Abstract

An e-bike includes a frame assembly, wheels supporting the frame assembly, a motor assembly coupled to the frame assembly, and a battery coupled to the frame assembly. The battery includes a battery housing and a battery mount. The e-bike further includes a fastener coupling the frame assembly to the battery mount, and a resilient pad adjacent the battery mount, the resilient pad being compressed between the frame assembly and the battery housing.

First claim

The invention claimed is:

1. An e-bike comprising:
a frame assembly;
wheels supporting the frame assembly;
a motor assembly coupled to the frame assembly;
a battery coupled to the frame assembly, the battery including a battery housing and a battery mount, wherein the battery mount is located along a side of the battery housing, wherein the battery mount defines an aperture;
a fastener extending into the aperture and coupling the frame assembly to the battery mount; and
a resilient pad located adjacent the battery mount and in contact with an exterior surface of the battery housing, wherein the resilient pad extends at least partially around the aperture and is compressed between the frame assembly and the battery housing.

2. The e-bike of claim 1 , wherein the resilient pad is disk-shaped.

3. The e-bike of claim 2 , wherein the resilient pad completely surrounds the battery mount.

4. The e-bike of claim 1 , wherein:
the battery mount is a first battery mount;
the battery further includes a second battery mount spaced apart from the first battery mount;
the resilient pad is a first resilient pad adjacent the first battery mount; and
the e-bike further includes a second resilient pad adjacent the second battery mount.

5. The e-bike of claim 4 , wherein the second resilient pad at least partially surrounds the second battery mount.

6. The e-bike of claim 4 , wherein the first resilient pad completely surrounds the first battery mount and the second resilient pad completely surrounds the second battery mount.

7. The e-bike of claim 4 , wherein the first resilient pad and the second resilient pad are positioned along a common side of the battery housing.

8. The e-bike of claim 7 , wherein only the common side of the battery housing includes resilient pads positioned along the battery housing.

9. The e-bike of claim 4 , wherein:
the battery is elongate and extends along a longitudinal axis, wherein the battery includes a first end and a second end opposite the first end and spaced from the first end along the longitudinal axis; and
the first resilient pad and the second resilient pad each are spaced away from the first end and the second end.

10. The e-bike of claim 1 , wherein the battery housing includes a housing material that is less resilient than a pad material of the resilient pad, and wherein the pad material is in direct contact with both the exterior surface of the battery housing and an interior surface of the frame assembly.

11. An e-bike comprising:
a frame assembly having an elongate frame member extending along a longitudinal axis, the elongate frame member having an open end;
wheels supporting the frame assembly;
a motor assembly coupled to the frame assembly; and
a battery positioned at least partially in the frame member, the battery including a battery housing having an engagement feature accessible from the open end of the frame member to facilitate removal of the battery through the open end of the frame member along the longitudinal axis, wherein the engagement feature is configured to receive a tool to facilitate removal of the battery from the frame member, wherein the engagement feature is an eyelet, and wherein the tool includes a hook-shaped tool.

12. The e-bike of claim 11 , wherein:
the engagement feature is integrated with the battery housing as one piece; and
the engagement feature is immovable relative to the battery housing.

13. The e-bike of claim 11 , wherein the frame member includes a downtube, and the open end includes a lower end of the downtube.

14. An e-bike battery configured to be inserted into and coupled to an e-bike frame assembly, the e-bike battery comprising:
a battery housing;
a battery mount located along a side of the battery housing, wherein the battery mount defines an aperture sized and shaped to receive a fastener; and
a resilient pad located adjacent the battery mount and in contact with an exterior surface of the battery housing, wherein the resilient pad extends at least partially around the aperture, and is configured to be compressed between the battery housing and the e-bike frame assembly when the e-bike battery is coupled to the e-bike frame assembly with the fastener.

15. The e-bike battery of claim 14 , wherein the resilient pad is disk-shaped.

16. The e-bike battery of claim 14 , wherein:
the battery mount is a first battery mount;
the e-bike battery further includes a second battery mount spaced apart from the first battery mount;
the resilient pad is a first resilient pad adjacent the first battery mount; and
the e-bike battery further includes a second resilient pad adjacent the second battery mount.

17. The e-bike battery of claim 14 , wherein the battery housing includes a housing material that is less resilient than a pad material of the resilient pad, and wherein the pad material is in direct contact with both the exterior surface of the battery housing and an interior surface of the frame assembly.

18. The e-bike battery of claim 14 , further comprising an engagement feature adjacent one end of the e-bike battery to facilitate removal of the e-bike battery from the e-bike frame assembly, wherein the engagement feature is configured to receive a tool to facilitate removal of the e-bike battery from the e-bike frame assembly.

19. The e-bike of claim 1 , wherein the aperture of the battery mount is a threaded aperture, and wherein the fastener extends through the frame assembly and into the threaded aperture to couple the frame assembly to the battery mount.

20. The e-bike battery of claim 14 , wherein the aperture of the battery mount is a threaded aperture, such that the fastener is configured to extend through the frame assembly and into the threaded aperture to couple the frame assembly to the battery mount.
