Urban Performance: Dahon Mu Ex

Readers know that we’re fans of Dahons and folding bikes in general. We’ve ridden them all over the Pacific Rim in our travels and hang with the Dahon crew when we’re in Taipei.

I suspect Dahon heard our insistence that they lighten up their bikes, cause they built a super light one, and equipped it with SRAM Red components.


I first rode the Mu Ex during SXSW and took it with me to Portland. A pleasure to ride, the bike is responsive, fast, and performs.

Best part is it climbs … for reals. With the Ergon grips (also has the built-in Seatpost pump) and bar ends, you can use your whole body to grunt up the steepest hills.


It’s been a mystery to me why weight hasn’t been on the minds of product managers of folding or urban bikes. It’s not just roadies that can appreciate a 20 pound bike; especially on the steep climbs when it’s loaded up for the commute. Taking 5 pounds of a bike makes an enormous difference in the travel load and overall performance. In its category, the Mu Ex is hard to beat.

Next refinement we’d like to see is a mechanism to better hold the bike together when it’s folded.
