The balance principle of cycling

So in the folk, people began to self modify and make various small balance bicycles suitable for children's cycling, including wooden, steel wood mixed, thick iron wire bent, and bicycle modified bicycles, all in full bloom, but still not enough meaning: some are not suitable for children's body shape, some are not safe, and some are too bulky. In 2003, an institution in the city of Vilfrat, Germany, collaborated with the University of Frankfurt for more than two years to develop a carbon steel frame balance car that was integrated into a child's ergonomics system, creating the basic framework for a child's balance car. To distinguish the Laufmachine adult balance car, the Germans gave the children's balance car a more vivid German name Laufrad, meaning "running wheels". The children's balance car has also become a popular baby bike among German children.
The study by the University of Frankfurt succinctly explained the balance principle of cycling to parents, and also demonstrated that children's balanced bicycles can also be balanced for cycling without the need for chain transmission. Children's balance bikes can not only exercise their balance ability while riding, but also choose solid EVA tires or inflatable rubber tires based on children's ergonomic data such as age, height, and leg length. They can also choose different colors according to children's preferences, which can be said to be a lot of fun and educational. Due to these professional choices and exercise benefits, the children's balance bike Laufrad has rapidly become popular around the world, with many English names such as Learner Bike, Balance Bike, Running Bike, and Chinese names such as children's balance bike, roller coaster, and scooter in China. However, children's balance bike is still the most mainstream name.
