How to repair an Electric Scooter – it’s so easy

Electric scooters are both environmentally friendly and a lot of fun to ride. It’s a sad truth of life that eventually something on your electric scooter will need to be mended. Fortunately, fixing electric scooters is not that difficult. The following nine factors should be looked at if your electric scooter stops operating.

9 issues to look for while fixing electric scooters

  • Reset your scooter

A reset button or process is included on a lot of electric scooters. Consult the instructions if you’re unsure how to reset your scooter. If you don’t already have one, look for your electric scooter’s handbook or guide online.

  • Check for a kill or arming switch in step two.

An arming switch or kill switch is common in electric scooters. The scooter can now be powered on, but the motor won’t operate until the switch is in the right position. If your scooter’s display is on and it still won’t move, check this. If you are unsure of its location on your electric scooter, consult the handbook or search online for one.

  • Inspect the circuit breaker or fuse

Fuse or circuit breakers are typically seen in electric scooters. This guards against harm to the electronics, batteries, and motor. Overcurrent damage may result from using your bike at full power while the motor is stalled. This is avoided by the fuse or circuit breaker. You could have blown the fuse if your scooter got stuck or halted. Your scooter may have shorted a circuit and blown a fuse if it was wet or rained on it. Check the handbook to see whether your scooter has any fuses or circuit breakers.

Hold a fuse up to a light to inspect for any burned connections within. A multimeter may be used to test the fuse for conductivity as well. A burned fuse results in an open circuit.

  • Verify that the battery is completely charged.

Make sure the battery in your electric scooter is completely charged. You can’t use your scooter if the battery is dead. There could be enough battery remaining to turn on the display and electronics, but not enough to operate the scooter.

You should fully charge the battery before attempting to ride your scooter if it has been a while since your last ride.

To make sure the charger is operating properly, check the lights on both the battery and the charger. Different chargers employ various lighting schemes. To find out what your scooter’s battery charger should indicate, see the instructions.

  • Examine the motor.

Examine the motor. On electric scooters, there are several different motor positions and types. Some front or rear wheels have hub motors integrated into them. Some rear wheels are driven by belt or chain. On some powerful scooters, both the front and back wheels are driven by motors.

Inspect the engine for any debris that may have become lodged there and caused it to stall.

Make sure the connections at the motor are firmly connected in by checking them. Examine the wire for signs of wear or rubbing that might result in a short circuit.

the motor’s scent. It shouldn’t have a burning scent. Burning smell is a sign that the wiring has burned out and the motor has overheated.

The absence of brushes indicates that the motor is brushless. Three power lines exit the motor in brushless motors.

  •  Verify the wiring

Examine the wiring in and around your scooter. Verify that all connectors are plugged in by checking them all. Make that the connection leads are still connected by checking the leads coming out of them. To avoid breaking a connection while inspecting it, don’t tug too firmly on any lead.

Check the wire for signs of chafe or damage. This is most frequently seen when wires are wrapped around sharp edges or when they are subjected to heavy wear.

There can be a loose link somewhere in the system if your electric scooter only operates occasionally. Sometimes it’s OK, other times it’s not. A loose connection may be causing a circuit to open, close, and then reopen.

  • The speed controller should be examined.

The battery, motor, throttle, and brakes will all be connected to the speed controller. Any display on your scooter will be able to link to it as well. This is actually your electric scooter’s brain. Your speed controller’s connections should all be checked. Check it out for any burning smells. The speed controller won’t function if any switches or transistors are burned out. It must be replaced if this is the case. For information on where to get replacement components for a new controller, consult the handbook for your electric scooter.

  •  Examine the brake lever switch.

Your electric scooter has a switch on the brake lever that, when depressed, disables the motor. Normally, the brake lever has an open/close switch. Your motor won’t operate if this switch is broken or trapped in the “brakes on” position. You may use a multimeter to inspect this switch. When the brakes are engaged, the circuit should be open or closed. When the brakes are let off, it should be the other way around.

  • Inspect the batteries.

One of the most intricate and critical components of your scooter is the battery. If your electric scooter is not moving at the speed and distance it formerly did, the battery may be the problem.

There will be a lot of cells in the battery. That can be connected in both parallel and series fashion. You could also have balancing circuits if your batteries are lithium polymer or lithium ion.

The battery is the main problem if the speed of your electric scooter has decreased. An electric motor’s ability to spin at a specific RPM at a specific input voltage is known as its k-value. The motor spins more slowly as the voltage decreases.


It might be time to take it to a repair shop if you’ve gone through the list and still can’t identify the issue. Electric scooter repairs can be simple, but some issues may require more expertise. Your scooter’s handbook should be checked first to determine if there is a location to submit it for repairs. Send your scooter back if it’s brand new and broken. Avoid digging too deeply into your scooter if you want to return it for a refund if it’s new.

There is no customer care or support for many scooters in the US because they were made in China. It’s time to turn elsewhere for assistance in this situation.

While some bike shops will service electric scooters, many won’t. You might also try a general electronic repair shop. One more place to look is a hobby store. An electric scooter has many of the same electronics as an RC vehicle or plane.
