  • Patent number: 11912080
    Abstract: A hitch system for automatically coupling a hitch accessory that has an attachment bar assembly with a hitch receiver. The attachment bar assembly includes a housing bar that is tubular, with a pin-hole through the housing bar. A pin-lever is pivotably mounted in the housing bar and includes a pin configured to retract into the housing bar and to extend out of the pin-hole. A ramp-component is disposed in the housing bar and is engageable with the pin-lever. An actuator selectively moves the ramp-component to retract the pin into the housing bar and to extend the pin out of the housing bar, by selectively enabling pivoting of the pin-lever.

  • Publication number: 20210114686
    Abstract: A vehicle includes a road wheel and a crank configured to receive operator torque and provide crank power to the road wheel. A torque sensor is operatively coupled to the crank and configured to detect operator torque at the crank. A cadence sensor is operatively coupled to the crank and configured to detect a rotational speed of the crank. A motor is drivingly coupled to the road wheel and configured to selectively provide motor power to the road wheel. A controller is configured to control the motor power based on a target wheel speed of the road wheel. The controller is further configured to establish the target wheel speed based on the operator torque in response to the rotational speed being below a predefined threshold and to establish the target wheel speed based on the rotational speed in response to the rotational speed being at or above the predefined threshold.

  • Publication number: 20190291807
    Abstract: A cycle includes a foldable frame having a hinge between a fore portion and an aft portion. The frame is movable between folded and unfolded positions. A front fork with a first central axis is pivotably coupled to the fore portion. A handlebar stem with a second central axis is rotatably and slidably coupled to the front fork. The second central axis is non-coaxial with the first central axis. A seat post is slidably coupled to the aft portion. The fore portion has first and second apertures therethrough. When the frame is in the folded position, the handlebar stem may be disposed at least partially within the first aperture to thereby secure the front fork relative to the frame, and the seat post may be disposed at least partially within the second aperture to thereby secure the frame in the folded position.

  • Patent number: 10286973
    Abstract: A product may include a pair of handles that may be foldable. A wedge may be engaged between the pair of handles and may lock the pair of handles in a first position. A release mechanism may be connected to the wedge. Operation of the release mechanism may move the wedge to disengage from and to unlock the handles and may enable moving the pair of handles to a folded position.

  • Patent number: 10112674
    Abstract: A product may include a steering tube that may have a first component, and a second component. A hinge may be connected to enable the first and second components to fold relative to one another so that the steering tube is foldable. A latch may secure the first and second components in an unfolded position. The first and second components may be locked in a folded position. The latch may include a lever that has a latch hook. The first and second components may be secured through engagement of the latch hook with a striker.
