ABSTRACT:
A handle device for bicycles provides an adjustable rider training support point for training helpers. A handle and extension member is pivotally mounted to the rear axle and the pivoting motion conveniently places the handle proximate to the rider, avoiding the extraneous moments and forces experienced by present day fixed handles. The handle is allowed to pivot in the plane of wheel rotation, but the device is fixed in position when the optimum position is achieved. An alternate configuration limits pivoting motion to within a specific range. This allows convenient pushing, pulling and sideways support when the bicycle is at rest or being ridden. The handle is also mounted on telescoping members to conveniently adjust the handle height. The range of motion is also adjustable by a telescoping frame support or a fixture having tapered stops attached to the frame of the bicycle.
