The invention concerns a wheeled vehicle (10) which is able to regulate its lateral tilt. In a preferred aspect the vehicle (10) comprises a seat (28) for supporting a rider, and a chassis (18) which carries the seat. A steerable wheel (12) is carried by the chassis and is operably coupled to a steering arrangement (30, 34) for turning the steerable wheel (12) to effect steering of the vehicle (10). A left wheel-bearing arm (66) carries a left wheel (14) and is pivotally coupled to the chassis (18), so that pivotal movement of the left wheel-bearing arm (66) provides up and down movement of the left wheel (12) relative to the chassis (18). A right wheel-bearing arm (68) carries a right wheel (16) and is pivotally coupled to the chassis (18) to be movable independently of the left wheel-bearing arm (66), so that pivotal movement of the right wheel-bearing arm (68) provides up and down movement of the right wheel (16) relative to the chassis (18). A left control line (76) is led from a left tether (79) on the left wheel-bearing arm (66) to an actuator (84) carried by the chassis (18), so that upward movement of the left wheel (14) relative to the chassis is restrained by the control line (18). A right control line (82) is led from a right tether (78) on the right wheel-bearing arm (68) to the actuator (84), so that upward movement of the right wheel (16) relative to the chassis (18) is restrained by the right control line (82). The actuator (84) is operable in a first direction to pay out the left control line (76) whilst drawing in the right control line (82), permitting the left wheel (14) to move up relative to the chassis (18) and causing the right wheel (16) to move down relative to the chassis (18), thereby causing the vehicle (10) to tilt toward the left. The actuator (84) is operable in a second direction to pay out the right control line (82) whilst drawing in the left control line (76), permitting the right wheel (16) to move up relative to the chassis (18) and causing the left wheel (14) to move down relative to the chassis (18), thereby causing the vehicle (10) to tilt toward the right.

An electric powered personal mobility vehicle that includes at least one front wheel and an electric motor that provides rotational force to a wheel of the vehicle. The electric motor is supported by the vehicle and is powered by a rechargeable battery that is also supported by the vehicle. The vehicle can also include swivel caster wheels each configured to rotate about a wheel axis.

A battery housing apparatus including a housing portion forming a housing space in which a battery is removably housed, a holding portion configured to hold the battery, and an openable cover portion closing the housing space. The housing portion includes a support portion rotatably supporting the holding portion about a rotational axis so that the battery is movable between a housed position and a non-housed position in the housing space.

Drifting karts in accordance with embodiments of the invention are described that include a front wheel drive train and rear caster wheels that can be dynamically engaged to induce and control drift during a turn. One embodiment of the invention includes a chassis to which a steering column is mounted, where the steering column includes at least one front steerable wheel configured to be driven by an electric motor, a battery housing mounted to the chassis, where the battery housing contains a controller and at least one battery, wiring configured to provide power from the at least one battery to the electric motor, two caster wheels mounted to the chassis, where each caster wheel is configured to rotate around a rotational axis and swivel around a swivel axis, and a hand lever configured to dynamically engage the caster wheels to induce and control drift during a turn.

A mobility scooter control system includes a remote control console having a wireless transmitter and switches. A status detection circuit is integrated with the switches. The status detection circuit emits a pulse on a regular cycle. After the pulse passes the respective switch following a change in state of the switch, a wireless transmission is sent. A controller is electronically connected to a motor. The control system has a regular operation mode in which direction of movement and speed limit functions are responsive to instructions inputted to the controller, and, in the absence of user instruction, the controller does not instruct movement of the motor. The control system has a Sabbath operation mode in which the direction of movement and speed limit functions are responsive only to signals from the wireless transmitter, and, in the absence of user instruction, the controller instructs the motor to continuously cycle backward and forward.

An electric bicycle includes a frame that has a concave or arc shape. The bicycle also includes two wheels—a front wheel and a rear wheel, with each wheel being connected with an end portion of the frame. A battery-powered electric motor may be connected with the rear wheel to drive the rear wheel and propel the bicycle forward. The battery may be rechargeable. The speed of the bicycle may be controlled by the operator moving a lever with one of their feet. A rotatable knob located on the frame may be used as a cruise control speed setting device. The electric bicycle may be steered by the operator using their feet resting on a pair of foot pegs that are attached to or connected with the front wheel. The electric bicycle may include a regenerative braking system or a friction braking system.

A pump-action mobility vehicle may include a pumping arm attached to a foot slide. As the pumping arm is actuated, the foot slide moves forward and rearward in response to the pumping action. The foot slide may be connected to a drive mechanism that selectively engages a chain or belt that loops around a drive wheel arranged on an axle of the vehicle. When the drive mechanism catches and moves the belt or chain in a forward direction, the axle rotates in a forward direction to drive the vehicle forward. A reverse mechanism may also be provided that selectively causes the drive mechanism to catch and drive the belt or chain in an opposite direction.
