Not so much chock/horror as commiserations - they were bloody dreadful. My brother had one to learn on in a field then on the road. It was hopeless as a field bike and no better on the road. One of the pinnacles of British unreliability. He soon progressed to a cammy Velo that he 'bobbed' & painted day-glo orange, followed by an ex-Met police Triumph Saint with a bent frame and then an only marginally better Bonnie. It's hardly surprising he gave up bikes in favour of cars.
