In general, a bicycle is often used as a vehicle for a passenger to ride on a pedal and is convenient to move and store. In recent years, the use of an electric bicycle using a motor is also increasing.
In general, bicycles are composed of front and rear wheels only. It is difficult for passengers to concentrate on the bicycle. Recently, it is easy for beginners to ride, and for safety and convenience, A three-wheel bicycle that can be used has also been produced and distributed.
Generally, a bicycle having a pair of rear wheels is called a three-wheel bicycle, and a bicycle having a pair of front wheels is called a reverse bike.
Dual reverse bikes have been used for many years because they have the advantage of securing the stability of tricycle and stability of speed, cornering and riding comfort which is a disadvantage of tricycle. ought. Korean Patent Laid-Open No. 10-2010-0125587 (wheel width variable type reverse reverse bike), Korean Patent No. 10-1801159 (a pair of front wheel width adjustable reverse bike), Korea Patent No. 10-1799554 (Reverse osmosis bicycle equipped with external shock absorber), Korea Patent No. 10-0941319 (reverse osmosis pitched bicycle that is tilted at the same time as steering) Various improved reverse bicycling bicycles are disclosed.
However, the conventional reverse bicycling bicycle has a disadvantage in that it is inconvenient to mount or store the vehicle because the reverse bicycling bicycle has a bulky structure as a pair of front wheels.
In addition, reverse bicycling bicycle has a three-wheel structure, so it can be used only by bicycle even though it can stand itself without being overturned.
