invented popularised both the velomobile and recumbent bicycle in the early 20th century. His velocars, are the forerunners of all modern velomobiles.
Most commercially available velomobiles are very similar to each other, with few layout variations. Most are 3 wheeled, normally with two wheels at the front (tadpole trike); only a few have a single front wheel (delta trike).
There are two main styles of velomobile: <!-- more -->
With an upright seating position, cab-style velos are comparatively tall, with an eye line at a similar height to a small car. They often have the shorter wheelbase of the two styles, because the rear wheel is brought closer to the rider's back. This seating position gives a taller body and screen.
With the rider seated reclined, the bullet style keeps the rider's shoulders in line with the highest point of his feet when pedalling. This gives a characteristic shape of a bulbous nose leading a flattened top and sides that taper towards the back. Either the rider's head protrudes just above the bodywork, or a bulged canopy is used to enclose them.

Alternatives exist to these forms. The Birk Butterfly does not have the wheels integrated into wheel wells that are typical of the bullet-style and they are mounted outboard in spats for reduced frontal area. In the Trisled Avatar Supervelo, the wheels are completely enclosed for reduced drag. Others have tried to move away from the bullet shape with alternative designs, like the Velayo.
