A left suspension unit supports a left wheel. A right suspension unit supports a right wheel. A steering actuator imparts a force causing the left suspension unit and the right suspension unit to turn about a left steering axis and a right steering axis respectively to a steering force transmission mechanism. A leaning actuator imparts a force causing a body frame to lean leftward or rightward of a leaning vehicle to a link mechanism. A control unit is capable of selecting a first mode wherein both of the steering actuator and the leaning actuator are employed, and a second mode wherein the steering actuator is employed without employing the leaning actuator, in order to control a leaning angle of the body frame in cooperation with a steering mechanism.

A hybrid pump-action vehicle and therapy device may include a pumping arm attached to a lower pump-action assembly. As the pumping arm is actuated, the lower pump-action assembly moves forward and rearward in response to the pumping action and powers movement of the vehicle. The lower pump-action assembly may be releasably connected to the pump arm so that the pump arm can be disengaged from the pumping action but still be usable for steering. A motor may also be provided to provide assistance or full power to the vehicle based on a user-selectable amount of assistance. And finally, the vehicle may be configured such that it can be collapsed to a fraction of its operating footprint to enable easy transport and storage.

An autonomous electronic bicycle comprises a frame, a wheel that can be powered by a first electronic motor, and a pedal assembly connected to a pedal motor. The pedal assembly is not mechanically connected to the wheel, but the autonomous electronic bicycle simulates a mechanical connection by powering the rear wheel proportional to the user's pedaling force. The autonomous electronic bicycle uses a virtual gear ratio based on the cadence of the rider, the current incline of the bicycle, and the current speed of the bicycle. The virtual gear ratio can be a ratio between a torque of the set of pedals and a torque of the wheel.

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.

This invention is an electric unicycle. It is an improvement of a unicycle and a self-balancing electric unicycle. It comprises one wheel (1B), brushless DC motor (1C), operating-pedal (1D), seat (2A), pneumatic springs (2B) for shock absorb, mainboard (1F), lithium-ion battery pack (1G), telescopic handle (1I), emergency brake footboard (1J), casing (1H). The emergency brake footboard (1J) can be easily mounted and unmounted and folded. While in using, the user generally rides on the seat, swings their foot, to adjust the depression angle of the operating-pedal (1D), to control the wheel rotation, rather than by an electric gyro. Thus, this invention is easy to operate, easy to learn, easy to use, flexible, portable, zero emission, great trafficability. It will become the main short-distance means of transportation for cities and villages, and even can be used in poor road conditions, such as field exploration and forest patrol.

A leaning vehicle, including a vehicle body, one steerable front wheel and two rear wheels, or two steerable front wheels and one or two rear wheels, a suspension mechanism, a steering mechanism, a steering controller, and an up-down direction acceleration detector attached to the vehicle body or the suspension mechanism. The two steerable front wheels or the two rear wheels are arranged side by side to form a left-right pair of wheels. The up-down direction acceleration detector detects an acceleration in an up-down direction of the leaning vehicle or the vehicle body, generated as one wheel in the left-right pair of wheels passes a bump or a pothole in a road. The steering controller so controls the one or two steerable front wheels that the one or two steerable front wheels are in a free-steering state, so as to swivel around a steering axis freely, based on the detected acceleration.

A hydration system including a fluid reservoir, a fluid path in communication with the reservoir, and a magnetic quick connect interposed in the fluid path is disclosed. A fluid delivery system for a hydration system is also disclosed that includes a magnetic quick connect interposed in a fluid delivery path of the delivery system. The magnetic quick connect can also be used in a wide variety of fluid delivery systems. A kit for forming a fluid delivery system for a hydration system is also disclosed, as are various components of a hydration system.

A vehicle includes: a vehicle body; one or more turn wheels turnable to right and left; a lean actuator configured to apply a lean torque to the vehicle body; a turn wheel support unit; and a controller. The turn wheel support unit includes: a supporting member that rotatably supports the one or more turn wheels; and a turning actuator configured to apply a turning torque to the supporting member. The controller is configured to determine a target lean angle, and determine the target lean torque and the target turning torque using the target lean angle.
