Best mountain bike in 2024 | Find the right MTB for your riding and budget

Our in-depth buyer's guide to getting the right mountain bike for you

Choosing the best mountain bike for your riding is vital if you want to get maximum enjoyment out on the trails – but finding the right bike in a crowded market can be a minefield.

Fear not, because our ultimate guide to buying a mountain bike will run you through all you need to know, from choosing the best machine for your budget to matching a bike to your riding style.

Our tech writers have tested hundreds of mountain bikes over the years, ranging from budget hardtails to the most extreme downhill bikes on the market.

Mountain bike design is one of the fastest-evolving areas in the industry, with bikes looking barely recognisable from those made 20 or more years ago, and frame designers free to experiment, unlike rigid UCI-regulated road bikes.

Recently, there’s been a huge surge in electric mountain bikes, with the addition of battery-powered electric bike motors bringing new elements to the sport.

At the middle and top of the market, it's not uncommon to see full-suspension carbon fibre frames and electronic gearing, while the bottom usually features hardtail metal frames matched to a suspension fork. But, whatever their price, mountain bikes are designed to get you out on the trails and experience the joy of whizzing through the trees.

Because mountain biking is so multi-faceted, we have split this list into discipline categories and provided our entry-level top picks, so there should be something for everyone. You can skip to these categories using the links below:

We’ve also included our in-depth mountain bike buyer's guide, which details everything you need to know about mountain bikes so you can find the right bike for you.

Best mountain bikes 2024

Best trail mountain bikes

The best trail bikes balance the trail-conquering characteristics of an enduro bike with the pedalling efficiency of a cross-country bike. They're incredibly popular for their wide-ranging ability.

Bird Aether 9

Pack shot of the Bird Aether 9 full suspension mountain bike
The Bird Aether 9 is pleasingly simple and covers miles with ease. - Russell Burton / Immediate Media
  • £3,850 as tested
  • Pros: BikeRadar's trail bike of the year 2021; excellent geometry; exceptional value for money
  • Cons: Smoother bikes available

The Bird Aether 9 delivers in virtually all situations, from long days in the saddle to short, sharp bursts in the woods.

Bird is known for long and slack geometry, and the Aether 9 follows suit.

With a 65-degree head-tube angle and a RockShox 140mm Pike Ultimate fork and Super Deluxe rear shock, the bike feels super-stable and right at home on twisty, steep descents.

When it comes to climbing, a good reach and steep 77-degree seat tube angle put your body weight in the right place.

Cannondale Habit 4

Cannondale Habit 4 full suspension mountain bike
Cannondale's updated Habit covers distance well and remains playful on the descents.
  • £2,300 / $2,300 / €2,699 / AU$4,399 as tested
  • Pros: Well-balanced; confidence-inspiring ride; fun and flicky
  • Cons: Shimano Deore drivetrain can be a little clunky

The Habit 4 impressed us with its playful and balanced ride that is sure-footed and quick to turn when pointed downhill.

Its aluminium frame features size-specific geometry, with the chainstay length increasing through the size range.

The RockShox Recon fork tended to bind on hard compressions, but this didn't take much away from the bike's overall performance and highlights how competent the frame is.

Its steep seat tube angle of 77.5 degrees makes climbing comfortable, though it's not the most efficient we've tested.

Merida One-Forty 700

Merida One-Forty 700
Olly Bowman / Our Media
  • £3,100 / €3,869 as tested
  • Pros: Boundary-pushing geometry options; one of the best climbers out there
  • Cons: Stem could be shorter; not the smoothest ride

The Merida One-Forty 700 was our Trail Bike of the Year 2023, impressing us with its well-considered geometry and value for money.

It shares its carbon fibre frame with the longer-travel One-Sixty, uses flex stays in the rear linkage and provides 140mm of rear travel.

While it's not the smoothest on janky descents, on the climbs, the bike has zero wallow and a perky attitude that rewards efforts with efficiency.

