This article is about small motorized four wheeled vehicles. For small four wheeled vehicles with pedals, see quadracycle.
The Quadricycle was an early form of automobile. Earliest models were propelled by a small steam engine, then designers switched to early internal combustion engines as they became available.
The word is derived from the fact that it had four wheels and used a lot of technology from the bicycles of the era.
