Recumbent [[tricycle]]s (trikes) are closely related to recumbent bicycles, but have three wheels instead of two. The three wheels can be arranged in two ways: delta trikes have one front wheel and two rear wheels, while tadpole trikes have two front wheels and one rear wheel.

====Handcycles====
{{Main|Handcycle}}
In order to accommodate [[paraplegics]] and other individuals with little or no use of their legs, many manufacturers have designed and released hand-powered recumbent trikes, or handcycles. Handcycles are a regular sight at [[Human Powered Vehicle|human powered vehicle]] (HPV) meetings and are beginning to be seen on the streets. They usually follow a delta design with front wheels driven by standard dérailleur gearing powered by hand cranks. Brake levers are usually mounted on the hand holds, which are usually set with no offset rather than the 180° of pedal cranks. The entire crank assembly and the front wheel turn together, allowing the rider to steer and crank simultaneously.

Although arms are weaker than legs, many hand cyclists are able to make use of the power of the whole upper body. A good hand cyclist can still achieve a respectable pace in competitions. Handcycles have also been used for touring, though few designers incorporate mudguards or luggage racks. Also, the gear ratios of standard handcycles tend to be less useful for long steep climbs.

==== Hand-and-foot recumbent tricycles ====
Recumbent cycles offer the possibility of combined hand and foot power inputs, and thus the potential for a full-body workout, and the option for persons with a weak or missing leg(s) to power a cycle. In one recumbent tricycle design the user makes the two front wheels change direction by shifting his center of weight, and moves forward by rotating the rear wheel.<ref>{{cite web |url=http://www.skywheel.kr/ |title=Archived copy |access-date=2012-11-06 |url-status=dead |archive-url=https://web.archive.org/web/20121025090056/http://www.skywheel.kr/ |archive-date=25 October 2012 |df=dmy-all }}</ref> There are also hybrids between a handcycle, a recumbent bike and a tricycle; these bikes enable cycling by use of legs, despite a spinal cord injury<ref>{{Cite web|url=https://berkelbike.co.uk/|title=BerkelBike – Cycle with your own muscles, in spite of your condition|website=BerkelBike}}</ref>
