Entry level mountain bikes are the perfect bike for people who are looking for one bike to dabble in several different types of riding and who are unwilling to spend more than $600 on their bike. They range in price from about $300 to $600. If you are new to dirt trail biking, or you want to do a combination of dirt and pavement riding, this may be your bike. You can take your entry level mountain bike on the Memorial Park Trails, ride it on the bike paths along the bayous or ride the streets of your neighborhood. They are the Swiss Army Knife of bicycles for people on a budget.Students often use them as campus bikes because they are durable and relatively inexpensive.
