The 1938 French Lehaitre tracked motorcycle was named the “tractor-cycle” by the inventor. The vehicle was said to be superior to an ordinary motorcycle in its ability to climb steep and rough grades-although its speed on level ground was limited to about 25 m.p.h. Steering was accomplished by handlebars which control a sideways motion of the drive belt.
