Top 10 Best Mountain Bikes Under £300 (July 2021)

In this article we're going to try and find the best mountain bikes under £300. Despite the name, mountain bikes are actually designed to do any kind of biking you want – it's just that manufacturers build them with certain specialities in mind. A mountain bike is a great investment and you don’t want to just pick the cheapest option. If you are seeking a better value then stick to basic designs and materials with standard 26-inch wheels. A basic core design can still measure up to some of the higher priced models in ability and durability.

The Best Mountain Bike Frames

You can't overlook the frame element on a mountain bike under £300. The weight and usability of the MTB very much depend on this. Most of the best entry products are made of aluminium, which is a versatile framing material and comfortable to ride with. In mid-range mountain bike, you may get a mixture of carbon and aluminium. Often the best bikes have carbon with lower components, which is next to an alloy bike. You can go for an alloy bike with mid-range and upgrade the components later. The carbon frame bikes are lighter than the aluminium and tend to be stiffer earlier.

A few years back, carbon bikes had a reputation for being fragile, but the best modern carbon mountain bikes are much stronger and durable. When it comes to looking for the right speed bike, you have a few to choose from. Most standard mountain bikes come in 21-speed, 24-speed and 27-speed. We'd definitely recommend getting a mountain bike with hydraulic disc brakes as v-type brakes aren't so good in wet or muddy conditions.

What Type Of Mountain Bike Should You Get?

Using a mountain bike for city rides and occasional off-roading is a common choice for users. For this kind of use, having dual suspension with dual disc brakes are not a necessity. At the same time is someone is purchasing a mountain bike for serious off-roading activities having the features mentioned here becomes a necessity. This can mean a more expensive bike and will be purely down to your price point.

Hardtail Mountain Bikes Under £300

If you prefer biking on smoother trails, or enjoy taking on large hills to push your cardiovascular endurance. You’ll want to invest in a hardtail mountain bike. These single suspension bikes don’t have the shock absorption of full suspension bikes, but they’re the perfect fit for mountain biking on flatter terrain or shifting up steep slopes.

Full Suspension Mountain Bikes Under £300

Full suspension mountain bikes are must-haves for tackling tough trails, jumps, and obstacles that a hardtail can’t handle. They tend to be pricier than single suspension bikes, but having the full-suspension traction and stability for fearless, affordable mountain biking is a must if you're serious about your off-road adventures.
