BBC4 have done a series of 2 hour videos of journeys, no music, no commentary, just amazing views. There was one of a canal trip, which I didn't enjoy, but I actually watched quite a lot of a trek through the Arctic by a group of Sami with reindeer sledges, which was good for the complete silence apart from the thudding of hooves on packed snow, the long Arctic dusk and lack of talk amongst the reindeer herders who were completely at ease with each other and the environment of the tundra.
I don't think somebody else's bike ride would have the same mesmerising effect!
