The G-FORCE S10 comes with a hub (in-wheel) motor to power the scooter forward. That is to say, the electric motor is incorporated directly into the hub of the rear wheel - the motor and wheel are one, so what is referred to in this guide is to replace the rear wheel assembly.

Remove the Hub Motor

Step 1: Turn off the scooter and put it in a repair stand for easier access to work on.

Step 2: Unscrew 3 screws holding the rear fender (splash guard) onto the scooter deck, and then remove the rear fender.

Step 3: Unplug the rubber end cap on the left axle nut.

Step 4: Use a screwdriver to remove 2 screws from each side of the deck. Then grip and pull off the taillight plates from the both sides.

Step 5: Loosen the axle nuts on each side of the rear wheel by using a 18mm Allen wrench.

Step 6: Whack the tire tread by palm to slide the wheel out of the rear dropouts - two slots on the frame.

Step 7: Stand at the front of scooter, and remove 3 screws on the base plate by using a screwdriver. Then grip and pull off the front plastic panel from the frame.

Step 8: Locate the motor controller - a small silver block, and then disconnect the the following connectors from the motor controller: 3 green-covered one-pin wire connectors and a 5-pin wire connector (attached 5 cables: red+yellow+green+blue+black).

Step 9: Pull the black motor cable out through the frame.

Install the New Hub Motor

Step 1: Locate the tire valve and let partial air out of the tire by pressing in the center of the valve stem (a thin pin). Basically, the top of the screwdriver can do the job.

Step 2: To get the tire off the wheel, lift the tire wall off the rim by using tire levers.

Step 3: Mount the tire on the new wheel rim and have the tire inflated to a proper PSI.

Step 4: Reinstall the rear wheel. Place the entire wheel in the frame dropouts - the slots in the frame where the rear axle sits. Then tighten the axle nuts on both sides.

Step 5: Thread the motor wires through the deck enclosure. Then plug in the motor connectors in accordance to the color scheme, and put back the rubber axle nut cap.

Step 6: Put back the taillight plates and front plastic panel. Make sure all screws are tightened.
