For me i much prefer it to motorbike touring. I like the physical challenge of bicycle touring and the fact you are fully immersed in the environment. Its sounds, sights, smells, the gradients, the weather and the people. On a bicycle you also have an intimate relationship with the land you pass as you are in touch with it's every curve, slope and contour. It's also quieter, cheaper, mechanically much simpler and more flexible.
