YouTuber Colin, who is renowned for his inventions, including the world's fastest mobility scooter and longest motorbike, decided to build the treadmill to get fit, instead of going to the gym. He made the machine using a three-metre-long treadmill belt attached to a wooden frame, with adjustable rollers on each end. The treadmill is powered by an electric wheelchair motor and two car batteries and has four speeds, with a maximum speed of eight miles per hour.
After all, maybe this isn't such a great idea. lol
