Bicycle with battery mount

1. A bicycle comprising:

a frame including a head tube;

a fork rotationally coupled to the head tube;

a wheel rotationally coupled to the fork;

a handlebar coupled to the fork for steering the wheel;

a battery pack supported by the frame and defining a longitudinal axis, the battery pack including a powered end cap having tapered protrusion with a portion that is curved in a longitudinal cross-section and a lateral cross-section and a battery connector on an end of the tapered protrusion; and

a receiver supported by the frame and including a tapered socket in which the tapered protrusion is positioned, the tapered socket including a power connector detachably coupled to the battery connector,

wherein the battery pack has a side surface and a shoulder between the side surface and the tapered protrusion on at least one side of the battery pack, and

wherein the tapered protrusion is bull-nosed shaped with a conical portion abutting the shoulder, and the portion that is curved is disposed opposite the conical portion.

2. The bicycle of claim 1 , wherein the battery pack has a side surface and the tapered protrusion has a tapered surface that is flush with the side surface on at least one side of the battery pack.

3. A battery pack for a bicycle, the battery pack comprising:

an elongated housing adapted to support a battery; and

a powered end cap coupled to the housing and having tapered protrusion with a portion that is curved in a longitudinal cross-section and a lateral cross-section and a battery connector on an end of the tapered protrusion, the battery connector adapted to detachably couple to a power connector in the bicycle,

wherein the housing has a side surface and the tapered protrusion has a tapered surface that is flush with the side surface on at least one side of the battery pack,

wherein the battery pack has a shoulder between the side surface and the tapered protrusion on at least one side of the battery pack, and

wherein the tapered protrusion is bull-nosed shaped with a conical portion abutting the shoulder and a curved portion opposite the conical portion.

4. The battery pack of claim 3 , wherein the powered end cap supports a power switch.

5. The battery pack of claim 3 , wherein the housing has a bottle cage support.

6. The battery pack of claim 3 , wherein the battery connector has a recess on the end of the tapered protrusion.

7. The battery pack of claim 3 , wherein the battery pack defines a longitudinal axis, and wherein the tapered protrusion has a tapered surface that is curved in longitudinal cross-section.

8. A bicycle comprising:

a frame including a head tube;

a fork rotationally coupled to the head tube;

a wheel rotationally coupled to the fork;

a handlebar coupled to the fork for steering the wheel;

a battery pack supported by the frame, the battery pack including a securing end cap;

a contact plate supported by and movable relative to the frame, the contact plate including an opening and a contact surface that is biased into contact with the securing end cap; and

a latch extending through the opening and movable relative to the contact plate to secure the battery pack in the frame.

9. The bicycle of claim 8 , wherein the battery pack defines a longitudinal axis and the securing end cap includes an end surface that is oblique to the longitudinal axis.

10. The bicycle of claim 9 , wherein the contact surface is oblique to the longitudinal axis and in contact with the end surface.

11. The bicycle of claim 8 , wherein the bias force of the contact surface is adjustable.

12. The battery pack of claim 1 , wherein the tapered protrusion has a conical taper and a curved taper opposite the conical taper.

13. The battery pack of claim 3 , wherein the tapered protrusion has a conical taper and a curved taper opposite the conical taper.
