I don't know, the Pugsley comes from from a college and his brother. They are quite extreme when it comes to bicycles.
Both of them own 7-10 bikes each including a couple of pugsley's and a moonlander.
It is a bike they build from spareparts they had laying around.
It is a borrow as long as you like, but if you break it, you buy it.
Btw. they both ride fatbikes with rohloff hubs and will never go back to derailleur, because it is much more reliable in crappy conditions.
