A wheel for a vehicle is provided. The wheel has a first rim support member having a first hub portion rotatably mounted on an axle, and a second rim support member having a second hub portion releasably rotatably mounted on the axle, the second rim support member being releasably secured to the first rim support member along a region spaced from the axle. A rim portion extends from at least one of the first rim support member and the second rim support member and is configured to support a tyre thereon. A flywheel is positioned between the first rim support member and the second rim support member and has a flywheel hub portion releasably rotatably mounted on the axle between the first hub portion and the second hub portion.

A wheel for a human-powered vehicle is provided. The wheel has a flywheel rotatable about a flywheel rotation axis. A flywheel drive is positioned to engage the flywheel to control rotation thereof. A control unit is coupled to the flywheel drive and configured to determine a target rotation speed for the flywheel based at least partially on user input received via an electronic user interface and motion data received from at least one sensor, and direct the flywheel drive to rotate the flywheel at the target rotation speed.

The invention relates to the field of vehicle engineering, and more particularly to gyro-stabilized two-wheeled vehicles, primarily motorcycles. A gyro-stabilizer for a two-wheeled single-track vehicle, preferably a motorcycle, is configured in the form of a gyroscope in a gimbal mount, an outer ring of which is connected by a two-way axial pivot joint to the frame of a vehicle, wherein the axis of said joint is oriented along the longitudinal axis of the vehicle; an inner ring of the gimbal mount is connected by a two-way axial pivot joint to the outer ring; and a spin axis of the gyroscope is connected by a two-way axial pivot joint to the inner ring of the gimbal mount, wherein the axes of all three pivot joints are mutually perpendicular, and wherein the gyro-stabilizer has a means for locking rotation of the outer ring about the axis of the pivot joint between said outer ring and the frame of the vehicle. According to the invention, the gyro-stabilizer is disposed on the swingarm of the rear wheel and has a means for locking rotation of the inner ring about the axis of the pivot joint between said inner ring and the outer ring, wherein each locking means is in the form of a servomotor which allows the forced rotation of the corresponding ring in response to a command from a microcontroller controlling at least the speed and the permissible bank angles of the vehicle, and an additional weight is secured on the axis of the pivot joint between the inner ring and the spin axis.

A balance bike conversion system may include first and second protective inserts, each having an interface adapted to engage opposite ends of a bicycle bottom bracket. A connector may be adapted to connect the first and second protective inserts, and may be adapted to adjust the distance between the inserts, thereby accommodating variability in the width of the bottom bracket. The system may further include adapters to enable the system to be used with bicycles having bottom brackets with different diameters, and may use an elastomeric gasket to accommodate larger bottom brackets. The protective inserts and/or adapters may provide mechanical support to the bottom bracket, thereby protecting it from damage.

A telescoping carer's handle for a child's kick scooter comprising a padded handle on one end of a telescoping pole mechanism. The telescoping pole mechanism is arranged parallel to and attaches to the vertical portion of the child kick scooter's T-bar handlebar by means of one or more clamps and brackets. The telescoping carer's handle is reversibly extendable and retractable from the scooter in a direction substantially upwards and downwards, respectively, relative to the handlebar portion of the scooter. There can be a locking mechanism between adjacent telescoping tubes that allows the user to raise or lower the top of the pole and then lock it into position so that, in use, a carer located adjacent to the scooter can grasp the handle at a comfortable height and safely steer, stop and or propel the scooter and child, and alternatively retract the carer's handle when not in use.
