Overview
The Trek Fuel+ EX 9.8 Eagle 90 Gen 2 is a capable mountain bike designed for trail riding and rough terrain, offering a responsive feel with its powerful motor and suspension system. Its carbon frame and hydraulic disc brakes provide confidence on challenging trails, while the front and rear suspension ensures a comfortable ride over uneven surfaces. However, the battery is not removable, which means charging requires the bike to be near a power source, and the range is modest, requiring careful planning for longer rides. Despite its high price, the bike delivers strong performance for its intended use, though it may not be the most practical choice for daily commuting or extended trips.

Where to buy
Priced at £7,625, the Trek Fuel+ EX 9.8 Eagle 90 Gen 2 sits towards the higher end of the mountain bike market for 2026 models. Its premium components and performance capabilities justify the cost, though buyers may want to consider whether the price aligns with their specific needs and budget.
Compared with similar mountain bike e-bikes on Bikkerr, this model sits £1,966.93 above average
The Trek Fuel+ EX 9.8 Eagle 90 Gen 2 is listed at £7,625, which is on the higher side when compared to similar mountain e-bikes from the same year. It offers strong motor output and a well-balanced power-to-weight ratio, which is a key strength for this type of bike, along with hydraulic disc brakes and front and rear suspension that support control and comfort on rough terrain. However, some similar e-bikes may offer a larger battery or more range, and others might provide stronger climbing support, which could be important for more demanding off-road use. For a mountain e-bike, the trade-off here seems to be between a lighter, more agile frame and a slightly more modest battery capacity, which may affect range. Riders who prioritise agility, responsiveness and a high-quality riding experience on technical trails may find the value more compelling, while those needing extended range or easier battery access might look elsewhere.

TQ-HPR 60
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 provide a smooth, controllable ride, especially when adjusting effort through different trail conditions. Riders looking for a responsive trail e-bike with balanced power and a lighter feel may find this motor 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 bike is well-suited for off-road trails, with a powerful motor and suspension system that should handle rough terrain effectively. However, the battery is not removable, which means you'll need to charge it near a power source, and the range of 50 miles may require careful planning for longer rides. If you're looking for a bike that excels on trails but need to manage charging and range, this could still be a good fit for your off-road adventures.
How does the motor perform when climbing steep trails?
The motor should provide strong support when climbing steep trails, thanks to its 600W power and high power-to-weight ratio, which helps maintain momentum on inclines. However, the motor's torque is on the lower side for this type of e-bike, so you may need to manage your speed and effort carefully on very steep or technical sections. The bike's overall performance should be adequate for most trail climbs, but longer or more intense rides may require planning for battery range and charging.
Does the bike's suspension system handle rough terrain well?
The Trek Fuel+ EX 9.8 Eagle 90 Gen 2 features front and rear suspension that should significantly improve comfort on rough terrain, making it well-suited for trail riding and uneven surfaces. The suspension system is designed to absorb shocks and provide a smoother ride over rocky or uneven ground, which is typical for mountain e-bikes. However, the battery is not removable, so charging requires the bike to be near a power source, which may be a consideration for multi-day adventures.
Is the battery capacity sufficient for multi-day trail adventures?
The battery capacity of 580 watt-hours is below average for mountain e-bikes, which means you'll need to plan carefully for multi-day trail adventures. With a range of around 50 miles per charge, you may need to carry spare batteries or have access to charging points along your route. Since the battery isn't removable, charging the bike requires it to be near a power source, which could be inconvenient during extended trips.
How easy is it to charge the battery, and how long does it take?
The battery is not removable, so you'll need to charge the bike near a power source, which may be less convenient for some riders. Charging time is average for a mountain e-bike of this type, but the battery capacity is below average, so you may need to plan your rides carefully to avoid running out of power mid-trip.
Is this bike a good value option compared to similar mountain e-bikes?
This bike offers strong performance for off-road use, with a powerful motor and confident braking, but its value depends on your priorities. The high price and below-average range may make it less practical for longer rides or frequent use. If you're focused on trail performance and don't need extended range or easy charging, it could be a solid choice, but there are more affordable options with better battery efficiency and charging convenience.
Who would this bike be best suited for?
This bike is best suited for experienced trail riders who prioritize performance and control on challenging off-road terrain. Its powerful motor and hydraulic disc brakes make it a strong choice for technical trails, while the suspension system enhances comfort over rough surfaces. However, the non-removable battery and modest range may make it less practical for multi-day adventures or riders who need frequent charging on the go.
What are the main limitations or trade-offs of this bike?
This bike offers strong performance for off-road trails, but there are a few trade-offs to consider. The battery is not removable, so charging requires the bike to be near a power source, which may be inconvenient for some riders. Additionally, the range is below average, meaning you'll need to plan carefully for longer rides or carry spare batteries. While the motor is powerful, the battery capacity is also below average, which could limit your options for extended trail adventures.
