A steering system includes: a base including a first structure and an axial hole defining an axial direction; a shaft rotatably inserted in the axial hole; a rotatable seat including a second structure located on a side of the rotatable seat facing the base, the rotatable seat being connected to and movable with the shaft; and at least one elastic member arranged around the axial direction and abutted against and between the first and second structures, wherein when the rotatable seat rotates relative to the base, the at least one elastic member is forced by the first and second structures and generates a deformation around the axial direction. A scooter includes the steering system, and further includes: a deck connected to the base; a steering mechanism including the shaft; and a plurality of wheels connected to the deck and the rotatable seat, respectively.

Systems and methods related to intuitive electric steering for a motor-driven vehicle. One example system includes a first clutch mechanism, a second clutch mechanism, a handlebar for steering the vehicle, and an electronic controller. The first clutch mechanism is configured to control torque power provided to a first wheel on a left side of the motor-driven vehicle. The second clutch mechanism configured to control torque power provided to a second wheel on a right side of the motor-driven vehicle. The handlebar is configured to pivot about an axis. The electronic controller is configured to detect a pressure applied to the handlebar, relative to the axis, by an operator of the motor-driven vehicle. The electronic controller is configured to determine a desired turn direction of the motor-driven vehicle based on the pressure and control the first clutch mechanism and the second clutch mechanism based on the desired turn direction.

A tricycle having limited steering includes a front wheel mounted to a lower end of a wheel fork. A support tube is connected to a frame. A seat is mounted to the frame. A rear axle is included. Rear wheels are mounted to the rear axle. An upper end of the wheel fork extends upwards and into the support tube. A mudguard has front and back portions configured to extend over portions of the front wheel and side portions configured to extend over portions of the lower end of the wheel fork. A projection has an upper end arranged above an annular surface of the mudguard.

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 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.

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.

An apparatus provides a restoring moment for a two-wheeler steering mechanism. A mounting device mounts the apparatus on a two-wheeler frame. A coupling device couples the apparatus with a fork shaft, and has a rotational axis. An energy storing device stores a restoring force. A force transmitting device transmits steering force to the energy storing device. The force transmitting device has a force transmitting point that is eccentric to the rotational axis, and forms a force action line through the eccentric force transmitting point and an application point of the force transmitting device on the energy storing device for transmitting the steering force to the energy storing device. In a neutral position of the apparatus, the force action line and a straight line running through the rotational axis and the application point enclose an angle. A two-wheeler frame, a two-wheeler steering and a two-wheeled vehicle are also provided.
