Hiking up a hill is certainly a great workout, but once you’re up there – don’t you just want to get down? Check out the Bergmonch Bike Backpack – a 20lb backpack that also cleverly packs in a pseudo bike with it. The storage space within the backpack is mroe than enough to pack away water, change of clothes, food and even a bike helmet. Then when you are ready to descend the hill, just unfold the backpack into a seatless bike and ride your way down. The heavy duty tires are designed for off-road terrain, and it has built in shocks, brakes and a larger back wheel tire for control.
