If you: Don’t have a car
You need: A bicycle that thinks it’s a station wagon.
One to try: Oakland’s Xtracycle’s Radish ($1,199) indeed looks like no other two-wheeler. It’s about a foot longer than a regular bike, with room on the back for accessories ― from a rack and bags to a kayak hauler. Chauffeur a kid, pick up your pizza, or roll home with three potted plants.
