Carva is a Lean Steer elliptical cross-trainer, human-powered, tricycle. Two wheels in the front and one in the back. Used to simulate outdoor walking or running without causing excessive pressure to the joints, hence decreasing the risk of impact injuries.

Carva offers a non-impact cardiovascular workout that can vary from light to high intensity based on the riding preference chosen by the user.[non-primary source needed]

Lean Steer[edit]

Steering mechanism actuated by degree of body lean and weight transfer.


Carva can be employed for many uses:

  • Recreation
  • Workout/Fitness

Carva uses standard bicycle brakes like: rim brakes, in which friction pads are compressed against the wheel rims; internal hub brakes, in which the friction pads are contained within the wheel hubs; or disc brakes, with a separate rotor for braking.

With hand-operated brakes, force is applied to brake levers mounted on the handlebars and transmitted via Bowden cables or hydraulic lines to the friction pads. A rear hub brake may be either hand-operated or pedal-actuated, as in the back pedal coaster brakes which were popular in North America until the 1960s, and are common in children's bicycles.
