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.

A human-powered vehicle control device includes an electronic controller and a first operating portion. The first operating portion operates a human-powered vehicle device. The electronic controller controls a supply of electric power from a battery to the human-powered vehicle device in a first mode. The electronic controller controls the electric power supplied from the battery to the human-powered vehicle device in a second mode to be less than the electric power supplied in the first mode. The electronic controller switches the first mode to the second mode upon determining the first operating portion has been operated by a first action while in the first mode. The electronic controller does not switch from the second mode to the first mode upon determining the first operating portion has been operated by the first action while in the second mode.

A bicycle includes a frame, a motor, a battery, a key interface, a crank set, and a shell. The frame defines a cavity and an opening providing access to the cavity. The motor is coupled to frame beneath the cavity. The battery extends at least partially into the frame. The battery is configured to power the motor. The key interface is positioned along an exterior of the frame. Turning a key in the key interface releases the battery to facilitate removing the battery from the frame. The crank set is coupled to the motor. The crank set includes crank arms. The shell extends at least partially over the opening.

A handlebar grip set has two turn signals, two operating kits, and two grips. Each of the two turn signals is detachable and has a base, an illumination module assembled to the base, and a housing assembled to the base and covering the illumination module. Each operating kit has a button module electrically connected to the illumination module of a corresponding one of the turn signals. Each one of the grips surrounds the base of a corresponding one of the turn signals. The base of each turn signal is configured to be assembled to one of two ends of a handlebar. The turn signals of the handlebar grip set provide sufficient warning function when a bicycle equipped with the handlebar grip set is turning.
