Overview
The Trek Fuel+ EX 9.8 XT Di2 Gen 2 is a capable mountain e-bike built for trail riding, offering a strong motor with smooth support and confident braking that makes it reliable on rough terrain. Its carbon frame and suspension system provide a comfortable ride over uneven surfaces, though the battery capacity and range are modest, which may require more frequent charging on longer rides. The non-removable battery means you'll need to keep the whole bike near a power source when charging, and while it's a high-performing machine, its price point may feel steep compared to similar models.
Best For
✓
This mountain e-bike should suit riders who prioritize performance on trails and rough terrain, with a focus on control, comfort and confidence. Its high power-to-weight ratio and hydraulic disc brakes make it well-suited for technical off-road riding, while the front and rear suspension should enhance comfort on uneven surfaces. Riders who value a responsive and natural riding experience, especially on more challenging trails, are likely to appreciate its capabilities.
Who Should Avoid It

Where to buy
Priced at £8,075, the Trek Fuel+ EX 9.8 XT Di2 Gen 2 sits towards the higher end of the mountain bike market for 2026 models. Its premium components and advanced features justify the cost, though buyers may want to consider whether the investment aligns with their specific needs and usage.
Compared with similar mountain bike e-bikes on Bikkerr, this model sits £2,416.93 above average
The Trek Fuel+ EX 9.8 XT Di2 Gen 2 is listed at £8,075, which places it at the higher end of the price spectrum when compared to similar mountain e-bikes from the same year. It offers strong motor output for this type of e-bike, with a power-to-weight ratio that feels favourable, and features like hydraulic braking and front and rear suspension that enhance control and comfort on rough terrain. However, some similar e-bikes may offer a larger battery or more range, and a non-removable battery could limit charging flexibility for certain riders. For a mountain e-bike, the trade-off between a more modest battery and the performance benefits of a lightweight carbon frame may be more relevant to riders prioritising agility and trail responsiveness over extended range. Buyers who value strong motor support, precise handling and a responsive ride on technical trails are more likely to see the value in this package, though those needing longer range or easier battery access might find alternatives more suitable.

This mountain e-bike offers a strong motor output for its category, with a power-to-weight balance that should make the assistance feel lively and responsive on trails. Next to similar models, its torque is more modest, which may mean steeper climbs require a bit more rider effort, but the torque sensor should keep the assistance feeling natural and proportional to pedaling input. The motor support should help with technical riding and rough terrain, though some alternatives may offer stronger low-speed or climbing assistance. The sensor type and power delivery should give riders good control over assistance levels, making it adaptable for different trail conditions. Riders looking for a responsive motor that feels balanced on trails, with a focus on agility rather than maximum climbing power, may find this setup well-suited to their needs.
This explanation is based on the bike’s motor power, torque, battery capacity, claimed range, charging
time, sensor type and how those figures compare with similar e-bikes in our database.
eBike FAQs
Is this bike suitable for long off-road rides?
This mountain e-bike is well-suited for off-road trails, with a strong motor and confident braking that should handle rough terrain effectively. However, its battery capacity and range are below average, so longer rides may require more frequent charging. The non-removable battery also means you'll need to keep the whole bike near a power source when charging.
How does the motor perform on steep climbs?
The motor should provide strong support on steep climbs, thanks to its 600W power and 60Nm of torque, which should help you tackle challenging terrain with confidence. However, the battery capacity is below average, so you may need to plan for more frequent charging on longer or more intense climbs. The non-removable battery also means you'll need to keep the bike near a power source when charging.
Does the bike offer good comfort on rough trails?
The Trek Fuel+ EX 9.8 XT Di2 Gen 2 should offer decent comfort on rough trails thanks to its front and rear suspension, which should help absorb shocks and improve ride quality over uneven terrain. However, the battery capacity is below average, so you may need to plan charging stops more carefully if you're riding for extended periods on rough trails.
Is the battery capacity sufficient for extended trail use?
The battery capacity of 580 watt-hours is below average for a mountain e-bike, which means you may need to plan for more frequent charging during extended trail use. While the motor provides strong support for climbing and trail control, the battery range of 50 miles may not be sufficient for very long rides without additional charging options. The non-removable battery also means you'll need to keep the bike near a power source when charging, which could be a consideration for multi-day trips or remote trail use.
How practical is this bike for daily use and charging?
This bike is well-suited for daily trail use, with a strong motor and confident braking that handle rough terrain effectively. However, the non-removable battery means you'll need to keep the whole bike near a power source when charging, which can be less convenient. With a range of 50 miles, it should handle most daily rides, but longer trips may require careful planning due to the battery's modest capacity.
Who is this bike best suited for?
This bike is best suited for experienced trail riders who prioritize performance and braking confidence over range and battery capacity. Its powerful motor and hydraulic disc brakes make it reliable on rough terrain, and the suspension system ensures comfort on uneven surfaces. However, the non-removable battery and modest range may require more frequent charging, making it less ideal for riders who need extended use without access to power sources.
Is this bike good value compared with similar e-bikes?
This bike is a high-performing mountain e-bike with a strong motor and confident braking, but its price may feel steep compared to similar models. While it offers a good power-to-weight ratio and comfortable suspension for off-road trails, the battery capacity and range are below average, which could mean more frequent charging on longer rides. These factors, along with the non-removable battery, may make it less practical for some buyers looking for a more balanced value proposition.
What are the main compromises of this bike?
The main compromises of this bike include its limited battery capacity and range, which may require more frequent charging on longer rides. The non-removable battery also means you'll need to keep the whole bike near a power source when charging. While it offers strong motor power and confident braking, the price point may feel high compared to similar models, and the battery efficiency is average for this type of e-bike.
