One of the many cool things about working in a bike shop is getting to see cutting-edge bike stuff before it becomes trendy and hip. Below is a fine example I found in a remote village in Nicaragua last week. This design securely holds your trusty mach trusty machete while avoiding that awkward and unsafe situation of trying to ride with it across your handlebars. I learned from experience that they are razor sharp when using one to harvest plantains a few days later.
Also note the clean and uncluttered design of the bike sans front derailleur, brakes and associated cables that just get in the way. It makes sense when you realize that the nearest bike shop is 1 1/2 hours away or by car or 4 hours by bus. Braking is done either Flintstone style or by placing opposing foot bottoms on the front tire.
