A bicycle can include a forward frame triangle that can include a top tube, a bottom tube, a bottom bracket, a structural seat tube, a compliant seat tube, and a pair of seat stays. The top tube can have a first end connected to a head tube and a second end. The bottom tube can have a first end connected to the head tube. The bottom bracket can be connected to the bottom tube. The structural seat tube can be connected to the bottom bracket and the top tube. The compliant seat tube can extend in an upward direction from the bottom bracket to the top tube and within the structural seat tube. The compliant seat tube can be coupled to the forward frame triangle such that the compliant seat post can bend within the structural seat tube.

A vibration absorbing handlebar of a bicycle has a steering module, a left handle, and a right handle. The steering module has a stern. The left handle has a bar, and a first elastic component having two ends. One of the two ends of the first elastic component is connected with an end of the bar, and the other one of the two ends of the first elastic component is connected with the stem. The right handle has a bar, and a second elastic component having two ends. One of the two ends of the second elastic component is connected with an end of the bar, and the other one of the two ends of the second elastic component is connected with the stem.

A motorized foldable bicycle assembly is foldably collapsible from a ridable elongated, segmented four sectioned frame arrangement. The frame consisting of a front wheel support frame, a front frame, a mid frame and a rear wheel support frame, with a set of electronically controlled motorized front and rear wheels spaced longitudinal alignment, apart one on each end of the four-sectioned elongated frame arrangement. The frame sections are foldable into an unridable configuration wherein the front wheel and a displaced rear wheel are arranged in an aligned, side-by-side adjacent, tandem configuration controllably guided by a steering column supported handlebar motor speed and direction control arrangement. A bicycle-supported tilt sensor actuator is in communication with a control computer and a circuit electronically connected to a bicycle handlebar switch, to permit operator controlled non-riding, self-powered, electric-motor-engaged movement of the tilted, partially foldably collapsed bicycle.

An apparatus, system, and method are disclosed for adjusting a height of a handlebar. The apparatus includes a steering tube coupling member, a handlebar coupling member, at least one connector and a height adjusting member. The at least one connector adjustably couples the steering tube coupling member to the handlebar coupling member. The height adjusting member is coupled to at least one of the steering tube coupling member, the handle bar coupling member, and the at least one connector. Actuation of the height adjusting member selectively adjusts a height of the handlebar coupling member relative to a height of the steering tube coupling member to selectively adjust a height of the handlebars.

Disclosed is a single-wheeled balance vehicle. The single-wheeled balance vehicle includes: a wheel provided on a wheel frame, a motor transmission mechanism fixed in the wheel frame and arranged to drive the vehicle according to acquired manned mode information; a wheel cover arranged to partially cover the wheel; a skeleton arranged to reinforce mechanical strength of the wheel cover; and footboards arranged to be stepped on by both feet of a driver in driving. The wheel cover partially covers the wheel and in embodiments may be in a surface contact, so that the contact area is larger, contact stress is more dispersive, a strain is relatively small, the deformation of the wheel cover can be reduced, the possibility that a tire or a hub motor is rubbed or locked due to deformation of the wheel cover in the related art can be avoided, and safety performance can be improved.