The 150mm Marzocchi Z1 fork and RockShox Deluxe Select rear shock worked very well, and the geometry is spot-on for downhill, with composed and accurate handling.

Norco Fluid FS C2

The Fluid is quick up the hills and capable on the descents. - Steve Behr / Our Media
  • £4,999 / $4,999 / €5,299 as tested
  • Pros: Confidence-inspiring geometry; makes good use of suspension travel
  • Cons: Brakes could be more powerful; tyres won't suit everyone

Norco's Fluid FS C2 has great agility on the trail, while remaining calm and collected at high speeds.

The bike feels planted through rough terrain, with its 140mm RockShox Pike Select fork and Super Deluxe Select shock taking care of trail imperfections without feeling wallowy.

On the hills, it impresses, with an eager efficiency that makes you want to race up every slope.

We felt the SRAM G2 RS brakes were a little underpowered in some situations, with the bike suiting beefier stoppers.

Best cross-country mountain bikes

The best cross-country mountain bikes often feature svelte, lightweight frames with 100 to 120mm of travel for racing up hills and flying down descents. In recent years, bikes have become more aggressive to cope with ever-more challenging XC courses.

Trek Supercaliber SLR 9.9 XX AXS Gen 2

Trek Supercaliber SLR 9.9 vs Specialized S-Works Epic World Cup - 02
The Trek Supercaliber promises the efficiency of a hardtail. - Andy Lloyd / Our Media
  • £10,800 as tested
  • Pros: Direct feel with capable geometry
  • Cons: One-piece bar and stem, plus narrow tyres

The Supercaliber SLR 9.9 XX AXS Gen 2 is race-bred, and delivers sharp handling and efficient power transfer. 

The IsoStrut rear shock, partially hidden in the top tube, offers the efficiency of a hardtail with the comfort of rear suspension.

A well-balanced and capable geometry makes the bike feel confident going downhill, but it really shines on the ups where its ground-covering ability is highlighted.

In pursuit of speed, Trek has given the Supercaliber skinny 2.2in tyres that don't quite cut the mustard for regular trail riding.

YT Izzo Uncaged 7

YT Izzo Uncaged 7
The Izzo rockets up the hills and feels composed on descents. - Andy Lloyd / OurMedia
  • £6,299 / $6,499 as tested
  • Pros: A riot of a descender that still climbs like the best of them; value for money
  • Cons: Direct sales might not appeal to all

The YT’s balanced 120mm of suspension and geometry make it a missile on the descents, with handling and bump absorption you'd expect from a trail bike.

The geometry is very progressive, with a 66.5-degree head angle and 77.5-degree effective seat tube angle that centre you over the cranks for impressive pedalling efficiency.

YT has given the bike a mouth-watering spec, equipping the Izzo with a top-of-the-line RockShox SID Ultimate fork and a SIDLuxe Ultimate rear shock, as well as SRAM's wireless XX1 AXS drivetrain.

While it has more travel than most XC bikes, the Izzo still climbs with ease, with the platform remaining supportive when pedalling.

Cannondale Scalpel HT Carbon 4

Cannondale Scalpel HT Carbon 4
Finlay Anderson / Our Media
  • £2,600 / $2,300 as tested
  • Pros: Impressive all-round capability; good spec for the price tag
  • Cons: Seat tube bottle boss position limits post-insertion depth

The Scalpel HT Carbon 4 is the entry point to Cannondale's Scalpel line-up, and is aimed toward the trail end of the cross-country segment.

Slacker head angles give the Scalpel HT enduro-esque handling characteristics, while steep seat tube angles aid climbing ability.

Flex in the rear triangle aids in finding traction uphill, and smooths out trail imperfections on the way down.

The RockShox SID SL fork gives good support up front, dealing with the majority of trails well.

Best enduro mountain bikes

The best enduro mountain bikes will have long suspension travel and will be able to compete with downhill bikes on technical descents, while enabling you to ride back up to the top of the hill.

