In one embodiment, a micromobility transit vehicle may include a steering assembly. The steering assembly may include a steer tube configured to rotate within a headtube of the micromobility transit vehicle, and a stiffening brace positioned about the headtube. A stem may be coupled to the steer tube and the stiffening brace and configured to rotationally lock the stem and the stiffening brace together. A preload assembly may be coupled to the steering assembly and the stem and configured to adjust a preload of the steering assembly.

A bicycle stabilizer device includes a first post attached to a handlebar stem of a bicycle and a second post attached to upper frame portion of the bicycle; and a stabilizer bar configured to be reversibly connected between the first and second posts. Stabilizing a bicycle includes providing a stabilizer bar comprising a front portion end and a rear portion, attaching the second end to an upper portion of a bicycle frame. A post is disposed along a handlebar stem of the bicycle. The first end of the bar is reversibly connected to the post, the reversibly connecting stabilizing a front wheel of the bicycle to remain in a forward position.

A bicycle headset includes a first casing and a second casing for being engaged with a head tube and a fork of a bicycle, respectively. The first casing has an axial direction. A bearing abuts between the first casing and the second casing. A first restricting member, having a first restricting surface, is connected to the second casing to rotate along with the second casing. A second restricting member, having a second restricting surface, is connected to the first casing. The restricting members move away from or toward each other in the axial direction. An elastic member abuts between the first casing and the second restricting member or between the second casing and the first restricting member and provides a force in the axial direction for urging one of the restricting members to move toward the other to allow the two restricting surfaces abut against each other, thereby forcing the fork to steer back.

A steering system of a saddle-ride type vehicle includes a front fork that includes a steering shaft at the upper end and supports a front wheel at the lower end. A steering arm is attached to the steering shaft, a steering force transmit member is turnably supported by a steering stem that is arranged in a body frame, and a steering system link that joins the steering arm and the steering force transmit member. Engage sections are arranged between the steering force transmit member and the steering assist force transmit member. The engage sections allow the steering force transmit member and a steering assist force transmit member to be engaged with each other so that the steering assist force transmit member is turned around the steering stem accompanying turning of the steering force transmit member.
