SpnKIX: Electric roller skates

We already show you fuel powered rollerskates, here is an electric powered model! The concept is a bit greener, but still quite cumbersome. We owe this invention to the American Peter Treadway. These skates could reach 10 mph (16 km/h) with a range of (only) 4 km.
The charging time: 2 hours.
This model is intended to be used with any pair of shoes, like the old roller skates. Micrometer straps are stalling the foot.
The SpnKix are controlled by a wireless remote that regulates the speed. The structure of the shell consists of nylon and fiberglass. Each skate is equipped with a motor and a battery.
They come with removable training wheels so anyone can master them easily.
