    DIY Wide Crank

    I looked around for just one side of the wide cranksets to clear my pull start, and found 1 result at mbrebel. It was reviewed on this site, on another thread as being made "dirt cheap". The price was 28 dollars plus 8 for shipping and, that was too high for a piece of metal, so I made my own. I...

    Are there any other 66cc/80cc engines out there or better?

    I'm new to the forum and wish to build a motorized bicycle. I plan on building the 66cc one first, but I have bigger ambitions after that. I looked at a Kohler's SH265 and SH255, I am wondering if it is possible to mount these engines. They have more power, and most importantly, have better...

    Best motor out there?

    Parts jamming break lines

    So I see a lot of projects done on bikes with the break lines going under the top tube. Mine are on the top and when I bolt my fuel tank on, it presses on the cables and screws up my breaks and my gear shifter. Anything I can do?
