Quick reprise, just to see if any info is available about the bike hire at Phra Pradaeng side of Klong Toei jetty. It seems one of the stalls on the jetty has a key to unlock a bike. Cost is 50baht/hour or 100baht/day. The bikes all seem to be single speed ladies style clunkers, with a carry basket on the front. I found a bit of a short cut from Klong Toei jetty back to Rama3.
I love cycling, whether rolling about in Bangkok or on country lanes. Recently I have also been attracted to bike racing as a means of challenging myself as I mature into that category known as The Elderly.
