Very interesting site full of blogs from people touring on bikes: crazyguyonabike.com.
Particualrly interesting is the journal of a guy attempting to ride around the world on a penny farthing! Check his journal here.
Also found a lovely page dedicated to the history of Hectchings bikes. Some truly beautiful bikes there.
And check out bikeforest.com. Free bikeCAD software to design your own bike and wheels, links to supplies for frame building and a ton of links to quirky and interesting sites about bikes in all froms.
A bamboo and carbo-fibre mountain bike. Sweet.
Finally, you've probably seen this guy around the streets of Dublin on his weird front and rear steering bike, check out his site with some videos of him in action.
