General Cycling Discussion - I need help finding a new bike

Hi I wanted to know which of these bikes will be the best. I ride every day for about 3 hours and need a bike that can go fast and is realiable.

I know these bikes are cheap because im young and have been saving up my money.

Those bikes are really junk. They MIGHT work for awhile to ride a mile or two, but they won't last and you'll never be happy with them. And when they break, Walmart won't be able to fix them, or even try--you'll have to go to a bike shop, where any kind of repair will cost you more than the original cost of the bike.
If I were you, I'd go to a real bike shop and tell them what you're looking for. They should be able to recommend something at a reasonable price (I checked with a friend of mine who owns a bike shop here, and he said he could get you something decent for about $300-$400). I know it's hard, but you'll be better off doing that.
Another option would be to buy something used, from a bike shop if you can or maybe from a thrift shop like Salvation Army or Good Will. Around here, those stores sometimes have really nice used bikes from about $25-$75. The problem with that is that you have to inspect the bike yourself to see if it's in good condition, and that's hard for a beginner. If you have a friend who rides a lot, you might ask him or her to go with you. But I'd really stay away from those cheap Walmart bikes.

What are you riding right now? I would find it hard to believe that those bikes would be able to take 3 hours of riding everyday for a very long time. I would never want to subject myself to 3 hours of riding a 40 pound bike either.

You really get what you pay for. Please keep saving your money for something that will last for a while and provide more riding enjoyment.

Just an idea....

If you find new to be expensive, keep your eye out on Craigslist. You can find a name brand bike for 1/2 or more less than MSRP.

With those Walmart bikes, you would seriously do better to find a used mountain bike on Craigslist (http://www.craigslist.org).

Look for the names that bike stores sell, like Specialized, Trek, Giant etc.

How can a full suspension bike be under $100 is beyond me.

Please don't let it go down again, LBS is your friend, stop this Wallyworld action,we will help you to find a good bike no matter what,please give us a chance,dang it.

If you want to buy a bike from Wal-Mart you will probably need to be able to set it up and adjust it yourself.

Took a look at the Wal-Mart website, since I had to see these "bargain priced" bikes for myself, the following actually looked worth considering:

$132 Mongoose Paver Commuter bike with rear rack:

$139 Kent GMC Denali Road Bike:

$229 Schwinn Varsity Road Bike:

$189 Schwinn Link Comfort Bike:

$129 Schwinn Delmar Cruiser:

The GMC Denali Road Bike I included only because it is a $139 road bike. The Mongoose Commuter might be a better bet.
