These are from a list of broken frames; there are many more listed at the page above, but most do not have photos.
In most cases, usage history is not given, and in some cases there is no description at all — some failures may have been caused by putting the bike on a roof rack then driving in to a garage. Others are far more likely to have come from regular vigorous riding.
