A velocipede having a single driving wheel which is powered by rotating pedals that rotate a sprocket that is connected to the driving wheels by a chain. A roller assembly comprises small diameter rollers having a roller axis that is disposed lower than and in front of the pedal axis. The rollers are connected to the velocipede frame by a bearing member so that the rollers can be articulated allowing the rider to lean on the velocipede thereby controlling the direction of movement.
