Where can I buy a treadmill?

I suggest you buy it in a specialty store. Prices in shopping malls may be higher than those in specialty stores, and the size of shopping malls is limited. There are not many machines on display, but the scale of the specialty store is larger and there are more prototypes on display, which may provide you with more choices. If you are in Beijing, you can go to the stall at No.7 Tian Yue, Wei Zi, Xiaoying North Road, Chaoyang District. This is a specialty store specializing in treadmills, and a shopping mall of more than 300 square meters can provide you with more.
