It's a revolution in cycling! The deciding battle in a contest to develop a bike that won't tip over, even when it's just crawling along: The Super-stable Bicycle. The contestants are an artisanal bike maker whose atelier has been in business for half a century, and an expert in the latest robotics. Which custom-made, experimental bicycle will travel farther, at slow speed, down a course 50-centimeter-wide and 50-meter-long, with a rider who is allowed neither to pedal nor to use the handlebar to steer? Who can produce that miracle: the craftsman who has dedicated his life to the perfection of the bicycle, or the scientist seeking a safer, self-balancing, 2-wheeled vehicle under robotic control? It's a fight to the finish!