Norco Shore 2

Norco Shore 2 freeride mountain bike
The Shore 2 is one of the best-handling bikes and won't break the bank. - Ian Linton / Immediate Media
  • Price: £3,399 / $5,199 as tested
  • Pros: Dialled geometry; fast handling
  • Cons: Weight might be a problem for some

While it is on the heavy side, the Shore is one of the best-riding, long-travel mountain bikes on the market.

Offering 180mm of rear-wheel travel, the Shore is a high-pivot enduro mountain bike with a Horst-link suspension design, which provides confidence-inspiring levels of bump-absorption.

Norco has given the bike a progressive geometry with a spacious 480mm reach, 63-degree head tube angle and 445mm chainstays on our size large.

Despite its weight, the Shore winches up hills well and its saddle makes for a comfortable place to spend a day.

Canyon Strive CFR

Canyon Strive enduro mountain bike
The Canyon Strive offers serious potential in the right hands, but isn't the most comfortable when cruising. - Andy Lloyd / Our Media
  • Price: £5,999 / $7,299 / €6,299 as tested
  • Pros: Chassis provides stability at high speeds; race bike feel with high-performance potential
  • Cons: Suspension can feel harsh at low speeds

The Strive CFR is Canyon's enduro race bike, rolling on 29in wheels and offering 170mm of suspension travel.

Being direct to the consumer, the Strive CFR is well-specced compared to its competition, with Kashima-coated Fox suspension, Shimano XTR drivetrain and brakes paired with a Race Face Next RS crankset.

The Shapeshifter system allows for better on-the-fly adjustment of the bike's geometry and presents a marked improvement on the previous model.

High speeds are rewarded with impressive suspension kinematics, but when cruising at lower speed, the frame can feel rather harsh.

Cotic RocketMAX Gen4 Mullet Silver

Cotic RocketMAX Gen4 Mullet Silver full suspension mountain bike
The RocketMAX Gen4 is a steel outlier in a market dominated by aluminium and carbon fibre. - Andy Lloyd / Our Media
  • Price: £4,949 as tested
  • Pros: Stable and confident through turns; carries speed well
  • Cons: Not as forgiving as other bikes

Cotic's RocketMAX carries speed well when pointed downhill, and handles rough corners with ease –without feeling over-gunned.

The bike's composure is faultless, though our test bike generated quite a lot of noise on bumpy descents.

Cotic offers a host of customisable spec, with our test bike featuring a RockShox ZEB Ultimate fork and a Cane Creek Double Barrel Kitsuma coil shock.

It's not the best climber, but it doesn't feel as though it's needlessly rinsing your energy.

Best electric mountain bikes

The best electric mountain bikes make climbs disappear before disguising their weight on the way back down. 'Full-fat' and 'SL' bikes divide the discipline, with the latter usually having a smaller battery and motor to reduce weight.

Focus JAM2 SL 9.9

Focus Jam2 SL 9.9 full suspension mountain eBike - eMTB
The JAM2 has a wide performance envelope. - Ian Linton / Our Media
  • £7,499 / €8,499 / AU$14,499 as tested
  • Pros: Impeccable performance; powerful and frugal motor
  • Cons: Stock tyres are inadequate; Fazua ring controller feels cheap

The Focus JAM2 SL 9.9 is a lightweight electric mountain bike that uses Fazua's Ride 60 motor, which provides it with 60Nm of torque connected to a 430Wh battery.

Flip chips in the linkage enable you to set the bike up longer, lower and slacker should you wish to make it more aggressive, which helps it span the trail and enduro categories.

The JAM2 SL 9.9 is seriously fun on a variety of trails, and the motor is seemingly frugal, with power consumption lasting for many laps.

The only letdown from the spec was the lightweight tyres, though this is easily corrected.

