Battery and electrical safety. Lithium-ion batteries can catch fire if they're damaged or charged wrong. Never open a battery pack, and stop using any battery that's swollen, hot, wet or smells burnt. Every edit to this page is checked by a second person before it goes live.

This page covers common problems on Xiaomi electric scooters: the original Mi Electric Scooter (M365), 1S, Lite, Essential and Pro 2, plus the Xiaomi Electric Scooter 3 and 4 series. Xiaomi publishes separate FAQs for each model, so open the one for yours when a detail matters.

Before you start

  • Find your model and serial number on the label on the deck or control panel.
  • Keep the Mi Home (Xiaomi Home) app updated. Xiaomi's throttle FAQs list a firmware update through the app as one of the fixes.
  • Power off and unplug the charger before any check.
  • Do not remove the battery. The Mi Electric Scooter FAQ says doing so voids the warranty and risks electric shock.

Common problems and what to check

Scooter won't turn on

  1. Test the charger on its own. The Mi Electric Scooter FAQ says to plug it into the wall without the scooter. No light or a red light means the charger is faulty.
  2. Charge fully and try again.
  3. Think about storage. The 1S, Lite and Pro 2 FAQ says to recharge every 2 months when idle and not to ride below 5 percent. A deeply drained battery may need replacing, and Xiaomi says that damage is not covered by warranty.
  4. A dark dashboard can be a loose cable in the stem, per Xiaomi. Have a shop check it.

See e-bike won't turn on for general steps.

Won't charge

  • Check the thermometer icon. The 4 Pro (2nd Gen) FAQ says it means the battery is too hot or too cold, and charging may be blocked.
  • In the cold, that FAQ says the 4 Pro (2nd Gen) stops charging below 2 °C and allows it again at 5 °C. Bring it indoors and retry.
  • After long storage the battery may be over discharged. Xiaomi says to contact after sales.

Never charge a battery that is damaged, swollen, very hot or has been in water. Unplug it and take it to a pro. See battery won't charge.

Throttle does nothing

  • Kick off first. The Mi Electric Scooter FAQ says the motor starts at 5 km/h, and the Pro 2 and 4 Pro throttle FAQs say about 4 km/h.
  • Charge the battery and try another riding mode.
  • Clear any debris around the throttle and make sure the grip is not pressing against it.
  • Power off, wait a few seconds and power on again.
  • Update firmware in the app. Xiaomi lists a factory reset as a last resort since it erases your settings.
  • Code 14, or one long beep and four short beeps, means the throttle needs replacing at a service center.

More: throttle not working.

Brakes feel weak

  • Electric brake test from Xiaomi: lift the front wheel, power on, accelerate, then brake. The wheel should stop.
  • Mechanical brake test: power off, squeeze the lever and push the scooter. The rear wheel should resist.
  • The 1S, Lite and Pro 2 FAQ says to tighten the brake adjustment screw with a 5 mm hex key about every 6 months. The 4 Pro (2nd Gen) FAQ uses a 14 mm T handle socket on the screw rod nut.
  • See brakes.

Flats and tire pressure

Flats are the most common Xiaomi repair, and Xiaomi says most come from low pressure.

  • The 1S, Lite and Pro 2 FAQ says 45 to 50 psi front and rear, checked every 20 to 30 days. It also says to check tread at 3,000 km and replace a worn flat tire.
  • The 4 Pro (2nd Gen) FAQ also says 45 to 50 psi, checked monthly. Its tires are tubeless, so some slow loss is normal.
  • The rear wheel is usually the motor wheel and is harder to remove. The videos below show both ends.

See fixing a flat.

Error codes

Xiaomi scooters show a red wrench icon and a code on the display, and also beep. Count the beeps: each long beep is 10 and each short beep is 1, as the Mi Electric Scooter FAQ explains. Codes differ by model, so check your model's FAQ.

  • 14: throttle fault, needs a new throttle at a service center (Pro 2 FAQ).
  • 18: motor Hall sensor fault. Contact after sales (Xiaomi FAQ).
  • 27: main control password mismatch. Contact after sales (Xiaomi France FAQ).
  • 35: serial number still the default. Contact after sales (Xiaomi France FAQ).
  • 40: on the 4 Lite (2nd Gen), controller temperature sensor fault or overheating. Stop riding and get it serviced (Xiaomi FAQ).

Official help

When to get a pro

  • Any battery, charger, controller or wiring fault.
  • Codes 18, 27, 35 or 40, which Xiaomi says need after sales service.
  • A battery that runs hot. Xiaomi says the red temperature light means over 50 °C on the 1S, Lite and Pro 2.

Do not open the battery, flash unofficial firmware or try to raise the speed limit. Battery and controller problems belong with a pro. See battery care.
