On this page, we will introduce the different mountain bike types.
Mountain bikes have developed a lot since we first started seeing them 50 years ago. From fat tire cruiser type bikes made by Schwinn, to the capable modern machines we have today, a lot has changed!
In the 70s, Gary Fisher, who was the godfather of mountain bikes, introduced the first proper mountain bike.

1. MOUNTAIN BIKE (FRAME) TYPES
The three main mountain bike frame types:
Frame Material Overview: Steel vs Aluminum vs Carbon vs Titanium
A Rigid MTB
A rigid mountain bike has a rigid frame which means there’s no suspension whatsover.
Although there’s still a small following to this bike type in the mountain biking community, a rigid MTB has some advantages – such as not losing any extra energy one would need on a suspension bike. There’s little to no give to the ride, and it is the responsiveness that this bike type is preferred for. All of the momentum is well carried over by the wheels, whereas you’d lose quite a bit of energy on the suspension
The main reason people buy rigid bikes today is for the fun factor and kind of a retro feel. Rigid bikes require more attention for picking the right line compared to other types of mountain bikes, making a seemingly easy trail a more technical experience.
Who to get one?
Rigid bikes are suggested for someone who wants to stick to the roots of mountain biking, or for someone who just has some fun being extra picky choosing with line choice. If you are looking for a rigid mountain bike – check out Surly Bikes!
Trial, Dirt Jump and BMX bikes have rigid forks
Advantages of a Rigid Mountain Bike
- Lighter – as there’s no extra weight that suspension adds.
- More efficient to keep the momentum
- Lower maintenance cost
- Bumpy, hard on the wrists
Hardtail Mountain Bike
The term hardtail stands for mountain bikes mountain bikes a with front suspension.
The same bike geometry is also found on many hybrid and electric bikes as it absorbs the bumps and makes the ride much more comfortable. In terms of mountain biking, the lack of rear suspension makes hardtail MTBs more efficient to pedal (extra cushion requires more energy). Although not as efficient as rigid mountain bikes, and not as comfortable as full-suspension bikes, there’s a large following to hardtail mountain bikes.
Suspension on the front also helps to prevent your hands from getting too sore on longer rides!
Hardtail MTB Fork Travel Range
Average suspension travel on a hardtail mountain bike is between 80mm to 140mm, although the most common travel is 100mm to 120mm.
The two main types of front suspension forks – Air fork and Coil fork.
Coil Spring is a rather cheap and basic technology in terms on mountain bike fork industry. Most lower-end bikes come equipped with a coil-type fork. This type is often found on not as demanding cycling disciplines such as hybrids, e-bikes, etc. They are generally maintenance free and basic, great for recreational cyclists
*Downhill mountain bikes, which take the most beating on the mountains, most always use a coil shock on the rear.
Air suspension tends to be lighter with more precise to adjust.
Suspension Fork Features
Rebound – Higher rebound – faster return. Lower rebound – slower and cushier travel to its extended state. To properly set the rebound on a bicycle fork – it should be adjusted so that it wouldn’t jump back up without a “clunk” when you lift the front end while riding.
Compression (Damping) – can be adjusted only on a air fork, a compression stands for the stability of the fork travel while riding. It basically adjusts the response.
Lockout – Allows to lock out the fork which is useful when riding on paved roads. It is not advised to use the lock when riding on trails as it can damage the fork!
Advantages of a Hardtail MTB
- Lighter and more efficient than a full suspension
- Much more comfortable than a rigid MTB
- Best all-rounder mountain bike
- Good climbing capabilities
- Cheap hardtail mountain bikes have poor performance
- On rough terrain, a hardtail mountain bikes is not as comfortable as the full suspension
Full Suspension (FS)
Full Suspension bikes have two shocks – on front and rear.
A full-suspension bike is a bike that has both front and rear suspension. Sometimes they are also called the dual suspension bikes. Any full suspension bike you come across will be a mountain bike.
These are meant for riders who regularly find themselves on rough off-road trails. Full suspension bikes are ridden for leisure and racing more than they are for transportation.
Travel length on front and rear can range from 80 – 200mm, depending on the riding preferences and mountain bike type.
Depending on the model, there are different ways to adjust the rear shock just like the front fork:
A rear shock can have rebound and lockout, as well as many other features such as high speed and low-speed compression.
Advantages of a Full Suspension MTB
- Makes uneven terrain feel smoother
- Great for riders with previous injuries
- Suspension lockout for more efficient climbing
- Generally heavier than HT, and Rigid bikes

2. MOUNTAIN BIKE TYPES
Mountain biking has divided into several disciplines that we want to introduce to you. Personal riding preference will decide what category you fit into and what bike to choose. Let’s check out the different discipline types of mountain bikes.
XC – Trail – All-Mountain – Enduro – Gravity – Electric MTBs – Fat – Gravel – Dirt – Trials
Cross Country (XC) Mountain Bikes
70-100mm travel range
Cross country bikes have the least amount of travel compared to other mountain bikes. XC bikes are preferred to their fast, zippy riding qualities. These bikes are designed to be ridden on anything from city streets, to intermediate mountain bike trails. They pedal well and usually absorb small bumps with nicely.
These bikes are meant for fast trails, where you need the right amount of cushion and rigidity.
- Available in hardtail, full-suspension or a rigid frame type
- 27.5” or 29” wheels
- 80 – 120mm suspension travel
- Relatively steep head angles (69-degrees or steeper)
- The prices range from $500 to $9,000+
Trail Mountain Bikes
100 – 140mm travel range
One of the most popular all-rounder mountain bike to get – trail mountain bikes are basically cross country bikes with slacker geometry. Slightly heavier than XC bikes, Trail bikes have longer suspension range which works well on rougher trails.
