A side by side bicycle has a frame including rear forks, a transverse crank tube, an upright seat tube and an upright steering tube. A rear wheel is mounted in the rear forks, and a crankshaft is journalled in the crank tube. There is a first pair of cranked pedals on one end of the crankshaft on one side of the frame and a second pair of cranked pedals on the other end of the crankshaft on the other side of the frame. A chain and sprocket mechanism connects the crankshaft to the rear wheel. A steering spindle is journalled in the steering tube, and front forks are secured to the steering spindle and carry a front wheel. From the steering tube a duplex yoke has yoke bars that extend laterally at a variable orientation. At one end of one yoke bar there is a handle bar tube from which a handle bar post projects upwardly to carry a first set of handle bars. The other yoke bar at its opposite end carries a steering head with a steering sleeve rotatably mounted in it. A steering post extends upwardly and is axially and rotatably movable in the steering sleeve, being clamped in a selected position. A second set of handle bars is on the steering post, at the bottom of which there is a chain interconnecting the steering sleeve and the steering spindle, the chain runs passing on opposite sides of the adjacent yoke bar.
