A detachable modular electric skateboard which comprises a board body, wheel frames arranged at the bottom of the board body and provided with wheels driven by external force to travel together with the board body and the wheel frames, a traveling suspension part detachably installed at the end of the board body, and a power supply control part arranged at the bottom of the board body and provided with a detachably-installed battery assembly, and further discloses a remote control device for controlling the electric skateboard. Through the detachable traveling suspension part and the power supply control part, the advantages of existing electric skateboards and ordinary skateboards are integrated, a user can achieve the function switching according to requirements, and the detachable modular electric skateboard can replace daily vehicles driven by manpower and perfectly shows the recreational significance of ordinary skateboards serving as sports equipment.

A battery bracket for attaching, to an electrically assisted moving body capable of supplementing a first driving force generated by human power with a second driving force generated by electrical power, and a battery for use in the electrically assisted moving body. This battery bracket includes an extension section extending in a prescribed direction, and a plurality of projection sections projecting from the extension section in a direction intersecting the prescribed direction. The plurality of projection sections are mutually spaced along the prescribed direction.

A lightweight, compact electric drive unit provides high reduction ratios for a bicycle, light electric vehicle or autonomous device. A cycloid gear reducer includes one or more cycloid gears within a housing. The cycloid gears interact with gear teeth on the inside surface of the housing, and ride on a cam shaft having eccentric lobes. Output pins extend through apertures in the cycloid gears, from an input carrier to an output carrier. An electric motor powers the cam shaft, while the output carrier powers a drive train.

This motor driving control apparatus includes (A) a driving unit that drives a motor, and (B) a regeneration control unit that controls the driving unit so as to generate a regenerative 5 braking force in accordance with a vehicle acceleration, a vehicle speed and a pedal-rotation converted speed that is obtained from a pedal rotation.

A bicycle controller and bicycle drive device that improves the stability of the behavior of a bicycle. The bicycle controller includes an electronic control unit that reduces the output of a motor, which is configured to assist in propulsion of the bicycle, in accordance with an angular acceleration of a rotary body. The rotary body is included in a human power transmission path extending from an input for human power to a coupling portion coupled to a drive wheel.

A rechargeable battery pack (20) for an electric or hybrid vehicle (1), comprising: at least one electric connection member (23) to a powertrain unit (5) of the electric or hybrid vehicle (1); a plurality of mutually electrically connected cells (30); at least one first circuit block (40) integrated in the rechargeable battery pack (20) and comprising a radio communication interface (45).

A driving device for an electric vehicle includes a pedal shaft, first and second electric motors, an output shaft, and a superposition transmission whose gear ratio is steplessly adjustable by way of the electric motors. The transmission also couples the pedal shaft and the output shaft to each other. A torque generated by the first electric motor and/or the second electric motor can be at least partially transmitted to the output shaft. The driving device further includes an electronic anti-theft device used to lock the bicycle. When locked, at least one of the electric motors is operable to generate a torque that counteracts a rotation of the pedal shaft in a forward direction of rotation to inhibit theft of the bicycle.
