When Dahon released the widely popular Mu Uno folding bike they found that the simple one-speed design was widely popular with urban commuters. It's simple, lightweight, and even looks cool. The Dahon Speed Uno folding bike is a newer, simpler design that is even more affordable. At 24 lbs, the Speed Uno folding bike is one of Dahon's lightest bikes. One of the reasons for this is the single speed with a rear coaster brake. Just like the bike you had when you were a kid, pedal backward to stop the bike with a skid. Folding and unfolding has never been easier or more secure!
