Re: 50cc GY6 on a Bicycle??
I a 49cc that had a complete 80cc kit, cyl/piston, head, carb, ext, etc. It was pretty much a screamer for what it was. Whats cool as long as the sn begins with 139QMB the law thinks its 49cc. You can get a complete 150cc shipped to your door for $299. Should be a simple matter to engineer a drive off the cvts wheel shaft. They are electric and kick start and will start on an R/C lipo battery. Also have a reasonably hefty charge system too. Properly setup the cvt preforms as well as a manual trans and is much easier to deal with. It will supprt the bike as a suspension member and runs a single shock and has an excellent drumbrake, though the drum is intregral to the scooters wheel.The possibilities are wide open to creative building
