A bicycle includes a transmission having two switchable drives between a driver body on which rear sprockets are positioned and a wheel hub of a rear wheel. The bicycle has actuation elements for switching between drives and operating elements for operating the actuation elements. The bicycle includes only a single front sprocket. The actuation elements are embodied in an electrical version and the operating elements are electrically coupled to the actuation elements. By advantageously selecting the drives of the driver between the cassette housing and wheel hub, a front derailleur may be omitted. The driver allows operation with only little energy, since the chain need not be shifted. consequently, the actuation elements require little energy for changing the drive between the crank axle and the wheel hub of the bicycle, so that it is pre-eminently suitable for these actuation elements and their operation to be executed as an electrical version.

A rear derailleur of a bicycle includes a fixing portion connected to a frame of the bicycle, a linkage assembly pivotally connected to the fixing portion, a moving portion pivotally connected to the linkage assembly, a chain guide assembly connected to the moving portion, a driving assembly, a rechargeable battery for providing an electrical energy required for the motor, a coil, and a wireless charging circuit for receiving an electric power of the coil for charging the rechargeable battery. The driving assembly includes a motor including and a driving gear assembly connected to the linkage assembly. The motor includes an output shaft for driving the driving gear assembly and for driving the linkage assembly to pivot via the driving gear assembly, thereby to drive the moving portion and the chain guide assembly to move. The coil receives an external charging power and is disposed on the fixing portion, the moving portion, or the linkage assembly.

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 saddle riding vehicle includes: an engine disposed between a front wheel and a rear wheel; a fuel tank disposed above the engine; a generator mounted to a crankshaft of the engine; and an inverter that supplies output of the generator to a battery. The inverter is disposed behind a head pipe, above a crankcase and below the fuel tank.

A self-powered motorcycle or bicycle includes: a pair of shock absorber frame housings (101), each having a cylindrical hollow inside, a closed upper end portion, a split space formed at a lower end portion, rack gear moving holes (101a) respectively formed in both sides of the outer wall in a longitudinal direction, and self-powered generators (100) respectively mounted on both sides of the outer wall, the pair of shock absorber frame housings being mounted to face each other; a pair of shock absorber frames (102); disc-shaped partitions (102c) fixed in a horizontal direction; anti-rotation protrusions (104a) formed at both sides of the spring guide in a longitudinal direction; and anti-rotation protrusion guide holes (102b) formed at both sides of the shock absorber frame.

A motorcycle, or saddle type vehicle, is disclosed that may have at least one seat and at least two wheels, at least one hub electric motor. A large dry storage compartment may be positioned between the rider and steering mount. A rechargeable battery and battery management system may be located below the storage compartment in a battery housing, where the battery housing may be a structural component of the chassis. A rear electronics housing may be attached to and located behind the battery housing, and may contain major electrical components such as electric motor controller and contactors. Two structural members, or frame side rails, may form sides of the storage compartment and extend between the electronics housing and steering mount. The electronics housing may also connect to the battery housing such that the battery housing reinforces and strengthens the chassis, or structural frame. A secondary storage compartment may be located under the seat. Additionally, the storage compartments may have electronic locking mechanisms that are activated via a wireless connection to a remote electronic device. The rear suspension may include a swingarm on one side of the vehicle.

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.

The present invention is directed toward an accessory mounting system. The accessory mounting system can be used to mount an accessory to a vehicle. The accessory mounting system includes a base assembly and an accessory assembly. The base assembly can be fixedly positionable on the vehicle about a first axis, the base assembly including a first locking member and a base assembly second member. The accessory assembly can be removably securable to the base assembly. The accessory assembly can include a second locking member that selectively engages the first locking member. The accessory assembly can be rotatable about the first axis relative to the base member. The accessory mounting system can further include a charger that receives the accessory assembly. The charger can include a charge receiver engager that electrically engages the charge receiver, and electrically disengages from the charge receiver.