Orbea Wild M-Team

Orbea Wild M-Team eMTB
Olly Bowman / Our Media
  • £9,207 as tested
  • Capable and supple suspension
  • Bosch motor and battery

Orbea's Wild M-Team remains balanced when ascending or descending, with the suspension reliably gobbling up rough ground and maintaining grip through technical sections.

The Wild M-Team is powered by a Bosch Performance Line CX motor with a PowerTube 750Wh battery, which gives it 85Nm of torque and an impressive range.

Its strong chassis is mated to a decent spec that features a Shimano XT drivetrain and brakes, with a 170mm Fox 38 Factory fork and an X2 Factory shock controlling 160mm of rear-wheel travel.

Specialized S-Works Turbo Levo SL II

Specialized S-Works Turbo Levo SL II lightweight full suspension electric mountain bike
The S-Works Turbo Levo SL II is near-perfect. - Ian Linton / Our Media
  • £13,000 as tested
  • Pros: Incredibly wide performance band; adaptable geometry
  • Cons: Inadequate rear tyre casing; cost

Specialized's latest S-Works Turbo Levo SL uses the 'semi-skimmed' Turbo SL 1.2 motor, which pumps out 50Nm of torque and 320W of power.

The bike feels at home on all types of terrain, from shallow gradient flow lines to steep, rough tech.

Adjustable geometry enables you to run the bike with a 'mullet' setup, with the smaller wheel adding extra agility.

A high-end spec list featuring Fox Factory suspension and SRAM's XX Eagle Transmission, makes the bike a masterpiece at pace, though this comes at a cost.

Best hardtail mountain bikes

The best hardtail mountain bikes will provide excellent efficiency without transferring every bump on the trail through the pedals.

Lapierre Prorace CF 9.9

Lapierre Prorace CF 9.9 hardtail mountain bike
This is Lapierre's XC-focused hardtail, the ProRace. - Russell Burton / Our Media
  • £5,999 / €6,799 as tested
  • Pros: Good value for the money; great all-round capability
  • Cons: Press-fit bottom bracket may be a pain for home mechanics

The Lapierre Prorace CF 9.9 is designed for cross-country racing and uses a carbon fibre frame with in-built compliance.

A triple-triangle design is used to give lateral flex to the bike's rear end, which adds traction on technical climbs and damps trail noise well.

The geometry makes the bike agile and engaging on the trail, with the Prorace inspiring confidence on descents thanks to calm and predictable handling.

While it's pricey, SRAM's X01 AXS groupset, the RockShox SID SL Ultimate fork and Lapierre's own XC SL carbon wheelset make up a decent spec for the money.

Specialized Rockhopper Elite 29

Specialized Rockhopper Elite 29 hardtail mountain bike
The Specialized Rockhopper Elite 29 covers the ground at speed. - Ian Linton / Our Media
  • £949 / $1,150 / €975 / AU$1,300 as tested
  • Pros: Fast-rolling and quick up the hills; lightweight and well specced
  • Cons: Short fork travel is limiting

The Rockhopper Elite 29 has a solid spec choice that makes it fun on not so technical trails

29in wheels help roll over the majority of trail imperfections and the RockShox Judy Solo Air fork provides good support on the descents.

Its short travel, which ranges from 80mm to 100mm depending on size, makes for an engaging ride, though it requires some skill to navigate technical sections of trail.

Best downhill mountain bikes

The best downhill bikes will eat up the lumpiest terrain on offer, with the longest travel of any discipline and geometry that is focused solely on descending.

Giant Glory Advanced

Pack shot of the Giant Glory Advanced full suspension mountain bike
Giant Glory Advanced. - Tom Hardman
  • £7,499 / $8,000 / €7,999 / AU$11,499 as tested
  • Pros: Plush travel with plenty of support; high levels of adjustability; great shock tune
  • Cons: Rims dent easily; high-speed rebound adjuster difficult to reach

Giant's Glory lives up to its legacy, with a capable and sturdy ride feel that eggs you on down the choppiest of descents.

