Interesting chat about wives. My wife was riding bikes even before I met her (I was all of 17 at the time) and rode many bikes over the years with always her A10 in the background. A few years ago her health took a serious turn for the worse and she no longer rides. However, she is adamant that her bikes are maintained and used regularly.
My quandary is that I feel selfish when out for the day on a bike when she can no longer manage to ride and could do with my help around the garden and farm.
I'll be out on her 1913 Douglas tomorrow. Just making sure it's going well, honest.
P.S. The only dynamo chain breakage was on the A10 crossing the Forth Bridge about 1980 or thereabouts and that's because the dynamo commutator flew apart.
