Trek FX 3 Disc Review: All You Need to Know

If you’re after a bike that can handle your commute and take you on adventures at the weekend, then look no further – our Trek FX 3 Disc review is what you’re looking for.

Not everyone who looks for a mountain bike wants to go for tough dirt trails. Many people are looking to make a swap from driving to cycling when it comes to their daily commute – both for environmental and health reasons. Cycling for fitness is always a good idea, and there are plenty of gentler trails or cycle paths to explore.

The question is – does the FX 3 Disc tick all those boxes?

The Bottom Line:

[September,2022 UPDATE: The Trek FX 3 20-21 version has been discontinued, but in its place, Trek has released the 2023 FX 3 Disc. This bike is nearly identical to its previous iteration but with an upgraded drive train and 10 speeds instead of 9. 

You can’t go wrong with this newer version; you’ll get everything you love about the Trek FX 3 in an upgraded and sleek package]

How does Trek compare to other companies?

Trek was founded in 1976. They’re well-known for their work with Lance Armstrong in the late ’90s, and they have a good reputation in terms of designing and manufacturing excellent bikes. They were the first company to pay women the same amount as men for racing at a World Cup level.

They’re also starting to offer a range of eco-friendly products, designing bikes for those on a low budget to encourage cycling over driving. Overall, they’re a good company with a great track record.

They’re known for their generous lifetime warranties on frames and 2-year warranties on parts – which we’ll go into in more detail a little later.

Trek offers bikes across a huge price range – from around $450-$500 dollars, right through to $12,000 or more. That covers all skill levels – from beginner to pro – and they also make bikes for kids.

Trek offers a big range, so they’re not as specialized as, say, Evil (who produces a small range of bikes suited for tougher trails, like Evil the Wreckoning). They’re quite close in terms of quality and price to Santa Cruz and Giant (you can read more about how Trek compares to Giant in our brand comparison here).

You could also compare them to Diamondback in terms of quality, although Diamondback doesn’t offer as many entry-level options as Trek.

What kind of bike is the Trek FX 3 Disc?

The FX 3 Disc is a hybrid bike, designed to be used on your commute, on pavements, or on rail trail. It’s super-lightweight, which makes it ideal for public transport. It’s ideal if you want to get fit and get places quickly at the same time.

It has an entry-level price point. There are cheaper bikes out there, of course, but this strikes a nice balance between quality materials and a low price. It’s designed to be easy to use, with great brakes that work really well on pavements, even if it’s pouring with rain.

It’s a really simple-looking bike. If you want a bike that looks distinctive, or you’re after a ‘status symbol’ bike, this won’t be the one for you. If you want something that looks simple and sleek and functions well, it’s a good choice.

The main features of the Trek FX 3 Disc

Now, we’ll look at the FX 3 Disc in more detail.

What is it made from?

  • The frame is made from aluminum, which helps to keep it light. The whole bike weighs 11.74kg (or 25.88lbs) – that’s for the medium size.
  • There are five sizes to choose from, from S through to 2XL.
  • It comes in two colors – Dnister Black or Rage Red.

What are the wheels like?

The wheels consist of Bontrager Tubeless Ready Disc 32-hole rims, and Bontrager H2 Hard-Case Lite tires.

The tires are designed to work really well on pavements (even in slippery, rainy weather). They’re tough and puncture-resistant, so if you were to accidentally ride over something sharp, you won’t have to worry about dealing with a flat on your way to work.

What other features does it have?

The great thing about the FX 3 Disc is that it has a few extra touches that make it very convenient to use. It has ‘Blendr Stem’ technology – this is a system involving a stem, base, and mount, meaning you can easily install accessories onto your bike. Whether you want to attach lights, a GoPro, or a Satnav, they’ll be secured safely to the frame. You can also attach a water bottle mount and mudguards.

It also integrates a Bluetooth/ANT+ sensor. This allows you to track fitness routes with your computer or smartphone, with no external sensor required.

The frame looks sleek because it has the cables routed internally, which is a nice touch.

It also comes with built-in mounts, meaning you can easily add racks and fenders.

How does it perform?

It’s a very smooth ride on pavements, but it also performs well on gravel and grass.

