Gulak put off college for a year (now 19, he enrolls at MIT this fall) and began building the Uno at a motorcycle shop outside Toronto. He modified the frame from a Yamaha R1, which is wider than most motorcycles, so it can house the side-by-side wheels. But he quickly realized that he was out of his depth in the electronics department: He would ride the Uno for a few seconds, and the circuitry would catch fire. So he contacted Trevor Blackwell, a robotics engineer who specializes in self-balancing software. With Blackwell's help, Gulak equipped the Uno with a gyroscope and a control system that both keeps the rider balanced over the tires and manages the suspension.
