Recumbent bikes with bodywork evoke a curious effect. They look as fast as a racing car or a jet fighter, but of course, they're not. Nevertheless, thanks to the recumbent position, the minimal weight and the outstanding aerodynamics, pedalling a "velomobile" requires three to four times less energy than pedalling a normal bicycle.
This higher energy efficiency can be converted felt in terms of comfort, but can also be utilised to attain higher speeds and longer distances - regular cyclists can easily maintain a cruising speed of 40 km/h (25 mph) or more. The velomobile thus becomes an excellent alternative to the automobile for medium distances, especially in bad weather.
