A zero turning radius power lawn mower for operation by a standing occupant includes first and second independently driven and controlled rear drive wheels mounted on separate drive axles. A riding platform for supporting the standing occupant or operator is located between the first and second rear drive wheels. The rear drive wheels are independently driveable in both the forward and reverse directions at variable speeds so as to allow for substantially zero radius turning of the mower about a central turning point. The riding platform is positioned near this turning point or axis so that the standing occupant remains substantially unaffected by centrifugal force created during approximate zero radius is turning of the mower thereby allowing the mower to take such turns at higher speeds. The low center of gravity created by the position of the riding platform for the standing operator also results in the mower having improved traction and being less likely to pop “wheelies” upon acceleration.

An apparatus for performing realistic motorcycle stunts while stationary includes a motorcycle, a restraint bracket, a road simulation means, a failsafe mechanism frame savers, an exhaust vent system, and safety protection. The restraint bracket comprises a bracket system for the attachment of the motorcycle to the apparatus. The road simulation means comprises an apparatus such as a 900 lb. Barrel that spins on two pivot points creating 100% balance under the rear wheel or front wheel of the motorcycle for “popping a wheelie” or performing an “endo” that can simulate actual road conditions. The failsafe mechanism frame savers comprises a series of sensors in electronic communication with the restraint bracket and road simulation means to ensure that the motorcycle does not roll over on one side or pitch back too far. The exhaust vent system comprises a tubular system in fluid communication with the motorcycle exhaust for venting exhaust gasses away from the proximity of the apparatus, the operator and any bystanders. The safety protection comprises general personal safety gear and a series of pads and nets located in areas around the apparatus to protect riders should they fall from the apparatus.

An amusement-type vehicle is provided particularly for doing so-called wheelies having a short wheel base upon a platform-type base with at least two side by side wheels forwardly and one wheel rearwardly upon which wheelies are performed and having a central handle by which the vehicle may be controlled.

The present invention relates to a human powered exercise scooter. More particularly, the invention allows a standing user to power the wheeled scooter by moving stabilized pedals with the feet along a closed loop arcuate curve to drive at least one wheel of the scooter. Further, steering, hand brake and stunt features are provided. The traditional kick scooter comprises a pair of small wheels, steering and a platform to support at least one foot. Propulsion is achieved by pushing the scooter with one foot in contact with the ground while the other foot remains on the platform. While this type scooter is popular today among youngsters, the scooter is slow as a means of transport with a bumpy ride and tends to exercise one leg differently than the other. Stunt features are provided to perform certain tricks such as wheelies, rail grinding and step maneuvers. The pedals have curved ends to accomodate the feet during the downward power stroke.

The present invention provides an apparatus and a method for using the apparatus for safely training a motorcycle rider to perform a wheelie, either while moving or while stationary. The apparatus provides a safety system which prevents the motorcycle from tipping over backwards or sideways.

A zero-turning-radius power lawn mower for operation by a standing-occupant includes first and second independently driven and controlled rear drive wheels mounted on separate drive axles. A riding platform for supporting the standing-occupant or operator is located between the first and second rear drive wheels. The rear drive wheels are independently driveable in both the forward and reverse directions at variable speeds so as to allow for substantially zero-radius-turning of the mower about a central turning point. The riding platform is positioned at this turning point so that the standing-occupant remains substantially unaffected by centrifugal force created during approximate zero-radius-turning of the mower thereby allowing the mower to take such turns at higher speeds. Such positioning of the platform also provides for improved maneuverability, reduces the likelihood that the platform will bottom out when the mower goes over bumps, and creates a safer mower less susceptible to tipping due to the resulting low center of gravity. The low center of gravity created by the position of the riding platform for the standing-operator also results in the mower having improved traction and being less likely to pop “wheelies” upon acceleration.

An improved off-road wheelchair having detachable wheelchair wheels having disc brakes, an anti-wheelie wheel and at least one detachable stability wheel.

The invention has a purpose of providing a wheelie controller and a control method thereof capable of preventing a reduction of acceleration that is more than necessary and reducing a shock during a contact of a front wheel with the ground when a wheelie state is terminated.

The wheelie controller for controlling a wheelie of a vehicle body computes a target trajectory, which is a target of a parameter and is used to control the wheelie state of the vehicle body, in accordance with the parameter that is related to pitch of the vehicle body and controls an increase/reduction of the pitch of the vehicle body so as to bring the parameter close to the target trajectory.

A toy vehicle includes a chassis, a front road wheel supported for rotation from the chassis and a rear road wheel supported for rotation from the chassis. A reversible motor is supported from the chassis and is operatively coupled with one of the front and rear road wheels so as to rotate at least one of the front and rear road wheels to propel the toy vehicle in a forward direction. A wheelie mechanism is operatively connected to the motor and has a first end pivotally attached to the central axis of one of the front and rear road wheels.

The invention relates to an element with teeth used for delivering motion, and in particular relates to a belt wheel unit. The belt wheel unit is sleeved on a belt wheel rotor shaft (2), the belt wheel unit is provided with engaging teeth (12) with equal tooth thickness which are connected through a connecting part (11) and take the axial line of the belt wheel rotor shaft (2) as a central line and are in circumferential distribution at equal intervals relative to the central line; the belt wheel unit is characterized in that the engaging teeth (12) are arranged at equal intervals, tooth crests have the same rake ratio relative to the axial line of the belt wheel rotor shaft (2), and the minimum distance between the opposite end faces of the two adjacent engaging teeth (12) is greater than the tooth thickness; and the engaging tooth (12) is composed of a connecting engaging tooth (121) connected with the belt wheel rotor shaft(2) through a tooth bottom and a drive engaging tooth (122) which does not contact the belt wheel rotor shaft(2) at equal intervals. The belt wheel unit adopting the technical scheme provided by the invention has simple structure, thereby realizing the stepless adjustment of the radius of the belt wheel.
