I owned a walmart bike when i was a freshman in college. The first week the pedal fell off. I tried to put it back, but the threads got damaged on the pedal (I was lucky it was not the crank-arm). Also, it was nearly impossible to tune the gears. The shifting was lousy. If walmart bikes were worth repairing, they would have done so in their store to make a few more $.

One thing I have to admit, the steel frame and fork seemed decent on the Murray MTB. Only beef, the parts were nearly impossible to find, and i am not even sure the standard parts will fit these frames. Anyhoo...i never regret buying the walmart bike for $80. It worked fine for about a year and cost me next to nothing (good thing it got stolen). I am planning to purchase another walmart bike and will review it thoroughly. [Rumor has it, these bikes dont last more than 100 miles, and i don't disbelieve it, but i want to put the myth to the test. Expect a new thread soon.]

This is not my video, but this rider seems very content with his $75 bike.