Trail bikes will handle small jumps and descents quite well. What plays a big role here is the comfortable geometry which allows to ride long and short rides efficently.
- 27.5” or 29” wheels
- Slack head tuge angles around 67 degrees
- Prices start at $800 for a decent one
Enduro / All Mountain Bikes
150 – 180mm of suspension travel front and rear
Enduro is one of the most advanced mountain biking disciplines.
Climbs, descents, fast and technical trails – enduro bike can handle pretty much anything. Only a notch below the downhill bike, Enduro bikes have 1×11 or 1×12 speed drivetrains, fully adjustable suspension, and slack geometry. Enduro bikes thrive in trails that require maximum traction and customized suspension tune-up for the best possible performance.
Unlike a downhill bike, enduro bikes are designed to ride up the hill, and later down the hill as well. Only experienced riders will make the most of an Enduro bike.
Mullet bike is a type of mountain bike with mixed wheel sizes. Mostly the mixture is 27.5″ and 29″, although 26″ can be blended in some times as well.
- 95% full-suspension, 5% hardtails
- Mostly 27.5” wheels, sometimes 29” size as well
- Tubeless wheels & tires
- Slack geometry – head tube angle is generally less than 67 degrees
Downhill / Freeride Mountain Bikes
180-210mm on the front, 170-250mm on the rear
Downhill and freeride bikes are designed to take the beating, full time! Steep drops, huge jumps, gnarly terrain, and all the previous at the highest possible speed.
These bikes are engineered to handle a mass amount of stress without a failure, for example, even downhill tires are made of using extra resilient to prevent punctures.
The geometry and parts on downhill bikes have been designed so that riders can go over obstacles with maximum traction.
To summarize, downhill bikes are only meant to go downhill, and on specific trails. They are not comfortably ridden as everyday all-around bike.
- Always a full-suspension bike
- Usually 27.5” wheels (rarely 26” or 29”)
- Slack head angle of less than 65 degrees
- Single front chainring, 6 to 8-speed drivetrains are standard
Electric Mountain Bikes
Electric mountain bikes come in all sorts of forms and variations, but the majority of them rock a full-suspension set-up.
Although good-quality E-MTBs start from around $3,500, there are cheaper hardtail versions available as well. A mid-drive motor is a must, although cheaper electric MTBs come with a hub motor as well. Many of the eMTBs are built to offer a better assisted power when climbing or simply going for longer routes with some energy leftover.
If you aren’t really sure of what to expect, we’d recommend looking at the bottom of the best-of article to get more information
- 27.5″ and 29″ wheels
- Mid-drive motors
- 1x front chainring, 1×12 is a standard
Rigid frame, 26×4″ tires
Fat bikes were originally built to handle sand and snow, but the demand has widen the specter for many recreational cyclist.
Although those chunky tires and a rigid frame might give a false signals that they are hard to ride, it is actually the other way around. The large tires offer a lot of comfort, and the rigid frame helps to keep the momentum. These days more and more recreational cyclist have found their calling in the fat bike rides.
A typical fat bikes comes in a rigid frame and 26″ wheels, but due to the large tires, it is equivalent of a 29″ wheel. Most fat bikes are light in weight and offer a ton of comfort on rugged trails which can’t be passed by with a standard-size mountain bike tires.
If a fat bike mountain bike isn’t something for you, there are also many more variations of bikes on fat tire sizes, such as cruisers, folding, electric and much more.
- 26×3.8″ – 26×5″ wide tires
- 20″, 26″, 27.5″ wheels are around, although the 26″ is the most common
- 1x single front chainring
- Mechanical or hydraulic disc brakes
Similar to touring bikes, gravel bikes are basically performance road bikes designed to tackle light to demanding trails. Most gravel bikes come on road bike geometry and 650b wheels (27.5″) with knobby tires. You’ll notice that most high-end mountain bike brands have also a gravel bike on their listing, as it truly is a perfect alternative for a 70% mountain-, and 30% road bike enthusiast.
Unlike cyclocross bikes, which are performance gravel bikes. gravel bikes also have eyelets for panniers and water bottles.
Gravel bike makes a perfect companion for commuter cyclists who are looking for speed, comfort and accessibility to turn off the paved roads as well.
- Ideal mixture of road and mountain
- 650b wheels
- Mechanical / Hydraulic disc brakes
- 1x drivetrain
Dirt Jump Mountain Bike
Dirt / Park / Freestyle
Dirt jump bikes attract the bunch of adrenaline junkies who are looking to master jumps and trick on custom-made parks and dirt jumps. Whether it is a concrete skate park, or custom made jumps, dirt bike riding isn’t for the faint hearted, that’s for sure! Dirt jump bikes are basically built to do the same tricks as BMX bikes, while having a better reach and speed for certain descents, jumps, landings and of course – tricks.
- 26 wheels
- Aluminum = Lighter / Steel = More durable
- Rigid or with front suspension
- Super strong components, especially hubs, wheels, frame, etc.
Trial Mountain Bicycle
Bike trials is not very well-known as a mountain bike type, although it certainly is one. Trial biking consists of a obstacle course where the goal point is to make a certain trick, or jump a gap without setting foot to ground. The stunts generally starts from standing still on a bike.
In this discipline, a cyclist has mastered bicycle control to a high degree.
Trial bikes might seem simple in their build, but they do cost a fortune! Every single detail about the bike is put together in order to offer minimum weight at the best durability.
- Advanced balance, bike handling and physical stamina is needed
- Super durable components – every single one!
- 20″, 24″, 26″
