both segway and bicycles are designed to carry one rider. however, segway riders do not sit on a seat. instead, they stand on a platform while they are riding. the platform is the floor of a strong metal framework. a post with handles for the rider to hold is attached to the front of the platform. a wide rubber wheel is attached to each side of the platform. except for these two wheels, there are no mechanical parts on a segway. like a bicycle, it has no engine. however, unlike a bicycle, a segway has no brakes, no pedals, no gears, and no steering mechanism.
