Abstract

An ebike comprises a front wheel, a rear wheel, and a frame structure supported on the front wheel and the rear wheel. The frame structure includes a main frame having a bottom shell coupling a down tube to a seat tube. The bottom shell at least partially defines a hollow interior. The motor assembly has an upper motor portion positioned in the hollow interior and a lower motor portion hanging below the bottom shell, and the battery assembly is at least partially positioned in the hollow interior, and the battery assembly includes a lower battery portion hanging below the bottom shell. The frame structure may also include a rear frame pivotally coupled to the main frame at a lower pivot axis defining a horizontal plane. The motor assembly may be secured to the bottom shell by a lower fastener below the horizontal plane and an upper fastener above the horizontal plane.

First claim

1 . An ebike comprising:
a front wheel; a rear wheel; a frame structure supported on the front wheel and the rear wheel, the frame structure including a main frame and further including a rear frame pivotally coupled to the main frame at a lower pivot axis defining a horizontal plane, wherein the main frame includes a head tube, a down tube, a seat tube, and a bottom shell coupling the down tube to the seat tube, the bottom shell including sidewalls at least partially defining a hollow interior; and a motor assembly having an upper motor portion positioned in the hollow interior of the bottom shell and a lower motor portion hanging below the bottom shell, the motor assembly being secured to the bottom shell by a lower fastener below the horizontal plane and an upper fastener above the horizontal plane.

2 . An ebike as claimed in claim 1 , wherein the bottom shell includes a downwardly facing opening at least partially defined by lower edges of the sidewalls.

3 . An ebike as claimed in claim 1 , further comprising a battery assembly at least partially positioned in the hollow interior of the bottom shell, the battery assembly including a lower battery portion hanging below the bottom shell.

4 . An ebike as claimed in claim 3 , wherein the down tube defines a down tube axis, and wherein the battery assembly is slidable from the bottom shell along a battery axis that is parallel to the down tube axis when the motor assembly is secured to the bottom shell.

5 . An ebike as claimed in claim 3 , wherein the lower motor portion and the lower battery portion are positioned lower than the main frame.

6 . An ebike as claimed in claim 3 , wherein the lower motor portion and the lower battery portion are positioned lower than the rear frame.

7 . An ebike as claimed in claim 3 , wherein each one of the battery assembly and the motor assembly is able to be removed from the main frame without another one of the battery assembly and motor assembly being removed from the main frame.

8 . An ebike as claimed in claim 1 , wherein no portion of the main frame is positioned below the motor assembly, and wherein the ebike further comprises a motor cover enclosing the lower motor portion.

9 . An ebike comprising:
a front wheel; a rear wheel; a frame structure supported on the front wheel and the rear wheel, the frame structure including a main frame having a head tube, a down tube, a seat tube, and a bottom shell coupling the down tube to the seat tube, the bottom shell including sidewalls at least partially defining a hollow interior; a motor assembly having an upper motor portion positioned in the hollow interior of the bottom shell and a lower motor portion hanging below the bottom shell; and a battery assembly at least partially positioned in the hollow interior of the bottom shell, the battery assembly including a lower battery portion hanging below the bottom shell.

10 . An ebike as claimed in claim 9 , wherein the lower motor portion and the lower battery portion are positioned lower than the main frame.

11 . An ebike as claimed in claim 9 , wherein the lower motor portion and the lower battery portion are positioned lower than the rear frame.

12 . An ebike as claimed in claim 9 , wherein each one of the battery assembly and the motor assembly is able to be removed from the main frame without another one of the battery assembly and motor assembly being removed from the main frame.

13 . An ebike as claimed in claim 9 , wherein the down tube defines a down tube axis, and wherein the battery assembly is slidable from the bottom shell along a battery axis that is parallel to the down tube axis when the motor assembly is secured to the bottom shell.

14 . An ebike as claimed in claim 9 , wherein no portion of the main frame is positioned below the motor assembly, and wherein the ebike further comprises a motor cover enclosing the lower motor portion.

15 . An ebike frame assembly comprising:
a frame structure adapted to be supported on a front wheel and the rear wheel, the frame structure including a main frame having a head tube, a down tube, a seat tube, and a bottom shell coupling the down tube to the seat tube, the bottom shell including sidewalls at least partially defining a hollow interior; a motor assembly having an upper motor portion positioned in the hollow interior of the bottom shell and a lower motor portion hanging below the bottom shell; and a battery assembly at least partially positioned in the hollow interior of the bottom shell, the battery assembly including a lower battery portion hanging below the bottom shell.

16 . An ebike frame assembly as claimed in claim 15 , wherein the lower motor portion and the lower battery portion are positioned lower than the main frame when the frame structure is supported on a front wheel and a rear wheel.

17 . An ebike frame assembly as claimed in claim 15 , wherein the frame structure further includes a rear frame coupled to the main frame, and wherein the lower motor portion and the lower battery portion are positioned lower than the rear frame when the frame structure is supported on a front wheel and a rear wheel.

18 . An ebike frame assembly as claimed in claim 15 , wherein each one of the battery assembly and the motor assembly is able to be removed from the main frame without another one of the battery assembly and motor assembly being removed from the main frame.

19 . An ebike frame assembly as claimed in claim 15 , wherein the down tube defines a down tube axis, and wherein the battery assembly is slidable from the bottom shell along a battery axis that is parallel to the down tube axis when the motor assembly is secured to the bottom shell.

20 . An ebike frame assembly as claimed in claim 15 , wherein no portion of the main frame is positioned below the motor assembly when the frame structure is supported on a front wheel and a rear wheel, and wherein the ebike frame assembly further comprises a motor cover enclosing the lower motor portion.
