Our buying guide aims to run you through all the necessary things you need to know in order to make an informed choice.

Type Of Suspension

Mountain bikes are tailored for specific riding styles and terrains. For instance, certain types are fitted with large rear and front suspension bike to handle rough trails and big drops. Other models feature so suspension to make them lighter and faster on smooth trails.

Yet others feature limited suspensions in order to achieve a balance between support and speed. Based on this information, you will have chosen between dual/full suspension, hardtail and rigid. Find out what each of these types means.

Wheel Size

Wheels are extremely important considering the terrains you wish to cover with your mountain bike. In many cases, you will find mountain bike wheels made of aluminum and come in different sizes from 26 inches to as high as 29 inches.

The 26-inch wheels are lightweight and offer the greatest stiffness. In terms of ride, they accelerate quite quickly and their relatively smaller rotational mass can tear through twisty one-track at high speeds.

The 29-inch wheels (29er) are the largest. They feel slower to accelerate to optimal speed and the larger rim, as well as longer spokes, increase its weight. The large size is great because it offers more traction and is more adept when it comes to handling bumpy grounds.

The 27.5-inch wheels are half-way in size between 26-inch wheels and 29-inch wheels and therefore feature a ride intermediate between the two sizes.

Frame Material

The frame material of a mountain bike has a direct influence on the bikes strength, weight, longevity, ride quality and price. Aluminum alloy is the preferred material for the purpose of the frame because it is light in weight and extremely durable.

Other frames include stainless steel (tough, inexpensive but heavy), titanium (strong, light but extremely expensive) and carbon fiber (strong, lightweight but expensive).

Gears

The number of gears a bike has is the product of its front chain rings multiplied by the number of sockets on the cassette. Mountain bike gears range from single-speed to as much as 30 gears. Choose gears depending on the terrain where you will be riding and your fitness level.

In case your ridings will mostly be on steep hills and challenging climbs, then you’d better opt for more gears. Beginners can do well with single chaining because they are lighter and simpler to ride.

Brakes

You can choose between mountain bikes based on the type of brakes they are fitted with. Today, disc brakes have replaced rim bikes in all mountain bikes except the entry-level bikes. Disc brakes offer more consistent performance in wet and steep terrains; they are cheaper to replace and causes less finger strain.

However, they can be expensive and difficult to inspect. Rim brakes, on the other hand, are more economical but they are less durable and not gentle on your fingers.

Size And Fit

You will find it easier and more enjoyable to ride a bike that fits well and is right for your flexibility, height and riding style. A mountain bike that fits you properly will improve your handling as well as confidence on the road to enable you to tackle more technical and challenging rides.

Mountain bikes come is standard sizes S, M and L that you choose from depending on your own height, riding style, and weight.
