I bought a "Next Extreme" from Wal Mart for $345.00 (after taxes) and was very happy with it... for a while. I had an accident, and took the bike to a pro bike shop, who it turned out couldn't fix it. A special part connecting frame to deraileur was bent. A piece, not 2 inches long, made bike unridable. Went to Wal Mart and was told several times about how it wasn't their responsibility, to which I replied several times, "I know, I'm the one who broke it." I just wanted them to order the part or have their bike mechanic look at it, at MY expense. ( Warranty expired, and wouldn't have applied anyway). After 15 minutes of this I ended up leaving without having gotten anything done. So, I did a search for "Next Extreme Bicycles" etc... and came up with over 63,000 sites on the net, including this BikeForum. Not what I was looking for, but I like it . So, when you by any bike, find out all you can BEFORE you buy. Is it a disposable bike, or can it be repaired?
