Welcome to the world modern non-mechanically inclined useless American people. If people would just learn to fix crap themselves they wouldn't need such BS as this. I've been riding for over 40 years and never once have I scratched my head and though, gee wouldn't it be nice to a bicycle roadside service plan. I guess that's what we get today from a generation of grown up infants. If anyone thinks they need this roadside service plan while riding a bike they need to seriously consider a different sport!! Or perhaps just ride indoors on a trainer, and never venture outside.
I ride all the time over 50 miles out from home. I carry tools and other stuff just in case something happens, but I don't fret over not riding far from home because I might have a mechanical problem because I can fix most things that could go wrong, and the things I can't fix rarely if ever break anyways. To those of you scared about that then learn some other basic commom problem type of repairs. A good mini tool and a small folding pair of pliers will fix most things. I wouldn't even be scared about riding a Walmart bike 50 miles out as long as I have my seat bag with me, and most of us have far better bikes than those Walmart jobs which means repairs are far and few between anyways.
And how would a service like that get to a person on some remote mountain trail? Their not going to be able to mostly due to it being impossible to find you, or too much of a hike to get to you; just like to don't come to rescue stuck 4x4's out on some trail. So bend a rim off road your're still walking.
