Abstract: To reliably prevent re-lifting of a rear wheel immediately after landing of the rear wheel. When it is determined that output of a detection signal corresponding to detection of lifting of a rear wheel has ended (S102), brake pressure—and specifically a pressure increase gradient of a wheel cylinder pressure of a front wheel—is reduced, and the pressure increase gradient that has been reduced is maintained until it is determined that vehicle body deceleration has fallen below a predetermined value K1 (S108, S110), whereby re-lifting of the rear wheel caused by an increase in brake pressure at a high pressure increase gradient after landing of the rear wheel can be reliably prevented.

Abstract: This invention is a side wheel attachment for removably attaching an auxiliary side wheel to a bicycle. The side wheel attachment comprises a single structural rod which is folded in the desired shape, i.e. forms a helical torsion spring. In natural unbiased condition, the first and second ends of the spring rod extend generally perpendicularly to one another.

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.

Telescoping legs are placable into the sides and rear of the base in an outrigged fashion and are capable of extension out from and retraction into the base. The forward legs are adjustable and, when extended provide sufficient tilt toward the rear outrigged legs so as to raise the main wheels of the wheelchair off the ground. Once the wheelchair is rigged with the legs, and the forward legs adjustably extended, it becomes practically impossible for an unattended occupant to tip over the chair. When not in use, the legs may be stowed in the rear portion of the adjustable base.