This Glory Advanced comes with a 203mm Fox Factory 40 fork up front and a DHX2 Factory shock controlling 200mm of travel, which soaks up big hits well.

Adjustable geometry in the frame enables you to experiment with different setups to dial in the bike.

The Giant AM30 rims are the Achilles heel of this bike and were quick to dent through rough terrain.

Giant's Glory performs well when faced with a variety of trails and conditions, maintaining its composure throughout.

Propain Rage 3 CF Mix Highend

Pack shot of the Propain Rage 3 CF Mix Highend full suspension mountain bike
The Rage 3 CF Mix Highend runs on a mixed 'mullet' wheel size. - Tom Hardman
  • £6,519 / €6,389 as tested
  • Pros: Handles steep tech and jumps with ease; 215mm of travel is very forgiving; pedals better than expected
  • Cons: Seat tube could be shorter; saddle a little chunky for our tester's preference

The Rage 3 offers top-end performance at a reasonable price, with a 200mm Fox 40 Factory fork featuring up-front and a Float DHX2 Factory shock mounted in the frame.

The bike has a playful character and provides high levels of performance whatever the gradient, with the 215mm of rear-wheel travel sucking up big hits and remaining supportive down the trail.

On the roughest terrain, the bike lacks the same composure as other bikes we've tested.

Nukeproof Dissent 297 RS

Pack shot of the Nukeproof Dissent Carbon 297 RS full suspension mountain bike
Nukeproof's Dissent Carbon 297 RS is priced attractively. - Tom Hardman
  • £6,000 as tested
  • Pros: Competitive price compared to rivals; good beginning and end-stroke feel
  • Cons: Low stack height; feels bogged down at slower speeds

Nukeproof's Dissent Carbon 297 RS proves to be a great platform for aggressive riders, thanks to its calm and collected nature.

This leads to it feeling a little sluggish on lesser gradients and at slower speeds.

Its carbon fibre frame produces 200mm of travel through Nukeproof's Fallout linkage, and this is controlled by a RockShox Super Deluxe Ultimate shock.

On the front, there's a 200mm RockShox Boxxer Ultimate suspension fork, which provides plenty of support and direct steering.

Best budget mountain bikes

The best budget mountain bikes will get you out on the trails without breaking the bank, and offer a solid platform for you to develop your skills on.

Voodoo Bizango Pro

Voodoo Bizango Pro
Ian Linton / Our Media
  • £950 / $1,258 as tested
  • Pros: High-quality spec for the price; upgrade potential
  • Cons: High stack height

The Bizango Pro offers a high performance level at a very reasonable price.

A proper trail spec features, with a RockShox FS-35 Gold 130mm fork, 12-speed Shimano Deore and Maxxis tyres helping to get the most out of the frame.

The bike is very confidence-inspiring, feeling stable downhill and especially so when railing turns.

This led us to push the bike further than trail-centre blues and reds, and into more technically rated trails.

Tolerances between the seat tube and seatpost are quite large, which leads to the saddle dropping on occasion, though this was solved by the application of some carbon assembly paste.

Calibre Rake 29

Calibre Rake 29 pack shot
Andy Lloyd / Our Media
  • £700 (£550 with GO Outdoors membership card) as tested
  • Pros: Impressive value for money; playful handling
  • Cons: Lack of thru-axles limits wheel upgrades

The Calibre Rake 29 offers great value for money, featuring spec that wouldn't be out of place on bikes twice the price.

A 100mm RockShox FS-Judy TK takes the vibrations out of rough trails, although there's some flex in the fork on hard compressions, making steering a little inaccurate when pushed hard.

The Clarks M2 hydraulic disc brakes give confident stopping power that enables you to tackle trail-centre descents with speed.

While the frame was quite stiff, the WTB Trail Boss tyres provided plenty of comfort and gave enough grip to comfortably push the bike.

