Each end of the axle of the front wheel of a bicycle is connected with a pivot to a support arm. These two support arms are substantially parallel to each other and substantially extend from the front wheel axle area to a distance behind the front wheel. Behind the front wheel, a cross bar connects the support arms together utilizing pivots in the connections. Behind the first cross bar, a second cross bar connects the support arms together utilizing pivots in the connections. The center of both of these cross bars is connected to the frame of the bicycle through a pivot. The two cross bars and the axle of the front wheel are substantially parallel to each other. The axial axis of the pivots are all substantially parallel to each other, with the axial axis of the pivots being reclined nominally 20 degrees in the rearward direction from vertical. The pivots used in the connections permit the angle to vary between a support arm and the axle of the front wheel. Linkages connected to one of the support arms permit the bicycle operator to hold steady or move the support arm relative to the pivots in the center of the cross bars. When the bicycle rider thereby moves the side member, the angle between the wheel and the bicycle frame members changes, and thereby steering of the bicycle is achieved.
