This article outlines the steps to transfer or replace the freewheel and brake rotor on the Revv 1 once the rear wheel is removed. If you haven't removed the rear wheel yet, please visit Revv 1 Rear Wheel Removal.

Step 1: Remove Brake Rotor

Remove the brake rotor first to prevent damage. There are 6 T25 (Torx) bolts holding it on.

Slide the rotor up and off, being careful with the motor cable and avoiding contact with the braking surface.

Note the rotor orientation: the side with writing faces outward. Eyelets circled in red are flush outward and slightly protrude on the wheel-facing side.

Step 2: Remove Washer from the Old Wheel

Remove this washer and set it aside; it is located further back inside the freewheel and is easy to miss.

Step 3: Remove the Freewheel

You will need a "Shimano style" freewheel removal tool. We recommend the Park Tool FR1.3. Use an adjustable wrench or 1" socket to turn counterclockwise, bracing the wheel on the ground for leverage.

Step 4: Remove Spacers

Remove the two spacers beneath the freewheel. Remember the positions: the thicker spacer rests closest to the freewheel.

Step 5: Reinstall Freewheel

Reinstalling the freewheel is similar to removal. Grease the new part (or clean and regrease if transferring/maintaining). Any automotive grease will work.

Install Spacers

Grease Threads of the Freewheel

If using a torque wrench, tighten to 40nm. If you don't have a torque wrench available, tighten until the wrench doesn't turn anymore (use moderate-firm pressure). Replace the washer from Step 2.

Step 6: Reinstall Brake Rotor

You will want to tighten the bolts in a cross pattern so that every bolt gets equal torque.

Start with #1 and go in the above order. Insert all bolts until they're barely hand tight.

Once these steps are complete, you are ready to reinstall your wheel.
