Well ok im makeing a motorized cruiser bicycle. i need a bicycle.Meet three condtions .1.My Height Of a bike,2.linebreaks/ anything besides cruiser brakes.just because i heard they dont really slow you down when your going 20 mph +....3 less then 350 bucks or a little more .the cheaper the better .im useing this by the way A 49cc 4 stroke .http://www.bicycle-engines.com/49cc-4G-T-Belt-Drive-Complete-Gas-Powered-Engine-Kit.html
Every thing I ride has down hill commercial grade triple tree sus forks because of being tall.. It is not easy.. The forks are great because they get the peddle cranks out from way behind me and I can run a good 203mm disk brake up front. The list goes on custom seat that I can ride from the tip of my butt on instead of on my man hood.lol.
It is a little like buying shoes of they don't fit in the store they will not get better later
A lot of folks are leaning to the 4 stroke kits they are definitely a league up from the H.T. motor I think sometimes? They don't have the brute power but longevity is there. Unless you wanna a 212 cc motor or something of the like?
