Electric scooter for parts NOT FREE ( sensor failure )

Bought this in January and it just recently stopped moving sometimes the screen will display a error code (E15) meaning a brake sensor failure. This would be a little project for someone that knows or is learning to repair e-scooters/ bikes. Battery is in perfect condition. Motor can go 25km/h Scooter has a 25-28 km range on a full charge. Please message me and we can work out a price
