Impeccable condition. It is a functional scooter in perfect condition for small to medium sizes The bluetooth application is called Tuya and is available in the description of the scooter, just scan the QR code and install. . I weigh 50kg fully dressed I climb the odds in eco or drive mode for the steepest and longest ones. For a size of 65 kg switch to sport mode for the dimensions. It is a utility for driving in town and light for possibly taking transport. I ordered a 2nd refurbished scooter. I think the transport may have disrupted the rear wheel, it was rubbing all the way and the rear wheel wasn't turning. I unscrewed the BTRs from the brake caliper very slightly with an Allen key then repositioned it so that the wheel no longer rubs and tightened the BTRs. I tested it's nickel.
