You certainly know how to grab my attention. I recently started riding my ‘commuter’ bike to the gym and the store also and I must say that I find it quite liberating. I paid four bucks for a bike lock, got some lights for riding at night, and carry a backpack for groceries. It’s great for running errands and arguably faster than getting in/out of the car. The NPR article was good, but unfortunately, didn’t account for texting drivers and insane traffic. Portland has long been the most bicycle friendly community in America. I wouldn’t dare put myself or my kids on one of those things around my part of South Carolina. It’s too bad really. Be sure to check out this too: http://davesbikeblog.squarespace.com/
