A continuously variable transmission (CVT) having a main shaft configured to support and position various components of the CVT. Shift cam discs cooperate with ball-leg assemblies to shift the transmission ration of the CVT. Load cam discs, a torsion disc, rolling elements, and a hub cap shell are configured to generate axial force, transmit torque, and manage reaction forces. In one embodiment, a splined input shaft and a torsion disc having a splined bore cooperate to input torque into the variator of the CVT. Among other things, various ball axles, axle-ball combinations, and reaction force grounding configurations are disclosed. In one embodiment, a CVT having axial force generation means at both the input and output elements is disclosed.

A scooter includes a scooter body with substantially triangular front and rear body portions. The substantially triangular front body portion has a front side and a first connecting side. The front side and the first connecting side of the front body portion form a first acute angle. The substantially triangular rear body portion has a rear side and a second connecting side. The rear side and the second connecting side of the rear body portion form a second acute angle. The first and the second connecting sides are connected so as to linearly slide with respect to one another such that when the scooter body is in an extended state the front side is in a greater distance from the rear side than a distance when the scooter body is in a compact state.

A pedal-electric bicycle utilizes an e-clutch to prevent a motor of the pedal-electric bicycle that is fixedly engaged to a drivetrain of the pedal-electric bicycle from resisting movement of the drivetrain when the motor is not transferring power to the drivetrain. The e-clutch causes the motor to operate at a minimum torque level to overcome the internal resistance thereof. The use of an e-clutch beneficially permits the elimination of a mechanical motor clutch, thus reducing complexity, cost, and weight of the pedal-electric bicycle.

The present invention provides a rotation transmission mechanism including an internal rotation member and an external rotation member rotatably arranged with respect to the internal rotation member. The internal rotation member has one or a plurality of outer-peripheral-projected portions protruding toward an outer-peripheral side. The external rotation member has one or a plurality of inner-peripheral-projected portions. The outer-peripheral-projected portions have a forward-movement surface located at a position displaced from a center of the outer-peripheral-projected portion in a forward movement direction in which the rotation transmission mechanism rotates by forward movement. An elastically-deformable portion is disposed between the forward-movement surface and the inner-peripheral-projected portion. A space is partially formed in the elastically-deformable portion. When the internal rotation member rotates relative to the external rotation member, the elastically-deformable portion is sandwiched between the outer-peripheral-projected portion and the inner-peripheral-projected portion and is thereby elastically deformed.
