im having too much fun, so far i put 390 miles on my 50cc friction drive bmp kit, i gotta say this thing is too much fun and rides like a dirt bike!,it tops about 43 MPH and cops dont care about what i do or where i go LOL, its awesome, its like all my troubles are gone when im riding my bike, it so weird, its like this sense of freedom and happiness at the same time, i literally ride my bike everywhere, to the lake for fishing, to work everyday, and even across state (once). and it can handle any hill! i havent had 1 problem since i bought this thing, except one time when the pull start coil came loose, but my story wasnt always joyful, about 5 months ago i fell in an unfortunate accident on my motorized bike and i broke my wrist and had to get a titanium plate put in in, i am now fully recovered and motorbiking again, i am gonna stay way more alert and go slow around those corners. i am definantly gonna buy another kit, so i highly exremely recommend the bikemotorparts kit to anyone who wants a problem free and extremely fast bike...
