :x

    good luck on your fabricating!

    heres a mspaint drawing of my design plans

    and a pic of what the goped looks like im cuttin the goped right where the frame goes under the deck (in the rear of course ) and modding it from there to fit this setup

    Looks good. I wonder if you could use the disc brakes on your bike as well.

    yeah i was thinking of how i could accomplish swapping the disks to the bike.. looks to be sort of troublesome though but im sure it can be done.. that will be a project i will probably go after once i get the engine setup and tested ect..
    i have also found a larger front sprocket for the goped engine it should increase the top speed to 47 mph or so if the 2.5 horse has the guts for that speed anyway.

    ok well its built it does around 45mph i designed it differently than in the pictures i will post pictures of the final design sometime soon.
