Introducing the Monowalker:
Although climbers, photographers and hunters would find this useful, the Monowalker is specifically geared towards hikers, trekkers and backpackers who want to hike without weight on their shoulders. Instead of busting your back and shoulders to the next campsite, the Monowalker places all of the weight of your equipment on your hips and on the back wheel of the contraption.
The makers of the Monowalker claim they haven't found one trail in the Alps that has stopped the Monowalker from following them - this includes scree and root covered trails.
The device even comes with disk brakes, allowing you to take a breather on steep inclines without having to worry about the Monowalker pulling you downhill.
Cross-country cyclists use trailers all the time to carry their gear. This is a logical extension of this concept. To me, this seems like a great idea, and potentially could get more people into the backcountry.
I bet this guy could make a lot money in Nepal with this!
