Overview
The Trek Fuel+ MX 9.8 XT Gen 2 is a capable mountain e-bike designed for trail riding, offering a responsive feel and strong braking confidence thanks to its hydraulic disc brakes. Its 600W motor and 60Nm of torque provide smooth support for most terrain, though it may struggle on very steep inclines. The front and rear suspension ensures a comfortable ride over rough surfaces, but the bike's 50km range and 580Wh battery mean longer rides require careful planning. While its carbon frame and power-to-weight ratio make it lively for its size, the non-removable battery limits charging flexibility, and the charging time is on the slower side for an e-bike of this class.
Best For
✓
This mountain e-bike should suit riders who prioritize performance on rough trails and want a responsive ride with strong braking and suspension comfort. Its high power-to-weight ratio and hydraulic disc brakes make it well-suited for confident trail riding and controlled descents. The front and rear suspension should provide good comfort and control on uneven terrain, making it a solid choice for more technical off-road routes. Riders who value a balance of power, control, and comfort on challenging trails are likely to appreciate this bike’s capabilities.
Who Should Avoid It
×
Riders who frequently tackle long off-road rides or steep inclines may want to compare alternatives, as the bike's range and torque are below average for similar mountain e-bikes. Riders who prioritize a removable battery for convenience or faster charging may also find stronger options available within the same category. However, the bike still offers a strong power-to-weight ratio and confident braking, making it a solid choice for riders focused on trail performance and comfort.

Where to buy
Priced at £7,625, the Trek Fuel+ MX 9.8 XT 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+ MX 9.8 XT Gen 2 is listed at £7,625, which is on the higher side when compared with 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, and the hydraulic disc brakes and dual suspension provide solid control and comfort on rough terrain. However, some similar e-bikes may offer a larger battery, more range, or stronger climbing support, which could be important for riders tackling longer or more challenging trails. For this mountain e-bike, the trade-off seems to be between a lighter, more agile frame and a slightly more modest battery capacity, which may affect range and charging flexibility. Riders who prioritise agility, responsiveness and performance on technical trails may find the value case 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 motor support is competitive but may not match the strongest climbers or low-speed push of some alternatives. Climbing steeper terrain may require more effort from the rider, especially on technical sections, though the motor should still provide solid support for moderate trails. The bike's assistance likely feels adjustable with multiple ride modes, though power delivery may feel less refined compared to some similar e-bikes. Riders looking for a lightweight trail e-bike with strong acceleration and good responsiveness, but who may need to plan for shorter rides or less intense climbs, should find this motor setup a reasonable fit.
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 hydraulic disc brakes that offer confident stopping power and front and rear suspension that improves comfort on rough terrain. However, its 50-mile range and 580Wh battery may require careful planning for longer rides, and the non-removable battery can make charging less convenient if you're away from a power source.
How does the motor perform when climbing steep trails?
The motor should provide smooth support for most trail climbing, but it may struggle on very steep inclines due to its lower torque compared to similar e-bikes. With 600W of power and 60Nm of torque, it should handle moderate hills well, but riders aiming for extremely steep trails may need to manage their effort and use lower assistance modes to conserve battery. The bike's power-to-weight ratio helps with acceleration, but the motor's performance on steep climbs will depend on terrain and rider input.
Does the bike's suspension provide enough comfort on rough terrain?
The Trek Fuel+ MX 9.8 XT Gen 2 features front and rear suspension that should significantly improve comfort on rough terrain, making it suitable for trail riding and uneven surfaces. While the suspension is designed to handle rough conditions, the bike's 50-mile range and 580Wh battery may require careful planning for longer rides. The suspension should provide a balanced ride without being overly aggressive, making it a good choice for most trail conditions.
Is the battery capacity sufficient for multi-day adventures?
The 580Wh battery provides a range of around 50 miles, which may be enough for a day's ride but not ideal for multi-day adventures without careful planning. Since the battery isn't removable, you'll need to charge the bike near a power source, which can be inconvenient for extended trips. For longer rides, you may want to carry a spare battery or plan charging stops in advance.
How practical is this bike for everyday use and charging?
This bike is well-suited for regular trail use, but charging may be less convenient due to the non-removable battery. You'll need to keep the bike near a power source to recharge, which could be a limitation if you're frequently on the move. The 50-mile range is adequate for most day rides, but longer trips will require careful planning and possibly carrying a spare battery or charging on-site.
Who is this bike best suited for?
This bike is best suited for experienced trail riders who prioritize braking confidence and suspension comfort over long-range capabilities. The hydraulic disc brakes and dual suspension make it a solid choice for rough terrain, but the below-average range and non-removable battery mean it's more practical for shorter off-road rides or those with access to charging points. Its high power-to-weight ratio also makes it a good fit for riders looking for a lively, responsive e-bike for technical trails.
Is this bike good value for the price compared to similar models?
The Trek Fuel+ MX 9.8 XT Gen 2 offers a strong set of features for a mountain e-bike, including a powerful motor, confident braking, and good suspension, which make it well-suited for off-road trails. However, its below-average range and battery capacity may require more careful planning for longer rides, and the non-removable battery can be a limitation for some users. At £7,625, it's positioned as a premium option, so buyers should consider whether the performance and build quality justify the cost compared to other high-end mountain e-bikes in the same category.
What are the main compromises of this bike?
The main compromises of this bike include its limited range and battery capacity, which may require careful planning for longer rides. The non-removable battery also makes charging less convenient, especially if you're away from a power source. While the motor provides strong support for most trails, its lower torque may make very steep climbs more challenging compared to similar e-bikes.
