Description
Technical Field
The invention belongs to the technical field of bicycle accessories, and particularly relates to a bicycle seat capable of being freely switched by one person and two persons.
Background
China is a bicycle of China, and has great problems in energy consumption and environmental pollution while bringing convenience to traffic due to the rapid development of the automobile industry. Along with the improvement of the living standard of people and the enhancement of health and environmental protection consciousness, the bicycle can not be reduced due to the development of other vehicles. The bicycle has the function of being irreplaceable by other vehicles as a short-distance riding instead of walking. The bicycle is an important transportation means for people to travel daily, and a plurality of parents use the bicycle to pick up children for learning, so that various bicycle seats are designed for the people and are divided into a rear bicycle manned seat and a front bicycle manned seat. Most of rear-mounted bicycle manned seats are of flat plate type, can carry people and things, are convenient and wide in application, and are common people carrying seats. However, when a child sits on the bicycle backseat, the two legs are in a hanging shape, and the child has no fixed armrests, so that the fear of sitting on the bicycle is increased, the two feet are easy to roll in the wheels, accidents are easy to occur, and the two legs are in a hanging shape for a long time, so that the joint is loosened, and the child in the growing period is not beneficial to healthy growth of the child. Most of front-mounted bicycle manned seats are directly fixed on a bicycle frame, so that children, old people and disabled people can travel conveniently, and the front-mounted bicycle manned seats are also very suitable for leisure travel. However, the front bicycle manned seat is low in use frequency, is fixed between the seat and the handle bar, prevents riding of a rider to a certain extent and causes the bicycle to lack of integrity and be unattractive.
