Top 10 Best Affordable Mountain Bikes 2018

mountain bikes for sale, cheap mountain bikes, best mountain bikes under 500, best affordable mountain bikes



Whether your budget is under $1,000 or less than $300, it’s possible to find an affordable mountain bike for your lifestyle and riding demands. Aside from price and brand, one of the top considerations when looking for a mountain bike is whether to choose a hardtail or full suspension bike.

Unlike full suspension mountain bikes, hardtails are mechanically simpler as they don’t have pivots or rear shocks. Hardtails generally don’t wear out as fast as full suspension bikes, and they are typically cheaper as there aren’t as many parts. Hardtail mountain bikes tend to be lighter and fun to ride on the trails. Full suspension mountain bikes have many positive features, including better handling thanks to their rear suspension and enhanced absorption on trails.

Wheel size is also important. Some of the most popular wheel sizes include 26 and 29 inches, although you may also see bikes with 27.5-inch wheels. The 26-inch tires have long been the most popular on mountain bikes due to their overall stability and agility. It’s also easier to find replacements when you need them. The 29-inch tire is becoming increasingly prominent for its increased stability and control, especially on rougher terrain, along with sustained momentum once the bike is moving. However, because this tire is a bit larger, some riders find it tougher to maneuver the bike in tighter spaces or when it’s time to make a sharp turn. If you’re looking for a tire that can roll over obstacles as effortlessly as the 29-inch but don’t want to compromise maneuverability, consider a bike with 27.5-inch wheels.

Factors such as riding style, the type of terrain you typically ride, personal preference, and budget can also help determine which mountain bike is best for you. Amazon’s bike buying guide can help you locate the best size and type of bike for your budget.
