Abstract
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.
Claims20
A bicycle comprising:
- a frame including:
- a head tube;
- a stem pivotally coupled to the head tube;
- a down tube having a first end coupled to the head tube and an opposing second end, the down tube extending rearward from the head tube at a downward angle;
- a central portion positioned at the opposing second end of the down tube and extending substantially horizontally therefrom, the central portion defining a cavity and including a mount;
- and
- chain stays extending rearward from the central portion, the chain stays defining recesses at rear ends thereof;
- wherein an upper surface of the central portion and the down tube defines an opening that provides access to the cavity;
- a motor coupled to the mount;
- a battery releasably received within at least a portion of the frame, the battery configured to power the motor;
- a crank set coupled to the motor, the crank set including crank arms;
- a cover extending over the opening to enclose the cavity;
- and
- a lighting system connected to the battery with wires extending internally through the frame, the lighting system including:
- a conspicuity lamp integrated into the head tube;
- a headlight coupled to the stem such that a direction of illumination of the headlight is variable relative to the head tube and the conspicuity lamp;
- and
- taillights disposed within the recesses of the chain stays, wherein the taillights are positioned along a rear surface and a side surface of the chain stays.

An electric bicycle comprising:
- a frame defining a cavity, a first opening providing access to the cavity, an interior compartment, and a second opening providing access to the interior compartment, the frame including a mount extending at least partially directly underneath the cavity;
- a motor coupled to the mount and, therefore, positioned at least partially underneath the cavity;
- a battery extending at least partially into the frame, the battery configured to power the motor;
- a first key interface supported by the mount and facing laterally outward therefrom, wherein turning a key in the first key interface releases the battery to facilitate removing the battery from the frame;
- a crank set coupled to the motor, the crank set including crank arms;
- a shell extending at least partially over the first opening;
- a door pivotally coupled to the frame and extending across the second opening;
- and
- a second key interface positioned along the frame proximate the door, wherein turning a key in the second key interface unlocks the door to facilitate accessing the interior compartment.

An electric bicycle comprising:
- a frame including:
- a head tube;
- a stem pivotally coupled to the head tube;
- a down tube having a first end coupled to the head tube and an opposing second end, the down tube extending rearward from the head tube at a downward angle;
- a central portion positioned at the opposing second end of the down tube and extending substantially horizontally therefrom, the central portion defining a cavity and including a mount positioned at least partially directly underneath the cavity, an upper surface of the central portion and the down tube defining a first opening that provides access to the cavity, the upper surface of the downtube defining a second opening;
- chain stays extending rearward from the central portion;
- and
- a seat tube extending upward from and proximate an interface between the central portion and the chain stays;
- a motor coupled to the mount and, therefore, the motor is positioned at least partially underneath the cavity;
- a battery extending at least partially into the cavity and positioned directly above the motor, the battery configured to power the motor, wherein the mount supports the motor and the battery;
- a key interface supported by the mount and facing laterally outward therefrom, wherein turning a key in the key interface releases the battery to facilitate removing the battery from the frame;
- a crank set coupled to the motor, the crank set including crank arms;
- a cover extending over the first opening to at least partially enclose the cavity, the cover having an exterior surface with a first portion extending along the down tube and a second portion extending along the central portion such that the first portion is angled relative to the second portion and substantially matches a curved profile of a transition of the frame between the down tube and the central portion along the upper surface;
- and
- a storage compartment including:
- a door pivotally coupled to the down tube and positioned to selectively enclose the second opening;
- and
- a receptacle disposed within an interior of the downtube and positioned beneath the second opening.
