A control device sets a second electricity control switch in an intermediate state in a process of switching a discharge battery for supplying a drive unit with an electrical current from a first battery to a second battery. Subsequently, when a comparative relationship between an electric potential of a smoothing capacitor and an electric potential of the second battery fulfills an intermediate state termination condition, the control device sets the second electricity control switch in a bidirectional conduction state. The intermediate state is when an electrical current flowing from the second battery to the drive unit is allowed, and an electrical current flowing from the drive unit to the second battery is inhibited. The bidirectional conduction state is when both of the electrical current flowing from the second battery to the drive unit and the electrical current flowing from the drive unit to the second battery are allowed.

An electric bicycle assembly for propelling a bicycle includes a bicycle that includes a first chain sprocket and pedals coupled to the first chain sprocket for rotating the first chain sprocket to propel the bicycle. A second chain sprocket is coupled to the first chain sprocket such that the second chain sprocket is rotated when the first chain sprocket is rotated. A generator is coupled to the bicycle and the generator is rotated to generate electrical energy when the pedals are pedaled. A motor is coupled to the bicycle and the motor is in mechanical communication with the rear wheel. The motor rotates the rear wheel when the motor is turned on for propelling the bicycle.

A battery holder 54 for fitting a battery pack 52 to a frame 4 of a cycle 2 comprises a spine portion 100 for fixing to the frame 4; a connector portion 110 to form an electrical connection between the battery pack and wiring; and a battery moving portion 115 for moving the battery pack 52 towards the connector portion to engage the battery pack with the connector portion. A lever mechanism 120 actuates sliding of the battery moving portion 115 in a linear direction between an open state providing clearance for insertion/removal of the battery pack and an engaged state for engagement of the battery pack 54 and connector portion 110. The lever mechanism 120 has a retained state which provides resistance to removal of the battery pack from the battery holder. This provides a simple to install and fasten holder which securely holds the battery pack.

A foldable bicycle structure comprises a supporting frame (2) having a rear wheel (3) and a front wheel (4), a handlebar (5) fastened to the frame (2) and a seat post (6). The supporting frame (2) is divided into a front portion (9) and a rear portion (10) adapted to be connected to respective wheels (3, 4) and reciprocally hinged around a first hinge axis (11) to switch between an extended use configuration to a compact configuration. The supporting frame (2) is also provided with one or more straps (14, 15) each having one end fixed to the supporting frame (2) and one free end provided with a hook to allow the respective strap to be unwound (14, 15) and its hooking to another part of the structure and be used as a shoulder strap for transporting the structure in a compact configuration.

A bicycle battery system includes a battery assembly and a battery lock. The battery assembly includes a battery and a handle assembly mounted to the battery. The handle assembly includes a handle mount, a handle plunger, and a handle. The battery lock is mounted within a cavity of a frame of a bicycle and configured to secure the battery assembly within the cavity. The battery lock includes a lock plunger, a movable latch, and a stationary latch. The lock plunger is configured to press a portion of the handle mount against the movable latch when the battery lock is in a locked position such that the battery assembly is securely mounted within the cavity. Responsive to the battery lock being in an unlocked position, the handle plunger is configured to cause the handle mount and the handle to pivot away from a face of the battery such that at least the portion of the handle mount engages the stationary latch of the battery lock.

A lock, in particular for an electric bicycle, includes a locking mechanism that has 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. The lock includes a blocking device, including a blocking element that is adjustable between a blocking position, in which the latch is blocked in its latched position, and a release position in which the latch is movable into its unlatched position, and a reception unit for receiving a release signal by which the adjustment of the blocking element into the release position can be brought about. A locking system may include at least one such lock.

An operating device of a human-powered vehicle, the device including: an operation member; a base that is configured such that the operation member is provided to the base and at least a part of the base is embedded in a vehicle body of the human-powered vehicle; at least one interface; and a controller that is provided to the base and is electrically connected to the at least one interface, the controller being configured to cause the at least one interface to output a control command to a control-target in accordance with an operation of the operation member, wherein the controller is configured to be capable of changing at least one of the control-target and the control command.
