Trek Marlin 4 Gen 2 Review: A Capable Budget-Friendly XC MTB

trek marlin 4 review

Trek Marlin 4 is the second cheapest model in Trek’s mountain bike range, at just $630. 

This stylish, modern-looking hardtail is a solid introductory bike for day-to-day riding, commuting, and leisurely weekend spins on gravel and dirt trails. 

Although it looks the part, the Marlin 4 can’t handle actual mountain trails, as the low-performance fork won’t take much abuse. 

This Trek Marlin 4 review will provide a detailed look at the bike, its strengths and weaknesses, and the type of rider who should buy it. 

What Is the Weight Limit on a Trek Marlin 4?

The weight limit on a Marlin 4 MTB is 300 lbs, which includes the bicycle, rider, and cargo. The bike weighs just under 32 lbs, leaving around 268 lbs for the rider and cargo. 

  • Sleek design with internal cable routing
  • Shimano drivetrain
  • Cheap 
  • Heavy, low-performance fork

Trek Marlin 4 2023 Full Specs

Trek marlin 4 gen 2 full review.

The Trek Marlin 4 2022 is the same as the 2023 model. It has a basic 3×7-speed Shimano Altus/Tourney groupset and Tektro mechanical disc brakes, a typical pairing for the price range. The SR Suntour XCE 28 isn’t worth much on mountain trails but takes the sting out of bumpy gravel trails and roads. 

This section will cover the features and components that make the bike stand out in its price category. 

Is the Trek Marlin 4 a Trail Bike?

The Trek Marlin 4 is not a trail bike. Trail mountain bikes typically have above 120mm of travel, and the majority of models are full-suspension. Instead, the Marlin 4 is a light-duty off-roader better suited to urban riding and gravel trails.

If you want a proper trial bike, check our list of the best full-suspension mountain bikes out there.

Stylish Alpha Silver Aluminum Frame

The whole Trek Marlin series uses the same Alpha Silver aluminum frame. However, at less than half the price of the premium model, this frame is a notable strength of the Marlin 4. 

Marlin 4 Gen 2 internal cable routing

Marlin 4 has full internal cable routing, which is a popular feature that not all mountain bikes in this price range offer.

Trek’s Alpha Silver frame comes from years of materials innovations and design expertise, resulting in a balanced ride quality that balances stiffness and compliance compared to the overly stiff aluminum frames typical of this price range. 

This frame also has sleek internal cable routing that gives the bike a higher-priced finish and mounts for a rack and kickstand for commuting or even light bikepacking. 

What Is the Difference Between Trek Marlin 4 and 5?

There isn’t a big difference between the performance of the Trek Marlin 4 vs. 5. The Marlin 5 has a slightly more robust fork, improved 2×8-speed gearing and hydraulic disc brakes, and a slightly lower weight. However, the Trek Marlin 4’s price is $110 lower than the Marlin 5 . 

Progressive Sizing

The Trek Marlin 4 2023 comes in seven different sizes, with almost two feet in between the shortest and tallest recommended heights. The company uses progressively sized wheels and components and a modified top tube for the smaller bikes to deliver the same performance for each rider . 

The XS and Small sizes both have a curved top tube which lowers the standover height, which shorter riders have issues with, and ‘Smart Wheel Sizes’ means the smaller sizes get 27.5″ wheels instead of 29ers. In addition, the brake levers, handlebars, stems, and cranks all change throughout the size range. 

Reliable Bontrager Componentry 

Trek Bikes’ in-house brand Bontrager provides the whole build kit aside from the groupset and fork. These are well-made components that will stand the test of time. In addition, they are easy to replace by visiting the Trek online store.

Premium all-black finish and quality Bontrager parts help Trek Marlin 4 look good and provide better value for the money.

It’s worth noting that the saddle, handlebars, seatpost, and stem are the same across the five Marlin bikes, which benefits the Marlin 4 and increases its value as it is the cheapest. 

Trek Marlin 4 Gen 2 Sizing Chart

  • XS — 4’9″-5’1″ / 145-155cm
  • S —  5’1″-5’5″ / 155-165cm
  • M —  5’5″-5’8″ / 165-173cm
  • M/L — 5’8″-5’11” / 173-180cm
  • L —  5’11”-6’2″ / 180-188cm
  • XL —  6’2″-6’5″ / 188-195cm
  • 2XL — 6’5″-6’8″ / 195-203cm

Who Is Trek Marlin 4 Gen 2 Best Suited For?

