A cycling chair, as known as a pedal wheelchair, is a human-powered (or gravity-powered) vehicle.

Cycling chairs are used primarily for recreation, shopping, and exercise. Cycling chairs are favoured by children and senior adults for their apparent stability versus a bicycle. A conventional Cycling Chair is usually designed for walking speed (about 5-8km/h). Most of the Cycling chairs have 3 or 4 main wheels, as well as anti-tip support wheels. The main difference from tricycles is, to have a wide seat surface, usually in rectangle shape, like a chair, mostly with back support as well. The riding posture is usually upright to tilting back, opposed to tilting front in case of tricycle.

the one I saw on youtube in the USA. put the handle-pedal part in front of the traditional wheelchair, so that the legs can be passively moved together with the locomotion

Many of them use chain structure. Front wheels are the driving wheels. take care when cornering to avoid tipping the trike over. Unconventional designs such as recumbens have a lower centre of gravity so require less care.
