This morning my A-bike hit something and I flew face first into the road. Luckily there were no cars or buses behind me or I would have been flattened. However, what I noticed as I scrambled to the pavement was that the bike had refolded itself - ie the central lock had undone itself and the two wheels had come together. It was clearly this, more than the bump in the road that caused my face to be messed up this morning.
Has anyone else experienced this? It makes me hugely reluctant to ride the A-bike again if it is liable to fold like this again when encountering a small obstacle.
