Abstract: A system of bracket assemblies for a wheelchair comprises a pair of bracket assemblies adapted to be connected to respective sides of a seat frame of the wheelchair. Each of the bracket assemblies has a base adapted to be secured to a seat frame member of the seat frame, an arm adapted to be secured to a backrest frame member of a backrest frame, and a pivot pivotally connecting the base to the arm for rotational movement of the arm relative to the base. One or more blocking mechanism blocks the rotational movement of the arm relative to the base in a use orientation of the backrest frame. A rod having opposed ends connected to the base of the pair of the bracket assemblies for spacing the bracket assemblies away from one another. A rear wheel unit is also provided.

Abstract: An internal motorized bicycle hub includes a hub axle, a motor, a first bearing, a second bearing, a spacer and a movement restricting section. The motor has a rotor and a stator. The first and second bearings rotatably support the rotor on the hub axle. The second bearing is axially spaced apart from the first bearing. Each of the first and second bearings includes an inner race attached to the hub axle, an outer race attached to the rotor, and a rolling element arranged between the inner and outer races. The spacer is arranged between the inner races. The movement restricting section restricts movement of the inner race of the first bearing in a direction of separating from the bearing of the second bearing. The spacer presses the bearing of the first bearing towards the movement restricting section.

Abstract: An electric hub unit includes a hub composed of first casing and a second casing. An electric unit is located between the first and second casings. An axle extends through two respective centers of the first and second casings. The first casing has a reception recess defined in one side thereof. A first extension and a second extension extend axially from the first casing and toward in opposite directions. A bearing is located in the inside of the second extension. A socket unit has a tubular portion and a ratchet unit is connected to the socket unit. The socket unit is mounted to outside of the first casing, and a bearing and a plate are located between the tubular portion and the first extension. The hub unit prevents water and foreign objects from entering into the hub.

Abstract: The automatic gear bike includes a control system for selectively operating in an automatic mode, providing power to the bike or a manual mode. The control system includes a control assembly, a motor assembly operatively in communication with the control assembly, and a gear assembly in operative engagement with the motor assembly. The gear assembly includes a ration gear, a hub, and hub embedded gear. The ration gear is operatively connected to the beam gear, and the hub embedded gear is connected to the hub. The controller receives detects the real-time bike speed, and compares the bike speed to a pre-selected bike speed. Based on the comparison the controller sends a signal to the motor assembly to selectively transfer power to the beam gear and operatively connected gear assembly, to increase or decrease the bike speed such that the real-time bike speed is substantially equal to the pre-selected speed.

Abstract: An electric power-assisted bicycle includes a transmission mechanism (3), a speed reduction mechanism (16) and a drive motor (15) which are arranged in parallel in the direction of the an axle, inside a rear hub (1) of a drive wheel. The transmission mechanism (3) and the speed reduction mechanism (16) are each formed by planetary gear mechanisms, and a planetary carrier (3c) is shared between the transmission mechanism and the speed reduction mechanism.

Abstract: A hub shell of a hub assembly is rotatable about a fixed hub shaft. A power transmitting member is disposed within the hub shell. A pawl supporting member has at least one pawl member movable between an active position where the pawl member allows transmission of rotary power from the hub shell to the power transmitting member and an inactive position decoupling the pawl from one of the power transmitting member and the hub shell. A one way roller clutch assembly is coupled between the power transmitting member and the hub shell and is movable between an active position where the roller clutch assembly couples the power transmitting member to the hub shell to transmit rotary power from the power transmitting member to the hub shell and an inactive position decoupling the power transmitting member from the hub shell.