Carrera Titan X

Pack shot of the Carrera Titan X full-suspension mountain bike
The Titan X is one of the cheapest trail-rated full-suspension bikes around. - Steve Behr / Immediate Media
  • £850 as tested
  • Pros: Better equipped than virtually anything else at this price; rear suspension is good for the money
  • Cons: Three-size range doesn’t work for taller riders

The Titan X offers serious value for money, with full-suspension and a SRAM SX 12-speed drivetrain.

Its geometry might not be as progressive as pricier options, but it's by no means a throwback and it impresses on both climbs and descents.

The dropper post offers big performance gains too, and while the handling over technical terrain isn't the best, there's no getting past how good the kit is on this bike for the price.

Our only major concern is that the three-size range will limit smaller and taller riders.

How we test mountain bikes

We’ve been testing mountain bikes for well over a decade, and have tracked major developments in mountain bike tech, from the widespread adoption of the dropper post through to electronic suspension.

We’ve tested all the major mountain bikes since our inception in 2007, from cross-country bikes to downhill bikes and budget rides to pro-level superbikes.

Working with our colleagues at MBUK magazine, our bike reviews are always editorially independent – with no exceptions. Our reviewers comprehensively test each bike, always reflecting on performance, value and the wider market when delivering their verdict.

Buyer's guide to mountain bikes

Making sure you have the right mountain bike for the riding you want to do is important. - Andy Lloyd / Our Media

Choosing a new mountain bike to buy can be daunting. The sheer variety of mountain bike types, not to mention the bewildering array of technology and terminology, may feel overwhelming.

Technology evolves every year, new mountain bike standards emerge and old ones swiftly become outdated. An ever-growing dictionary of jargon means the mountain bike market can be a confusing place, even for seasoned riders.

Highly specialised bikes sit side-by-side with machines that claim to excel at everything. And they’re all spread over such a vast price range that it can be hard to know where to start.

This guide sets out all the factors you should consider when looking for a new ride.

Where do you want to ride?

It can sometimes be easy to overestimate the type of riding you want to do. - Scott Windsor / Our Media

It’s important to establish early on what sort of trails you intend to ride and on what terrain you want your bike to excel.

This will help you decide what category of bike you need, from short-travel, lightweight cross-country rigs to robust, chunky downhill race bikes.

The different types of mountain bike

There are four main categories of mountain bikes, with each having its own intended discipline.

Cross-country bikes

Tom Marvin riding Specialized Epic World Cup
Cross-country bikes are becoming increasingly capable. - Andy Lloyd / Our Media

Cross-country bikes usually feature 60-120mm of suspension travel and are designed for smooth and fast-flowing trails, as well as competing on the race circuit.

These bikes tend to feature svelte framesets that reduce weight, making them excel at climbing and rapid acceleration.

Downcountry has emerged as a subdiscipline that sits at the more aggressive end of cross-country, with downcountry bikes featuring beefier components to tackle heavier trail use.

Trail bikes

Trail bikes are good all-rounders, with some able to hold their own in chunky, enduro terrain. - Steve Behr / Our Media

Trail bikes are what the majority of people ride, with suspension travel ranging from 120-160mm.

These bikes are designed to get you up to the top of a trail with relative efficiency, while providing good capability on the way back down.

They aren't quite as hard-hitting as enduro bikes, but this trade-off is often made in the interest of weight savings.

Enduro bikes

Enduro bikes provide good rideability, while offering great descending characteristics. - Ian Linton / Our Media

Enduro bikes provide downhill bike capability, while enabling you to winch yourself to the top of the trail.

With travel that can range from 160mm to 190mm, these bikes eat up descents, providing plenty of gravity-fuelled fun.

Due to their added strength and capability, they aren't as efficient as trail bikes, though low gearing should get you up the same climbs.

Downhill bikes

Downhill bikes are designed around one thing – descending. - Tom Hardman

Downhill bikes are focused solely on descending, with travel that is usually 200mm or more.

