A three-wheeled vehicle having a front wheel assembly attached to a chassis. The chassis includes a rotational control shaft having a rotational axis that is generally directed in a longitudinal direction of the vehicle. The rotational control shaft is integrated with or secured to the chassis in a non-rotational manner and passes through the front wheel assembly in a rotationally-free manner, such that the rotational control shaft can rotate about its rotational axis. The front wheel assembly includes one or more lean control motors, which are operably configured to rotate the rotational control shaft about its rotational axis thereby causing the chassis to lean from side to side to improve the handling ability of the vehicle. Some embodiments include a lean control system configured to automatically control the degree of rotation of the chassis.

An autonomous electronic bicycle comprises a frame, a front wheel that can be powered by a first electronic motor, a rear wheel that can be powered by a second electronic motor, and handlebars that can steer the front wheel which can be controlled by a third electronic motor. Similarly, the autonomous electronic bicycle can comprise a set of sensors used for balance. The autonomous electronic bicycle can use the balance sensors to determine a current state of the autonomous electronic bicycle and drive the electronic motors to balance the autonomous electronic bicycle and achieve a target pose of the autonomous electronic bicycle. A neural network can be trained to determine one or more motor outputs of the autonomous electronic bicycle based on the target pose and the current state.

In some embodiments, a vehicle may include a frame having longitudinal axis. The vehicle may include a steering assembly having a steering input and at least one wheel. The steering assembly may be coupled to the frame and configured to steer the vehicle based on input from a steering input. The vehicle may include a first drive wheel and a second drive wheel. The vehicle may include a steering position sensor configured to detect steering input including a position of the steering input and at least one of i) a rate of change of position of steering input and ii) steering position time. The vehicle may include at least one controller configured to process a signal from the steering position sensor and, in response to the processed signal, drive the first drive wheel and the second drive wheel, the first drive wheel being driven independent of the second drive wheel.

A straddled vehicle, including a vehicle body having a rotatable handlebar; a steerable wheel, operation of which is transmitted mechanically to steer the steerable wheel; an actuator configured to apply a steering assisting force to the steerable wheel in accordance with the operation of the handlebar; and a control device configured to control the actuator by outputting a first physical quantity related to the steering assisting force, in accordance with a second physical quantity related to the operation of the handlebar. The control device performs, in response to an external instruction or fulfillment of a condition, setting or changing a dead band, which is a predetermined range of the second physical quantity in which the first physical quantity is not outputted even with the operation of the handlebar, and/or setting or changing an output increasing range in which as the second physical quantity increases, the outputted first physical quantity increases.

A vehicle includes a front wheel, a support of the front wheel, a steering handlebar, a platform and a front part joined to the platform. The support is rotatably mounted on the front part, and includes a driven rotating part, the handlebar having a driving rotating part. The driven rotating part and the driving rotating part are connected by Bowden Cables or hydraulic tubes. An impact absorber for a scooter is provided with a support of the front wheel formed by at least a leaf spring including a front end destined to bear the support of the front wheel, an opening adjacent to the front end destined to allow the passage of an upper prolongation of the scooter platform, and a rear end provided with two arms destined to support the rear wheel, such that the impact absorber constitutes the suspension of both the front wheel and the rear wheel.

A physiotherapeutic conveyance with a forwardly mounted wheel, a chassis relative to which said forwardly mounted wheel is mounted, a seat mounted relative to said chassis on a seating mount, a rear axle associated with a pair of outwardly disposed first and second rear wheels, and a steering assembly associated with said pair of outwardly disposed rear wheels, wherein said steering assembly comprises a steering mechanism operable to adjust the orientation of the rear wheels.

A mirror assembly for a handlebar of a vehicle has a stem assembly and a mirror connect to the stem assembly. The stem assembly includes a base, a stem connected to the base, and a clamp connected to and extending from the base. The clamp is adapted for being disposed inside a handle of the handlebar. The base, the stem and the clamp are integral. The clamp defines a ramp. A threaded fastener inserted through the base and extends in part in the clamp. A nut engages the threaded fastener, and at least a portion of the nut abuts the clamp. Translating the nut toward the base by rotating the fastener causes the nut to move over the ramp thereby deflecting the ramp.

Motorcycle including at least one rear wheel, at least two front steering wheels, a handlebar, the front wheels being rotatable about respective lateral steering axes, according to lateral steering angles; the handlebar being rotatable according to a central steering angle about a central steering axis, the front wheels being kinematically connected to the steering handlebar by transmission means that realize a transmission ratio defined by the ratio between the lateral steering angles and the central steering angle, where the transmission means has a steering bar, kinematically connected to the handlebar, which directly links the front wheels together, wherein the transmission ratio between the front wheels and the steering handlebar is variable as the central steering angle of the handlebar varies.
