I haven't noticed lone women getting stranded in my area, thank goodness. However, have you ever noticed the fine print on the label on a department store "mountain bike"? Says something to the effect that the bike is only intended for use on smooth pavement and not meant to be jumped, i.e. it only looks like a mountain bike and if you try to use it as if it was a mountain bike, the manufacturer has absolved itself of all responsibility with the fine print that nobody reads. The other day I happened to walk past a beefy-looking "mountain bike" while going into the local jumbo-mart and I glanced down at it and there was an actual hole in the welding that held the fork together. It hadn't been welded properly and would probably fail catastrophically shortly after purchase, especially if somebody didn't read the fine print and took it out on a mountain bike trail!
