Description

A two-wheel drive tricycle

technical field

The utility model relates to the technical field of tricycles, in particular to a hand-foot two-wheel drive tricycle.

Background technique

A tricycle is a vehicle transformed from a bicycle, which can carry people or transport goods. It was very popular after the 1930s, and then gradually replaced the position of the rickshaw. A tricycle is a combination of a rickshaw and a bicycle. The tricycle is divided into two parts, the front and the rear. The front part has a wheel that can be steered, the handlebar, the bell, the brake, the pedal and the seat, and the chain drives the rear wheel to rotate. The rear of the tricycle is mainly a carriage, which is a wooden semi-circle and can ride two people side by side. The cabin is fitted with a foldable rain cover with springs and two wheels underneath. Under the seat is a wooden box that can be opened to store the driver's tools and sundries. The seat has a cushion made of cloth and cotton batting, and there are footrests below. Tricycles can be divided into human tricycles, electric tricycles, children's tricycles and battery tricycles.
