-Extreme Rollerman Video-
Jean Yves Blondeau is dubbed the Rollerman and as you can see in the video below it is for good reason.
It is not difficult for him to hit very high speeds but how does he slow down? If you watch closely at 1:16 you can see that he slides his wheels.
The knee and elbow wheels are mainly for steering but also double as his brakes as well. Therefore these wheels take the brunt of most of the stress as he soars downhill.
My favorite part of the video is the thumbs up from the police officers at 1:44! Well done Jean Yves!
