This disclosure relates to a system for balancing a bicycle. The system can comprise a frame, a tension system, and a steering system. The frame can be capable of mounting to a bicycle. The tension system can be capable of connecting with handlebars of the bicycle. The steering system can be mounted to the frame, further the steering system can be in communication with the tension system such that manually maneuvering the steering system can adjust tension within the tension system to steer the bicycle.

A system for automatically correcting bicycle handlebar and warehousing the bicycle includes a bicycle and a warehouse box for storing the bicycle. The bicycle includes a bicycle frame, a handlebar, a stem, a front wheel and a rear wheel; an encoder is mounted on a bicycle frame for recording a rotation angle of a stem and sensing whether the handlebar is corrected. A rear-wheel correcting and fine-adjusting device is provided in the warehousing box or on the bicycle frame. The rear-wheel correcting and fine-adjusting device automatically twists a rear wheel according to a deviation angle record of the encoder on the bicycle frame so that the rear wheel and a front wheel form a plane. The system is capable of automatically correcting the handlebar and warehousing the bicycle, thereby facilitating the automatic storage and greatly reducing the storage space in the warehousing box.

Disclosed is a truck comprising a hanger having a first pivot support and a second pivot support and an axis of rotation passing through the first pivot support and the second pivot support, a base having a structure providing the first pivot support, a pivot arm attached to the base providing the second pivot support, a pivot bushing passing through an aperture of the base, a kingpin passing through the pivot bushing, the base, and the hanger, and a locknut arranged at an end of the kingpin. In at least one example embodiment the first and second pivot support structures prevent an axis of rotation of the hanger from moving as the locknut is moved along the kingpin.

Steering group of a motor vehicle comprising a front frame provided with a steering tube that rotatably houses a steering shaft or pin, which rotates about a steering axis, the front frame being provided with an upright integral with said steering tube, the front frame comprising a steering bracket, integral in rotation with the steering shaft. Advantageously, the steering group comprises elastic return means which elastically influence the steering shaft to position itself centrally with respect to the front frame, said elastic return means being placed and mechanically connected between the upright and the steering bracket in order to exert an elastic return action when the steering shaft rotates with respect to said central symmetrical position, wherein said elastic return means have a regressive trend elastic response.

A foot-deck-based vehicle having an adjustable steering characteristic is provided. The foot-deck-based vehicle has a foot-deck with a front end, a rear end, and at least one rear wheel proximal to the rear end. A front wheel assembly is coupled to the foot-deck proximal to the front end to pivot relative to the foot-deck about a front wheel assembly pivot axis that is at an acute angle to a vertical axis when the foot-deck-based vehicle is upright. The front wheel assembly includes at least one front wheel rotatably coupled to a front wheel support. A steering characteristic adjustment structure adjustably controls a steering characteristic of the foot-deck-based vehicle.

A personal mobility apparatus includes: a support platform having a pair of footplates and a cavity; two drive wheels disposed on both sides of the support platform, respectively; and a steering wheel connected to the support platform to be received in the cavity. The steering wheel is connected through a telescopic tube to be received in the cavity of the support platform and the telescopic tube includes a first tube and a second tube moving telescopically with respect to the first tube.

A vehicle includes a vehicle frame, a steering swivel unit supported on a head pipe of the vehicle frame and angularly movable about a steering axis, a front wheel angularly movable in unison with the steering swivel unit, and a steering handle mounted on the steering swivel unit. The vehicle has a steering handle turning mechanism that makes the steering handle angularly movable about the steering axis relatively to the steering swivel unit. The steering handle turning mechanism includes a handle turning motor for angularly moving the steering handle about the steering axis.
