No I have not and for good reason.

The circle of friends that I run with in my biking circles have all purchased bikes from BD with the same idea that you and many others have of falling for BD marketing fluff (their bikes are nothing like what the crazy marketing mumbo jumbo claims they are) and thinking that they are getting a good or better deal on a bike vs. what people are buying from Trek, Specialized, Giant or another reputable bike manufacturer. Every single one of them has had to deal with cracked frames, failed hubs and a myriad of other issues that you don't have when you spend more money on a good bike from a reputable manufacturer. I'll end this by saying that all of those people I'm referring to no longer are riding Motobecanes and that they all have stated they wished they would have spent more money on a better bike in the first place.
