Browsing through old photo archives we stumbled upon an image of a fun and smart transport device invented in the beginning of the 20th century. This was a single wheel accommodating one passenger-driver who looked so pleased with himself sitting inside his curious device that we couldn’t help but design one for our collection. We extended our research to find out more about single-wheel mechanisms and found ones that had no operator at all, developed as war machines and all covered in armor. What really inspired us was a similar approach to the transmission employed in all the prototypes starting in the 1860s: a moving outer element with a stationary mechanism inside.No armor shell included – your new Monowheel is built in skeleton steampunk style, which means you can see and enjoy the beauty of moving gears. Despite its airy delicate appearance, your new model is quite sturdy – you can take it outside and give it a good roll around on the pavement and other hard and semi-hard surfaces. The parts of the mechanism imitate a real steam engine. The lack of an outer shell grants easy access to rubber bands should you need to replace them. Two working modes guarantee even more fun. Mode one with the feet locked will give you uninterrupted rolling straight ahead for about 1.5 – 2 meters (5.0-6.6 ft) until the rubber-band motor’s resource is completely released. After that the model gracefully turns around and stops. Ages 14 & up. 300 pieces. Level: intermediate.
