The concept

The Electroller is an inline skate equipped with an electric motor powered by a removable battery pack.


When I imagined the Electroller © concept, I was thinking about adding power to inline skates. I wanted to create 4WD skates that could make it easier to climb hills… And then I thought : why not use the worm gear drive to slow or stop the skates too? It’s difficult to brake with one foot tilted in the air… this drive makes it possible to brake all four wheels without loosing grip on the ground.

How it works

The wheels on the Electroller are powered by a small electric motor. The motor is connected to a gearbox that turns a worm shaft located along the longitudinal axis of the skate under its sole. Each inline wheel is attached to a worm gear linked with the worm shaft.

The operator thus apply power on the wheels to accelerate, slow down or immobilize the skate. The worm drive can also be used without any motor to slow down the skate, it would simply be connected to a mechanical brake or disc brake operated by the user.

What it’s used for

The Electroller can be used as a means of transportation for longer distances than regular inline skates. It can also be used to visit parks or take long rides along cycling paths.

The designer

I would like to thank Boris Schwarzer for creating the renderings of the Electroller concept. Boris is based in Michigan, U.S.A. He went to the College of Creative Studies. He also created the images for the Spike commuting car, the Joust personal transporter, and the Urban Link tuk-tuk.
