Now here’s an awesome idea: AWD bicycles (two wheel drive, in other words). When mountain biking up steep grades with a normal bike, you have to lean forward to avoid doing a wheelie, but balance your weight carefully between the forward and rear to keep traction to the rear wheel. There have been many times I’ve ended up either walking my bike up really steep sections, or tried to keep riding but ended up losing traction and totally biffing it. I can imagine an AWD bike would make these steep grades much easier.
