A bike includes a frame elongated in a longitudinal direction, a front fork rotatably engaged with a front wheel at a front end of the bike, a rear fork rotatably engaged with a rear wheel at a rear end of the bike, a handlebar supported for rotation at the front end of the frame for steering the bike, and a drive module configured to drive the rear wheel of the bike when operated selectively with power. The frame includes a down tube extending downward and rearward from the front end of the bike and a drive module enclosure formed at a second end of the down tube. The drive module enclosure defines a drive module receptacle that is open along the longitudinal direction of the bike. The drive module receptacle is sized to receive the drive module along the longitudinal direction of the bike.

The disclosure relates to an electric Bicycle Drive Unit for arrangement in a Bottom Bracket Area of a Bicycle Frame. The Drive Unit has an Electric Motor Device and a Bottom Bracket Assembly having a Bottom Bracket Shaft. The disclosure also relates to a Bicycle Frame or Frame Interface Unit, and an Energy Storage Device for the Electric Bicycle Drive Unit. The Drive Unit includes s an Integrative Energy Storage Device for supplying energy to the motor device. The Integrative Energy Storage Device can be arranged adjacent to the motor device in such a way that the center of gravity position of the Energy Storage Device and the center of gravity position of the Drive Unit lie within the Bottom Bracket Area.

A holding device for releasably holding an accumulator, in particular a bicycle accumulator, on a frame, especially a bicycle frame, and includes at least a carrier unit provided with at least a carrier element, especially a guide rail, for the at least partial accommodation and/or guidance of the accumulator. The holding device has at least a variation unit situated at least partially on the carrier element for the variable positioning of a locking unit at different positions of the carrier element, in particular viewed along a longitudinal axis of the carrier element.

A bicycle drive unit includes a motor, a second electronic controller and a communication circuit. The motor is configured to assist in propulsion of a bicycle. The second electronic controller controls the motor. The communication circuit is configured to communicate with an operation device that operates a bicycle electric component. The second electronic controller is operable in a third state, in which the motor is drivable, and a fourth state, which consumes less power than the third state and does not drive the motor. The second electronic controller is configured to switch an operation state from the fourth state to the third state upon the communication circuit receiving an input signal while the second electronic controller is operated in the fourth state.

A bicycle frame is discussed having a battery fully contained within a down tube of the bicycle frame. The battery may be inserted into or removed from the down tube via a through opening through a bottom bracket housing of the bicycle frame. Weakness in the bottom bracket housing due to the through opening may be compensated for, fully or partially, by utilizing a bottom bracket bearing assembly that has a structural component, or structural component assembly, that extends completely through the bottom bracket housing and removably couples to the bottom bracket housing.

An electric mobility apparatus is disclosed. The electric mobility apparatus may include a steering assembly including a handlebar manipulated by a user and a support shaft having one side coupled to the handlebar, a mid-frame assembly including a user boarding part formed on an upper end, a front frame assembly having one side coupled to the support shaft and the other side on which a first connector having at least a portion fastened to one side of the mid-frame assembly is formed, and a tail frame assembly including a second connector of which at least a portion is fastened to the other side of the mid-frame assembly.