The Trek Marlin 4 mountain bike is suitable for urban riders, commuters, and anyone who enjoys riding on light off-road paths, fire roads, and gravel trails. 

trek marlin 4 with accessories

By equipping Trek Marlin 4 with a rear rack and kickstand, you can use it for commuting, running errands, or even bikepacking.

The level of components is typical for this price point, and they perform as expected. However, there are clear limitations to this bike’s capabilities off-road. So if you’re looking for a capable XC mountain bike, this isn’t it. 

Anyone looking for a cheap, reliable run around that doesn’t sacrifice style will appreciate the Trek’s Marlin 4.

Is Marlin 4 Gen 2 a Good Buy?

We believe the Trek Marlin 4 Gen 2 is an excellent buy in the ~$600 price range, easily competing with similarly-priced hardtails like the Cannondale Trail 8 or Co-op Cycles DRT 1.0.

Trek bikes are renowned for their reliability, and with the Marlin 4, you’re getting this reliability at an unbeatable price. And if that wasn’t enough, it’s got a sleek modern design that makes it look more expensive than it is. 

Consider the Marlin 4 if you want a Trek mountain bike that doesn’t break the bank and will get you from A to B in comfort and style.

Trying to decide whether to buy the Trek Marlin 4? Then you’ve come to the right place.

Buying a new bike is never easy. So I’ve got a ton of detailed info in this review to make the whole decision making process a little easier for you – basically I’ve got everything you need in this article to enable you to go, “Yep, this is the right bike for me”, or “Nope, gotta move along to the next one on the list”. Firstly, I’ve got a full spec list for the Marlin 4, listing every component, so that you can compare the bike against others. Either other bikes from the Marlin range ( like the Trek Marlin 5 or the 6 ) or maybe even a different type of bike, such as the FX or Dual Sport ranges from Trek . I’ll then take you an in-depth write-up of the Marlin range, and the Marlin 4 in particular, so you can see what I think of this bike.

But, maybe you don’t have time for all that detail? Maybe you just want to know whether it’s a good bike, so you can either buy it or move on. Hey, I’m not going to be offended! Life is short and we’ve got bike rides to go on after all. So, here’s a quick spoiler. If you want a great entry-level mountain bike for light-duty trails, that’s also a great all-rounder and perfect for trips to the beach/grocery store or commuting to the office. AND you want all that at a stunningly-low price. Then the Marlin 4 is a great choice. If you want all that in a bike that’s a little lighter, a little more trail-ready, and you’ve got some extra coinage in your back pocket, then I’d suggest pushing the boat out slightly further and getting the Marlin 6.

Whichever Trek Marlin you choose, however, you’ll be riding around on it with a big grin on your face.

Now, spoiler over, if you’re able to stick around for a little longer we’ll go into a deep dive on the Marlin 4. Prepare to drool.

Trek Marlin overview

Trek’s Marlin range of bikes are known as mountain bikes, MTBs (for those looking for something that’s a little less of a mouthful) or “hardtails” (for those looking to appear a little more intelligent). For the rest of us, it’s useful to know that hardtails are bikes that have suspension on the front forks, dampening the trail vibration before it reaches your hands, wrists and arms. Full-suspension or ‘full-sus’ bikes are mountain bikes that have suspension on both the front and rear forks. Unless you’re an intermediate to advanced mountain biker then I’d recommend steering clear of full-suspension bikes. Top-of-the-range full-sus bikes are fantastic to ride but they come with a hefty price tag. Full suspension bikes that are more affordable tend to have rear suspension that is lower quality (therefore more prone to failure) and heavier (so you’ll have a harder time pedaling up hills).

Hardtails, like the Marlin range, are a great all-rounder. They’re sufficiently rugged to get around most beginner-to-intermediate bike trails with ease (and a grin on the rider’s face) and they’ll also take you to places where full-suspension MTBs would be completely out of place: the beach, the grocery store, the park at the weekend, and the office during the week. And that makes them a really versatile option for many people.

