A personal mobility and a control method thereof may include a main body, a steering shaft rotatably coupled to the main body, a steering limiting device configured to limit rotation of the steering shaft, a posture sensor provided to detect a change in posture of the main body, and a controller configured to selectively generate a control signal to control an operation of the steering limiting device to limit the rotation of the steering shaft when the controller determines that the posture of the main body changes at a speed exceeding a predetermined speed.

An insert (510) comprising a core (532) and one or more extensions (530) extending from the core. The insert is adapted to be inserted into a cavity of a hollow tube-shaped member (512). The hollow member can be a motorcycle handlebar or footrest. The insert can be made of metal or a polymer and can be an extrusion product.

An elastomerically cushioned cycle stem, referred to as an e-stem, connects a cycle handlebar to a cycle fork steerer tube. The e-stem has a rigid interchangeable swingarm that rotates, i.e., pivots about an axis located behind a steerer tube bore of the base. A fastener rotationally secures the swingarm to the base and clamps the base to the steerer tube. An interchangeable elastomeric block, engaged by the base and swingarm, absorbs impacts from the road or trail, as the swingarm pivots. The base sides provide interior rotational abutments to the arms of the swingarm, the abutments buttress the pivoting swingarm to provide lateral rigidity of the swingarm relative to the base. The e-stem is adjusted using a plurality of swingarm configurations to alter the stem length and offset, and using a plurality of elastomeric block properties.

A handlebar shock absorbing device includes a sleeve in which a tube is co-rotatably inserted. A rod is inserted into the tube. A first spring is axially received in the sleeve and contacts the tube. A second spring is located in the tube and located between the rod and a cap on top of the tube. The first and second springs absorb shocks transferred to the handlebar.

A steering device, in particular for single-track vehicles, is provided. The steering device includes a support structure, an encapsulating casing which surrounds at least part of a surface of the support structure, and a vibration damper that is located within the encapsulating casing or between the encapsulating casing and the support structure.

The invention is adapted for use with a bicycle, where a handlebar is connected to a front fork tube through a stem tube having a stem seat and a handlebar seat. A pair of lug clip portions and a pivotal portion are provided between the stem seat and the handlebar seat and pivotally connected to each other through a pivotal assembly. At least one abutting portion is formed beneath the pivotal portion, and a shock-absorbing member is mounted beneath the at least one abutting portion. The pivotal assembly is provided atop with a press block which is secured to and tightly abuts against the pivotal assembly using a first fastening member. The press block is provided at its upper surface with an accessory fixation structure adapted for coupling an accessory to the stem tube. The accessory fixation structure enables rapid installation of accessories onto the stem tube.
