Abstract: The present invention provides a light emitting wheel, characterized in that, a light emitting device is attached to the light emitting wheel, the light emitting device is composed of a bulb, a first elastomer, a second elastomer, a power supply, a conducting wire and a protective cover. When a vehicle is started, the on-off state of the bulb can be controlled by a switch, the bulb will move towards a direction away from the center of the wheel hub, and a ring of light will be formed due to the phenomenon of persistence of vision. The higher the speed of the vehicle is, the larger the diameter of the ring of light is, so that the vehicle is driven with rich dynamic effect.

Abstract: A bicycle simulator (1) is basically constituted by a bicycle pre-arranged for static or pseudo-static use. The bicycle comprises front and rear supports (13, 14) for resting on the floor (12) that simulate the contact of the wheels of a normal bicycle on the road. The two supports are preferably constituted by a front supporting wheel (13) and by a rear supporting wheel (14) that rest on the floor and support in a freely rotatable way the respective wheel axles (3, 11). Rotatably mounted within at least the front supporting wheel is a flywheel (F1, F2). The front flywheel (F1) is set in rotation by a respective electric motor (M) or by a transmission driven by the pedals, for creating a stabilizing gyroscopic effect, which enables the user to maintain his balance when pedaling with the bicycle stationary, resting on the floor via the supporting wheels in a static condition.

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.

Abstract: A wheel, such as a traction wheel, with a momentum enhancing apparatus.

The momentum enhancing apparatus may include one or more bodies that either translate radially between the hub and the rim of the wheel to change the mass moment of inertia of the wheel, or rotate with the wheel and transfer the momentum of the bodies to the wheel under increasing loads. Methods of using such apparati and vehicles equipped with such apparati are also enclosed.

The linkage mechanism has an X shape configuration to allow the foot platform to move from higher to lower positions. The driving mechanism transforms the downward movement of the foot platform, caused by the weight of the user, to rotational movement, and then stores it in a spring that drives the front wheel. The foot platform can be tilted backward to brake the back wheel. The transport device is powered by the repeated vertical movement of the user's feet.

Abstract: An exercise cycle includes a base frame having front and rear wheels and a seat slidably mounted thereon. A pair of pivotal foot pedals operate a steering mechanism to turn the front wheels toward the left or right. Between the foot pedals is a vertical support bar having a drive pawl at an upper end with a cable spirally wrapped thereabout. A handle affixed to the distal end of the cable is accessible by a rider resting in the seat. A drive chain encompasses a gear on a side of the pawl and a similar gear on the rear wheel axle. Accordingly, a rider sits on the seat, grasps the handle and places the feet on the foot pedals. By pushing with the legs and simultaneously pulling the cable, the rider propels the cycle while simulating the workout typically provided by a rowing machine.

Abstract: A wheel hub for capturing energy created by road bumps and converting that into energy to be used in moving a vehicle in it's current direction of motion. Energy return is accomplished by elastic spring means, although the physical principle of operation is not directly obvious. Any road shock imparted upon the wheel will result in a radial displacement of an outer wheel hub and thus a radial force toward the center of the wheel. The radial force will be released as an axial rotation imparted upon a wheel hub assembly, thus increasing the axial speed in the current direction of motion. The principle is similar to that causing the earth to rotate around the sun. The wheel hub assembly will not wobble erratically since there is a dampening component by virtue of a vehicles weight and moment of inertia of a rotating wheel. Additionally, total shock absorbtion, is increased.

Abstract: This invention provides a stabilizing system and method for two-wheeled vehicles (typically small, human-powered bicycles) 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.

Abstract: A flywheel power unit that can be inserted into a variety of machines. The standardization of the power unit means that the more expensive gearing, clutch and flywheel components do not have to be duplicated in each human powered machine. Standard bicycle gearing components can be assembled with a modified clutch for a typical motorcycle to create an inexpensive human powered flywheel power unit. As the user pedals, power is stored in the flywheel. The flywheel axle is connected to a transmission transfer gear that turns a transmission input gear for a transmission with multiple gears in a gearing ratio of 10:1 to 0.8:1 (which is typical for a motorcycle transmission.). A transmission input gear and the transmission transfer gear are approximately a 1:1 gearing ratio. A transmission output gear is attached to the transmission that provides power output from the flywheel only when a clutch within the transmission in engaged.

A flywheel is mounted for rotation on the frame. One-way drive connections between the reciprocating pedal and the flywheel and between the flywheel and the rear ground wheel are provided. Downward pivotal movement of the reciprocating pedal by application of the user's foot to the foot engaging surface causes rotation of the flywheel in a drive direction, which in turn causes rotation of the rear ground wheel in the drive direction. Upward pivotal return movement of the reciprocating pedal is possible without preventing continued rotation of the flywheel and the rear ground wheels in the drive direction.

Abstract: A sprag wheel is a one-wheeled recreational vehicle. Two treads extending on opposite sides of a ground wheel provide a place for the rider to stand. A flywheel concentrically mounted with the treads and ground wheel and housed within the ground wheel provides pitch stability for the rider. That is, the flywheel is coupled to the treads and ground wheel so that the flywheel rotates faster than the ground wheel. The treads are coupled to the flywheel so that the treads will move only by changing the rpm of the flywheel. Thus, a relatively large force is required to move the treads, and, in any event, a force greater than that necessary for the rider to balance on the treads. The sprag wheel of this invention is designed to imitate Thor's wheel in the "B.C." comic strip, so the ground wheel has a relatively large diameter and a moderate width so that a rider may balance on the wheel.

Abstract: Autorotation in helicopters at low altitudes can be achieved even when the inherent design of the helicopter would prohibit successful entry into the autorotation mode. Angular kinetic energy from the main propulsion engine is stored in a flywheel which automatically transfers this energy to the main drive shaft in the event of engine failure. During normal operation, the flywheel is driven through the main drive shaft by coupling to a secondary drive shaft. The main drive shaft in turn is driven by the engine through an overrunning clutch assembly. The flywheel is maintained within an evacuated housing whereby air drag is substantially eliminated. In the event of engine failure, the overrunning clutch disengages the engine from the main drive shaft and flywheel will continue to apply energy to the main drive shaft through the secondary drive shaft to permit autorotation and a no-damage landing even at low altitude flight levels.
