A pedaled drivetrain includes a drive mechanism, a wheel, a freewheel hub, and a locking mechanism. The wheel has a rotational axis. The freewheel hub connects the drive mechanism to the wheel, and the freewheel hub transmits torque from the drive mechanism to the wheel in a first rotational direction around the rotational axis. The locking mechanism has a locked state and an unlocked state. The locked state rotationally fixes a component of the drive mechanism to the wheel relative to the rotational axis.

A clutch apparatus comprises a first race, a second race arranged coaxial with and rotatable relative to the first race, and an engagement mechanism provided between the first race and the second race for engagement of the first race and said second race. The engagement mechanism comprising a first clutch allowing rotation of the first race in only one direction, and a second clutch arranged axially adjacent to the first clutch, the second clutch comprising a rotary member that is provided on the second race in a rotatable and axially immovable manner and a movable member that is movable in the axial direction, and a cam mechanism disposed between the rotary member and the movable member, and the movable member being engaged with the first race by being moved in the axial direction by the cam mechanism.

A clutch assembly includes an outer ring having a first and second pocket, and an inner ring. A strut and pawl may be disposed within the first and second pockets. The pawl may be configured such that rotation of the strut pushes the pawl toward teeth of the inner ring for engagement therewith. In a first mode of operation, the pawl does not contact the teeth and the inner ring is free to rotate in the first and second rotational directions. In a second mode of operation, the pawl is in partial engagement with the teeth and the inner ring is free to rotate in the second rotational direction and prevented from rotation in the first rotational direction. In a third mode of operation, the pawl is in full engagement with the teeth and the inner ring is prevented from rotation in both the first and the second rotational directions.

A two-speed drive unit of an electric vehicle includes a planetary gear set transmission having multiple elements including a first element, a second element and a third element. A motor generator unit supplies a motive force to the planetary gear set transmission. A first stage gear transfers the motive force to the planetary gear set transmission from the motor generator unit. A second stage gear is connected through the second element to a final drive. A first torque transmitting device defining a selectable one-way clutch (SOWC) is connected to the third element.
