The Trek Slash+ 9.7 is listed at £6,000, which sits broadly in line with similar mountain e-bikes from 2026, though it may feel demanding when compared to some alternatives in the broader category. Its power-to-weight ratio is a strong point, with a 600W motor and 60Nm of torque working well against its 21.58kg frame, making it competitive for trail performance. Hydraulic disc brakes and front-and-rear suspension also add to its appeal for off-road use. However, some similar e-bikes may offer a larger battery or more range, and the non-removable battery could be a drawback for riders who need flexibility in charging. For a mountain e-bike focused on trail performance and control, the Slash+ 9.7 makes sense for buyers prioritising responsiveness and suspension over extended range. Riders who need more battery capacity or easier charging might find value elsewhere, but those looking for a well-rounded trail machine will likely see the price as justified.

Motor Name
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 give riders good control over the assistance, especially when navigating trails with varying demands. Riders looking for a responsive trail e-bike with balanced efficiency and a lighter design 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?
The Trek Slash+ 9.7 is built for off-road trails with its mountain bike design, suspension system, and hydraulic disc brakes, which should give you confidence on rough terrain. However, the battery capacity is below average for this type of e-bike, so you may need to plan for more frequent charging on longer rides. The motor provides strong power, but the lower torque might make steep climbs feel a bit more effortful, especially over extended distances.
How does the motor perform when climbing steep trails?
The motor should provide strong assistance when climbing steep trails, thanks to its 600W power and high power-to-weight ratio. However, the lower torque of 60Nm may make very steep or technical climbs feel slightly less responsive, especially if you're carrying extra weight or riding at higher speeds. For most trail conditions, the motor should feel adequate, but riders focused on extremely challenging climbs may want to plan for more frequent stops to recharge.
Does the bike offer good comfort on rough and uneven terrain?
The Trek Slash+ 9.7 should feel comfortable on rough and uneven terrain thanks to its front and rear suspension, which should help absorb shocks and improve handling over rough surfaces. While the motor provides strong power for trail riding, the lower torque may affect acceleration on particularly challenging sections. Overall, it's a solid choice for riders looking for comfort and control on varied off-road trails.
Is the battery capacity sufficient for extended mountain biking sessions?
The battery capacity of 580 watt-hours is on the lower side for mountain e-bikes, which may limit how far you can ride on a single charge, especially on challenging trails. This means you'll need to plan for more frequent charging stops during extended sessions. While the motor provides strong power, the battery's efficiency and capacity may require careful management if you're riding for long periods in the mountains.
How practical is this bike for daily use, especially with its non-removable battery?
The non-removable battery means you'll need to charge the bike near a power source, which can be inconvenient if you're planning to ride multiple times in a day or need to recharge quickly. While the bike is well-suited for trail riding and off-road use, the battery's lower capacity and slower charging time may require more careful planning for daily use, especially if you're covering longer distances or riding frequently.
Who is this bike best suited for, given its strengths and limitations?
This bike is best suited for trail riders who prioritize power and braking confidence over long-range capabilities. The high motor power and hydraulic disc brakes make it a strong performer on rough terrain and technical trails, while the carbon frame and suspension ensure comfort. However, the lower battery capacity and slower charging time mean it's more suited for shorter or planned rides rather than extended off-road adventures.
Is this bike good value for money compared to similar mountain e-bikes?
The Trek Slash+ 9.7 offers strong performance for trail riding with its powerful motor and confident braking, but its lower battery capacity and slower charging time may require more planning for longer rides. At £6000, it's a premium option that prioritizes trail control and comfort over extended range, so it's best suited for riders who value off-road capability and don't need to cover long distances in one go.
What are the main compromises of this bike for serious off-road enthusiasts?
For serious off-road enthusiasts, the main compromises of the Trek Slash+ 9.7 include its lower battery capacity and slower charging time, which may limit ride duration and convenience on extended trips. The motor's torque is also on the lower side compared to similar e-bikes, which could affect performance when climbing steep trails. While the bike offers strong power and confident braking, these factors may require more careful planning for longer or more demanding off-road adventures.

The Slash+ 9.7 is a capable and rowdy mid-assist e-MTB ready to tackle dicey, wild and long rides. It loads you up with the smooth assist of TQ's HPR 60 motor with a 580 Wh battery for plenty of boost on the ups without compromising ride feel on the downs. You get a rugged OCLV Mountain Carbon frame decked out with a SRAM Eagle12-speed transmission and a Fox Performance suspension package for cutting loose when the trail gets spicy. High-pivot suspension The Slash's high main pivot allows the axle to move rearward as the suspension compresses, so the back wheel moves with the force from bumps and gets out of the way faster. On the trail, it feels ultra-smooth while maintaining more momentum with insane traction. Curb the kickback The Slash+'s oversized upper idler not only eliminates pedal kickback caused by high pivot suspension, but its size and position also give you just the right amount of anti-squat for efficient pedalling. The integrated lower chain guide takes chain tension off the derailleur, so you get smoother shifting and suspension performance. Mixed wheel size You get a 29" front wheel for monster truckin' over stuff, with a smaller 27.5" wheel out back for getting rowdy. Adjust the suss for full send Adjust the leverage rate with just a flip of a chip. Ride it in the Less progressive setting for a plusher feel perfect for rugged trails with square-edge bumps. Flip it to More progressive when you're hitting big features and don't want to bottom-out, or when you want to run a coil shock. Slack or steep, the choice is yours Install angle-adjust headset cups (sold separately) to tweak the head tube angle a degree steeper or slacker to your liking - all without impacting your bottom bracket height. TQ-HPR50 - small, quiet, mighty The TQ-HPR50 motor is super-efficient with an amazing power-to-weight ratio. Most motors use gears and belts that take up space and can make noise or break. The TQ-HPR50 uses a harmonic pin-ring drive transmission that's small, ultra-quiet and unbelievably natural-feeling.
