In 2003, Tom Wiberg from Sweden built a motorcycle with a front wheel diameter of 16 mm (0.62 inches) and a rear wheel diameter of 22 mm (0.86 inches). He rode it for more than 10 m (32.8 feet) in Hökerum, Sweden. The motorcycle has a wheelbase of 80 mm (3.14 inches), a seat height of 65 mm (2.55 inches), weighs 1.1 kg (2.4 lbs). It powered to a top speed of 2 km/h (1.24 mph) by its 0.22 kW (0.3 hp) engine. In my opinion, this was built by the designer just to obtain the Guinness World Record for the World’s Smallest Motorcycle.
