So odd. I ride my station bike to the station, lock it up and go to work. Come back in the evening in the dark, unlock bike and start riding home. As I pick up speed I notice a loud clanking from the front wheel, then even louder and then the mudguard support comes loose and the clanking is really loud so I stop. Someone had put a padlock around one the spokes of the front wheel and locked it. This had spun round and swung out as I rode, wrecking the front mudguard.
Why? I had to walk home, and now I have to try to get the padlock off without damaging the front wheel (suggestions welcome).
