As Col said, it could have been mistaken identity. But then again, knowing the area and some of the trogolodytes that live around here, I wouldn't rule out them just deciding to have a little 'fun' and picking on a cyclist.
Not unknown for people round here to just pick a stranger at random and beat the living daylights out of them. Just for a laugh, likesay; ken ?
