This is from an article on the "coasting" bikes...
"Sheldon Brown, technical manager at Harris Cyclery, in West Newton, Massachusetts, a self-described Shimano fan who nevertheless calls Coasting "a wrong-headed exercise in form over function." His objection: "Making the bike look simple is not the same as making it be simple. The hubcaps over the wheels cover up the stuff you need to get at to fix a flat tire." He also points out that in hilly terrain, like that of suburban Boston, coaster brakes can be a challenge in stop-and-go traffic."
