ScooterCheck

Buying a used e-scooter? Stand next to it and tap Scan. ScooterCheck reads the battery, motor, controller and fault codes off the scooter over Bluetooth and tells you to buy it, look closer, or walk away: a 0 to 100 score and a ranked list of findings.

Free, paid for by a short ad while the report is prepared. No subscription, no account. Tap "See a sample report" to see a full inspection first.


WHAT IT FINDS

A tired battery: real capacity against the factory spec, with a rough replacement cost to negotiate with.
Cells that have drifted apart, the fault that passes every pack-level check and then cuts out under load.
A wound-back odometer, where battery wear and mileage disagree.
Demo-mode firmware, and speed caps that can never be raised again.
Plus fault codes in plain English, pack voltage and temperature, motor and controller heat, age and distance ridden.

Every deduction shows the reading behind it. A report built on too few answers will not call a scooter good, and when too little could be read to judge it fairly, it says Not rated instead of guessing.

Xiaomi's newest models, newer E-Wheels and NIU KQi are recognised, but keep their data encrypted or behind the maker's servers. The app says so rather than spinning.


READS ONLY

ScooterCheck reads; it never reconfigures. On Xiaomi and newer Ninebot, reading means completing the scooter's own pairing handshake: the app says so first, and one button press restores the owner's pairing.

No account, and the ad only tracks you if you allow it when asked. After your first report, you are also asked once whether inspections may be sent back to help support more scooters.
