Can I rend and ride bicycle in sightseeing areas for leisure in Shenzhen?

I remember there are bicycle tracks in the city and you can easily find bike rental points in SZ.
I also heard you need to get a special rental card for bicycle. In different districts, the fee standards are different. In most districts, it is usually free of charge for the first hour.
It is suggested you give me your exact location and then I can tell you what is the nearest place to get the rental card and the specific rental.