Trek’s Marlin range encompasses seven different models. These go from the entry-level Marlin 4 through consecutive numbers to the top-of-the-range Marlin 8. With these male/unisex bikes being complemented by the female-specific, Marlin 5 Women’s and Marlin 6 Women’s.

When I was researching the Marlin range online, I came across one comment which really summed it up: “Bang for the buck!!!!” Clearer the owner of this Trek bike was very enthusiastic about his purchase, though I did feel that the fourth exclamation mark was a little over-the-top. But, whatever, all the Marlin models are great bikes.

And, not only are they great bikes, by they’re also fantastic value-for-money. From the Marlin 4 at a touch over $500 to the Marlin 8, which is only around $1200. I say ‘only’ because, in the world of mountain bikes this is an absolute bargain.

So, the Marlin range is a series of hardtail mountain bikes, with great specifications, at a range of price points, that all represent excellent value. Let’s dive in and take a closer look at the Trek Marlin 4.

Trek Marlin 4 review

Pros: Lowest price in the Trek Marlin range; great ‘bang for your buck!!!!’ Cons: non-locking front suspension fork, narrower range of gears, heavier than other Marlins

Let’s start with looking at who this bike is for.

The Marlin 4 is a great all-rounder. It will take you on to plenty of backcountry trails, where you can have as much fun as you want on bike trails with loose stony or muddy surfaces. Returning home with a muddy grin on your face. Give it a clean down afterwards, pull on your work clothes, and it will take you to the office, with another grin plastered on your face (though, hopefully, less mud). In between, it will give you a lift to the beach, the grocery store, and around the local park to chase your kids.

If you’re new to cycling, then you’ll be hard pushed to find a better option than the Marlin 4, however you might not appreciate how versatile it is. Compare it to a road bike – the kind that you see spandex-clad speed merchants hunched over – or a full-suspension mountain bike and you’ll soon notice the differences. The Marlin 4 has a much more relaxed and upright riding position than a road bike does. Sure, you’re unlikely to go as fast as on a road bike, but you’ll ride in considerably more comfort. And you won’t be hitting the ‘Double Black Diamond’ bike trails on a Marlin 4, but then you might also have fewer trips to the Emergency Ward at your local hospital. Swings and roundabouts.

If you fit this description – you’re looking for an all-rounder bike and aren’t looking to achieve land speed records in your spandex or cycle down near vertical trails, then the Trek Marlin 4 is a great choice for you. If, however, you’re looking to spend more time on tougher and more rugged bike trails, then it’s worth heading a few notches up the range towards the Marlin 7 or Marlin 8.

Check out the specification list at the top of the page and you’ll see that the Marlin 4 has a great aluminum frame (which is light and strong) It has front suspension forks which reduce the amount of vibration from a bumpy trail surface from reaching your fingers and wrists. The Bontrager XR2 Comp tires give good grip and cornering on loose surfaces, and yet still feel smooth to ride when you’re on pavement. Top this off with 21 gears for getting you up hills easily and down hills quickly and you’ve got an excellent package.

The base model pricing of the Marlin 4 doesn’t come without a couple limitations though. First up, the Tektro disc brakes are mechanical rather than hydraulic. That means that they use a cable to pull the brake pads against the brake discs, rather than hydraulic brake fluid. These are still great brakes, giving you all the stopping power you need, however they add weight to the bike vs their hydraulic siblings. And bike weight is the second issue. Compared with the more expensive Marlin 8, the Marlin 4 is nearly three pounds heavier. Cycle for long distances or up lots of hills and you’ll definitely notice this extra weight. But, then, if you have the funds available and want extra spec, there are plenty of more advanced models in the Marlin range to choose from (Hint: I love the Marlin 6).

To sum up, if you’re looking for a great first bike for all-round use, taking you on regular trips to the trails, parks, beaches, and office, then the Marlin 4 is an awesome choice.

What is the difference between Trek Marlin 4 and 5?

One step up from the Trek Marlin 4 is the Marlin 5. With just over a hundred-dollar difference, is it worth stumping up the extra cash to trade-up?

Well, there are some general improvements to the components on the Marlin 5. With the key ones to note being the front forks, gearing, and brakes. Suspension on the front forks can now be locked. That means you choose when the forks are bouncy (to soak up rough terrain) or fixed (to make it easier to throw your weight behind uphill ascents). It’s a feature that I’m a big fan of.

