Integrated folding bike system

1. A product comprising:

a bicycle with an integrated folding system comprising:

a first latch system in a stem of the bicycle;

a second latch system in a headset of the bicycle;

a third latch system in a frame of the bicycle;

a handle constructed and arranged so that pulling the handle upward activates the first latch system, the second latch system, and the third latch system; and

wherein the first latch system, the second latch system, and the third latch system work simultaneously to fold the bicycle to a compact size.

2. The product of claim 1 wherein the bicycle is constructed and arranged so that when it is folded to the compact size, the bicycle can be rolled by the handle or carried by the handle.

3. The product of claim 1 wherein the first latch system is constructed and arranged so that when the first latch system is activated, a first handle bar and a second handle bar fold backward and toward each other.

4. The product of claim 1 wherein the second latch system is constructed and arranged so that when the second latch system is activated, a steerer tube folds backward and toward the frame of the bicycle.

5. The product of claim 1 wherein the third latch system is constructed and arranged so that when the third latch system is activated, a hinge in the frame folds open causing the frame to fold.

6. The product of claim 1 wherein the frame is constructed and arranged to conceal at least one cable.

7. The product of claim 4 wherein the steerer tube is constructed and arranged to lock into a folded position.

8. The product of claim 4 wherein the steerer tube is constructed and arranged to rotate at an angle in a folded position.

9. The product of claim 8 wherein the steerer tube is constructed and arranged to lock at the angle in the folded position.

10. The product of claim 1 wherein the first latch system includes a knuckle joint.

11. The product of claim 10 wherein the knuckle joint comprises a stem, a first handle bar and a second handle bar rotatably attached to the stem; a shear pin, wherein the shear pin is constructed and arranged to extend through the stem in an unfolded position to lock the first handle bar and the second handle bar in the unfolded position and wherein in a folded position, the shear pin is lifted out from the stem causing the first handle bar and the second handle bar to rotate backward and toward each other.

12. The product of claim 1 wherein the second latch system comprises a hinge feature in the steerer tube.

13. The product of claim 12 wherein

the steerer tube comprises an upper shaft and a lower shaft pivotally attached to each other;

an upper frame member moveably attached to the upper shaft;

a lower frame member attached to the frame; and

wherein the second latch system is constructed and arranged so that when the second latch system is activated, the upper frame member is lifted upward which allows the upper shaft to pivot downward approximately perpendicular to the lower shaft in a folded position.

14. The product of claim 13 wherein the lower shaft further comprises a spring-loaded lock pin, wherein the spring-loaded lock pin is constructed and arranged so that in the folded position the spring-loaded lock pin engages an opening in the upper shaft and locks the steerer tube in the folded position, and wherein when the spring-loaded lock pin is pushed downward, the spring-loaded lock pin is removed from the opening so that the upper shaft is unlocked from the folded position.

15. The product of claim 14 wherein the lower shaft further comprises a spring-loaded shaft collar with a collar pin operatively connected to the spring-loaded lock pin, wherein the spring-loaded shaft collar includes a groove constructed and arranged to accommodate an angle lock pin extending from the lower frame member so that when the bicycle is in an unfolded position, the spring-loaded shaft collar is pushed downward from the spring-loaded lock pin so that the angle lock pin is not engaged in the groove and wherein in a folded position the spring-loaded collar is pushed upward so that the angle lock pin is seated in the groove so that the steerer tube is locked into place.

16. The product of claim 1 wherein the third latch system includes a main hinge feature in the frame.

17. The product of claim 16 wherein the main hinge feature comprises:

a first frame component and a second frame component, wherein the first frame component and the second frame component are pivotally attached to each other;

a cable which extends through the frame, wherein a first end of the cable is attached to a steerer tube and a second end is attached to a spring-loaded latch pin; and

wherein in an unfolded position the spring-loaded latch pin extends between the first frame component and the second frame component which holds the frame together in an unfolded position, and wherein the spring-loaded latch pin is constructed and arranged so that when the third latch system is activated, the cable is lifted upward which pulls the spring-loaded latch pin out of the second frame component so that the frame folds together to a folded position.

18. The product of claim 17 wherein the main hinge feature further comprises a spring which is constructed and arranged to fold the frame together when the third latch system is activated.

19. A method comprising:

folding a bicycle comprising:

integrating a bicycle with a first latch system, a second latch system, and a third latch system;

lowering a seat from a raised position to a lowered position;

pulling on a handle on a steerer tube to activate the first latch system, the second latch system, and the third latch system;

wherein activating the first latch system causes a first handle bar and a second handle bar to rotate backwards;

wherein activating the second latch system allows a steerer tube to fold downward toward a frame;

wherein activating the third latch system causes the frame to fold; and

wherein the first latch system, the second latch system, and the third latch system work simultaneously to fold the bicycle.
