What are your favorites spots or routes in the city or in the surroudings??Just cycling on the main streets seems be too dangerous...

Along Sukhumvit (heading towards Samrong) to Bang Na intersection, turn right at the intersection and head down Sampawuth Road as far as you can go. At the temple by the river take the ferry across the river for 5 Baht (ferry is for foot traffic, motorbikes and pushbikes only). Cycle around in the greenery of Bang Krachao to your hearts content and then retrace steps back home. On Saturday and Sunday there is a market (worth a visit) that brings in mainly Thai tourist traffic, but other than that it is peaceful, apart from a few dogs which do not like bikes. You do not even feel you are in Bangkok or its environs. Lovely place and the people are really friendly - especially to cyclists which they are trying to promote the area to.

you can also cross at Khlong Toei harbour, that one is 20 baht and you need to put your bike on a smaller boat. The Bangna crossing is the most comfortable but might be a far way if you live closer to the center.

For favorite routes check out the OSM bicycle map, all the blue lines are pretty nice for riding. Personally i like the elevated concrete pathways along the klongs all over Bangkok, specially east towards Suv. airport.

Nice to see OSM cyclemap growing in BKK. It still needs helping hands who are willing to collect data and/or map it. Still a lot to do in Thailand

If someone do not know OSM but is interested: Have a look at http://wiki.openstreetmap.org/wiki/Main_Page

If you have children and want to do a safe ride with them you may want to try Rot Fai Park. You can rent bikes there at the parking lots in the north of the park.

I like riding at the klongs too. But it can be dangerous. And better not do it with clipless pedals. Falling into water while clipped in can become a very bad experience

If you can access Facebook, the Freewheel Bangkok page offers information and links that may be useful

and some interesting photos - though I am not so sure about this one:

Well if you head to the north of the city, its accessible courtesy of KampengPhet 6, that's the side road to Vipawadi Rangsit. 4 lanes, little traffic and quite a few things to see, good surface as well. It will take you all the way from the backside of Mo Chit Mai to Rangsit and beyond. I always see lots of cyclists on it as Vipawadi takes 90% of the traffic. Very nice road to cycle along. Basically, its the other side of the train tracks to Vipawadi.

Another nice location is "Bueng Nong Bon" and "Rama IX Park". Not all paths are open for cycling in Rama IX Park, but there are a lot of cyclists riding in circles on this circle course. You can do a good workout there.

I will have to try out some of those routes on the OSM cycle map. There are a couple down Onnut that would be an interesting diversion on my way to Chachoengsao. Hopefully it will be cloudy next Saturday or Sunday. Yesterday was a bit too hot so stuck with Bang Krachao.

Rot Fai Park... at the end of the BTS near JJ Market

4km loop that you can ride around, I would suggest not going late afternoon/early evening... but after 9am to 2pm is good or after 6pm.
