Various ridable karts for users are described. The ridable kart can include a kart body, a cover body, a rear caster wheel, a steering assembly, a battery, and a controller. The kart body can include an installation slot. The controller and the battery can be secured within the installation slot. The steering assembly can include a front wheel and a steering wheel. The front wheel can include a hub motor arrangement.

A kart having a pedal speed controller and other components and arrangements thereof are disclosed. The kart can be provided with a controller for controlling speed; the pedal speed controller comprising a pedestal and a pedal, one end of the pedal is articulated with the pedestal and keeps a certain angle with the pedestal. The pedal speed controller also comprises a sensor connected with the controller, and the sensor can obtain displacement signal along the tread direction of the pedal. The pedal speed controller has the advantages of realizing pedal control of acceleration or deceleration for drivers, avoiding interference with manual adjustment of kart direction, preventing from mutual influence between speed regulation and steering, improving the speed control performance of the kart, and improving the driving experience.

The invention relates to a trailer that is especially used for moving over very soft ground and for launching lightweight boats, comprising a motor-driven supporting running gear (11) designed to hold the hull of the boat and extended by a longitudinal edge (12) ending in a lift jack (13) comprising a maneuvering handle (132). The supporting running gear (11) comprises an essentially tubular frame (111) arranged transversely to the longitudinal axis of the trailer, and to which a sealed differential-motor reducer unit (14) or an electric motor could be fixed.

A vehicle includes a vehicle frame including a first frame rail, a second frame rail spaced cross-vehicle from the first frame rail, and a middle frame rail between the first frame rail and the second frame rail. The first frame rail and the second frame rail each have a vehicle-inboard side facing toward the middle frame rail. The vehicle-inboard sides each define a plurality of notches. The middle frame rail has a downward side facing downwardly and perpendicular to the vehicle-inboard sides. The downward side defining a plurality of notches. The vehicle frame has a rear cross-member and a front cross-member spaced vehicle-forward of the rear cross-member. The rear cross-member and the front cross-member are between the first frame rail and the second frame rail. The notches of the vehicle-inboard sides and the notches of the downward side are between the rear cross-member and the front cross-member.
