Whether you want to ride a business bike or a home bike, the quality is generally acceptable for business use, like Laimei's, and then it is safer and more stable. For home use, you can actually get a second-hand one from the American department, and then it's safer. If we are ordinary people, the wheel can be touched by hand, but in Laimei system, it has a shell outside, and then you stay at home to prevent children from disturbing you. Another point is that you should consider whether you can persist, not whether I can persist, but in fact, many people feel that there is no such gym atmosphere when riding. A lot of money, bought a piece of equipment, and then put it there as a decoration, eating ash.
