A passenger trailer apparatus for towing a passenger behind a mobility scooter is provided. The mobility scooter has a tow bar or hitch. The passenger trailer apparatus comprises a trailer frame and an axle mounted to and through the trailer frame. A tire is rotatably, releasably mounted to each end of the axle. The platform has a top surface and a bottom surface with the bottom surface of the platform mounted to the trailer frame. A chair assembly is mounted to the top surface of the platform with the chair assembly sized and shaped for receiving a passenger. A receiver bar having a first end and a second end is provided. The first end of the receiver bar is connected to the platform and the second end of the receiver bar capable of being releasably connected to the tow bar or hitch of the mobility scooter. The passenger trailer apparatus provides secure, reliable performance, quick assembly and breakdown, and easy transport and storage.

Disclosed is a self-balancing scooter with a foldable foothold for an additional rider. The self-balancing scooter includes: a housing; a controller mounted inside the housing for controlling running and direction change; motors respectively mounted at both sides of the housing; wheels respectively mounted on shafts of the motors; a battery mounted on the bottom surface of the housing; a riding board mounted on the upper part of the housing to allow a main rider to put feet; a foldable foothold attached to the side wall of the riding board to allow an additional rider to put feet; casters mounted at one side of the foldable foothold; a fitting hole formed at the other side of the foldable foothold; and a bracket assembled to the fitting hole through a rotary shaft and attached to the side wall of the riding board, the bracket having assembly holes.

Tow bar arrangement (100) for interconnection of a pulling vehicle (10) and a pulled trailer (20). The arrangement (100) comprises a control device (110) with a force sensor (111) arranged to sense an instantaneous relative force between vehicle (10) and trailer (20). The control device (110) is arranged to produce a control signal for an electric motor (21) arranged to propel the trailer (20) so that a motor force counter-acts said measured force. The invention is characterised in that the control device (110) is arranged to a first time series of force measurements, in that the control device (110) comprises a low-pass filter (112) producing a second low-pass filtered time series, and in that a regulator (113) is arranged to regulate said second time series to produce said control signal.

A tricycle may be operable between a first mode of operation steerable by a tricycle rider, and a second mode of operation steerable by an individual pushing the tricycle. A rider handle, in the first mode, may be configured to be rotationally coupled with the stem in a manner permitting a tricycle rider to exert forces on the rider handle and thereby turn the fork, and the rider handle in the second mode, being configured to be rotationally uncoupled from the stem, preventing forces on the rider handle from turning the fork. At least one rotation restricted may be included for preventing the front wheel from turning to a position where the front wheel axis leads the fork axis, and for maintaining the front wheel axis in a position trailing the fork axis both when the tricycle is propelled by a tricycle rider in the first mode and when the tricycle is pushed from behind in the second mode.

An apparatus for a wheelchair caddy to be attached to a disabled rider adapted cycle or scooter that may include connectors connecting the caddy and cycle, a rear or double rear axle attached to the base of the caddy frame, a handle for the user to grip while pulling the wheelchair onto the caddy, a rod as an emergency brake, a ratcheting strap or straps and bungee cord for securing the wheelchair in the caddy, walled footwells for the securing the passengers feet, a secured foam rubber middle console, a fitted, padded back rest, thigh restraining straps, lower ribcage restraining straps and other features.

A trailer system includes a chassis defining an axis and having a first section and a second section removably attached to the first section. A wheel assembly is attached to the first section that includes a single wheel and a lift mechanism arranged to raise and lower the chassis relative to the single wheel.

A tricycle may be operable between a first mode of operation steerable by a tricycle rider, and a second mode of operation steerable by an individual pushing the tricycle. In both such first and second modes, the frame of the tricycle is configured to rotatably support the rear wheels and configured to support the head tube at a distance from the rear wheels such that a distance between the head tube and rear wheels need not necessarily be changed even when the front wheel axis location is changed from one mode to another.

An electric bicycle charger assembly includes a trailer that can be attached to a seat post of an electric bicycle thereby facilitating the electric bicycle to tow the trailer. A pair of wheels is each of the wheels is rotatably attached to the trailer and a pair of charging units is each integrated into a respective one of the wheels generate electricity when the trailer is being towed. Each of the charging units is electrically coupled to the electric bicycle for charging the electric bicycle. A braking system is integrated into the trailer and the braking system is in communication with a braking apparatus of the electric bicycle thereby assisting with slowing and stopping.

An operating device for a vehicle comprises an outer unit that can be rotated manually, a detection device configured to detect the movement of the outer unit and generate a control signal using a value that characterizes the movement to control a vehicle function, and an actuator unit that contains a magnetorheological medium, which can be or is coupled to the outer unit and is configured to exert a retaining force on the outer unit based on the viscosity of the magnetorheological medium. The operating device also comprises a sensor unit located in the outer unit and configured to generate a hand signal indicating the absence of a user's hand on the outer unit, and a manipulating device for manipulating the control signal on the basis of the hand signal.
