Abstract: The present disclosure relates to electric road-legal vehicles, and provides a pedal-assisted RTO registrable two-wheeled electric vehicle (20). The vehicle (20) includes a hub motor (8) mounted on its rear wheel (9) axle, and a pedal assembly (6). The vehicle (20) houses a battery pack (2), and a swing arm. The battery pack (2) drives the hub motor (8) at power greater than 250 Watts and top speed greater than 25 kmph. A sensing unit senses the angular displacement of an accelerator (1) to generate a sensed displacement value. A torque sensor (7) is fitted in the frame near the pedals, to sense the torque applied by the pedal assembly (6) while driving, and generate a sensed torque value. A control module receives the sensed displacement value and the sensed torque value to generate an actuating signal for supplying power from the battery pack (2) to drive the hub motor (8).

Abstract: A bicycle chain ring having a plurality of teeth extending radially about an axis of the chain ring, the plurality of teeth including a first group of teeth and a second group of teeth. The first group of teeth has a first width at a tooth base that is sized to be received within a chain cavity defined between parallel links of a bicycle chain. The second group of teeth has a second width at the tooth base, the second width being different from the first width. Further, the first group of teeth have a tooth tip that is substantially centered on a plane defined between an inner surface and an outer surface of the chain ring and the second group of teeth is at least partially offset from the plane.

Abstract: A crank assembly comprises a crank arm, a front sprocket unit, and at least one chain-drop control protrusion. The at least one chain-drop control protrusion is configured to inhibit a drive chain from getting into a space provided radially inwardly from the at least one control protrusion and between the crank arm and the front sprocket unit in the axial direction. The at least one chain-drop control protrusion is configured to be provided to at least one of an axially inwardly facing crank-surface of the crank arm and an axially outwardly facing sprocket-surface of the front sprocket unit. The at least one chain-drop control protrusion has a through bore.

Abstract: A system and method for simple transmission of a multi-speed bicycle is provided. A bicycle can have a transmission that can be toggled by a kickback shifting mechanism. A rear wheel hub can support a freewheel having a high speed gear sprocket and a low speed gear sprocket with dedicated chains to create dedicated gear-shifting. Rotating the pedal shaft in the non-drive direction approximately one-quarter rotation can toggle the transmission between the first gear ratio and the second gear ratio with a shifting surface that alternately allows driving engagement of the high speed gear sprocket with the rear wheel driver.

Abstract: A drive train for a human-powered vehicle comprises a drive unit, a sprocket arrangement, and a total gear range quotient. The drive unit includes a motor configured to impart propulsion to the human-powered vehicle. The sprocket arrangement is operatively coupled to the drive unit. The sprocket arrangement comprises a plurality of rear sprockets and a plurality of gear ratios respectively corresponding to the plurality of rear sprockets. The plurality of gear ratios includes a largest gear ratio and a smallest gear ratio. The total gear range quotient is obtained by dividing the largest gear ratio by the smallest gear ratio. The total gear range quotient is larger than 5.

Abstract: 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.

Abstract: A balanced motorcycle powertrain is described. Embodiments of the balanced motorcycle powertrain include components mounted to a frame of a motorcycle such that the powertrain can be evenly balanced about a centerline of the frame. The balanced motorcycle powertrain can include, but is not limited to, a motor, a transmission, a pair of clutches, a clutch shaft, a crank shaft, a pair of superchargers, a pair of chains, a pair of rear sprockets, and a rear wheel. Each of the components can be oriented such that the powertrain is substantially balanced about the centerline of the frame.

Abstract: The present invention is a chain structure of bicycles, which comprises a plurality of rollers, a plurality of chain sheets and a plurality of chain rollers. Wherein the rollers define a mounting space. Each chain sheet comprises a chain body, a first pivot joint part extending from one end of chain body and to be arranged in the mounting space, a second pivot joint part horizontally extending from the other end of chain body, the second pivot joint part is installed on the roller with the first pivot joint part, wherein the first pivot joint part is in a horizontal position different from chain body, the first pivot joint part defines a rotation space for placing the second pivot joint part of another chain sheet, so that the first pivot joint part and second pivot joint part can rotate a preset angle in the rotation space. When the chain sheets are combined with rollers respectively, the chain bodies remain on the same plane, the chain roller penetrates the second pivot joint part and the first pivot joint part respectively for connecting the roller to the chain sheets on both sides of roller. Thereby, the chain is thinned and the weight is reduced, the tensile strength is increased by thickening the chain sheet.
