KingSong

KingSong is a Shenzhen maker of personal electric vehicles that began with electric unicycles in 2012 and now builds scooters in its own factory, with in-house battery and circuit-board work.

Its US scooter range covers a 48 V folding commuter, two 60 V models with one or two 1,000 W motors, and a 50 mph dual-motor flagship with a removable pack. Most carry front and rear suspension, turn signals and app control.

Scooters ship free from US warehouses with 30-day returns and a one-year warranty on the battery.
