The answer to this question depends greatly on what the beginner wants to do. In many cases, a cross-country or trail mountain bike will offer the best versatility to try new riding styles and terrains. In most cases, these styles are the ones that beginners enjoy more often. However, if you as a beginner want to try your hand at downhill or all mountain styles of riding, there is nothing that says you can’t, and there are mountain bikes in those categories for beginners as well. The trick is to do your research and determine which mountain bike for under $1000 meets your needs the best.
