Keeping your E-Twow scooter in top shape means quickly identifying what’s wrong when something doesn’t feel right. Many common issues can be narrowed down at home before you order spare parts. Here’s a simple guide to help you understand the most frequent errors, symptoms, and what parts you may need to replace.
1. Check for Error Codes on the Display
E-Twow scooters display error codes when something isn’t working properly. These codes are the first clue.
Error E1 shown on the display
If your scooter shows this error, it probably is a communication problem between controller and motor. First step is to check the motor cable (if it's well plugged-in and if it has any marks that's damaged) and then the controller (if possible with a multi-meter).
Error E2 shown on the display
If your scooter shows this error, it probably is a communication problem between controller and display. First step is to check the display, then check the spring wire (wire between display and controller) and then the controller (if possible with a multi-meter).
Error E3 shown on the display
If your scooter shows this error, it probably is an overvoltage issue, which means the charger or the battery are faulty. First measure the charger and if that’s not the problem, replace the battery (if possible with a multi-meter).
Error E4 shown on the display
If your scooter shows this error, it probably is a communication problem between controller and display or controller and battery. First step is to check the display, then check the spring wire (wire between display and controller) and then the controller (if possible with a multi-meter).
(Tip: Always note the exact error code before turning your scooter off—it helps us recommend the right part.)
2. Look for Physical Signs
Not every problem shows an error code. A quick inspection can reveal a lot.
Battery – If your scooter doesn’t hold charge or the range is much shorter than before, the battery may be worn out.
Tyres – Check for punctures, uneven wear, or loss of grip. Solid tyres may need replacing when cracked.
Lights / Display – Flickering lights or a dead screen often mean a wiring issue or display replacement.
Noises – Clicking, rattling, or grinding sounds usually come from loose screws, the folding mechanism, or the motor.
Throttle or Accelerator Issues – If your scooter doesn’t respond when you twist the throttle, or the speed is irregular, the throttle grip or wiring may need replacement.
Brake Sensor Error – Continuous beeping, sudden braking, or a scooter that won’t start could point to a faulty brake lever sensor.
Controller Error – If your scooter won’t power up, keeps cutting out, or feels unresponsive, the controller may need replacing.
Motor Error – Unusual noises, jerking, or complete loss of drive usually indicate motor problems.
3. Perform Quick Function Tests
Try these simple checks:
Does the scooter turn on normally?
Do the lights, horn, and display work?
Does the motor engage smoothly when accelerating?
Does the brake respond instantly?
If one of these fails, it usually points directly to the faulty part (e.g., display, motor, throttle, brake lever).
