Carva
Encyclopedia
{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.{Primary source claim}}
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 cable
s 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.

Tricycle
A tricycle is a three-wheeled vehicle. While tricycles are often associated with the small three-wheeled vehicles used by pre-school-age children, they are also used by adults for a variety of purposes. In the United States and Canada, adult-sized tricycles are used primarily by older persons for...

Walking
Walking is one of the main gaits of locomotion among legged animals, and is typically slower than running and other gaits. Walking is defined by an 'inverted pendulum' gait in which the body vaults over the stiff limb or limbs with each step...

Running
Running is a means of terrestrial locomotion allowing humans and other animals to move rapidly on foot. It is simply defined in athletics terms as a gait in which at regular points during the running cycle both feet are off the ground...
