An auxiliary power device of a bicycle includes a driving member and a base member provided at a first section and a second section of the bicycle respectively. The first section and the second section are two parts of the bicycle, which has a relative motion therebetween in cycling. An input member is provided to the base member to be driven by the driving member when the first section moves relative to the second section. The input member turns a power storage member to store a power. A control member is provided for manipulation to release the power stored in the power storage member for moving the bicycle forward.

A bicycle driving assistance device includes a crank having two pedals and a first chainwheel unit is connected to the crank and a gear box which has its input shaft connected to a first chainwheel unit. A one-direction bearing is connected to the input shaft so as to rotate in the direction to store energy. A vortex spring is connected between the input shaft and the case to which a first gear of the gear box is connected. An output shaft of the gear box outputs the energy to the rear chainwheel unit via the second chainwheel unit to move the rear wheel of the bicycle. The rear chainwheel unit and the crank are separated by a one-direction bearing. When the force applied to the pedals is less than the energy stored in the vortex spring, the energy is released to assist the rider to move the bicycle.

A clutch mechanism may be positioned in engagement with a slave sprocket of a drive train and a hub of a flywheel to create a frictional engagement between the sprocket and the hub, and to establish a break-free force threshold. When the drive train is actuated in the forward direction, the slave sprocket and the hub may move together, and when the drive train is actuated in the rearward direction under the influence of a force greater than the break-free force threshold, the clutch mechanism may slip between the slave sprocket and the hub, allowing the slave sprocket and the flywheel to move independently of one another. The clutch mechanism may also include a spring tensioner whereby the break-free force may be adjusted.

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. 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 bicycle, ensuring that the rider can “steer-out-of” an unintended tilt or bank. Likewise, the gyroscopic effect limits the rider's ability to execute excessive steering, thereby preventing jackknife movements.

An exercise bicycle including a frame having a seat and handlebars, a high-inertia flywheel having a hub at a center of rotation, the flywheel being rotatably supported on the frame at the hub, and a drive train including a drive sprocket, a crank arm attached to and extending from the drive sprocket, and a pedal attached to the crank arm, the drive train being rotatably supported by the frame. The drive train also includes a slave sprocket fixed to the flywheel at the hub, with the drive and slave sprockets connected in a direct-drive relationship, the drive train driveable in a forward and rearward directions to cause the flywheel to rotate. A clutch mechanism is positioned in engagement with the slave sprocket and the hub to create a frictional engagement between the sprocket and the hub, and to establish a break-free force threshold. When the drive train is actuated in the forward direction, the slave sprocket and the hub move together, and when the drive train is actuated in the rearward direction under the influence of a force greater than the break-free force threshold, the clutch mechanism slips between the slave sprocket and the hub, allowing the slave sprocket and the flywheel to move independently of one another.

A flywheel energy storage system includes a driving wheel rotatable relative to a first axis; an electric motor for driving the driving wheel; an electric generator; a driven wheel adapted to drive the electric generator; a flywheel rotatable relative to a second axis parallel to the first axis; a clutch assembly for engagement or disengagement of the flywheel and the driven wheel; and a transmission gear train assembly engagingly interposed between the flywheel and the driving wheel adapted for conveying kinetic energy from the driving wheel to the flywheel. The transmission gear assembly is provided for allowing the flywheel driven by a low-powered electric motor to drive a high-powered electric generator.
