Foldable, speed range of 60-80 depending on weight, can operate for a full charge of about 30 to 40 km. It has Bluetooth, a start key, and a remote control for remote operation, along with a security system that locks via the remote. It also has pedals so you can use it as a regular bike for exercise. I have only used it for two weeks intermittently. Please, only serious inquiries; everything is clarified in the ad.
