Gotrax Scooter Back Wheel Locked Up? 3 Easy Solutions!

The rear wheel getting locked up can be very dangerous, especially, if you were riding it. The problem is common and may happen at any time.

So, why is your Gotrax scooter back wheel locked up?

Setting the brake too tight is the most common reason for the back wheel to get locked up. You need to adjust the brake accordingly if that’s the case. A damaged disc brake or wheel bearings may also be the cause. Such a situation requires a proper diagnosis and a replacement if necessary.

In the next parts, we will explore all the reasons and the solutions to this problem.  

Why Is Your Gotrax Scooter Back Wheel Locked Up?

Back wheel getting locked up is a common issue and the solutions are also very straightforward. Before we get on with the problem-solving, here are a couple of troubleshooting methods for your Gotrax scooter to help pinpoint the problem.

So, without wasting any more time, let’s get to the troubleshooting process-

Reason Solution
Brake too tight Adjust the brake
Bent disc brake Repair or replace the disc brake
Worn out bearing Replace the bearing

Reason One: Brake Too Tight 

One of the most common reasons for the back wheel to lock up is having the brake too tight. Too much brake pressure can cause the brake pads to clamp down too tightly on the wheel, making it difficult or even impossible to move. 

Solution:

To adjust the brake on a Gotrax scooter, follow these steps:

  • Start by checking if the brake needs a small or large adjustment. 
  • If the brake needs a small adjustment, adjust it using the adjuster. Some have a plastic knob, while others have a lock nut. Use an open-end wrench to unlock the lock nut, then adjust the brake tension as needed.
  • While adjusting the brake tension, push the cable up and turn the wrench to tighten the brake. Turn it counterclockwise to loosen it. Turn it about 1/6 of a turn each time, checking for brake drag.
  • If it needs a large adjustment, go straight to the cable clamp.
  • Take an Allen wrench and loosen the cable clamp. Hold onto the cable and slide it forward as far as possible. Lock it down again.
  • Once you’ve adjusted the brake cable, check that the brake light still works. You want to make sure that the brake light comes on at the same time the brakes engage, as this triggers the regenerative brake.
  • If the brakes still don’t feel right after adjusting the cable, you can do a caliper adjustment. To do this, loosen the two bolts that hold the caliper in place, then spin the wheel and grab the brakes. This will center the caliper on the rotor. While holding the brakes, snug the caliper down a little at the front and a little at the back until it’s in the right position.
  • If the caliper adjustment doesn’t work, you can do a full caliper adjustment. To do this, start by releasing the brake cable using the cable clamp. This will give you plenty of room to work with the outer brake pad.
  • Use a 2mm Allen wrench to unlock the inner brake pad and adjust it out of the way. Then, adjust the caliper forward and back using the slots in the caliper until it’s centered on the rotor. Lock it back down.
  • Bring the rear pad back in, going all the way back in one turn plus half a turn. You should start to feel some real drag at this point. Back it off a quarter turn until it’s free.
  • Test the brake to make sure it’s working correctly.

Reason Two: Bent Disc Brake 

A bent disc brake on a Gotrax scooter is very common, especially after an accident. As an aftermath of the accident, owners experienced a locked rear wheel. Even if the situation seems severe, it may not be the case and the solution is often a simple one.

Solution:

You can follow these steps to diagnose a bent disc brake on your Gotrax scooter:

  • Check the severity of the bend: If the brake disc is bent at a 45-degree angle or more, it is beyond repair and needs to be replaced.
  • Check if the brake disc can make it to the caliper: If the brake disc is bent but can still make it to the caliper, then you can try to tweak it back into place.
  • Adjust the brake caliper: Try adjusting the brake caliper first to see if it fixes the issue. If not, move on to the next step.
  • Check wheel alignment: If adjusting the brake caliper doesn’t work, check the wheel alignment. If it’s off, that can cause the brake disc to rub against the caliper. Adjust the alignment and test again.
  • Identify the area of the brake disc that is affected: Use the brake caliper as a reference point and spin the wheel to see where the disc is touching the caliper.
  • Use a tool to straighten the brake disc: Use a special disk rotor tool or an adjustable spanner to bend the affected area of the brake disc back into shape.
  • Continuously tweak and adjust the brake disc: It may take some trial and error to get the brake disc back into shape. Keep adjusting until the disc no longer rubs against the caliper.

Here is a video for the whole diagnosis process for your convenience-

Note: Your brake disc will never be as good as a new one, but as long as it passes through the calipers without rubbing, you can go back to riding your electric scooter.

Reason Three: Worn-Out Bearing

Another reason the rear wheel is locked up is worn-out bearings. If you suspect that’s the case you will have to open up your scooter and take a look. 

Solution:

Here’s how to check the wheel bearings on your Gotrax electric scooter:

  • First, remove the wheel from the scooter.
  • Check for any visible damage or wear on the wheel and axle.
  • Remove the dust cap that covers the center of the wheel using a screwdriver.
  • Inspect the bearing for any damage or wear. If the bearing is damaged or worn, it needs to be replaced.
  • Use a bearing puller or a hammer and punch to remove the old bearing from the wheel.
  • Clean the inside of the wheel hub and axle with a cloth or brush.
  • Press the new bearing into place using a bearing press or a socket of the appropriate size.
  • Replace any spacers or washers in their proper position.
  • Tighten the axle nut to the appropriate torque specification.
  • Replace the dust cap.
  • Use some silicone lubricant to wipe off any excess.
  • Reinstall the wheel on the scooter’s frame and tighten the bolts that hold the wheel in place.
  • Repeat the process for the other wheel if necessary.
  • If you have trouble removing the bearing, try giving it some WD40 or other lubricant to help loosen it. You can use a washer and a tubular head from a kit to help remove the bearing. Place the washer on the bearing, then place the tubular head in the middle and use two hammers to tap it out.

Note: It’s important to note that the bearing size may vary depending on the model of the scooter. Check the bearing for any markings or numbers to determine the correct size.

How to Properly Maintain Your Gotrax Scooter?

Keeping your electric scooter clean and well-maintained is essential to prolonging its lifespan and ensuring optimal performance. Here are some tips to help you take good care of your scooter:

  • Keep your scooter’s tires properly inflated to the recommended PSI, which is 50. This will help ensure a smooth and safe ride. Also, make sure to follow the correct process of repairing a flat tire on your scooter. 
  • Clean your scooter regularly with a soft damp cloth to keep it looking and functioning at its best.
  • Avoid using alcohol, gasoline, kerosene, or other corrosive chemical solvents to clean your scooter, as these can damage the appearance and structure of your scooter.
  • Do not use a pressure washer to clean your scooter, as this can cause damage to the electronics.
  • If you need brake adjustments or any service on your scooter, contact the customer service team for assistance. Do not attempt to repair your scooter yourself, unless you know what you’re doing. This can void your warranty and may cause further damage.
  • Avoid exposing your scooter to the sun when not in use to prevent damage to its appearance and battery life. Ensure proper storage solution for your scooter.
  • If you notice that the tiller is loose or wiggles while riding, you can tighten the screws. Simply open the plastic cover and use the Allen wrench to tighten the screws.

By following these simple maintenance tips, you can keep your electric scooter in top condition and enjoy a safe and enjoyable ride every time.
