Razor scooters are among the best there is, especially if you consider their prices. There are different models to choose from, both for adults and kids. RazorUSA, the company making these scooters, introduced its first electric scooter back in 2003 and has continued to release newer models with improved features and capabilities ever since. Being electric, these units can develop issues, perhaps more often than a traditional Razor scooter would. If you are having problems with your Razor electric scooter, troubleshooting the unit can often help resolve the issue. This is a simplified how-to and troubleshooting guide to help you with some of the challenges you might be having with your Razor scooter.

Razor Scooter Charging Problems and Their Fixes

Scooter does not run

  1. The battery could be undercharged. Make sure you charge the battery. A new battery should be charged for at least 18 hours before using the scooter for the first time and up to 12 hours after each subsequent use.
  2. Check for loose wires or connectors. Make sure the charger connector is tightly plugged into the charging port and that the charger is plugged into the wall.
  3. Confirm if charger is working properly. Check the lights on the charger. Green for standby, red when charging and green again when charging is complete. Replace the charger if there are no lights/blinking lights.

Short run time (less than 15 minutes per charge)

  • The battery could be undercharged. Make sure you charge the battery properly. A new battery should be charged for at least 18 hours before using the scooter for the first time and up to 12 hours after each subsequent use.
  • Check all wires and connectors. Make sure the battery connector is tightly plugged into the charger connector, and that the charger is plugged into the wall.
  • The battery could be old and won’t accept a full charge. Make sure the power flow to the wall outlet is on.
  • With no weight on the unit, lift up the back end, then manually spin the rear wheel and apply throttle to engage the motor.  If the motor engages, you need to replace the battery.
  • Even with proper care, a rechargeable battery does not last forever. The average battery life is 1-2 years depending on scooter use and conditions. Make sure you replace only with a Razor replacement battery.

Razor Scooter Clicks But Won’t Go

If your Razor E200/E300 scooter clicks but the rear wheel barely moves, try the following:

  • Lift up the rear end and manually spin the rear wheel forward. It should spin 3-4 times with no resistance.
  • If the wheel does not spin freely, replace rear wheel.

If the battery shows fully charged, power switch light up, but scooter does not move, try the following:

  • Check for loose connection(s) underneath the deck plate. If connections are loose reconnect them.
  • Secure the unit; turn the power on and with no weight on the unit, lift up the back end and apply throttle. If the rear wheel spins freely, replace the battery and/or charger.
  • Remove the deck plate and unplug the brake connector from Control Module. Secure unit; turn the power on and apply throttle. If the motor engages/rear wheel spins, then replace the brake lever.
  • If the motor does not engage, replace the throttle and control module.

Razor Scooter Does Not Work

If your Razor E100 electric scooter does not work out of the box, the motor may not have engaged. The unit must be traveling at least 3 mph (5 km/h) before the motor will engage. Kick to start to at least 3 mph (5 km/h) while pressing down on the thumb throttle to engage the motor.

If the scooter still does not work, check for loose connections/wires underneath the deck plate and make sure the connections are properly and tightly secured.

If your Razor E100 scooter used to work but no longer works, check the following:

  1. Loose connections- Check for loose connections/wires underneath the deck plate.
  2. Charger is not working- Check the lights on the charger:
  3. Plugged into wall-Green
  4. Plugged into wall and unit- Red (charging)
  5. Plugged into wall and unit- Green (charging complete)
  6. No lights/blinking lights- Replace the charger
  • Battery will not hold charge- With no weight on the unit, lift up the back end, then manually spin the rear wheel and press down on the thumb throttle to engage the motor.
  • If the motor engages, replace the battery.
  • If the motor does not engage but makes a clicking sound, replace the battery.
  • If the motor does not engage and there is no clicking sound, replace the control module.
  • Tripped reset button- The reset button will trip if the motor is overloaded. An excessive overload can be caused by a hill that is too steep, a rider that is too heavy, etc. If the reset button trips, wait for a few seconds then press the reset button. Correct the riding condition to prevent overload.

Razor Scooter Reset Button Location

The reset button in a Razor scooter is located next to on/off switch. The reset button/circuit breaker will automatically shut off power if the motor is overloaded.

An excessive overload, such as too heavy a rider or too steep a hill, could cause the motor to overheat. If your scooter suddenly stopped working while in use, it is likely the reset button/circuit breaker tripped.  If that is the case, wait a few seconds and then push the breaker to reset the circuit. Correct the condition that caused the breaker to trip and avoid repeatedly tripping the breaker.

Razor scooter charger light stays green

The solid green indicates the unit is fully charged. The charger light also lights green when the charger is unplugged from the scooter but is still plugged into the wall AC outlet. The light turns red when the charger is plugged into the wall and into the scooter’s charging port and is charging.

If the charger light stays green and there is no red light when the charger is plugged into the wall and into the scooter charging port, it could be from new batteries that have never been used and have a full charge. If that is not the case, the batteries could be worn out with low voltage and need to be replaced, there could be a loose wire or defective connector between the battery pack and charger port, the charger, charger port or battery charger plug could be defective, or there could be a burned out fuse in the charger.

Razor electric scooter making clicking noise

When the controller clicks and the scooter does not move that is typically cause by an old or worn-out battery pack.

The voltage level of an old or worn-out battery pack will drop significantly when the throttle is engaged, which will give the controller enough power for its internal relay to click, but not sufficient power to operate the motor. Try and see if those batteries are dead and replace them with good ones.

Besides an old or worn-out battery, another possible cause is a defective brake lever switch. Try disconnecting the brake lever switch from the controller and see if the scooter works then.

Should Razor Scooter Be ON When Charging?

No, you need to make sure power is turned OFF when the scooter is not in use. If the power switch is left on for an extended period of time, the battery may reach a stage at which it will no longer hold a charge.

When charging your Razor scooter, follow these instructions:

  1. Plug the charger plug into a wall outlet. The light on the charger should be green. If the green LED light does not turn on, try a different outlet.
  2. Plug the charger into the charger port on the unit. Make sure the power switch is in the OFF position. The light on the charger should turn red during charging. The light will turn green again when charging is complete.
  3. Initial charge time for the Razor E100 scooter is 12 hours. Recommended recharge time is up to 12 hours, even if the light turns green. Recommended maximum charging time is 24 hours.
