Denver bike-share firm B-cycle has set up a demo station at Pier 84 on the Hudson River Greenway. Reps should be there until around 5:00 today.

B-cycle is a cooperative of Humana, Trek, and PR firm Crispin Porter + Bogusky. On Thursday it will launch a 500-bike program, billed as "the first city-wide bike-sharing system in the U.S.," in Denver.
