Top-performing electric scooters are becoming more and more popular over time. They are an excellent means of transport. They are also easy and cheap to maintain since they don’t have a lot of serviceable parts. But like any other vehicle, it may encounter problems and fail to start.

KEY TAKEAWAYS:

  • Your electric scooter throttle is the device that controls the flow of power from the battery to the motor.
  • If your e-scooter is not moving even when on, then there’s a high chance your throttle is damaged.
  • If your electric scooter throttle failed within the guarantee period, then it would be a wise decision to get in touch with your manufacturer as soon as possible.

When your electric scooter fails to start due to lack of power, it’s often due to many reasons. For example, if your battery is fully charged and it’s still not working, your throttle could be faulty. If charging is the problem, learn how to fix a battery that’s not charging. Fortunately, learning how to fix a scooter throttle is not rocket science. Fortunately, we have outlined a complete step-by-step guide on how to fix this problem.

What is a Throttle?

Your electric scooter throttle is the device that controls the flow of power from the battery to the motor. There are several types of electric scooter throttles. The most commonly used is the half-effect throttle or accelerator, or twist bar. The other kinds of throttles include:

  • On and off the throttle
  • High-end throttle
  • Thumb foot throttle
  • Half twist

Troubleshooting the Throttle

If your e-scooter is not moving even when on, then there’s a high chance your throttle is damaged. To confirm for sure the throttle is damaged, do the following:

  • Take off the lead on the top deck to view to wire connections. First, check that they are firm. If not, tighten them.
  • If you notice any melted wires, it might mean that your electric scooter throttle has overheated, and it will need a replacement.

Testing an Electric Scooter Throttle

An electric scooter throttle is easily identifiable, and it usually comes with three colored wires; black, red, and green or blue.

If the speed display lights fail to come on when you twist the e-scooter throttle, your throttle might be faulty. Alternatively, the problem might be due to a connection issue between the controller and the throttle.

To successfully test the throttle, do the following:

  1. Turn off your e-scooter and detach the fuse. Lift up the rear wheels of the e-scooter ensuring that you are not in the vicinity of the back wheels.
  2. Connect a DC 4.3 volts positive multimeter to the throttle’s red wire. The black wire needs to be connected to the DC 4.3 volts ground.
  3. Attach the voltmeter to the black and green wire or the blue wire. Replace the fuse, and turn on the e-scooter. Turn or twist the motor to activate the motor. The motor should be running.

If you notice that the motor is not running, the problem could be with the battery, connection with the controller, or the ignition key. If the motor turns, then your throttle is faulty.

Ideally, the voltmeter needs to read between 0 to +3 volts. Unfortunately, in case the number is low, your e-scooter throttle is faulty.

Fixing an Electric Scooter Throttle

If you discovered from the throttle test that your battery is faulty, you need to replace it. However, if the problem is due to a connection between the throttle and the controller, it is wise to have an expert diagnose and solve the problem.

The worst possible thing you might need to do is replace the electric scooter throttle altogether. If this happens, you need to be prepared for the outcome.

Better yet, if your electric scooter failed within the guarantee period, then it would be a wise decision to get in touch with your manufacturer as soon as possible. Depending on the manufacturer of your e-scooter, the warranty might fully cover the replacement and repair of the throttle or at a subsidized cost. It may also be a great idea to know how to get insurance for your e-scooter.

F.A.Q.

What is a throttle?

Your electric scooter throttle is the device that controls the flow of power from the battery to the motor.


What does a throttle do in an electric scooter?

The throttle on your scooter is quite similar to the one on a motorcycle in operation. When engaged, it signals the motor to produce power to move the scooter forward. Throttles can be fine-tuned like a volume button to increase or reduce speed.


How will I know my throttle is faulty?

If your e-scooter is not moving even when on, then there’s a high chance your throttle is damaged.


Will my electric scooter be able to move with a faulty throttle?

Unfortunately, your electric scooter can’t move when your throttle is damaged. The electric scooter throttle is what signals the motor to provide power to move the scooter. Without its functionality, the scooter won’t be able to move.


STAT: The global sale of e-scooters in 2019 was approximately 46.89 billion. It was projected to get to 50 million units by the end of 2020. By 2029, this figure is expected to rise to 129 million (source)