Gearing has been changed so that, instead of 3×7 on the Marlin 4, there are now 2×8 on the Marlin 5. There are fewer gears, although in practice you won’t notice this. What you may notice is that there are likely to be fewer mechanical issues with 2-ring gearing than 3-ring in the long term – fewer issues meaning less downtime and less repair cost.

Finally, the brakes on the Marlin 5 use hydraulic brake fluid rather than the cable-pull mechanicals of the Marlin 4 brakes. These are lighter and are what you find on high-end mountain bikes.

Are these worth paying the extra for? Well, I ride a hardtail mountain bike that has a locking front suspension and it’s a feature that I really like as I use my bike on plenty of uphill smooth surfaces (as well as rougher trails). Doing those same uphills without locking suspension is harder but if your uphills are few are far between then this may not be an issue for you and therefore not worth paying for.

In this article, I’ll help you navigate the Trek Marlin mountain bike family by comparing the Marlin 4, 5, 6, 7, and 8. You’ll learn about the differences between each model, who they are best suited for, and more. 

KEY TAKEAWAY

Trek Marlin mountain bikes are ideal for beginners and intermediate riders. They are suitable for cross-country-like terrains. They have relatively short fork travel and no rear suspension, so I recommend avoiding too demanding terrains and technical trails. For those, check out Trek Roscoe .

Marlins differ only in components. I believe the Marlin 6 provides the best value for money because it has a modern 10-speed 1X Shimano Deore drivetrain and Tektro hydraulic disc brakes, and it’s priced in the middle of the entire Marlin range.

Plus, I’ll tell you which model gives you the best value for your money to help make your decision easier.

Trek Marlin 4 vs. 5 vs. 6 vs. 7 vs. 8

The following table summarizes the main differences between all Marlins that belong among the Trek hardtail mountain bikes .

Marlin Pros & Cons Summary

I summarized the pros & cons of the Marlin series below.

Marlin Pros

  • Affordability
  • Availability in multiple sizes and colors
  • Compatible with racks, kickstands, etc.
  • Partially internal cable routing
  • Lifetime warranty

Marlin Cons

  • Unsuitable for demanding MTB terrain due to the short fork travel (100mm)
  • Relatively heavy
  • No full-suspension
  • No dropper post (except Trek Marlin 8 Gen 3), Gen 3 models are compatible with dropper posts

Marlin Main Features

Let me now explain the most important features of the Trek Marlin bikes.

Frame and Geometry

All Marlin bikes have the same aluminum cross-country frame , available in many sizes and colors that vary between models.

The XXS-S sizes have a differently shaped top tube , which is curved to increase the clearance between the rider’s crotch and the frame. This allows riders with shorter legs to stand over the bike more comfortably, for example, when stopping.

Two Trek Marlins (size S and smaller have 27.5" wheels and curved top tube, bigger sizes have 29" wheels).

The frames of Gen 2 Marlins have a standard cross-country geometry , which provides a comfortable riding position and easy pedaling uphill and downhill. It also gives you easy maneuverability and visibility.

On the other hand, it’s not quite suitable for steep descents and challenging terrain – especially without a dropper seatpost.

The Gen 3 Marlins have a trail geometry (wider wheelbase) that provides more stability, especially when riding downhill. This geometry is similar to the Trek Roscoe .

Trek Marlin Gen 2 vs. Gen 3 geometry compared using the bikeinsights.com tool.

Lastly, it’s worth noting that the bike’s partially internally routed cables improve its overall appearance.

One of the biggest limitations of Marlin bikes is their front fork suspension. These bikes are not primarily designed for challenging terrain but rather for those who want a versatile bike that can handle various surfaces.

Trek Marlin 4-8 front suspension: SR Suntour XCE 28 (coil spring) 100mm travel, SR Suntour XCM 30 (coil spring) 100mm travel, SR Suntour XCM 30 (coil spring) 100mm travel, RockShox Judy (coil spring) 100mm travel RockShox Judy Silver (Solo Air spring) 100mm travel.

All Marlin bikes have a suspension travel of only 100mm, which is capable of absorbing small bumps. However, this is not ideal for riding on rocky trails, especially not for downhill riding.

