A bicycle includes a frame, a storage compartment, a battery pack, a pedal assist unit, and a lighting system. The frame includes a head tube, a stem, a down tube, a central hub, and a pair of chain stays. The central hub defines an internal cavity. The down tube and the central hub cooperatively define a battery opening connected to the internal cavity. The storage compartment includes a door positioned to selectively enclose an opening in the down tube. The battery pack is releasably received by the battery opening. The pedal assist unit is disposed within the internal cavity. The lighting system includes one or more taillights integrated into the chain stays, a conspicuity lamp integrated into the head tube, and/or a headlight integrated into to at least one of the stem or the head tube.

The present invention is generally directed to a swing arm configuration and, more specifically, a swing arm that is supported by a shaft of a motor, such as an electric motor of a motorcycle. The configuration includes a swing arm assembly that is supported by a shaft of a motor at one end and a rear axle at the other end. Advantageously, the shaft of the motor may be a structural component of an electric motorcycle and serve as the swing arm pivot as well as the drive shaft.

A riding vehicle includes: a main body supporting a wheel and on which a steering stay and a seat stay are erected at an interval in a traveling direction; a handle provided on the steering stay; a pedestal portion fixed to an upper end of the seat stay; a seat rotatably connected to the pedestal portion, and configured to switch between a riding state where the seat stands upright to cover the pedestal portion from above so as to be in an arrangement suitable for riding and a cart state where the seat is inclined in a traveling direction away from the steering stay to open an upper portion of the pedestal portion so as to be in an arrangement suitable for conveyance movement with baggage placed thereon; and a stopper interposed between the pedestal portion and the seat and regulating the seat in the riding and cart states.

A vehicle for a person to ride on a ground surface includes a frame that has a front end and a rear end. The frame supports a seat on a top side of the frame and a steering mechanism proximate the front end of the frame for allowing the person to steer a front wheel. A frame extension has a front end pivotally fixed proximate the rear end of the frame and includes two rear wheels projecting laterally away therefrom. At least one of the rear wheels is coupled with a motor through a transmission to drive the vehicle. In use, the frame extension and rear wheels are pivoted forward to place the vehicle in a collapsed configuration for storage. To use the vehicle, the frame extension is pivoted backward to place the vehicle in an operating configuration. Preferably the motor and transmission are disposed between the two rear wheels.

A bicycle includes a chainstay protector having an upper surface including a valley, a first peak, and a second peak. The first peak extends upwardly from the valley toward the chain and has a first contact surface positioned to contact the chain a first height above the valley. The second peak extends upwardly from the valley toward the chain and has a second contact surface positioned to contact the chain a second height above the valley. The first contact surface is spaced from the second contact surface by a gap that is at least 5 times the first height. Each of the first and second contact surfaces has a length that is less than the length of the gap and less than two times a pitch of the chain.
