If you: Have a two-part commute that combines a bike plus a train (or subway), ferry, or car ride
You need: A folding bike that rolls and handles well, whether over city streets or into a car trunk or an empty corner of a morning commuter train.
One to try: The Tikit Model T ($999) comes from Oregon-based Bike Friday, a leader in the folding-bike industry. The Model T compacts in about 6 seconds, has 8 speeds, and, at 24 pounds, is light enough to maneuver easily.
