The main source of profit in mobike is the deposit paid by users, and the deposit in mobike is 299 yuan. Although users can refund the deposit at any time, many users have already paid the deposit, so for the convenience of riding, they generally will not refund the deposit. So with the increase of users, mobike has accumulated more funds.

There is also the fare paid by the user. In mobike, the charging method is 1.5 yuan per hour, and less than one hour is also charged according to this standard. Generally, people who use bicycles are students' parties or office workers, and ride them once or twice a day. Therefore, mobike can also get a lot of income through this calculation.

Then there is the investment of enterprises cooperating with mobike. We can see the logo of mobike from the small programs of WeChat and Alipay, which shows that mobike has cooperation with these big enterprises. Therefore, mobike will cooperate with other enterprises to attract financing, which is also an important way for mobike to make profits.
