Gravity Bikes Bicycles
by: BoracayApps • 5
A gravity bicycle is a bike that allows you to go as fast as possible on a downhill course. To fully enjoy riding a gravity bike you need a road with a steep downhill grade and protective clothing in case you fall off. Gravity bikes are modified to make them as fast as possible and some can reach speeds of 60 MPH. FREE DOWNLOAD.
