Riding the Pendulum Bike

At the Pacific Science Center they have a bike that you can ride around a thin track about 4 metres above a pool.

Noisy video:

There is a safety net, but if you bail on the far side of the ring they will probably have trouble retrieving the bike since it is self powered. I guess they have a stick or something.

Even though you can't fall off the track (the weights below you keep you in place) it is suprisingly scary. I had to do it three times before we got the video right! See if you can spot where I wave.
