Rollkers is a personal transit accessory; the idea is that it is like gently gliding forward at about twice normal walking pace with no additional effort.
Walk faster - Rollkers is a transportation accessory that increases a person’s average walking rate up to 7 miles per hour.
No training needed - Unlike inline skates, Rollkers are immediately balancing and require no specific training.
Self sufficient Battery - Rollkers were developed to provide a healthier, more environmentally friendly form of transportation.
Carry them with you everywhere - Small and light devices make them easy to carry anywhere, anytime.
Fits all sizes of shoes - Totally hands free: “Auto-Clipping” on and off any size and make of shoes.
Regular Technovelgy readers know that I cannot resist the Hugo Gernsback reference - tele-motor-coaster from his excellent 1911 novel Ralph 124c 41 +!
In reality they were Tele-motor-coasters. They were made of alomagnesium and each weighed only about one and a half pounds. Each had three small, rubber-covered wheels, one in front and two in the rear. Between the wheels was a small electric motor - about the size of a lemon; this motor could only be operated by high frequency currents and, despite its small size, could deliver about one-quarter horsepower.
