After a ride, the legs and resistance unit fold and the PowerBeam collapses small enough to store behind a sofa. Syncing the computer control unit to the PowerBeam is a simple five-minute process.

It’s quick and simple, and the Revolution creates a remarkably solid foundation. It does not, however, collapse.
