Step 3Make the Generator Motor Mount
The motor mount is spring loaded and the friction wheel rides on the braking surface of the rim. This works much better than my original Bike Generator which tended to bounce around on the tire while riding. I also got different tires which wouldn't work well that set up because the have tread vs. the smooth tires I had.
The 3/4" aluminum angle was made to mount to the motor The 1-1/4" aluminum was made to mount to the rack. These two parts are connected together by the two #6-32 machine screws and the two spring. The screws thread into the tapped holes on the motor mount with the springs around them. This allows for the motor to move with the rim as you ride. This ensures that the generator wheel is always in contact with rim. The #6-32 all-thread was used to make two U-bolts. They fit the size of the bars on the rack.
I have included two drawings in the pdf for the two brackets I made to mount the motor. I also created an assembly drawing of the motor, wheel, and brackets. You will need to download the freeeDrawings Viewer to view the drawing.
