How to Install the Rear Wheel Motor on an Arwibon GT08 Scooter

The rear motor wheel on the arwibon gt08 scooter sits directly in the rear swingarm and connects to the controller through three phase wires and a Hall sensor harness. After the motor wheel is positioned in the swingarm, the axle hardware, brake caliper, motor cable, controller wiring, and rocker arm cover all need to be put back in place.

Although the official video is titled “GT08 Rear Wheel Motor Removal,” the procedure shown in the material you provided mainly covers rear motor installation and reassembly. The steps below follow that process.

Step 1: Position the Rear Motor Wheel in the Swingarm

Lift the rear motor wheel and align both sides of the motor axle with the open slots in the rear swingarm.

Lower the axle into the slots evenly.

The official arwibon gt08 video shows the motor wheel going into position at about 00:12.

Check both sides before installing the axle hardware. The axle should sit correctly in the swingarm instead of resting partially above the slot.

Step 2: Install the Anti-Rotation Hardware and Axle Nuts

Fit the anti-rotation washers or locating hardware back onto the motor axle in the same position used before removal.

Install the main axle nuts on both sides.

Use an open-end wrench, box wrench, or suitable socket to tighten the axle hardware.

This part begins at about 00:19 in the official GT08 tutorial.

Work on both sides rather than finishing one side while the other remains loose.

The rear motor carries drive torque through the axle, so the locating hardware needs to sit correctly against the swingarm before the nuts are tightened.

Step 3: Reinstall the Rear Brake Caliper

Position the rear brake caliper over the brake disc.

Align the caliper with the mounting holes on the rear swingarm.

The official arwibon gt08 electric scooter video shows the caliper being positioned at about 00:41.

Insert the mounting bolts but leave them slightly loose at first.

This gives you enough movement to adjust the caliper around the brake disc.

Step 4: Adjust the Caliper Position

Look through the caliper and check the position of the brake disc between the pads.

Move the caliper slightly if necessary so the disc does not sit hard against one side.

Once the position looks correct, tighten the caliper mounting bolts with the Allen wrench.

The adjustment and tightening are shown at about 00:51.

Afterward, rotate the rear wheel by hand.

The official gt08 scooter video checks wheel movement at about 01:08.

The wheel should rotate without obvious binding or abnormal contact around the brake disc.

Step 5: Route the Rear Motor Cable Along the Swingarm

Take the motor cable coming from the axle and route it along the inside of the rear swingarm.

Follow the original cable path.

Use zip ties to secure the cable to the rocker arm.

This begins at about 01:17 in the official arwibon scooter gt08 tutorial.

Do not pull the motor cable tight between the axle and the frame.

Leave enough movement for the rear suspension to travel without stretching the cable.

At the same time, avoid leaving a large loose loop where the cable can rub against the tire, brake disc, or other moving parts.

Step 6: Feed the Motor Harness Into the Deck

Guide the motor harness toward the rear cable opening in the deck.

Feed the wires through the opening and into the battery and controller compartment.

The video shows the cable entering the deck at about 01:21.

Push the harness through gradually.

Watch the connector ends as they pass through the frame opening. Do not pull hard enough to damage the insulation or terminals.

Step 7: Connect the Three Motor Phase Wires

Locate the three thick motor phase wires.

The official GT08 installation shows yellow, green, and blue phase wires connecting to the corresponding controller terminals.

Match the colors as shown in the original wiring:

• Yellow to yellow
• Green to green
• Blue to blue

The phase-wire connection begins at about 02:04.

Place each terminal correctly under its controller connection and tighten the terminal screw with a screwdriver.

Check each wire after tightening.

A loose phase-wire connection is not something to leave for later. These wires carry motor current, so each terminal needs to remain firmly connected.

Step 8: Assemble the Hall Sensor Connector

The motor also uses a smaller Hall sensor harness.

In the official video, the Hall wires are shown in red, black, yellow, green, and blue.

If the terminals are separate from the white connector housing, insert them into the connector in the original positions shown for the GT08 harness.

This process appears at about 02:26.

Push each metal terminal fully into the plastic housing.

After inserting a terminal, lightly pull the wire back to check that it has locked into place.

Do not change the pin order based only on wire color if your connector has already been altered or differs from the original layout. Use the original GT08 wiring arrangement as the reference.

Once the connector is assembled, plug the motor Hall connector into the matching controller connector.

Step 9: Check the Motor Wiring Before Closing the Scooter

Before reinstalling the rocker arm cover, check the motor cable from the wheel to the deck.

Make sure:

• the phase-wire terminals are secure;
• the Hall connector is fully seated;
• no wire has been pinched at the deck opening;
• the cable is secured to the swingarm;
• there is enough movement for the rear suspension;
• the cable cannot rub against the rear tire or brake disc.

If the cable routing looks wrong, correct it now while everything is still accessible.

Step 10: Reinstall the Rocker Arm Side Cover

Place the red or orange protective cover back over the outside of the rear rocker arm.

The official arwibon gt08 tutorial shows the cover being installed at about 02:59.

Line up the cover with the mounting points.

Insert the two hidden Allen screws and tighten them.

The screws are installed at about 03:04.

Make sure the cover sits flat against the rocker arm before tightening the screws fully.

Step 11: Reinstall the GT08 Logo Plate

Once the side cover is secure, place the black GT08 logo plate back over the recessed area.

Press it evenly into position.

The official video shows this final step at about 03:13.

The logo plate covers the two side-cover screws, so confirm the hardware underneath is already secure before fitting the plate.

Step 12: Final Check

Before riding the arwibon gt08 scooter, inspect the rear wheel assembly again.

Check that:

• both axle nuts are installed and secure;
• the anti-rotation hardware is correctly positioned;
• the rear brake caliper is firmly mounted;
• the wheel rotates without obvious brake drag;
• the motor cable is tied securely along the swingarm;
• the phase wires are connected to the correct controller terminals;
• the Hall connector is fully assembled and plugged in;
• the motor cable is not pinched or stretched;
• the rocker arm cover and GT08 plate are back in place.

If the motor wiring was disconnected during the repair, complete the electrical connections before reconnecting the main battery power.

This procedure follows the official Arwibon Scooter GT08 rear motor tutorial and covers installation, wiring, and final reassembly of the rear motor wheel on the arwibon gt08 electric scooter.
