摘要： A bicycle sprocket comprises sprocket teeth. The sprocket teeth include at least one first tooth and at least one second tooth. The at least one first tooth has a first radial-tooth height. The at least one first tooth has a first chain-engaging axial width which is smaller than a first distance defined between opposed outer link plates of a bicycle chain and which is larger than a second distance defined between opposed inner link plates of the bicycle chain. The first radial-tooth height is greater than the first chain-engaging axial width. The at least one second tooth has a second radial-tooth height. The at least one second tooth has a second chain-engaging axial width which is smaller than the second distance. The second radial-tooth height is greater than the second chain-engaging axial width. The first radial-tooth height is greater than the second radial-tooth height.

The at least one first tooth has a first chain-engaging axial width which is smaller than a first distance defined between opposed outer link plates of a bicycle chain and which is larger than a second distance defined between opposed inner link plates of the bicycle chain. The at least one second tooth is adjacent to the first tooth and is disposed on a downstream side in a rotational driving direction of the bicycle sprocket. The at least one second tooth is configured to engage with inner link plates of the bicycle chain. The at least one second tooth has a second radial-tooth height. The first radial-tooth height is greater than the second radial-tooth height.

摘要： 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.

摘要： A rear suspension for a three-wheeled reverse trike includes a front lever arm pivotably affixed to a frame pivotable about a front lever arm pivot axis. A slider is translatably attached to the front lever arm. A first pushrod is pivotably connected at a first end to the slider and pivotably connected at a second end to at least one of a front upper or lower control arms for the front wheels. A rear lever arm is pivotably affixed to the frame and pivotable about a rear lever arm pivot axis, the rear lever arm extending to a rear lever arm distal end. A rod pivotably connects the front and lever arms. A first pivotable end of the rear upper control arm is pivotably connected to the rear lever arm distal end, and a second pivotable end of the rear upper control arm is pivotably connected to a rear spindle.

摘要： A transmission apparatus for a leveraged wheelchair may include a wheelchair, a driving mechanism, a driving wheels set, and a transmission wheels set. The driving mechanism has a first tube and a second tube which are pivotally connected, and with the relative movements between the first tube and the second tube, the driving wheels set can have forward or rearward rotation so as to achieve bi-direction driving effect of the wheelchair. Also, the relative movement between the first tube and the second tube is cooperated with a flexible connecting head such that a handle of the wheelchair is adapted to be forward and rearward pulled or rotated axially so to achieve the moving and turning actions of the wheelchair with one hand.

摘要： A sliding method on ice-surface aims at solve the problems of power output and poor durability and the difficulty in large-scale promotion. An ice-surface sliding tool includes a seat board, a U-shaped rod, sliding plates, H-shaped connecting frames, a pushing device, a hand-operated chain wheel and a reversing gear. One end of the upper end surface of the seat board is provided with a backrest. The U-shaped rod is provided on the side wall of the other end of the seat board. The lower end of the seat board is symmetrically provided with two sliding plates in parallel to each other. The sliding plates are connected with the lower end surface of the seat board through the H-shaped connecting frames. The pushing device is rotationally provided between the two H-shaped connecting frames. The hand-operated chain wheel is on the upper end of the U-shaped rod through a support bar.

摘要： A transmission structure for a bicycle includes two opposite transmission units. Each of the transmission units includes a linear reciprocating pedaling mechanism, a transmission module which is in transmission connection with the linear reciprocating pedaling mechanism, and a resetting module connected with the transmission module. The transmission modules of the two transmission units are connected with a power output mechanism through a unidirectional transmission mechanism. The transmission module includes a first driven wheel and a first transmission gear configured to be coaxial with the first driven wheel. The resetting module includes a connecting piece and an elastic piece. The connecting piece is connected with the first transmission gear. The elastic piece is connected with the connecting piece.
