So I've wanted a mountain bike to take to work to get some exercise, and enjoy the outdoors. I went to walmart today, and decided to buy one, a pretty sweet looking Mongoose 26" bike. I had a Mongoose Californian BMX when I was younger that was a great bike. I was surprised to see the Mongoose name in walmart, as they were pretty top notch a decade or two ago. I figured they were bought out, outsourced, and probably crap nowadays, but I am not a top cyclist, and figured this would be a decent start to see if this were something I liked or not. It came preassembled, so I took it home, and took the tags and such off of it to take it for a quick ride before I left to take it to work to use. My golden retriever pup wanted to come out, so I let him come with me. 5 minutes after I got home with it, I took it down my road for a quick run, and sammy was running along side me. He got out in front of me aways, and somewhat stopped in front of me when I yelled for him to come back. Lance Armstrong, or whatever cyclist pro they have assembling these bikes at wal mart had the rear brake working about 20%, and the front about 250% OF what the rear was. At that point under hard front braking, the front wheel twisted like a pretzel, locking it up, and throwing me head first over the handlebars. I did a complete end-over-end flip in mid air, and landed flat on my back in the middle of the road. While laying there for a second, I saw the bike flipping over top of me, and my dog running for dear life. How I did not get hurt, amazes me...it was a hardcore wipeout, and had to of looked most impressive. I carried the bike back home, and took it to work with me. When I got to work, I took the wheel off, straightened it as good as I could, put tons of slack in the front brake, so it will still turn although the wheel turns nothing close to running true. I got it somewhat rideable, and the next 2 minutes, broke one of the nice plastic pedals. Needless to say, this POS is going back to wally world when I get off of work. Anyone have any suggestions for a decently built bike for reasonable? I don't want to spend more than a couple hundred bucks on something, but need something that will not fall apart or kill me.
