This is the 4th 1speed mtb that ive built. I removed all gears and replaced with 16t bmx freewheel. 44t/16t gear ratio. Nice alum stem with bmx style handlebars that has a crossbar. I can bunnyhop on this thing over a foot. less shit to break and just as fast as a geared bike. This style bike is for retired bmxers to enjoy themselfs like they teenager again. plus if it gets stolen. who cares. at least the bike thief gets an awesome bike.
