- This article concerns sidecar as an attachment to a motocycle; for the alcoholic drink, see sidecar cocktail
A sidecar is an one-wheeled vehicle attached to the side of a motorcycle, producing a three-wheeled vehicle. A sidecar motorcycle is a three wheel vehicle with the sidewheel not directly aligned with the rear motorcycle wheel, and is powered by the rear wheel only. This is different from motorcycle trike, where the sidecar wheel shares a rear axle, and aligned, with the rear motorcycle wheel, and the vehicle is powered by the rear axle; or a motorcycle sidetrike, where the sidecar wheel shares a rear axle, but not aligned with the rear motorcycle wheel, even though the rear axle still provides power to the vehicle.
The sidecar consists of a frame (which is rigidly fixed to the motorcycle's frame on one side and is supported by the sidecar's wheel on the other side) and of a body. The body typically provides one passenger seat and a small trunk compartment behind. In some modifications the sidecar's body is used for carrying cargo only (like a truck's platform).
The sidecar's wheel is sometimes also driven (typically using a differential gear), to improve the vehicle's ability to go cross-country.
Before the 1950s, sidecars were quite popular, providing a cheap alternative to passenger cars; they have also been used by the army and police. During WWII, German troops used many BMW and Zundapp sidecar motorcycles.
Nowadays sidecars, for road use, are a mere curiosity. Some of the few remaining producers of sidecar outfits are IMZ-Ural and Izhmash in Russia, Dnepr in the Ukraine and Chang Jiang in China (all based on the same WWII BMW motorcycle). Sidecars are often seen on Russian and Ukrainian roads.
In Europe many sidecars are designed for racing competition. The sport also has a few followers in United States, Japan, Australia and New Zealand.
There are many small producers of sidecars in many countries.
