Abstract: An architecture is presented that provides a double hinged tow hitch. The tow hitch is attached to a tow vehicle and allows full traction to the ground and complete control of steering. The tow hitch comprises two hinges secured together by a pin positioned at an upper portion of the hinges and a pin positioned at a lower portion of the hinges. The pins secure the hinges together and allow the hinges to flex in two positions. Additionally, the tow hitch comprises springs positioned on either side of the hinges and rubber positioned between the hinges to act as a shock absorber. When pressure is applied to the tow hitch, the springs will collapse into either the upper or lower portions of the hinges, causing the hinges to flex in two positions and pressing against the rubber between the hinges, thus acting as a suspension system for the tow hitch.

Abstract: This invention provides a stabilizing system and method for two-wheeled vehicles that affords the rider no restriction on the full range of movements (banks, leans, etc.) common to bicycles, but that provides greater stability during turns and other maneuvers so that an unintentional bank or tilt (potentially causing a fall) is less likely, even at relatively slow speeds and startup. A rotating mass of predetermined mass-value and radial mass-distribution is provided coaxially with the front axle. The mass is supported on bearings so as to freewheel with respect to the rotation of the front wheel. As such it can be induced to spin significantly faster than the front wheel thereby generating a gyroscopic effect at the front wheel about the axle. This gyroscopic effect influences the steering of the wheel by the rider. Due to precession, the wheel tends to follow any excessive bank by the vehicle, ensuring that the rider can “steer-out-of” an unintended tilt or bank.
