Overview
The 2026 Trek Fuel+ EX Gen 2 is Trek’s lightweight electric trail bike, designed to feel as close to an analog bike as possible while providing meaningful motor assistance. Built around the TQ HPR60 motor (60Nm torque, 350W peak, just 1.92kg) and a 580Wh battery, the Fuel+ EX delivers the trail-riding experience of the analog Fuel EX with the added benefit of motor-assisted climbs. With 150mm of front travel and 145mm of rear travel on 29″ wheels, it sits squarely in the trail eMTB category.

The Fuel+ EX Gen 2 features an adjustable head angle of 64.5° with the option to tune ±1° using angle-adjust headset cups. Five frame sizes (S through XXL) ensure a wide fit range, with reach spanning from 430mm (S) to 530mm (XXL). Size-specific chainstays grow from 437mm on S/M to 452mm on XXL, maintaining proportional handling across the range. The geometry closely mirrors the analog Fuel EX Gen 7, reinforcing Trek’s goal of making the Fuel+ feel like its unpowered sibling.

Geometry Analysis
The Fuel+ EX’s geometry is remarkably close to its analog sibling, the Fuel EX Gen 7 — and that’s entirely by design. The 64.5° head angle is modern and confidence-inspiring without being enduro-slack, striking the ideal balance for trail riding where climbs and descents are equally important. The effective seat tube angle ranges from 78.6° (S) to 76.4° (XXL), getting progressively slacker on larger frames to maintain a centered riding position. Reach figures are generous across the range, with 460mm on M and 485mm on L providing a roomy cockpit. The size-specific chainstays (437-452mm) are slightly longer than the analog Fuel EX to accommodate the TQ motor, but the difference is minimal enough that handling characteristics remain remarkably similar.
Ride Characteristics
The Fuel+ EX Gen 2 is the eMTB that feels most like a regular bike. The TQ HPR60 motor is so light and compact that when you’re descending with the motor off, you could almost forget it’s an eMTB — the weight distribution, suspension feel, and handling are all remarkably close to the analog Fuel EX. On climbs, the 60Nm of torque is sufficient for most trail riding, though it lacks the raw grunt of a Bosch CX system on steep, technical ascents. The 580Wh battery provides adequate range for 2-3 hour rides, though heavy use of Turbo mode will drain it faster. On descents, the 150mm fork and 145mm rear travel handle rough terrain with composure, and the lower eMTB weight (compared to full-power bikes) means the bike remains playful and responsive. This is the eMTB for riders who value the feel of riding over maximum motor assistance.

What’s New vs Previous Generation
The Gen 2 Fuel+ EX carries forward the TQ HPR60 motor system introduced with the Gen 1, but with a redesigned frame that more closely aligns geometry and kinematics with the analog Fuel EX Gen 7. The frame has been refined for better weight distribution, improved cable routing, and updated internal storage. The 580Wh battery remains, and the motor firmware has been updated for smoother power delivery and improved battery management. The addition of a XXL size extends the fit range compared to Gen 1.
Who Should Consider This Bike
The Fuel+ EX is ideal for riders who want motor assistance but refuse to give up the feel of a real trail bike. If you value light weight, natural handling, and the ability to ride with the motor off without feeling like you’re dragging an anchor, the Fuel+ EX delivers. It’s perfect for riders who want to extend their range, ride with faster friends, or simply enjoy more time on the trail without the fatigue of an all-analog ride. Riders who need maximum power and range for big mountain days should consider the Rail+ instead. Those who want a more gravity-focused eMTB should look at the Slash+.
Comparable Models
The Fuel+ EX competes with the Specialized Turbo Levo SL, Giant Trance X E+, Orbea Rise, Canyon Neuron:ONfly, and Santa Cruz Heckler SL. The Fuel+ EX and Levo SL are the closest competitors — both use lightweight motor systems to create eMTBs that feel like analog bikes. The Orbea Rise pioneered this lightweight eMTB category. The Giant Trance X E+ uses a full-power Yamaha motor for a different riding experience. The Fuel+ EX’s TQ HPR60 motor is one of the lightest and most compact in the category, contributing to its natural riding feel.

Frequently Asked Questions
What motor does the 2026 Trek Fuel+ EX use?
The Fuel+ EX Gen 2 uses the TQ HPR60 motor, producing 60Nm of torque and 350W peak power while weighing just 1.92kg. It’s one of the lightest eMTB motor systems available.
How much does the Trek Fuel+ EX weigh?
The Fuel+ EX weighs approximately 37-40 lbs (17-18 kg) depending on build and size. This is significantly lighter than full-power eMTBs like the Rail+ (50+ lbs) and closer to analog bike territory.
What is the battery range of the Trek Fuel+ EX?
With the 580Wh battery, expect 2-4 hours of riding depending on assist level, terrain, and rider weight. Eco mode provides the longest range, while Turbo mode will drain the battery significantly faster.
Is the Trek Fuel+ EX the same as the Trek Fuel EX?
No. The Fuel+ EX is the electric version with a TQ HPR60 motor and 580Wh battery. The Fuel EX Gen 7 is the analog (non-electric) version. They share very similar geometry and suspension design, but the Fuel+ EX is heavier due to the motor and battery.
Does the Trek Fuel+ EX have adjustable geometry?
Yes. The Fuel+ EX comes with a 64.5° head angle in the standard configuration. Aftermarket angle-adjust headset cups allow ±1.0° of adjustment, giving three possible positions: 63.5°, 64.5°, or 65.5°.
