Electric bicycle

A bicycle comprising:

• a frame including:
• a head tube;
• a stem pivotally coupled to the head tube;
• a down tube coupled to the head tube, the down tube defining a compartment opening;
• a central hub coupled to the down tube opposite the head tube, the central hub defining an internal cavity, and the down tube and the central hub cooperatively defining a battery opening connected to the internal cavity;
• and
• a pair of chain stays extending rearward of the central hub, the pair of chain stays including (i) a right chain stay terminating with a right dropout and (ii) a left chain stay terminating with a left dropout, wherein the right dropout defines a right recess and the left dropout defines a left recess;
• a storage compartment including:
• a door pivotally coupled to the down tube and positioned to selectively enclose the compartment opening;
• and
• a receptacle disposed within the interior of the frame and positioned beneath the compartment opening;
• a battery pack releasably received by the battery opening and at least partially recessed within the internal cavity of the central hub;
• a pedal assist unit disposed within the internal cavity of the central hub and powered by the battery pack;
• and
• a lighting system connected to the battery pack with wires extending internally through the frame, the lighting system including:
• a right taillight disposed within the right recess;
• a left taillight disposed within the left recess;
• a conspicuity lamp integrated into the head tube;
• and
• a headlight
• wherein the headlight provides more illumination than the conspicuity lamp;
• wherein a direction of illumination of the conspicuity lamp is stationary relative to the head tube;
• and
• wherein a direction of illumination of the headlight is variable relative to the head tube.

A bicycle comprising:

• a frame including:
• a head tube;
• a down tube coupled to the head tube;
• a central hub coupled to an end of the down tube opposite the head tube, the central hub defining an internal cavity and including a mount positioned at least partially directly underneath the internal cavity, an upper surface of the down tube and the central hub cooperatively defining an opening connected and providing access to the internal cavity;
• and
• a pair of chain stays extending rearward of the central hub, the pair of chain stays including (i) a right chain stay terminating with a right dropout and (ii) a left chain stay terminating with a left dropout;
• a motor coupled to the mount such that the motor is positioned at least partially underneath the internal cavity;
• a battery pack extending at least partially into the internal cavity of the central hub and positioned at least partially directly above the motor, the battery pack configured to power the motor;
• and
• a key interface supported by the mount and facing laterally outward therefrom, wherein engaging the key interface releases the battery pack to facilitate lifting the battery pack upward to remove the battery pack from the frame.