The excellent brakes mean that users feel safe even if the pavements are uneven or slick with rain – even going downhill at a faster speed, the brakes work really well.

You can go pretty fast with the FX 3 Disc – it compares really well with a specialized road bike in that regard – but you can transition onto other types of terrain, too.

It doesn’t do well on very uneven surfaces – you won’t be able to hit the trail with this bike, as the suspension isn’t designed to deal with big dips or bumps. However, you should be able to deal with slightly bumpy terrain (like gravel or dirt paths) with no problems.

It’s designed to be easy to ride. You don’t have to be an expert with hours of practice to use the FX 3 Disc – perfect for those who want to make a swap for their commute, or those wanting to take up bike riding for exercise.

What are the specifications?

Here are the main specs for the FX 3 Disc:

  • Fork – FX Carbon, rack and fender mounts – flat mount disc
  • Crankset – Shimano MT210 46/30, chainguard, 170mm length (size S,M)/Shimano MT210, 46/30, chainguard, 175mm length (size L, XL, XXL)
  • DerailleursShimano Acera T3000, 34.9mm clamp (front)/Shimano Acera M3000, shadow design, long case (rear)
  • Brakes Shimano MT201 hydraulic disc, flat mount, 160mm rotor
  • SaddleBontrager H1

What is the warranty?

As we mentioned earlier, Trek offers a lifetime warranty against defects in materials or workmanship. The lifetime warranty covers the frameset, main frame, and full suspension swing arms, as well as Bontrager wheels with carbon rims.

Then there’s a 2-year warranty on apparel, parts and accessories, rear suspension linkage components, Bontrager wheels with alloy rims, and paint and decals.

Subsequent owners are entitled to a three-year warranty from the date of purchase from the retailer.

For an extra cost, they offer Trek Carbon Care, to obtain discounts on replacement frames or components in the case of damages that don’t fall under the warranty conditions.

What is the price range for the FX 3 Disc?

The price range is around $800. This makes it a pretty good entry-level bike. There are some things available at an extra cost – like the Duo Trap S, a sensor that enables pairing with your smartphone or computer.

The FX 3 Disc is suited for:

  • Workers wanting to lower their carbon footprint by switching from driving to cycling for their commute
  • People wanting a lightweight bike – for example, those that can’t carry a heavy bike, or those that foresee themselves transporting it often
  • People wanting to cycle for fitness purposes
  • Those wanting a bike that can deal with ‘fun’ rides at the weekend as well as commuting on pavements

The FX 3 Disc is not suited for :

  • Those wanting a hard-wearing bike that can handle tough trails
  • Those wanting a unique-looking bike – it looks nice, but it’s not distinctive in design

What do users think of the FX 3 Disc?

Users have great things to say about the FX 3 Disc. Those using it for commuting really enjoy how safe it feels, particularly when going downhill or traveling on rainy days. They find it to be a great bike for shopping or just cycling around town.

Other users enjoy it for exercise purposes. The Bluetooth functionality provided by the additional Duo Trap S sensor is a popular feature, with users finding it helpful to see the data after a long bike ride.

Most users were impressed with how well the bike switches between different types of terrain – it can handle mild bike trails, grass, gravel, and pavements equally well. Some people found the ride provided by the FX 3 Disc to be so smooth that they’ve decided to cycle more than drive – which is great!

The only drawbacks seem to be the seat, which some people decided to swap out for something a little more comfortable, and the fact that it doesn’t have a kickstand, which would be more convenient.

Some users found that the paint chipped and scratched a little when riding on gravel. You might find this is the case for a lot of bikes, but it’s still worth mentioning that the paint isn’t that resistant to scratches or marks.

The Pros and Cons of the Trek FX 3 Disc

Now let’s take a look at the good and bad points of the FX 3 Disc.


  • Really versatile – fun to ride in lots of different situations
  • Smooth to ride – great for swapping out driving for cycling
  • The brakes are really strong even downhill or on slippery surfaces
  • Decent price point
  • A clean, simple frame


  • The seat isn’t comfortable enough for some people
  • It doesn’t have a kickstand
  • The paint may get scratched if riding on gravel

FX 3 Disc Alternatives

There are a few bikes to look at that are similar to the FX 3 Disc:

Dual Sport 1 Gen 4

The Dual Sport Gen 4 is a great deal cheaper than the FX 3 Disc, but it packs all of the essentials into a stylish package. You can go from the sidewalk to a dirt trail without a second thought.

