    Should work -- why not --- yes, here we go --- in the old days the boys would throw just about any kind of engine on their paperboy racks -- and the fun was on !!! What kind of engine is that ? Looks pretty solid.. Happy Riding from - Mountainman

    If it runs as good as it looks -- clean -- would think that it's worth a shot... Let us know how this project comes along... Happy Riding from - Mountainman

    I think your concern will be, "How wide is it?" It may well interfere with the pedals. Could work with a crank forward bike. Anything is possible. It's just a matter of how to make it work.

    hi; i think that is the engine i ordered this week, if so it is a pull start 49cc for 99.00--scootercatalog.com they have a series of motors, clutches, and things that will work for our rigs.

    How is that going to fit inside a "V" frame?

    Its a gen2 48cc aircooled pocketbike motor. Usual bounting is bolts through the bottom and the flange by the clutch housing. You can get away with just using the bottom mount.

    They are wider than the happy time engines though. But quite usable.

    Oh man, that drive shaft is just screaming "hook me up to a 14 tooth sprocket and let's go!" :) ;)

    The HT has an internal gear reduction that this engine doesn't. It was designed to run a much smaller wheel than bicycle wheels, so you're gonna need a jack shaft or a gear box.

    so this might work better. i hope so or the old excuse it's just a bike might need some polishing :grin: that's cool my anniversery is coming up. :smile:

    That's moving in the right direction. With a 26" wheel, shoot for between 18 and 20 to 1 final ratio, crank to hub.

    So now what will you do about the width issue?

    Good question, 'van. Looking at that thing, depending on the frame, why can't it go high and forward? Clear of the pedal crank circle, idler/chain tensioner on the seat tube, left side drive sprocket?

    You can always go back and high, believe me it works better.

    Are you totally set on a frame mount?? Because if you wouldnt mind a rack mount, then there is instructions on how to put a pocket bike motor on a rack mount for a bike here: http://www.motoredbikes.com/showthread.php?t=7996

    Some guy has put a pocket bike engine (cag) in a frame mount though, its on here somewhere, I'll have a look for you.

    The engines are pretty high performance engines, plus there are so many performance modifications you can do to this little screamers.

    Revelstone, pb engines are bargains, compared to $275+ Robins/Hondas/Mitsus/Tanakas. Ya just have to fab the throttle and tank.
    Right now I have a stock pb and a 10hp(supposedly)pb engine awaiting a donor bike. The HP one is bolted onto a Staton gear chain drive box, awaiting a donor bike. I'll prolly get restless, and fit it to the friction drive on my cruiser bike.
    Rack mounts are much easier to install that engine, especially with Staton products.
