Replace Display

First, loosen the nut at the brake cable of the drum brake with a 14 mm wrench.

Then, loosen the rear brake with a 5 mm Allen key.

Carefully remove the brake cables from the brake levers so that the steering head can be disassembled freely later on.

Loosen the four steering head screws with a 3 mm Allen key. There are two screws in the front and two at the back.

Then carefully pull out the entire steering head and disconnect the display cable from the wiring harness.

Use a 2.5 mm Allen key to loosen the screw of the front light. The screw is located on the left side of the light cover in the direction of travel.

Then carefully remove the shrink tubing with a carpet knife and unplug the light cable.

Loosen the two screws in the light cover with a 3 mm Allen key and carefully remove the light cover.

Carefully remove all shrink tubes and then disconnect all connectors.

A total of six connectors will be disconnected in this step. Work carefully to avoid damaging any pins.

Use a 5 mm Allen key to loosen the four screws that connect the handlebar and the head.

Be especially careful not to damage any cables. Then carefully separate the handlebar from the head.

Loosen the four cross screws on the display and remove them completely.

Then carefully pull the display out of the mount.

Carefully insert the new display into the mount. The cable that leads to the wiring harness in the front stem is black with a green connector.

The other cables are fed out where the light will later sit. Then retighten the four cross screws by hand.

Put the handlebar back on the head, making sure no cables are caught in between.

Align everything neatly so that the four 5 mm Allen screws can be reinserted correctly, and then tighten them by hand.

Now plug in all connectors again. Work carefully to avoid damaging any pins.

If available, reseal the connections with shrink tubes.

Carefully push all cables back into the head. The light cable remains outside for now.

Make sure no cables are kinked or pinched.

Position the light cover correctly and guide the light cable in neatly.

Then tighten both 3 mm Allen screws and secure the light cover.

Plug the light back in. If available, slide a shrink tube over the connection again.

Carefully insert the light beam into the light cover without damaging the cables, and secure the light with the 2.5 mm Allen screw.

Reattach Steering Head

Plug the wiring harness back in and carefully place the steering head back onto the steering tube.

Again, be careful not to damage or pinch any cables. Then secure the four steering head screws with the 3 mm Allen key.

Reinsert Brake Cables and Adjust Brakes

Thread the brake cables back through the brake levers crosswise.

Finally, adjust both brakes neatly and check their function carefully.

When reassembling, ensure that all screws are properly seated and no cables are pinched or damaged.

Check Results

After reassembly, check whether the new display is properly seated and all connectors are securely connected. Also, check if the front light works and both brakes are correctly adjusted.

Turn on your VMAX e-scooter after the repair and test the display, light, and brakes first while stationary. Only then take a short, cautious test ride.

Frequently Asked Questions

Here you will find answers to common questions about this repair.

What should I do if a connector is hard to disconnect?

Never pull connectors apart with force. Check first if a shrink tube or a clip is still blocking the connection. Work slowly and straightforwardly to avoid damaging any pins.

The new display does not work after installation. What should I check?

Check all connectors again first. The connection from the display to the wiring harness is particularly important. Also, check if any cables were pinched during reassembly.

Do I need to check the brakes again after replacing the display?

Yes, definitely. Since the brake cables are loosened for this repair, you should adjust both brakes carefully at the end and thoroughly check their function before riding.
