NIce to see old traditions kept alive, lots of towns here in Cambodia still have "cyclos" as they're called here. I actually was a cycle rickshaw driver in Colorado for two years in my younger days, but carrying up to three and four people in a town with a slight slope destroyed my knees. I totally understand why these guys rarely take more than two folks around.
I'm old fashioned, even here in our village all the locals laugh at my family and I because we ride a Honda Cub 90 and 50, bikes that are considered too slow to climb the mountain pass we live on.