These bikes are often used at bike parks because their gearing means it's near-impossible to ride back to the top of the trail, making a chairlift or ca lift necessary.

Thanks to their speciality, there is no comprise in the geometry for climbing ability, making them the fastest and most stable bikes to descend on.

What to look for in a mountain bike

Suspension

Canyon Lux World Cup CFR Team full suspension mountain bike
Cross-country bikes will usually feature shorter-travel suspension. - Andy Lloyd / OurMedia

Less suspension travel usually means a lighter, faster bike uphill.

More travel equals better downhill capability. If you’re new to the sport and want to try a bit of everything, a mid-travel trail bike is the best all-rounder.

Coil suspension requires less servicing than air, with only the damper needing maintenance. - Andy Lloyd / Our Media

Mountain bike suspension usually comes in two flavours, coil and air, with the former offering greater sensitivity at the cost of extra weight and the latter providing more adjustability.

We have answered the question of how much suspension travel you need elsewhere, but if you're just getting started it's best to go for a mid-travel bike to suss out the riding you prefer.

Geometry

Finlay Anderson / Our Media

The geometry of a mountain bike is largely dictated by which discipline it’s made for, whether that’s a fast and responsive cross-country bike, a slack downhill race rig for gnarly trails or anything in between.

For the sake of simplicity, we won’t go into the specifics of geometry here – it's another complex area of mountain bike tech.

However, you can check out our ultimate guide to bike geometry if you want to learn more.

Wheel size

29in, 27.5in and 26in mountain bike wheel sizes
Larger wheels make it harder to accelerate and are less quick to turn. - BikeRadar

For a long time, 26in mountain bike wheels were the standard, but with the exception of dirt-jump and slopestyle bikes, they’ve been phased out in favour of larger, faster-rolling hoops.

Any new adult bike will likely come with either 27.5in (also known as 650b) or 29in-diameter wheels.

29er wheels have the advantages of carrying momentum better, rolling over obstacles more easily and providing more traction (due to the longer contact patch of their tyres).

The disadvantages are that the bigger wheels accelerate slower, take more effort to slow down and are harder to initiate a turn with.

This isn’t a problem in most scenarios, but if you have quite a dynamic riding style or like to ride trails that are tight, twisting and steep, 650b can be preferable.

Mullet bikes use different-sized wheels at either end of the bike, most commonly a 29in front wheel for speed and rolling over obstacles and a 27.5in back wheel for sharp handling at the rear.

Frame material

Carbon fibre is used for a lot of high-end mountain bikes. - Ian Linton / Our Media

You have four main options when it comes to frame material for bikes: aluminium, steel, titanium and carbon fibre.

Aluminium is the most commonly used frame material for mountain bikes because it offers a good balance of strength, weight and cost.

Cotic Jeht Silver Mullet full suspension mountain bike
Steel bikes are less mainstream than aluminium and carbon fibre. - Andy Lloyd / Our Media

Steel is a popular choice with smaller boutique brands, not only because it’s widely available and easy to work with, but also because the same strength can be achieved with thinner-walled and smaller-diameter tubes, resulting in a desirable amount of bump-absorbing ‘compliance’ (flex). This is particularly applicable to hardtails.

Titanium does the same with less of a weight penalty, but expect to pay upwards of £2,000 for a titanium frame.

Carbon has long been one of the buzzwords used to ‘upsell’ to bike buyers. To some extent, this is justified, because carbon fibre gives designers near-limitless control over frame shapes and ride characteristics, as well as the potential to build an incredibly light and strong chassis. This is important if you're choosing a featherweight XC race bike.

Cheaper carbon frames aren’t necessarily laid up with the same care and attention to detail, though. Also, be aware that at lower price points, brands will often spec cheaper build kits to prevent the complete bike looking too expensive compared to the next (aluminium) model down.

A better-specced aluminium bike will almost always ride better than a carbon frame decked out with cheap kit.