Therefore, if you want a bike for more challenging terrain, choose one with longer travel (for example, the Trek Roscoe series ).

All Marlin bikes’ forks have suspension lockout. Lock them when riding on smooth surfaces to reduce energy loss when pedaling.

Wheels and Tires

The wheel size varies depending on the frame size. Frames smaller than size S are equipped with 27.5″ wheels, which are more agile and accelerate faster than 29″ wheels. Frames size M and larger have 29-inch wheels, which are more stable and better at maintaining speed.

All models have the same rims (Bontrager Connection, double-wall) except for the highest model, the Marlin 8 , which has Bontrager Kove rims. The former rims are not tubeless-ready, while the latter are.

The same goes for the tires. The highest model already has tubeless Maxxis Ardent tires, while lower models have Bontrager XR2 Comp inner tube tires.

The groupset is one of the main areas where the different models vary, and it’s probably the deciding factor for many people.

They differ primarily in the number of gears . Modern mountain bikes mainly use 1X drivetrains , which are popular due to their simplicity for maintenance and shifting. They are also lighter than 2X or 3X groupsets .

On the other hand, they offer fewer gears, so you may not always find the ideal one for your preferred cadence.

I recommend choosing from the 1X drivetrains available on Marlin 6 and higher models. This way, you won’t have to think too much about shifting and cross-chaining.

Another difference between the Marlin models is their brakes. The entry-level Marlin 4 uses mechanical disc brakes , while higher-end models have Tektro or Shimano hydraulic brakes .

Trek Marlin with Tektro MD-M280 mechanical disc, Tektro HD-M275 hydraulic disc, and Shimano MT200 hydraulic disc brakes.

Better brakes provide higher braking power. However, if you mainly ride on flat terrain leisurely, you don’t have to worry about a lack of braking performance.

Quality brakes are especially important if you plan on riding technical descents, so consider your riding style.

To learn more about disc brakes, read my article comparing mechanical and disc brakes .

Marlin frames have mounts for kickstands and racks , so you can easily install these accessories.

You can also use a Blendr stem , which is a mechanism that allows you to easily attach things like lights, speedometers, or bike computers.

The last detail is the lock-on grips that are easier to install and replace than slip-on grips.

So, which bike from the Marlin family is the best?

In my opinion, the Marlin 6 is the best choice because it has a modern 10-speed 1X Shimano Deore drivetrain and Tektro hydraulic disc brakes. Plus, it’s priced in the middle of the entire Marlin range.

Another option to consider is the Marlin 5 , which is similar but has a Shimano Altus 2×8spd drivetrain, is lighter, and more affordable.

On the other hand, I recommend avoiding the Marlin 4 because it uses the outdated 3X drivetrain. The value of the Marlin 8 is also questionable, as you can get mountain bikes with better components in this price range.

Trek Marlin FAQ

Trek Marlin mountain bikes are perfect for people new to mountain biking, recreational riders, and those who use their bikes to commute. Marlins are reasonably priced, versatile, and comfortable. They come in various sizes and colors, so you can always find the best fit. However, they have entry-level components that are unsuitable for challenging terrain because their fork travel is short. Check out Trek X-Caliber and Procaliber families if you want a better XC bike.

Marlin bikes (4 to 8) differ mainly in components like the groupset, front fork, brakes, weight, and price. I recommend reading this entire article for more information and a helpful comparison table.

The geometry is the main difference between Trek Marlin Gen 2 and Gen 3. Gen 3 Marlins have a trail geometry, meaning a wider wheelbase provides better stability. Gen 2 has a standard XC geometry. Marlin Gen 3 bikes are heavier, have wider tires and different wheels, and are available in different colors. They are also more expensive (except for the Marlin 7 Gen 2 vs. Gen 3). Most other components, like the groupset, suspension fork, saddle, grips, etc., are the same.

Marlin mountain bikes are a great choice for those who need an affordable bike. They are versatile, allowing you to ride on surfaces like paved roads with potholes, dirt, forest roads, and easy trails. Plus, they have mounting options that make adding accessories like racks and kickstands easy. The high-volume tires and front suspension provide a comfortable ride, better than what you’d get on a gravel bike , for example.

