What To Look For
Purchasing a mountain bike is a detailed process. The first step is to determine which type of mountain bike you want. Mountain bikes come in a variety of styles, including cross country, race/performance, downhill/free ride and all-mountain. Each type of mountain bike features geometry and components designed specifically for different styles of riding. For instance, downhill bikes feature heavy frames, large amounts of rear and front suspension and limited gear selection--qualities that make them well-suited for fast, shuttle-based biking and jumps. Cross-country bikes, on the other hand, are lightweight, with a full set of gears and have lesser travel forks and rear shocks. Decide what your own riding style is, what type of terrain (cross-country trails, lift-served downhill, bike parks, etc.) you plan to ride and then home in on a category. At the same time, decide if you want a rigid, hard tail or full-suspension bike. Downhill and free-ride styles demand full-suspension, but in cross country it depends on the ruggedness of the trails you ride. Finally, begin to closely compare bikes within your price range. Read reviews on websites like MTBR.com and compare components and frame geometry among various models to find one that suits you. Always fit your mountain bike to your body and test ride it for comfort.
Common Pitfalls
How a bike looks should be the last factor you consider. It's much better to get a bike that suits your riding style and budget. Also, don't spend money on features you don't need. For instance, if you're a cross-country rider, you don't need a bike that has 8 inches of suspension.
Where To Buy
Buy your bike in person at a local bike shop. Some online retailers, like REI, allow you to order online, but require in-store pickup. Buying your bike in person is the only way to fully test it out. If you're looking for a particular brand, visit the company website to find an authorized dealer in your area.
Cost
Mountain bikes vary widely in price. Recreational bikes can be found for as little as $200 or $300. In general, bikes on the lower end of the price scale aren't designed for aggressive trail riding. High-end mountain bikes can cost $10,000 and more. Basically, the more expensive the bike, the lighter it is, the better components it has and the better it will perform. Suspension also impacts price, with full-suspension bikes the most expensive and hard tails more expensive than rigid bikes.
Accessories
Accessories you should consider are a helmet, water bottle cage and/or hydration pack, a tire repair kit, a chain tool, mountain bike gloves and sunglasses. Also decide if there's anything you'd like to replace, such as the saddle or pedals. Also ask about the warranty and what is covered.
