The following link: http://www.youtube.com/watch?v=I13wJyUZL_4 has a man limp to a bike (a Pinarello) leaning against a wall, climb on to it and ride the bike for a good minute to a minute and a half, while remaining stationary. My question is:
What is the simulator like device called? It looks like a bike treadmill, but what is it called?
How does the bike remain stationary on that device for all speeds? I would imagine that the bike would be stationary for only higher speeds, but that does not seem to be the case.
What are these devices used for?
Any insight on the above is most welcome.
