You should let the management know.

We have Keiser spin bikes with magnetic resistance at our fitness center. They've been there a year and seem to hold up pretty well. It's rare that one is out of service. I'm off the road bike due to a couple of crashes and related issues for a while and really appreciate the ability to get in a good workout.

Our center is currently doing a program where the spin class rides simulate each stage of the Tour. You get assigned to teams, and each team tries to see how many classes they can ride over the three weeks. LOTS of women in the classes, and a room with about 40 bikes has about 20-30 in use each class. They probably have about 25 classes a week too.
