A bike acceptable for use on the track cannot have brakes and must have a fixed gear. There has to be enough clearance for a 2×4 wooden stud set on its end to fit between the bottom of the pedal and the ground when the bike is upright and the pedal is in its lowest position. The bike must have dropped handlebars. If it has quick release hubs the levers must be taped to the frame. Track bikes of various sizes are available for rental.
