    A four-wheeled human-powered vehicle is called a quadricycle, quadracycle or surrey in the UK (after a British company that manufacturers this type of vehicle). The term was also applied to early four-wheeled motor cars but these obviously are not dealt with here.

    Some quadricycles designs like the Rhoades Car are clearly targeted at tourist applications specifically sightseeing (especially in warm and tropical climate regions) while others like the ZEM try to replace the compact car for urban applications. A family of four can journey together on these family tandems. The two-Seater EZ-1 SideBySide is actually comprised of two Sun EZ-1 recumbent bicycles with a connector kit created one chassis with coordinated steering.

    Thinking about car pooling to work? Why not commute with colleagues in a fun, eye-catching quadricycle? Note that most quadricycles exceed 1 meter in width and are therefore not suited for use on bicycle sidepaths.

    The Quattrocycle is well-suited to families and bike rental companies, with 2-, 4- and 6-seater models. The Quattrocycle features 4 independent internal hubs, allowing each rider to cycle at their own pace.

    The ZEM was designed and manufactured in Switzerland with 300 examples made. Its unique red mini-fairing running the length of the body has spawned imitations from Asian quadricycle manufacturers.

    Using PVC piping and connectors available at your local hardware store, salvaged 20" wheels and home tools, you can build your own quadricycle at fairly low cost and effort. Plans are also available online.
