This bike can reach speeds of 90mph could be even faster.

Bicycles are used typically use BMX bikes are stripped and then reverse the frame 180 degrees, the pole saddle off and welded into a new position slightly to the back and quite low because it does not use pads or crank then mounted footrests while dropdown handlebar lowered into position.
