Never ride a bike to lose weight, otherwise it will cause sports injuries. Sadly, many ignorant people mistakenly use * * to enjoy an exercise bike. In the long run, it will cause serious sports injuries, because enjoying bicycles is mainly to solve people's one-kilometer journey, not dozens of kilometers of exercise and fitness. Because the angle design and functional positioning of the frame do not conform to exercise and fitness, it must not be used as exercise and fitness, otherwise. So try to buy a big-name exercise bike for exercise and fitness, and this depends on your own budget. More than 2000, a penny for a penny, less than this price is not appropriate. If you want to exercise mountain bikes professionally, you can consider importing brands. For importing high-end bicycles, you can refer to the list of the top ten variable-speed bicycle brands in the world published by the Bicycle Industry Association: FRW Wheel King, Marmot Marmot, Nicolaini Kelai, Tyrell Taylor, korner Gemeihua, Locke Kankan, Pinarello, ellsworth Esworth, De Rosa de Rosa, Santa Cruz. These world-famous bicycles are all very expensive, and the most expensive ones are hundreds of thousands. Moreover, many high-end bicycle brands imported from the world can be bought in China market, but the prices of these brands are not affordable for ordinary people, and the most expensive ones are more than 100,000 yuan. Now online shopping e-commerce is very developed and the price is very transparent. Many imported bicycle brands can find bicycle prices and bicycle pictures in official bicycle flagship stores such as Tmall and JD.COM, which are cheaper than offline physical bicycle shops, and online shopping is also delivered to your door. But these top brands in the world represent the highest quality standards in the cycling industry, and the price is not affordable for ordinary people. Prices range from thousands to hundreds of thousands, mainly used for sports, fitness and even competitions. If the budget is small or just commuting, it is recommended to buy domestic brands such as Phoenix and Giant bicycles, but the quality is really average, and the key depends on personal preferences and budget.