It’s perfect for the hybrid bike lover who needs a reliable bike for work and play but don’t want to spend over a thousand. 

Check out the Dual Sport 2 and 3, slightly more expensive but with some worthwhile upgrades that will allow you to enjoy your adventures just a little bit more. 

Marlin 8 Gen 2

The Marlin 8 is a mid-range mountain bike with a lot of options. While it’s an overall simple bike, it’s perfect for both a daily commute and an adventure in rougher terrain.

It is a little bit more expensive and heavier than the FX 3, but it looks like it would be able to handle rougher terrain at a smoother pace. A more enjoyable adventure is often worth a little extra cash. 

Haanjo 2

The Haanjo 2 from Diamondback is another budget mountain bike that’s great for both on-road and off-road adventures. It’s sturdy and capable of handling most things you throw at it.

It’s great for someone who just needs a good reliable entry-level bike or someone who doesn’t want to spend 1000s of dollars just to enjoy one of their favorite hobbies.

I will say the overall style of the bike feels like it’s geared towards a younger audience. 

Trek Marlin

The Trek Marlin 5 is a great hybrid bike – it’s a good-quality bike aimed at beginners as well as more advanced riders, and it’s perfect for mild trails as well as the commute.   

There’s also the Trek Marlin 6, a more updated version of the Marlin 5, which is a great, sturdy bike, also versatile and great for beginners.   

Diamond Overdrive

If you want something that can handle some tougher trails as well as smoother terrains, you could try the Diamondback Overdrive – it’s not as commute-friendly, but good for those wanting to get into cycling for exercise.

Answer: It has a maximum total weight of 300lbs.

Answer: Yes – there’s the FX1 Disc and the FX2 Disc, which are slightly older and cost a bit less than the FX 3 Disc.

The Final Verdict – is the Trek FX 3 Disc Really Worth It?

We definitely think so!

The Trek FX 3 Disc isn’t a perfect bike. You may need to make some swaps (for example, the saddle). You might find the extras you want, like the Blendr System technology to attach lights or smart devices, or the Bluetooth sensor for fitness tracking, bumps the price up quite a bit. It’s also not the cheapest bike out there – there are definitely lower-priced options available.

However, we still think it’s a great bike for beginners, and it’s worth spending extra for. The materials are good-quality, but still lightweight. We like the fact that there are fenders and mounts already installed, and the fact that the cabling runs through the frame makes it look sleek.

Trek FX 3 Disc

It’s a comfortable ride on most terrains, and we really like the fact that it’s safe – having good-quality brakes that can handle hills and slippery surfaces is really important for all bikes, but especially those commuting in high-traffic areas. 

We would recommend this bike for anyone, but particularly for beginners – it might just give you the cycling bug.

1 thought on “Trek FX 3 Disc Review: All You Need to Know”

  1. I bought a Trek FX 3 last year as a commuter bike and have to say it’s been great. My commute is pretty flat so I mostly stay in the big ring and the middle of the cassette (gears 4 to 7), so it’s a smooth and easy ride. On the few occasions I’ve encountered hills I’ve gone up them without having to strain.

    I opted to swap the stock tyres for Schwalbe Marathons because I’ve had good experience with those before; maybe an unnecessary upgrade but London roads can be a minefield of broken glass and debris, so I appreciated the extra confidence. Additionally, I added Bontrager mudguards, a Topeak rack to clip my panniers to and a kickstand. Definitely good investments!

    The saddle is fine for me for the time it takes to get the office (about an hour), but I can imagine on longer rides it might start to feel hard.

    My only complaint, which you mention in the review, is that the paint chips easily. I’ve not ridden it much on gravel – a couple of times, for less than a mile – and the down tube has several noticeable chips.

    As I say, it’s a great bike and thoroughly recommended. But be aware that the new 2022 model has a different drivetrain, replacing the 2×9 set-up with 1×10.
