The powered skates each have an extended chassis which is either attachable to or built as part of the skate. The chassis supports an electric motor (or cylindrical female receptor for cable drive) and driven wheel at the rear of the boot with a swingarm attached at the axle thereof and the heel of the chassis. The driven wheel maintains hard contact with the road surface by way of a spring mounted between the motor/receptor and the upper part of the chassis. Motor and wheel move together in a vertical plane. The driven wheel is aligned laterally with the four wheels of the inline skate. Power to the wheel is automatically cut off when the powered wheel loses contact with the road surface. Where there is an electric motor, the power is provided by rechargeable batteries worn on the waist or back of the skater in the form of a belt or backpack respectively. Acceleration and braking are controlled by handsets that are integrated with the wrist protectors often used by skaters. These each have a pistol-type lever which, when squeezed, progressively implement acceleration (right) and braking (left). A cut-off override button/lever would be provided as an advanced feature. The belt/backpack can be plugged in to recharge the batteries, and the transfer unit at its centre, by way of internal levers and circuits, ensures the efficient transfer of "commands" from the hands to the motors and wheels.
