Last year, I sold my mountain bike, which cost me more than 2000 yuan, to others at the price of 500 yuan.

1, from the perspective of "investment and purchase" alone, it is a "huge loss", because if you buy a new car now, it will cost another 2,000 yuan. . 2. From another point of view, there is no loss: first, it is to spend money to buy lessons. The ancients taught "prepare for a rainy day" and were far-sighted. Don't blindly follow the trend and listen to other people's suggestions (in recent years, many people who invest in bicycle sharing have lost their money because China people like to "join in the fun" and "short-sighted behavior"). Bicycles are the current means of transportation. Even if you buy a car, it is also a good tool for exercise and fitness (learn about cycling fitness online). It is not appropriate to throw it away. This is true of many things in life and career. Secondly, if the color of the car with 2000 yuan is relatively new, it is almost half price, and 900 yuan is acceptable. Selling 500 is a price jump, so I'll deal second-hand, and get to know the market first. How much do you sell other colors? They sell it at this price. Can they sell it? Then set a price yourself to avoid "huge losses." Third, you should understand that bike sharing and mountain biking are not the same thing, and the riding experience is completely different, especially when going uphill against the wind. The geometry is wrong. Cycling for a long time will hurt his knees and waist.
