As a necessary travel tool for newborns, every family has one of them. After a short period of use, it will always occupy space. Discarding and giving away people are not the best choice. This design is to solve the problem of how to make continuous use of the stroller. The "super variable" stroller can quickly switch between the walker and the stroller. After the modular shock-absorbing wheels and frames are added with accessories after use, more practical wheeled products such as strollers, shopping carts, shopping carts, etc. can be conveniently derived.
