I love the standard B17, but am getting a Flyer for my wife's shopping bike. The shopping bike is a new Panasonic, an electric-assisted model, but which is designed for Japanese people in mind. The seat tube is too short, and the original seat too soft. When I ride the bike, I can simply swap the new seat on a longer seat tube. The reason I want the Flyer is because of the upright seating position, which tends to send the bumps and shocks up the seat. The springs on the Flyer should soak up some of the bumps.
