Unless something is broken or you are not comfortable with the way your bicycle rides than don't worry about a replacement right away. As you ride more you will gain experience and knowledge riding with others. From what I have seen it is more difficult than usual to find new bicycles currently. I started out on a bicycle not much different than what you have and found that it was a lousy ride on tank trails on the base. The tires wore out to quickly also. So my next purchase was a touring bike. I currently ride a touring bicycle with 2" wide tires. Being the hot season I do most of my riding at night or early morning. Its 110 degrees right now.
