I stumbled into Nok's brand new shop. She gives bicycle tours through Bangkok. They just got brand new Mountainbikes a view Days before I was there. I took the night tour and it was really nice. It's a little adventurous to ride a bike through Bangkok at night. But to go to the temples at night is awesome. A whole very different atmosphere. And Nok knows a lot bout the city and the history. So, I liked it a lot. Best of luck.
