Full Suspension Mountain Bike Buyers Guide

Twist gears vs. levers

Gears are exceptionally important in mountain biking, as changing terrain and slopes requires different gear settings. The added control of a wide range of gears can prove important on rough, difficult terrain. Most bikes offer gear levers attached to the handlebars, but some allow you to change gears through twisting the handlebars.

The twist gear system is smoother and easier to use at speed, giving a little more control and fluidity to the gear change experience. This slightly more fluid control can improve the cycling experience when traveling faster, making more of a difference for more dedicated cyclists.

Disc brakes

Disc brakes enable your bike to stop faster, giving more control and a more comfortable braking experience. This is because they offer a larger pad than alternatives, providing a larger contact area against the wheels for faster braking action. In addition to this, disc brakes tend to last a little longer before requiring replacement, reducing the level of maintenance needed to keep your mountain bike in good working order.

Tire sizes

Different mountain bikes come with varying sizes of wheel, and this can substantially affect the experience of riding the bike. Larger wheels mask the roughness of the terrain, making uncomfortable bumps seem smaller and easier to ride over comfortably and smoothly, while smaller wheels allow you to feel the full range of textures beneath your wheels as you ride.

Larger wheels may seem like the obvious choice for comfort, but smaller wheels have their advantages too; that added ability to feel the ground beneath you gives more control, helping you to feel properly in tune with the ground below you and to adjust to fit changing surfaces more rapidly and fluidly.

Alloy wheels

The wheels of your bike take more strain than any other component during a bike ride. This can lead to damage through extensive use, and so sturdier wheels can be a valuable feature in any mountain bike. Damage to your wheels can push them out of shape, reducing control over your movement and potentially causing problems with your ride. Alloy wheels are designed for strength and resilience, reducing the chance of such damage and keeping your bike as easy to control as possible even through heavy use on rough, hard ground.

Why full suspension?

Hardtail bikes offer suspension at the front but not the rear wheel, while full suspension bikes have suspension systems built into both the front fork and the rear wheel mount. This gives greater impact absorbency, reducing the shock of riding over rough terrain. Hardtail bikes can be lighter, as suspension systems add to the weight of any bike, but offer few mechanical advantages. As such, unless the weight of your bike is the primary concern, full suspension options are likely to be the better choice.


There are a huge number of full suspension mountain bikes on the market in 2020, as well as a similarly wide range of hardtail bikes, but the 5 listed above are some of the very best.

All of these offer powerful suspension and good control while being relatively light and durable. The question of which trail bike is right for you will depend on which features you prioritize for your personal needs; some of these bikes focus on comfort, while others focus on precision control, smooth gear shifts, or fast braking. Your decision should focus on your personal plans for your mountain bike.

Consider whether you intend to use it for rougher, more extreme terrain or more casual off-road cycling, as well as your expected speed or intensity of bike rides. All of the bikes above are worth considering, and hopefully, this guide will help you to buy with confidence, knowing that whichever you choose will be a good bike for you.
