Trek Fuel+ Buyer Guide UK (2026) | EX vs MX vs LX Comparison
Understanding the difference between Fuel+ EX, MX and LX — and choosing the setup that matches how and where you ride.
The Trek Fuel+ is designed for riders who want an electric mountain bike that still feels like a proper trail bike. Instead of chasing huge power numbers, Trek paired the Fuel+ platform with the TQ HPR60 drive system — a compact, quiet motor that delivers smooth assistance while keeping the bike feeling light and natural on the trail. All Fuel+ bikes use the same motor and battery system. What really changes between models is the EX, MX and LX configurations, which adjust suspension travel, wheel setup and overall ride character.

Choosing the right Fuel+ isn’t about power — it’s about how you want the bike to ride.
Fuel+ EX vs MX vs LX
Every Fuel+ bike uses the TQ HPR60 motor, producing 60Nm of torque and up to 350W peak power. The motor weighs roughly 1.9kg and is paired with a 580Wh integrated battery, creating a system that feels noticeably quieter and lighter than many full-power e-MTB setups.
Where the bikes really differ is in how they ride. The EX is the balanced trail bike. The MX is the playful mullet setup. The LX is the longest-travel option designed for rougher terrain.
Fuel+ EX
Best for: Riders who want the most balanced and versatile trail setup.
Ride feel: The EX feels neutral and predictable on the trail. It climbs efficiently, descends confidently and works well across a wide range of terrain.
Fuel+ MX
Best for: Riders who want a more playful bike.
Ride feel: The MX uses a mullet wheel setup which makes the bike feel more agile through tighter trails and easier to move around underneath you.
Fuel+ LX
Best for: Riders who prioritise descending confidence and rougher trails.
Ride feel: The LX is the most planted setup in the range, with extra suspension travel designed for faster and more demanding terrain.

Start With How You Ride
Most riders choose their Fuel+ based on the type of terrain they ride most often.
Start by thinking about how you want the bike to feel on the trail.
Do you want a versatile trail bike that climbs well and handles a bit of everything?
If your riding includes a mixture of climbs, trail centres and natural singletrack, a balanced trail bike usually makes the most sense.
You want a bike that climbs well, descends confidently and feels comfortable on a wide range of trails.
→ Start with the Fuel+ EX, which runs 145mm rear travel and 150mm front travel with a full-29 wheel setup.On Small frame sizes, Trek uses a 27.5" rear wheel (mullet setup) to maintain better rider fit and handling.
Do you prefer a more playful bike?
Some riders prefer a bike that feels easier to move around underneath them.
A mullet setup can make a bike feel more agile through tighter sections of trail.
→ The Fuel+ MX uses 150mm rear travel and 160mm front travel with a 29" front wheel and 27.5" rear wheel.
Do your rides include rougher or steeper terrain?
If descending performance is your priority, a longer-travel setup will provide more stability and control.
More suspension travel can also help the bike stay composed when trails get rough.
→ The Fuel+ LX offers up to 160mm rear travel and 170mm front travel, giving it the most capability on demanding trails.

Fuel+ motor and battery system
The defining feature of the Fuel+ platform is the TQ HPR60 drive system.
The system is designed to deliver smooth, quiet assistance while keeping the ride feel close to a traditional mountain bike.
TQ HPR60 motor
The HPR60 motor produces 60Nm of torque and up to 350W peak power, while weighing roughly 1.9kg. Its compact design allows Trek to maintain natural frame geometry and handling.
580Wh battery and range extender
Fuel+ bikes use a 580Wh integrated battery inside the frame. For longer rides, the system also supports a 160Wh range extender, increasing total battery capacity to 740Wh.
Expected range
Range depends on rider weight, terrain, elevation and assist mode, so exact distances will vary. As a rough guide, many riders can expect around 30–50 miles (50–80km) of mixed trail riding from the 580Wh battery. Adding the optional range extender can significantly increase total ride distance on bigger days out.

Frequently Asked Questions
How heavy is a Trek Fuel+?
Fuel+ bikes typically weigh around 20–21.5kg depending on model and specification, with higher-end builds usually sitting at the lighter end of that range.
Do Trek Fuel+ bikes come tubeless?
Yes. They come set up tubeless out of the box, and we supply the bike fully built and ready to ride.
What warranty comes with the bike and motor?
Trek frames are covered by Trek’s lifetime frame warranty for the original owner, and the TQ motor and battery system normally carries a 2-year manufacturer warranty. If anything ever needs attention, we handle the support process with Trek and TQ for you.
How do I see ride stats or adjust motor settings?
Fuel+ bikes work with the Trek Central app, which allows you to view ride data, battery information and system diagnostics. You can also connect the bike to most Bluetooth or ANT+ cycling computers.
Can I change wheel sizes on a Fuel+?
Yes, but it requires the correct hardware. Fuel+ frames are designed around a 29" front wheel, and changing the rear wheel configuration requires the appropriate rocker link and lower shock mount so the bike’s geometry stays correct.