Mountain bike specifications to consider

  • Dropper posts: Many mountain bikes now come with dropper posts. These enable you to drop your saddle via a remote on the handlebar so you can more easily move your weight around your bike.
  • Wheels: Lightweight mountain bike wheels will make acceleration easier, while heavier ones will tend to fend off rock strikes more easily. Wheels are often something riders look to upgrade on a bike.
  • Disc brakes: Most mountain bikes will feature disc brakes, with the better ones using a hydraulic system as opposed to cable-actuated. Two-piston designs are usually enough for trail use, but it's best to look at four-piston models for enduro and downhill.
  • Pedals: Many mountain bikes won't be supplied with pedals, so it's best to pick your own. Clipless pedals keep your feet attached to the bike using a locking mechanism, increasing efficiency and guaranteeing foot placement, while flat pedals enable you to easily remove your foot and are good for learning the basic skills.
  • Tyres: This is one of the most important parts of the bike, being the only component that should make contact with the ground. Lighter tyres will feel zippier when accelerating, though this usually comes at the cost of puncture protection.

Women's mountain bikes

Most brands sell their bikes as unisex. - Finlay Anderson / Our Media

Some brands offer women's specific mountain bikes, such as Giant's Liv and Scott's Contessa range.

These bikes usually feature geometries and component choices that are designed for the female anatomy and should, in theory, result in a more comfortable ride than on unisex bikes.

Finding the right-size mountain bike

Finding the right size of bike is important because it will give you more confidence. - Steve Behr / Our Media

Getting a bike that fits you properly is extremely important. Not only will it ensure you're more comfortable on the bike, but you'll also be able to ride the bike to your maximum potential.

Our guide to mountain bike sizing is a good starting point – but remember, geometry and sizing aren’t consistent between brands, so always make sure to check the measurements. Don’t be tempted to compromise on fit.

If it isn’t quite right for you – the top tube’s a little short or you can’t get the seat low enough, for example – it’ll affect your fun far more than a fancy paintjob and a posh suspension fork. Riding the correct-size bike will also help you position your body on technical terrain.

If this is your first new bike in a while, it might surprise you how much longer they’ve got in recent years. This isn’t because we’ve all suddenly got taller, but because designers have figured out that stretched-out bikes with slacker head angles handle better at speed.

Any initial awkwardness you may feel when trying to manoeuvre a bigger bike around will soon disappear (assuming it’s the right size for you) and you’ll wonder how you ever managed on that cramped little bike you had before.

Traditionally, bikes were sized by seat-tube length. This is still an important factor, because you need to make sure you can get the saddle to an efficient height for pedalling, as well as drop it out of the way for descending.

However, the advent of long-travel dropper seatposts has permitted bike designers to reduce seat-tube lengths. As well as giving more freedom of movement, this enables riders to ‘upsize’ to a larger frame if they want more length, or vice versa.

Perhaps the most important metric when it comes to how big a bike will feel to ride is its ‘reach’ – the horizontal distance from the centre of the bottom bracket to the centre of the top of the head tube. This measurement gives a good indication of how stretched out you’ll feel when standing on the pedals.

From surveying our team of MBUK and BikeRadar testers, we found the interesting correlation that our ideal reach in millimetres was consistently between 2.6 and 2.7 times our height in centimetres. This calculation should give you a good starting point.

It’s often best to head down to your local bike shop to try the bike you’re looking at in person. If possible, try to arrange a test ride so you can see how the bike feels on the trail. Many brands have demo days, where they bring their entire range along for potential customers to try.

As a general rule, if you’re after a high-end bike, many shops will be happy to tweak certain components such as the saddle, tyres or grips to the ones you prefer if it means they can seal a deal.

With online or direct-sales bike shops, you don’t get the option to try before you buy, but most have a robust returns policy if you decide you’re not happy with the fit of your new machine.

Still haven't found what you're after?