Marlin mountain bikes come with entry-level components that may limit their performance for serious mountain bikers. The groupsets are not as fast and effective, and the fork travel is limited to only 100mm. These bikes are also relatively heavy and don’t have a carbon frame option or a dropper post.

Trek Marlin 4 Review: Is It A Good Beginner Bike?

  • By Daniel Shakibaie
  • Mountain Bike , Trek Bikes

Trek Marlin 4 Review

Cycling is often seen as an elite sport thanks to the high price point for a great bike and quality biking gear. Fortunately, a lot of the big biking manufacturers (Trek included) have seen that and know how important it is to offer high-quality bikes that are a little more affordable for your average entry-level cyclist. 

The Marlin 4 is one of those bikes. A slightly less refined member of the Marlin line, it’s still a high-quality mountain bike from a trusted manufacturer, and it’s still more than trail ready. 

Let’s take a look at what this bike has to offer. 

Overview Of Trek Marlin 4

The Marlin 4 isn’t the first bike most people think of when they think of the Marlin line. Cyclists tend to gravitate toward the Marlin 6 , which offers a slightly fresher and more feature-rich bike. 

But that isn’t a problem because the Marlin 4 doesn’t need to be in the spotlight to perform. 

Instead of adding many bells and whistles, the Marlin 4 focuses on good bike mechanics from good construction principles to a well-balanced components to create a bike that can keep up with premium models, but without the higher price tags. 

Things to Consider Before Buying a Mountain Bike

Mountain bikes are a great choice if you’re looking to be able to explore the woods and trails near your home on a bike. They’re fantastic for hills and rough terrain, but you don’t actually have to live in the mountains to take advantage of mountain bike design benefits. 

Mountain bikes are designed to handle off-roading and riding away from the asphalt. They offer a smoother ride and better jump capacity than road bikes, but they are a similarly specialized bike. If you’re looking for a road commuter or a bike for light riding you might be better off with another design. 

That’s not because mountain bikes aren’t great bikes, they are! But getting a bike that’s designed for the way you’re going to use it helps ensure that your money is buying the features and benefits that will most help you as a rider. 

Features & Benefits

Now that we’ve talked a little about the Marlin line and mountain bikes in general, let’s dig into the details about the Marlin 4 and what you can expect from this affordable mountain bike. 

Frame

The frame on the Marlin 4 is made of Trek’s Alpha Silver Aluminum alloy. That means superior performance and great balance, but the Silver alloy is just a little heavier than their more expensive Gold alloy (Not that the metals are alloyed with silver or gold either one, those are simply the names of the finished metal)

This frame doesn’t have a lot of extras. It’s pretty much the basic frame. However, like the other models in the Marlin line, this frame does have the mounting locations for a bike rack and other accessories. You do get a kickstand and internal routing standard with this design though, both of which help keep your bike in good condition. 

Internal routing is especially important if you’re planning to hit the trails with your Marlin 4. Keeping the wiring internal helps prevent premature damage and can especially help prevent wiring from getting cut or damaged while you’re out. 

This bike is just a little heavier than many serious cyclists prefer, slightly more than 31 lbs. That extra weight does mean that it takes more horsepower to get this bike rolling, but it’s a good middle-ground for most beginners and even intermediate mountain cyclists.

Suspension System

Suspension System

The suspension system on the Marlin 4 is, like most of the bikes in the Marlin line, a little slimmer than many mountain bikers prefer. The suspension is mostly in the front Suntour fork, which offers 100 millimeters of travel. 

Suntour is a good brand when it comes to suspension, so while this fork might not move as much as you prefer, it will still absorb more of the impact on your bike that you’re likely expecting. It’s also a good fork for handling road vibration, which makes gravel riding and even riding on damaged pavement significantly easier. 

That said, it can’t compete with a full suspension system, including a suspension saddle in terms of performance. The Suntour XCE 28 suspension fork will smooth things out, but you’ll still feel some of the bumps and bruises along the way. 

Still, if you like a more natural feeling ride, minimal suspension can actually help you connect with trail riding. It’s good for making your ride a little easier to handle while also helping you learn how different kinds of terrain will affect your bike.

