A battery device of an electric bicycle includes a battery, a battery mount which allows attachment/detachment of the battery, a stepped portion, and a restriction release in a first end of the battery, and an engaging portion and a second movement restrictor in a first support of the battery mount. The engaging portion is restricted in its movement, by the second movement restrictor, from an engaged position where it is engaged by the stepped portion to a disengaged position where it is not engaged by the stepped portion. When the battery is to be removed, from the battery mount, the restriction by the second movement restrictor is removed, the restriction release is used to move the engaging portion from the engaged position to the disengaged position, and then the battery is pulled in a removal direction, to remove the battery from the battery mount.

A battery boost converter system for a bicycle includes a bicycle frame and a motor mounted to the bicycle frame. The system also includes a battery mounted to the bicycle frame and configured to provide power to the motor. The system also includes a boost converter configured to receive a first output signal from the battery and to provide a second output signal to the motor. The boost converter is also configured to determine, based on an operating condition, whether to boost a voltage of the first output signal such that the second output signal has an increased voltage.

A system and method for an electric bicycle battery anti-theft shield and/or cover that may be fitted to parts of an electric bicycle to hinder theft of the electric bicycle battery and/or components thereof. The system and method may also hinder theft of additional electric bicycle components and even hinder theft of the bicycle itself.

A regenerative braking energy dissipater system which is adapted to dissipate energy from a regenerative brake in the case when the battery cannot accept further energy. The system may switch the energy flow from the battery to a dissipater when the battery has reached a high level of charge. The dissipater may include load resistors. The system may be designed such that the airflow around the dissipater flows over and under the dissipating plate.

An electric-powered personal transport vehicle with a board to support a weight of a user and one or more wheels driven by one or more electric motors is discussed. The electric motors are powered by one or more batteries. A throttle has a thumb wheel speed controller on a handlebar. The thumb wheel speed controller has a horizontal manipulation between accelerate, neutral, and brake input positions such that pressing the thumbwheel speed controller in a vertical direction will not result in an unintentional acceleration or braking.

The invention relates to a lock including a locking mechanism having a latch that is movable between a latched position, which is provided for securing a counter-piece movable relative to the locking mechanism, and an unlatched position provided for releasing the counter-piece, and having an actuation element for manually moving the latch into the unlatched position. The lock furthermore includes a coupling element that can be transferred between a coupled state, in which it is coupled to the latch, and a decoupled state, in which it is movable relative to the latch, and that can be moved from a passive position into an active position by means of the actuation element, wherein the latch can be moved into the unlatched position by a movement of the coupling element, which is in the coupled state, from the passive position into the active position by the actuation element.

A bicycle frame element includes a frame tube, such as a downtube. The same forms an accommodation space for accommodating a battery. Further, a channel element is arranged in particular in the frame tube, which extends in the longitudinal direction of the frame tube, and serves to accommodate cables, wires, hydraulic lines and the like. To simplify the mounting, the channel element can be closed with a cover element. The cover element is held so as to be slidable in particular in the longitudinal direction.
