This is true. Carrying a bike is extremely counter-productive in the woods. Unless you HAVE to to section hike through a piece of unrideable territory, it is best to find a spot to chain your bike up to a tree and come back for it. Any bike strong enough to carry touring gear is probably too heavy to want to carry with you while hiking. (Extra 20+ lbs, + tools and that's if your tricross is on the LIGHT side.)
That swiss army bike brigade is awesome. They need to bring that back. You can sneak up on a lot of **** quickly with police silent hubs. Covert Ops Cycle Corp would do some real damage.
