Abstract

An ebike comprises a front wheel, a rear wheel, a frame structure supported on the front wheel and the rear wheel, a motor assembly coupled to the frame structure, and a battery assembly configured to be coupled to the frame structure. The frame structure includes a head tube, a down tube, a top tube, a seat tube, and a diagonal tube coupling the top tube with the seat tube. The battery assembly is configured to be at least partially positioned in the down tube. The ebike further includes a user interface configured to be supported by the frame structure, and further includes an electrical cable coupling the user interface with the motor assembly, the electrical cable being positioned at least partially in the diagonal tube.

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 front fork coupled to the front wheel, a head tube coupled to the front fork, a down tube extending downward and rearward from the head tube, a top tube extending rearward from the head tube, a seat tube coupling a rear end of the top tube to a rear end of the down tube, and a diagonal tube coupling the top tube with the seat tube; a motor assembly coupled to the frame structure; a battery assembly configured to be coupled to the frame structure and to be at least partially positioned in the frame structure; a user interface configured to be supported by the frame structure; and an electrical cable coupling the user interface with the motor assembly, the electrical cable being positioned at least partially in the diagonal tube.

2 . An ebike as claimed in claim 1 , wherein the rear wheel defines a center plane, and wherein the diagonal tube comprises a side tube offset from the center plane.

3 . An ebike as claimed in claim 1 , wherein the battery assembly is positioned at least partially in the down tube, and wherein an interior of the down tube is free of electrical cables.

4 . An ebike as claimed in claim 1 , wherein the down tube defines a down tube axis and includes a lower end having an opening, and wherein the battery assembly is configured to be at least partially secured in the down tube in an installed position and is configured to be slidable from the lower end of the down tube through the opening along the down tube axis.

5 . An ebike as claimed in claim 4 , wherein the battery assembly includes a lower end that protrudes from the lower end of the down tube when the batter assembly is in the installed position.

6 . An ebike as claimed in claim 5 , further comprising a crank assembly supported by the frame structure, the crank assembly being rotatable about a crank axis that is spaced rearward from the down tube axis.

7 . An ebike as claimed in claim 6 , wherein a lower battery portion of the battery assembly extends below a horizontal plane defined by the crank axis.

8 . An ebike as claimed in claim 7 , wherein the frame structure further includes a bottom shell coupling the down tube to the seat tube, the bottom shell including sidewalls at least partially defining a hollow interior, and wherein the motor assembly includes an upper motor portion positioned in the bottom shell and a lower motor portion hanging below the bottom shell.

9 . An ebike as claimed in claim 8 , wherein the lower motor portion and the lower battery portion are positioned lower than the frame structure.

10 . An ebike frame assembly comprising:
a frame structure adapted to be supported on a front wheel and a rear wheel, the frame structure including a front fork, a head tube coupled to the front fork, a down tube extending downward and rearward from the head tube, a top tube extending rearward from the head tube, a seat tube coupling a rear end of the top tube to a rear end of the down tube, and a diagonal tube coupling the top tube with the seat tube; a motor assembly coupled to the frame structure; a battery assembly configured to be coupled to the frame structure and to be at least partially positioned in the frame structure; a user interface configured to be supported by the frame structure; and an electrical cable coupling the user interface with the motor assembly, the electrical cable being positioned at least partially in the diagonal tube.

11 . An ebike as claimed in claim 10 , wherein the frame structure defines a center plane, and wherein the diagonal tube comprises a side tube offset from the center plane.

12 . An ebike as claimed in claim 10 , wherein the battery assembly is positioned at least partially in the down tube and wherein an interior of the down tube is free of electrical cables.

13 . An ebike as claimed in claim 10 , wherein the down tube defines a down tube axis and includes a lower end having an opening, and wherein the battery assembly is configured to be at least partially secured in the down tube in an installed position and is configured to be slidable from the lower end of the down tube through the opening along the down tube axis.

14 . An ebike as claimed in claim 13 , wherein the battery assembly includes a lower end that protrudes from the lower end of the down tube when the batter assembly is in the installed position.

15 . An ebike as claimed in claim 14 , further comprising a crank assembly supported by the frame structure, the crank assembly being rotatable about a crank axis that is spaced rearward from the down tube axis.

16 . An ebike as claimed in claim 15 , wherein a lower battery portion of the battery assembly extends below a horizontal plane defined by the crank axis.

17 . An ebike as claimed in claim 16 , wherein the frame structure further includes a bottom shell coupling the down tube to the seat tube, the bottom shell including sidewalls at least partially defining a hollow interior, and wherein the motor assembly includes an upper motor portion positioned in the bottom shell and a lower motor portion hanging below the bottom shell.

18 . An ebike as claimed in claim 17 , wherein the lower motor portion and the lower battery portion are positioned lower than the frame structure.
