Under Construction
I found several China English Tourist web sites very helpful. Travel China Guide was the one I used most and provided me with all my train tickets!
They have a section on most cites and train stations and the following about bicycle rental in Hongzhou, click HERE
It saya:
For renting a bicycle, one need a Transportation Smart Card T or Z. Z card is specially designed for visitors. It can be applied at the Smart Card Center at 20 Long Xiang Lu, Shangcheng District. You need to show your ID and store at least CNY300 in your new card. The Smart Card Center opens from 08:00 to 17:00.
Wonderful!
I spent many long hours following leads to a “tourist” and always ended up at something like this:
A closed kiosk?
Here is another one I spent a long time searching for and FOUND!
But again closed.
