How to Install the Rear Hub Motor on Your Arwibon GT06PLUS

Following the disassembly of the rear drive assembly, correctly reinstalling the hub motor on your arwibon GT06 PLUS is essential for ensuring peak performance, smooth braking, and structural safety. High-performance models in the arwibon scooter family, including the arwibon GT06 series, rely on heavy-duty swingarm dropouts, dedicated axle-locking hardware, and precise wire-routing channels to handle dual-motor torque.

Improper installation can lead to damaged phase wires, brake rotor drag, or axle slippage under hard acceleration. This guide walks you through the entire reassembly workflow for your arwibon electric scooter—from seating the axle into the swingarm dropouts to connecting the primary controller harness in the deck.

Required Tools and Equipment

Prepare the following tools before beginning the installation process:

• Sturdy Lift or Elevated Workstand: Keeps the chassis elevated and the rear dropouts fully accessible.

• Air Impact Wrench or Long Socket Wrench: Fitted with a heavy-duty 19mm/21mm socket for torquing down main axle locknuts.

• T-Handle Hex / Allen Keys (4mm & 5mm): Used for swingarm pinch screws, brake caliper bolts, and decorative covers.

• Needle-Nose Pliers: Used to guide, tension, and secure the motor axle retaining wire.

• Zip Ties (Cable Ties) & Snips: To bundle motor phase cables securely along the swingarm channel.

• Clean Rag: For wiping down axle mating surfaces and brake rotor surfaces.

Step-by-Step Installation Walkthrough

Step 1: Slide the Motor Axle into the Swingarm Dropouts

1. Stand directly behind the chassis of your arwibon e scooter. Hold the 11-inch tubeless tire squarely with both hands.

2. Align the milled flat edges of the motor axle with the open horizontal slots in the left and right swingarm dropouts.

3. Push the entire wheel assembly forward into the dropouts until both axle ends bottom out fully and evenly against the stops.

4. Verify that the brake rotor slides smoothly between the open gap of the swingarm frame without striking the metal edges.

Step 2: Install Axle Washers and Fasten the Main Locknuts

1. On the left and right axle ends, slide on the anti-rotation tabbed washers, ensuring the tabs seat firmly into the swingarm alignment cutouts.

2. Thread the large hexagonal axle locknuts onto the threads by hand to prevent cross-threading.

3. Fit your air impact wrench (or a long breaker bar with the appropriate socket) over each axle nut.

4. Torque down the left and right nuts firmly and evenly to lock the motor securely to the swingarm frame.

Step 3: Install and Align the Rear Disc Brake Caliper

1. Retrieve the mechanical disc brake caliper that was set aside during teardown.

2. Slide the caliper body over the outer edge of the brake disc rotor, aligning its mounting brackets with the swingarm bosses.

3. Thread in the upper and lower 5mm hex mounting bolts loosely so the caliper retains slight lateral movement.

4. Spin the rear wheel vigorously by hand while inspecting the gap between the rotor and the brake pads.

5. Squeeze and hold the corresponding brake lever (or align the caliper by sight so the rotor sits centered in the pad slot with zero scraping sound), then tighten down both 5mm mounting screws alternately until fully torqued.

6. Spin the wheel again to confirm that the tire rotates smoothly and quietly without brake drag.

Step 4: Route and Zip-Tie the Motor Cable Along the Swingarm

1. Guide the thick black motor harness forward along the inner profile of the swingarm arm.

2. Pass zip ties through the pre-drilled cable guide holes on the swingarm.

3. Cinch the zip ties securely around the cable and snip off the excess plastic tails, keeping the harness tucked neatly away from the spinning tire tread and brake rotor.

4. Direct the end of the cable toward the rear entry port of the main deck frame.

Step 5: Mount the Swingarm Fork Covers and Emblems

1. Take the left red swingarm fork cover and slide it over the outer side of the swingarm assembly.

2. Align the counter-sunk mounting holes with the threaded bosses in the frame.

3. Using your T-handle hex key, thread in and tighten the two internal counter-sunk screws firmly.

4. Repeat the procedure on the right swingarm cover, securing its two counter-sunk mounting screws evenly.

5. Retrieve the black oval GT06 emblem badges, peel away the protective backing if re-applying adhesive, align them with the recessed channels on each cover, and press down firmly across the surface to seal.

Step 6: Route Wiring into the Battery Deck and Reconnect

1. Push the heavy-duty yellow motor connector and the small white Hall-sensor plug forward through the rubber grommet port into the rear electronics bay.

2. Pull the cable slack through so the outer jacket sits comfortably through the frame grommet without tension.

3. Connect the primary power connector: align the heavy-duty yellow 3-pin motor connector with its matching yellow socket on the controller board and push it in firmly until fully seated.

4. Connect the multi-pin Hall-sensor plug: align the pins with the controller's matching female connector and snap the locking tab shut.

5. Organize the wiring harnesses inside the deck cleanly, away from any sharp edges, before reinstalling the top deck plate.

Pro Reassembly Tips for Your Arwibon

• Axle Alignment Inspection: Before running the impact wrench on the axle locknuts, double-check that both axle ends sit at the exact same depth in the dropouts. An off-center axle tilts the tire toward one side of the swingarm, causing uneven tire wear and disc rub.

• Waterproof Grommet Fitment: When feeding the motor harness into the deck cavity, ensure the rubber cable pass-through grommet is pressed cleanly into the aluminum entry hole. This maintains splash resistance against water kicked up by the rear tire.

• Electrical Connection Check: Always ensure the main battery switch or master circuit is off before mating the yellow high-current connector to avoid arcing. Confirm that the latch on the Hall-sensor plug clicks audibly into place to prevent intermittent throttle error codes during rides on your arwibon scooters.