Wheel

The wheels on this bike are one area where we don’t have any real criticism. Considering the bike’s price point, it’s no surprise that it doesn’t come pre-loaded with a truly premium tire set, but the wheels are well designed and efficient. The 29″ wheel design is a little more aggressive than some of the alternatives, and double-walled rims add to the bike’s durability overall. 

The included tires give you a reasonably grippy tread but are also maneuverable and up to a little bit of cornering without too many problems. The big advantage here is that the tires are durable and up to quite a bit of active trail riding (and learning) before you’ll need to invest in replacements. 

Gear

This is where a lot of gear-loving cyclists don’t appreciate the design of the Marlin 4. However, if you’re in the camp that more gears aren’t necessarily better then this might be a design that appeals to you. 

The Marlin 4 has a fairly bare-bones drivetrain in terms of the number of gears it gives you. It’s only a 7-gear bike. 

However, that does give you a fair amount of flexibility as a trail rider. There are just enough gears to make climbing and dealing with different slopes more doable, but not so many that you’re likely to have trouble using your shifter effectively, even as a novice. 

More importantly, the Shimano drivetrain is a great option despite the limited gears thanks to its impressively smooth and consistent performance. Shimano not only offers consistent performance; their drivetrains are also easy to maintain and tend to last.

Brakes

Next to the frame balance and weight, brakes are possibly your most important feature, and they might be more important than the frame quite frankly. Brakes are your number 1 safety feature, and it’s important to have great brakes in good working condition to make sure you always have firm control of your bike. 

The Marlin 4 comes with a set of Tektro mechanical disc brakes which are, overall, a great option in this price range. They aren’t quite as effective as the more advanced hydraulic disc brake design, but they are still more responsive than linear-pull brakes. 

Mechanical disc brakes are also less prone to getting gravel stuck and potentially damaging both the brake and the rim, which is definitely a big concern for most mountain cyclists. These brakes will need less maintenance and are much less likely to be the reason you’re walking beside your bike, than linear-pull models. 

It’s nice for an affordable bike to see this kind of adaptation included even on the more budget-friendly models in this line. 

Is the Trek Marlin 7 a Suitable Bike for Beginners?

The trek marlin 7 bike review is essential for beginners evaluating their options. With its versatile features and durable build, this bike is an excellent choice for those starting their cycling journey. Its lightweight frame, smooth gearing system, and reliable brakes ensure a comfortable and safe riding experience. The Trek Marlin 7 offers beginners the perfect balance of efficiency, control, and affordability.

Social Proof

Overall cyclists rocking the Marlin 4 tend to say the same thing. It’s a great bike at an affordable price point, but that doesn’t mean it’s a fantastic bike. If you’re looking for a good beginner or intermediate option, working with a tight budget, and don’t mind losing some of the bells and whistles of more expensive models, Marlin 4 is the right bike. 

If you’re expecting competition level performance and to be a pro rider three days after opening the bike you might be better off with a more expensive model that offers more features and versatility. 

Social Proof 1

Alternatives

Of course, the Marlin 4 has quite a bit of competition, specifically from other bikes in the Marlin line! We’ve also decided to compare the Marlin 4 to a similar bike from another manufacturer to see how it holds up and help you decide which model is the right choice for you. 

Trek Marlin 4 vs Marlin 5

The Marlin 4 and the Marlin 5 are remarkably similar beasts. Both models use the same basic frame, wheel components, and have similar forks. However, the Marlin 5 does offer an expanded drivetrain of 21 gears. 

The Marlin 5 also features upgraded hydraulic disc brakes, but they are similar enough that the two brake designs offer similar performance value. 

Overall, the Marlin 4 is probably the better option if you don’t mind having a more limited gear drivetrain. But the Marlin 5 is only slightly more expensive, so it’s worth the upgrade if you prefer bikes with more gear options. 

Trek Marlin 4 vs Marlin 6

Unlike the Marlin 5, there are a few more upgrades when you’re talking about the Marlin 6. Again, both bikes use the same frame and the same basic wheel design. 

However, in addition to using the upgraded gear system, the Marlin 6 also offers a slightly better suspension system that’s designed to help smooth out the trail a good bit more than the suspension on the Marlin 4. It’s still just a front suspension system, but a little extra travel in the fork goes a long way. 

That said, the Marlin 6 is the more expensive of the two by a fair amount. It’s worth the extra money, but the Marlin 4 is still a fine bike if you’re on a tighter budget. 

