There are also 2 speed rear hubs that can be put to use (either kickback or automatic)... same clean lines, no cables and an extra gear .. at 63 and in a moderately hilly area (Marin County) I wanted more than my SS offered ... this bike uses a vintage Sachs 2 speed automatic, is geared 55/75 gear inches and gets a lot of use riding with my buddies on their fully geared road bikes ..
