First off, when you became a member of BikeForums, you agreed to spell out words to the best of your ability- doing that would be much appreciated by the members.
A bike from Walmart is not really going to hold up to too much at all. How old are you and what is your height and weight? Depending on that, you may wish to spend more on a better bike as no one is going to be able to suggest a bike to you at that price.
