At one of our club's meetings once, we had a speaker that did an organized cross-country ski trip from Russia to the north pole. I'm sure a bike trip would be *as* possible, but it's not going to be the cake-walk you might think. Unlike the Antarctic trips of a few years ago, the Arctic is across ocean. The difference is, sea ice moves, creating ridges and yes occasional open areas. So you won't know ahead of time how many rough ridges you'll have to cross or detours you'll have to make. And the time window isn't as long as you'd think, unless of course you're planning on getting air-lifted back to land.

It would be a totally awesome adventure, though. For someone else. I like the cold, but only in small doses.
