<p>The present invention relates to a bicycle which has at least one front wheel, a pair of back wheel, and a pedal unit for transmitting power to the pair of back wheels. The bicycle comprises a first connecting shaft whose one end is connected one of the pair of back wheels and whose the other end is connected to the other of the pair of back wheels in order to support the pair of back wheels to a main frame with one shaft to be able to rotate; and a first latchet unit which supplies power transmitted from the pedal unit to one back wheel while prevents the power from transmitting to the other back wheel. During cornering of the back wheels, the bicycle can perform cornering driving by the power applied to one back wheel and can prevent breaking due to a difference in the rotating radiuses of the pair of back wheels by preventing the supply of the power to the other back wheel.</p> |
