I wouldn't reccomend the smaller Dahon's. Because if your a trucker riding somewhere. We see a lot of chuck holes and often you will have to ride along the very rough edges of the pavement to avoid the high speed and often reckless drivers car traffic. These smaller wheels get very unstable at the higher cruise speed you might like to run. It gets pretty frustrating when you want to go 5 miles or more and you have to run slower due to rough pavement, or gravel or whatever. You have to pay closer attention to the holes, when you are running smaller wheels on your bike. For a while back before kids and pocked bikes were around. I bought a Go-Ped big foot and run it on the road. I'm an adult and the cops seen me alot on the road and never bothered me then. Probably couldn't do that today. But anyhow, I had an letter to my girlfriend to mail out. ( my wife today ). I got going on my big foot to the post office. THey have something like 10" wheels. A split second mistake of not seeing a pothole. My front tire went it and I instantly went over the handle bars on asphalt going about 12 mph. Body slammed on asphalt at 12mph hurts real bad. Right in the middle of the street. I was wearing shorts and my knee was dripping with blood. WHen I got up I noticed a cop was parked over to the side and witnessd the whole wipe out. I got up quickly and limped to the shoulder of the road dragging my go-ped with me. THe cop then pulled away. I was glad he went on but I was in some real pain for a while. I strongly feel a regular bike hitting that hole would not have caused a wipe out due to the large 26 wheel would have spanned the hole better.
