I bought a used Dahon Jetstream P8 2007 and rode it around quite extensively as a commuter in Bangalore, India. While the bike rode very well, the derailleur hanging off the bike was very inconvenient when folded. So I decided to convert it into a SS.Took the easiest approach possible - retained the freehub and used a Gusset Single Speed conversion kit along with a Gusset Bachelor Chain Tensioner to replace the Cassette and to achieve the right chain tension.

Love the way it rides!
