Bicycle touring in Norway in 1890... so Bikepacking is not really new.
Ok, I'll bite - of course no one is claiming that strapping things to your bike and traveling is anything new. And I suppose there is a semantic debate to be had as far as where "bike touring" ends and "bikepacking" begins (and there is plenty of middle ground in between), but as much as I love that classic photo, those guys were not riding the kind of terrain with those setups that a modern mtn. bike, with a lean bikepacking kit, allows one to cover over multiple days. In my mind at least, the point of the "bikepacking" approach is that it allows one to travel on a bike in places that would have been very difficult if not impossible with a traditional "touring" setup.
Such as....
or....
There is no way I would have wanted to be on a skinny-tired bike with panniers or other huge bags strapped to my bike when I was on the trip above. So, no - I don't think bikepacking represents anything radically new. But it
is a different approach than traditional touring gear, which makes a lot of sense when applied to terrain that calls for a lighter, leaner approach.
But in the end, who cares. Ride your bike and explore and carry your gear in whatever way makes the most sense for you and the conditions you ride in.
