An electric scooter includes a deck, a power wheel unit, a power wheel steering unit, a driven wheel, a driven wheel steering unit, a power supply unit and a whole scooter controller. The power wheel unit includes a driving wheel; the power wheel steering unit is arranged between the deck and the power wheel unit; the driven wheel is spaced apart from the power wheel unit; the driven wheel steering unit is arranged between the driven wheel and the deck; the power supply unit is electrically coupled to the power wheel unit; the whole scooter controller is in communication with the power wheel unit and controls rotation of the driving wheel.

A transportation apparatus (1) comprises a frame (12) having an engagement portion or receiving portion (14) adapted to receive one or more occupant support devices (16); and drive means (20) configured to enable an occupant of the transportation apparatus (1) to power, drive and/or steer the transportation apparatus (1). The drive means (20) has a first configuration or position and a second configuration or position, wherein the drive means (20) is closer to the engagement portion or receiving portion (14) of the frame (12) in the second configuration or position than in the first configuration or position.

A tricycle that allows riding in adequate conditions over any type of terrain is disclosed, the tricycle having a structural frame onto which a seat and several pedals are incorporated, equipped with a rolling assembly made up of one rear wheel and two parallel front wheels, with the front wheels incorporated into two mounting forks equipped with several respective stems projecting upwards.

A powered wheeled riding device is configured to receive left and right foot inputs from a user and in response control a left motor and a right motor to move respective left and right wheels forwardly and backwardly consistent with the left and right foot inputs in order to steer the device without changing a direction of the wheels relative to a frame of the riding device. The riding device has at least one rear wheel that is not powered. The rear wheel is mounted on a wheel mount that rotates freely about a vertical axis so that the rear wheel freely is directed in any direction.

A structure for mounting a windshield includes: an adjustment support mechanism which supports the windshield such that the windshield is slidable with respect to a vehicle body; an operation element operated when a position of the windshield is adjusted; and a linear member connecting the adjustment support mechanism and the operation element. The adjustment support mechanism is switched between a position-adjustable state and a position-nonadjustable state by the operation element being operated.

A vehicle including a front module including a front wheel and a rear module selectively moveably connected to the front module, the rear module including a rear wheel. The vehicle further includes an electric motor assembly, a mode selector, at least one extension assembly connected between the front module and the rear module for selectively extending and retracting to provide a selective variation in an overall length of the vehicle; and a vehicle control unit being communicatively connected between the mode selector and the electric motor assembly. The vehicle control unit performs a method for selectively changing the overall vehicle length. The method includes receiving from the mode selector an indication to change the overall length, determining that the front wheel is rotationally locked, and causing an electric motor to drive the rear wheel such that the rear module translates relative to the front module.

A pedal unit attachable/detachable training bicycle that easily attach/detach a chain and a pedal unit to/from a training bicycle that has a seat stay. The pedal unit attachable/detachable training bicycle includes a bicycle frame having a receiving member provided at bottom of a seat tube to connect a pedal unit. The pedal unit, which is configured to detachably attach to the receiving member. A chain threaded between the pedal unit and a rear wheel. The bicycle frame is configured to enable a seat stay on side of the chain wheel to be freely attached to and detached from the bicycle frame.
