Abstract

A bicycle assembly comprises a saddle adjustment assembly, the saddle adjustment assembly comprising an adjustable height saddle post, the adjustable height saddle post comprising first and second slidably coupled supports; a saddle post locking mechanism that selectively restricts sliding of the second support relative to the first support; and a saddle angle adjustment mechanism configured to couple to a bicycle saddle to enable rotation of the bicycle saddle between a first predetermined position and a second predetermined position, wherein, when the saddle post locking mechanism is in an unlocked configuration, the saddle angle adjustment mechanism enables rotation of the bicycle saddle between the first and second predetermined positions, and wherein, when the saddle post locking mechanism is in a locked configuration, the saddle angle adjustment mechanism maintains the bicycle saddle in one of the first and second predetermined positions.

First claim

What is claimed is:

1. A bicycle assembly comprising an adjustable saddle system, the adjustable saddle system comprising:
a saddle angle adjustment mechanism configured to be coupled to an adjustable height saddle post and a bicycle saddle and configured to rotate the bicycle saddle with respect to the adjustable height saddle post, the saddle angle adjustment mechanism comprising:
a saddle post position sensor configured to detect a position of the adjustable height saddle post; and
a motor configured to cause powered rotation of the saddle with respect to the adjustable height saddle post; and

a saddle angle controller that controls operation of the motor to cause the powered rotation of the saddle based at least partially on a signal received from the saddle post position sensor.

2. The bicycle assembly of claim 1 , wherein the saddle post position sensor comprises an electronic sensor that generates an output proportional to a current position of the adjustable height saddle post.

3. The bicycle assembly of claim 2 , wherein the saddle angle controller is configured to control operation of the motor to cause rotation of the saddle to a predetermined rotational position based on the current position of the adjustable height saddle post.

4. The bicycle assembly of claim 1 , wherein the saddle post position sensor comprises a limit switch that detects when the adjustable height saddle post is at a predetermined position.

5. The bicycle assembly of claim 1 , wherein the saddle angle controller is configured to control operation of the motor to cause rotation of the saddle in response to the saddle post position sensor indicating to the saddle angle controller that the adjustable height saddle post is in a predetermined position.

6. The bicycle assembly of claim 1 , further comprising a saddle angle sensor configured to detect a rotational position of the saddle.

7. The bicycle assembly of claim 6 , wherein the saddle angle sensor comprises an electronic sensor that generates an output proportional to a current angle of the saddle.

8. The bicycle assembly of claim 6 , wherein the saddle angle sensor comprises a limit switch that detects when the saddle is at a predetermined angle.

9. The bicycle assembly of claim 1 , further comprising a locking mechanism controlled by the saddle angle controller, wherein the locking mechanism selectively restricts rotational motion of the saddle with respect to the adjustable height saddle post.

10. The bicycle assembly of claim 1 , wherein the saddle angle controller enables on-demand rotation of the saddle in response to activation of a rider-operatable switch.

11. The bicycle assembly of claim 1 , further comprising:
a rider presence sensor configured to detect a force of a rider applied to the bicycle saddle,
wherein the saddle angle controller is configured to activate the motor to cause rotation of the saddle based at least in part on an indication by the rider presence sensor that the bicycle saddle is not presently supporting the rider.

12. The bicycle assembly of claim 1 , further comprising:
a frame orientation sensor configured to detect an angle of a frame of the bicycle assembly with respect to a riding environment,
wherein the saddle angle controller is configured to activate the motor to cause rotation of the saddle based at least in part on an indication by the frame orientation sensor that the frame is currently at or exceeding a predetermined angle with respect to the riding environment.

13. The bicycle assembly of claim 1 , further comprising the adjustable height saddle post.

14. The bicycle assembly of claim 13 , further comprising a bicycle frame, wherein the adjustable height saddle post is coupled to the bicycle frame.

15. A bicycle assembly comprising an adjustable saddle system, the adjustable saddle system comprising:
a housing one of (1) coupled to and (2) integrated into an adjustable height saddle post;
a saddle support configured to couple to a bicycle saddle, the saddle support rotatably coupled to the housing such that rotation of the saddle support adjusts an angle of the bicycle saddle with respect to the adjustable height saddle post;
a motor comprising an output member, the output member coupled to the saddle support such that rotational motion of the output member is converted into rotational motion of the saddle support to adjust the angle of the bicycle saddle with respect to the adjustable height saddle post;
a saddle post position sensor configured to detect a position of the adjustable height saddle post; and
a saddle angle controller configured to control operation of the motor to adjust the angle of the bicycle saddle based at least partially on a signal received from the saddle post position sensor.

16. The bicycle assembly of claim 15 , wherein the saddle post position sensor comprises an electronic sensor that generates an output proportional to a current position of the adjustable height saddle post.

17. The bicycle assembly of claim 16 , wherein the saddle angle controller is configured to control operation of the motor to cause rotation of the saddle to a predetermined rotational position based on the current position of the adjustable height saddle post.

18. The bicycle assembly of claim 15 , wherein the saddle post position sensor comprises a limit switch that detects when the adjustable height saddle post is at a predetermined position.

19. The bicycle assembly of claim 15 , wherein the output member is coupled to the saddle support through a power transmission mechanism that produces a mechanical advantage.

20. The bicycle assembly of claim 15 , further comprising a saddle angle sensor configured to detect a rotational position of the saddle.
