The inspiration for El Bolso comes from the bags used by farmers in El Salvador, the home country of our bag designer. El Bolso is incredibly easy to use: unfold it and lay it on the ground, place the bike in the middle of the bag, pick up the sides of the bag, and sling it over your shoulder. The entire operation takes only a few seconds - just what you need when you are rushing to catch a train. When you are riding your bike, El Bolso rolls up to pack into its own bag that slings across your shoulders. Made from IronGrid nylon. One size fits all Dahon bikes.
