I picked up a 'Dahon' boardwalk single at Performance yesterday. It says 'Dahon licensed technology' on it, so I suppose it is not really a Dahon. In any case, it seems like a pretty good bit of bike for $145 + tax. I would think that it is made in the same factory as the Dahons. A rack and fenders would normally cost $50, it's like getting the bike for $100.
These comments are in response to issues that came up in other posts:
Handling is fine. You can ride no hands and track stand. It is a little goofier than a bigger bike, but it's surprisingly good.
Ride is definitely harsher w/ the small wheels. I don't know what Performance pumped the tires to, so that may not be fair.
Ergonomics feel pretty good to me (5' 9"). It did feel like the seat is too far forward, though. It's adjusted pretty much all the way back on the rails.
I wouldn't want to replace a full size bike w/ this thing, but it seems like it will be fun to travel with, and great to keep in the car.
Wheels were pretty true out of the box and spokes are all tight. Hubs are not real smooth - oh well, not bad for the price.
Frame is plenty stiff for out of saddle single speeding.