Trek Marlin 4 vs Giant ATX 2

The Trek Marlin 4 is again a very similar model to the Giant ATX 2. The ATX 2 also uses an internal routing system on the frame, and weighs about the same as the Marlin 4. Its balance point is similar, though it’s a slightly less aggressive bike thanks to the smaller wheel sizes. 

However, while less aggressive, those smaller wheels also mean more tire variety, making it a good option for cyclists who want selection or looking for something other than standard mountain bike tires for their new ride. 

The fork on the Giant ATX 2 also has slightly less travel room, making for a bumpier ride. 

Overall, we’d say that the Marlin 4 is a bike that will do just a little more than the Giant ATX 2, including that it will match your skill better longer. However, the Giant ATX 2 may be the better bike for beginners who don’t want an aggressive design on day one. 

The Trek Marlin 4 might not be a bike you want to take to a championship race or marathon, but it’s not supposed to be that kind of bike. It’s designed to be a good starter option and a functional mountain bike for riders on a budget. The design is simple, as are the features, but effective. 

Overall, this is a good option for a starter bike, an intermediate bike, or a bike for family members who aren’t all that sure of mountain biking yet.

Its race-inspired design in addition to its mid-quality components makes the Trek Marlin 7 the perfect bike for the average to advanced rider looking for a sturdy bike that is packed with tons of tailored features to fit their busy lifestyle.

Take a look below to find all of the critical specifications and details about the Trek Marlin 7 that can translate into real-world performance enhancements for all of your future rides. 

Front/Rear Derailleur 

The Marlin 7 comes outfitted with a Shimano Altus M2020 2-speed front derailleur and a Shimano Acera M3000 9-speed rear derailleur. Both components work together seamlessly to deliver smooth gear transitions that allow you to adapt your riding style in a wide range of terrains.

Their durable build quality enhances their functionality to provide you with consistent reliability with every pedal. 

Brakes 

The Marlin 7 also has MT200 Shimano hydraulic disc brakes, which deliver almost instant stopping power regardless of the terrain. These brakes perform great for providing immediate braking action when faced with high-speed docents and all sorts of other intense situations.

When you look at the brakes on this bike compared to its tire and wheelset, it’s the ability to stop in wet climates in unmatched in bikes of a similar class. 

Rims/Tires 

For the tires and rims, the Marlin 7 is packing Bontrager aluminum connection double-wall wheels and Bontrager XR2 Comp tires.

This combination provides real ride support in various conditions while also aiding the brakes in delivering an immense amount of stopping power that will impress any rider. While the wheels on the Marlin 7 are not tubeless-ready, you can convert them into a tubeless setup. 

Frame 

marlin 7 frame

The Trek Marlin 7 has an Alpha Silver Aluminum frame that is ultra-lightweight and very durable. The Marlin 7 frame uses race-ready frame geometry to deliver actualized performance benefits when taking on demanding tasks such as serious singletrack aspirations or high-speed downhill attacks. The head tube angle on this bike is 69.5-degrees, and it has a 73-degree seat tube angle that puts in an optimal position for maximum handling control in all situations. 

The agile yet stable performance of the Alpha Silver Aluminum frame on this bike definitely makes it one of the leading choices for mid-range trail bikes. 

The fork on the Marlin 7 is a RockShox XC 30 adjustable fork that delivers enhanced performance upgrades that add 100mm of travel underneath your hands. In addition to this, it also comes with a preload function that makes it easy for you to adjust your ride before hitting the trails.

You’ll also find a turnkey lockout feature, which makes it easy for you to lock it in place with the simple switch of a button even while riding. This fork is optimal for rough terrains, technical trail rides, and fast descents. 

trek marlin 4 bike review

The Trek Marlin 7 comes outfitted with an efficient and lightweight 2×9 drivetrain that is built using a 36/22t crankset in addition to an 11-36T cassette.

These features combine to deliver broad gear range while also reducing the amount of time it takes to transition from one gear setting to another. It’s fast, high-performing, and built to last, enhancing the overall value of the Marlin 7. 

These are all of the main features that come packed into the Trek Marlin 7, after taking a look at them, you can probably see why it’s one of the best mid-range bikes currently available.
