My prefered videos : “Inspired Bicycles – Danny MacAskill”
This video is 3 years old and the quality is not so good (no HD available).
I still watch it time to time as it is really very cool.
It’s about a (crasy) guy that does crasy things on his bicycle.
Do not forget to switch on the sound, the music is very good.
Breathe, relax and enjoy !
