What is a drive shaft?

A drive shaft is a rod which carries power from a bike’s engine to its rear wheel. Some early bikes, such as the Belgian FN of 1906, had drive shafts instead of belts or chains. The shaft turned the wheel using gears.

Amazing! In the early 1900s, women always wore dresses, even when they rode on motorbikes. So some bikes had a dress guard made of string which stopped dresses getting tangled in the engine or rear wheel.

What were leather belts for?

Most motorcycles today use a chain to drive the rear wheel. But many motorcycles made before 1910 used a thick leather belt instead. Belts were unreliable, as they wore out quickly, often broke and even slipped in the rain!

When was a drive chain first used?

Most modern bikes have a flexible metal chain which carries power from the engine to the rear wheel. Chain drives were introduced on some bikes in the early 1900s, such as the 1905 Scott. Chains are made up of dozens of short pieces linked together.

Is it true? Belt drives are still used today.

Yes. Most modern bikes use a chain drive, but some have belts instead. The belts are made from rubber, strengthened with fabric. Belts are lighter than chains and need less maintenance. A few modern bikes have drive shafts instead of a chain or belt.
