What does an electric scooter speed limiter wire look like UK?

The speed limiter wire on UK electric scooters is typically a green, white or black cable that loops from the controller back to itself. In electric scooters like the Xiaomi Pro 2 or Pure Air Pro, the speed limiter consists of two white wires (often with yellow heat-shrink tubing) emerging from the controller - usually located under the deck or near the battery compartment. The controller acts as the scooter's 'brain', managing motor functions including speed regulation. Most UK-compliant e-scooters have these limiters fitted to meet the 15.5mph legal speed restriction.
