The Sportster is a lighter-weight aluminum-framed trike that is designed to be a fast moving trike but still having a seat high enough to get in and out easily.  It sports a 26 inch rear wheel that can develop a higher speed than those that are 20".  Gearing is a 27 speed derailleur system with better quality twist shifters.  Accessories include a rear rack and bag, full set of fenders, and a rear view mirror.
