I do consider this question a little dumb, BUT, its a question that has always bugged me for years. Alright...so you go into Wal-Mart (other places have this as well) wanting to look for some BMX/stunt bikes. Your on a budget, so your looking for something nice looking and seemingly well built, and cheap. You finally come across a bike that has everything you want. Its got the pegs for doing stunts such as a grinds, and all that nice stuff. So here you are, giving it a nice look over, checking the frame and weld-joints for wear-and-tare. You'll never know. Someone could have brought this bike back after inflicting their own damage to it. Well, after a few minutes of checking the brakes, frame and welds...everything checks out. But then, your eye comes across a white sticker, with black lettering lightly glued to the seat post's tube that's welded onto the bike frame. It reads "This bicycle is not designed for off-road use or stunting." You blink, let a "Hmmmm..." out and take another look at the bike. Its got pegs...the cable de-tangler so the handle bars can rotate a full 360 degrees without the frame getting in the way. All the signs one expects to see of a BMX/stunt bike. But yet, this sticker is there, reading "This bicycle is not designed for off-road use, or stunting."
So here is the question. Why would a bicycle be built to look like it can handle the abuse of jumps and whatnot, when the sticker reads what I quoted above? Could it be for liability purposes?
