Abstract

A foldable bicycle includes a frame, a front wheel assembly, and a rear wheel assembly. The frame defines a pivot axis. The front wheel assembly is disposed on the frame and configured to rotate about the pivot axis. The rear wheel assembly is disposed on the frame and defines an opening for receiving the front wheel assembly when the bicycle is folded.

First claim

The invention claimed is:

1. A foldable bicycle comprising:
a frame defining a pivot axis and a pivot and locking mechanism that includes a base, a locking housing that receives the base, and a pivot housing;
a front wheel assembly disposed on the frame and configured to rotate about the pivot axis; and
a rear wheel assembly disposed on the frame and defining an opening,
wherein the front wheel assembly is disposed within the opening defined by the rear wheel assembly when the bicycle is in a folded position,
wherein the pivot housing and the base engage the locking housing when the bicycle is in the folded position and in an unfolded position,
wherein the base defines holes and wherein the locking housing includes pins configured to engage the holes of the base.

2. The foldable bicycle of claim 1 , wherein the pivot axis is defined by the pivot and locking mechanism.

3. The foldable bicycle of claim 1 , wherein the pivot and locking mechanism is configured to lock the bicycle in at least one of the folded position and the unfolded position.

4. The foldable bicycle of claim 1 , wherein the pivot and locking mechanism includes a shaft disposed on the base.

5. The foldable bicycle of claim 4 , wherein the shaft extends from the pivot housing and into the locking housing.

6. The foldable bicycle of claim 4 , wherein the pivot and locking mechanism includes a spring configured to bias the base toward the locking housing.

7. The foldable bicycle of claim 6 , wherein the spring is coaxially aligned with the shaft.

8. The foldable bicycle of claim 6 , wherein the spring is substantially parallel to the shaft.

9. The foldable bicycle of claim 1 , wherein the front wheel assembly includes:
a front wheel;
a hub disposed within the front wheel; and
a motor operably connected to the hub.

10. The foldable bicycle of claim 9 , wherein a diameter of the opening defined by the rear wheel assembly is larger than an outer diameter of the front wheel.

11. The foldable bicycle of claim 1 , wherein the rear wheel assembly includes a spokeless rear wheel rotatably connected to the frame, wherein the opening is defined by the rear wheel.

12. A foldable bicycle comprising:
a frame having a pivot and locking mechanism including a base, a pivot housing, and a locking housing that receives the base, wherein the pivot housing defines a pivot axis and wherein the locking housing is configured to lock the frame into at least one of a folded position and an unfolded position;
a front wheel assembly disposed on the frame and configured to rotate about the pivot axis; and
a rear wheel assembly disposed on the frame and defining an opening having a diameter larger than an outer diameter of the front wheel assembly,
wherein the front wheel assembly is disposed within the opening defined by the rear wheel assembly when the bicycle is in a folded position,
wherein the pivot housing and the base engage the locking housing when the bicycle is in the folded position and in the unfolded position,
wherein the base defines holes and wherein the locking housing includes pins configured to engage the holes of the base.

13. The foldable bicycle of claim 12 , wherein the pivot and locking mechanism includes a shaft disposed on the base and extending from the pivot housing into the locking housing.

14. The foldable bicycle of claim 13 , wherein the pivot and locking mechanism includes a spring configured to bias the base toward the locking housing.

15. The foldable bicycle of claim 12 , wherein the rear wheel assembly includes a spokeless rear wheel rotatably connected to the frame, wherein the opening is defined by the rear wheel.
