Biomega is one of the most innovative company when it comes to city bikes. Their Copenhagen model is a stunting exemple of that. The shaft of the drivetrain is enclosed in the chainstay, to reduce weight (although the bike is over 30 pounds). People that makes shaft drive and that don't use this route are either lazy or to much price oriented. The bike even have an internal geared hub, which is not that common for shaft bike.
