Overview
The Trek Fuel EXe 9.8 is a capable mountain e-bike built for trail riding, offering smooth motor support and confident braking that makes it feel stable on rough terrain. Its efficient battery provides a reasonable range for most rides, though longer trips may require careful planning. The bike’s lightweight carbon frame and torque-sensing motor deliver a natural riding feel, but its lower motor power and torque mean it won’t dominate steep climbs or high-speed acceleration. While the price reflects its premium build, it may not be the most budget-friendly option for those prioritizing range or power.

Who Should Avoid It
×
Riders who frequently tackle steep hills or need extended range on long off-road rides may want to compare alternatives. The motor power and torque are below average for similar mountain e-bikes, which could make climbing challenging, and the battery capacity is also lower than average, limiting range. Additionally, the non-removable battery may be inconvenient for riders who need to charge quickly without moving the whole bike. However, the bike still offers strong braking, smooth power delivery, and good off-road capability for riders prioritizing these features.

The Trek Fuel EXe 9.8 is listed at £8,250, which sits at the higher end of the price spectrum when compared with similar mountain e-bikes from 2025. It offers strong points like efficient battery use, hydraulic disc brakes for confident stopping, and front and rear suspension that should help with control on rougher trails. However, some similar e-bikes may provide a larger battery, more range, or stronger motor support for climbing, 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 slightly reduced battery capacity and motor output, which may appeal more to riders who prioritise handling and responsiveness over maximum range. Buyers looking for a lightweight, agile mountain e-bike with good trail control may find the value more compelling, while those needing extended range or stronger hill support might find the price harder to justify.

TQ-HPR 50
This mountain e-bike offers a more modest motor output for its category, with assistance that should feel natural and proportional to rider effort thanks to the torque sensor. Next to similar trail e-bikes, it may not deliver the same level of outright punch or aggressive low-speed support, but its balanced power-to-weight ratio and efficient motor system should make it feel agile and responsive on technical terrain. Climbing steeper trails may require more rider input, especially when loaded, and the motor’s support may feel less forceful than some alternatives. The torque-sensing system should help maintain smooth and predictable power delivery, though riders seeking stronger motor punch or extended range on longer rides may find some trade-offs. This motor setup is likely to suit riders who prioritize agility, efficiency and trail control over maximum climbing power or long-distance range.
This explanation is based on the bike’s motor power, torque, battery capacity, claimed range, charging

eBike FAQs
Is this bike suitable for long off-road rides?
The Trek Fuel EXe 9.8 is well-suited for off-road trails, with hydraulic disc brakes that provide confident stopping power and a lightweight frame that handles rough terrain comfortably. However, its lower motor power and torque may make steep climbs or long rides more challenging, and the battery range of 50 miles means you’ll need to plan for charging stops on multi-day adventures. This bike is a solid choice for trail riding but may not be the best for extremely demanding off-road conditions or extended rides without access to charging.
How does the motor perform when climbing steep trails?
The motor provides smooth support for climbing trails, but its lower power and torque may make steep climbs feel less effortless, especially on longer or more technical ascents. While it should handle moderate inclines with confidence, riders looking for strong acceleration or heavy-duty hill climbing might find this bike less powerful compared to others in its category.
Does the bike have enough battery range for multi-day adventures?
The Trek Fuel EXe 9.8 has a battery range of 50 miles, which is below average for mountain e-bikes. This means that for multi-day adventures, you may need to plan carefully, such as carrying spare batteries or finding charging points along the way. The battery is not removable, so charging requires the whole bike to be near a power source, which could be inconvenient on extended trips.
How easy is it to charge the battery, and is it removable?
The battery on the Trek Fuel EXe 9.8 is not removable, so you’ll need to charge the bike as a whole, which may be less convenient if you’re away from a power source. However, the charging speed is good compared to similar e-bikes, so you shouldn’t have to wait too long for a full charge. This setup is fine for most trail use, but if you frequently ride in remote areas, you’ll need to plan your charging stops carefully.
Is this bike good value for the price compared to similar mountain e-bikes?
The Trek Fuel EXe 9.8 is a premium mountain e-bike with a strong build quality, confident braking, and efficient battery use, but its lower motor power and battery capacity may not justify the price for riders focused on range or performance. While it feels stable and comfortable on trails, similar e-bikes in the same price range often offer more power, longer range, or removable batteries, which could be more practical for some riders. If you prioritize a lightweight, well-handling bike for trail riding and don’t need maximum power or range, it could be a good fit, but it may not be the most cost-effective choice compared to alternatives.
How comfortable is the bike on rough or uneven terrain?
The Trek Fuel EXe 9.8 should handle rough or uneven terrain well, thanks to its mountain bike design and hydraulic disc brakes, which provide confident stopping power on trails. The lightweight carbon frame and smooth power delivery should help maintain comfort and control over uneven surfaces, though the lower motor power and torque may require more effort on steep or technical sections.
Who is this bike best suited for, and who might find it less ideal?
This bike is best suited for riders who prioritize confident braking, smooth power delivery, and efficient battery use on trails and rough terrain. It’s a solid choice for those looking for a lightweight, well-handling mountain e-bike for regular off-road riding. However, riders who need strong motor power for steep climbs or long-distance adventures may find it less ideal, as the motor and battery capacity are on the lower end compared to similar models.
What are the main compromises or limitations of this bike?
The Trek Fuel EXe 9.8 has a few limitations that may affect certain riders. Its lower motor power and torque mean it won’t excel in steep climbs or high-speed acceleration, which could be a drawback for more aggressive trail riding. The battery capacity is also on the lower side for a mountain e-bike, providing a range that’s below average, so longer rides may require careful planning or carrying a spare battery. Additionally, the battery isn’t removable, which means you’ll need to charge the bike as a whole, limiting flexibility if you’re away from a power source.
