This range of worthy and plodding postwar utility bikes didn’t have much recommend them in the area of stopping, going, and going around corners. A little dull, the C10 side valve being dullest of all, they provided ride-to-work reliability for the many thousands of people who could afford better than a bicycle. Some spares are hard to find now, and BSA built these bikes to a price affordable by working-class heroes of their day, hence their state of deterioration. They can make a sturdy, low-performance greenlaner.
