    Motorized bicycles

    Who's made their own? I just got a 4 stroke Honda gx25. Still looking for a cruiser for sale

    I made one in the spring. 80cc 2 stroke. Lots of fun!
    Perhaps now that I have time I'll weld up a jackshaft so I can run through the bike's gears instead of just the one 38 tooth one on the other side of the cassette

                I might build a friction roller out of it, maybe on a bmw bike ;)


                I'm getting an 80cc 2 stroke soon.

                  any time i see one of these i wanna say "cool" but my impulse is to punch them for doing 30+ in the bicycle lane. If you wanna sound like a weed wacker while riding to class have at it, but when someone knocks you out; I'm on their side.

                    Just a warning, in California you have to have an M2 license, register the bike with the DMV, and have insurance. I know cause I'm dealing with the aftermath of that. No 49cc law in California anymore.
                    Drive it hard. Maintain it well.

                              When did this happen? I purchased a '78 vespa last year and it is under 50cc so they told me it was an $18 dollar one time registration and neither insurance nor motorcycle license required.
