ScooterCheck

The seller says the battery is fine. The battery says otherwise. Scan any used e-scooter over Bluetooth and hear its side of the story before you agree on a price.

Never buy a used e-scooter blind again. Stand next to it, tap Scan, and ScooterCheck reads the battery, motor, controller and fault registers straight off the scooter over Bluetooth, then grades what it found and tells you whether to buy it, look closer, or walk away. Scanning is free, so you watch it connect to your scooter before you pay anything.

HOW IT WORKS

One tap. The app finds the scooter, connects, reads every register the firmware exposes, disconnects, and reports. You get a plain-language verdict. "Looks solid", "Worth a closer look", "Walk away unless the price reflects it" backed by a 0–100 health score and a ranked list of findings.

SEE IT WORK BEFORE YOU PAY

Scanning costs nothing. Tap Scan and the app connects, tells you which scooter it found, and shows how much of it answered, all before any paywall. So you never pay to find out whether ScooterCheck works with your model. You unlock the score once you've watched it talk to your scooter.

WHAT IT CHECKS

Battery: measured capacity against the model's design capacity (state of health), pack voltage at charge, cell temperature, charge level. Wear: calendar age from the detected model, total distance ridden. Faults: active error and warning codes, decoded to plain English where the code is known. Configuration: speed limit, firmware version, showroom/demo-mode firmware. Drive electronics: motor and controller temperature.

Every deduction is shown with the raw reading that caused it, no black box.

WHAT IT CATCHES

Tired batteries. A pack at 62% of its design capacity gets flagged as a major finding with a rough replacement cost, so you know what you're negotiating over.

Wound-back odometers. If the measured battery wear doesn't match a suspiciously low mileage, the report says so, on brands where the odometer is known to be rewritable.

Demo-mode firmware. Some scooters get left in the showroom mode dealers use, which quietly limits what the scooter will do. Invisible while riding, and disqualifying if you're paying full price.

Permanently restricted speed. On some hardware a lowered speed cap is a one-way ratchet that can never be raised again. Not a setting, a permanent reduction in what you're buying.

HONEST ABOUT WHAT IT CAN'T SEE

Every report carries a confidence rating: how much of the scooter actually answered. A scan that couldn't check faults or drive temps never earns the same clean bill as one that checked them and passed. A scooter that hides data scores lower, not higher, opacity is a finding too. There's a "what we couldn't check" list, so you always know where the gaps are.

FACTORY SPEC SHEET

For 24 catalogued models, compare the scooter in front of you with the one that left the factory: measured capacity against design, top speed against the factory rating, and the years the model was sold, so "barely used" gets a date check.

SHARE THE REPORT

Selling instead of buying? Export the inspection as a square image for your listing. A scored, timestamped report beats "battery is fine, trust me".

READ-ONLY, ALWAYS

ScooterCheck never writes to the scooter. It reads, scores, and disconnects. Nothing is changed, unlocked, tuned or reconfigured. You're inspecting someone else's property, and the app treats it that way.

Everything runs on your phone. No server, no account, no analytics, no ride history, no network connections at all.

PRICING

One-time purchase, no subscription, no ads. Unlocks the health score, the full breakdown, the spec sheet and the shareable report.
