Twenty... the bulk of them are antiques (like the CCM and Lenton) and a good number are one off hand built bicycles that I have collected over the past 15 or so years but they all get ridden.

The Ron Cooper is a gem of a bicycle and one I would never consider parting with unless I was faced with some dire circumstance or could no longer ride.

My new all rounder / commuter is a 1966 Moulton with a 7 speed IGH which is really ideal... the legs don't always work well enough to ride fixed so a wider gear range is beneficial.
