This mountain e-bike offers legal-style pedal assist with strong torque support that should feel effective on climbs and low-speed rough terrain. Next to similar models, it provides a balanced and predictable assistance feel, though some e-bikes in the category may offer more immediate motor punch or feel livelier for their weight. The torque sensing should help maintain control on technical trails, and the assistance should feel responsive without being overly aggressive. Riders looking for a reliable and smooth motor experience that prioritizes trail control and longer rides 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 bike is well-suited for long off-road rides, thanks to its high battery capacity and strong range, which should support extended adventures. The hydraulic disc brakes provide confident stopping power on rough trails, and the removable battery adds convenience for charging and storage. However, the motor may feel less punchy when accelerating, and the bike's weight could make it slightly harder to carry, especially after long rides.
How does the motor perform when climbing steep trails?
The motor provides smooth support for moderate climbs but may struggle on very steep trails. With 250W of power and 85Nm of torque, it's adequate for most trail conditions but not the most punchy when accelerating or tackling extremely steep inclines. You'll likely need to pedal more actively on very steep sections, especially if the trail is rough or technical.
Is the battery capacity enough for multi-day adventures?
The 800Wh battery should provide enough range for multi-day adventures, especially with the high range rating for this type of e-bike. However, the battery efficiency is average, so you may need to plan charging stops, particularly if you're riding aggressively or in hilly terrain. The removable battery makes it easier to charge and store, which is a practical advantage for longer trips.
How does the bike handle rough terrain and trail control?
The Cube Reaction Hybrid SLX 800 FE Easy Entry handles rough terrain well, thanks to its mountain bike design and hydraulic disc brakes, which provide confident stopping power on uneven trails. The bike's trail control should feel solid for most off-road conditions, though its 250W motor may feel less punchy when accelerating or climbing steep sections. With a high battery capacity and removable design, it's practical for longer rides, but its weight may make it slightly harder to lift or maneuver in tight spaces.
Is this bike good value for money compared to similar mountain e-bikes?
This bike offers good value for money when compared to similar mountain e-bikes, especially considering its high battery capacity and removable design, which adds convenience for charging and storage. While the motor power is on the lower end for this type of bike, the above-average torque and strong off-road capability make it a solid choice for trail riding. The price reflects a balance of features that should appeal to riders looking for a reliable mountain e-bike without breaking the bank.
How practical is the removable battery for charging and storage?
The removable battery is very practical for charging and storage, as it allows you to easily take the battery off the bike for charging at home or on the go. This feature is especially useful if you're riding in remote areas or need to store the bike in a small space. The high battery capacity also means you can enjoy longer rides without needing to recharge frequently.
Is the bike heavy to carry, and how does that affect usability?
The Cube Reaction Hybrid SLX 800 FE Easy Entry weighs 26.8kg, which is above average for a mountain e-bike, so it may feel heavier to carry, especially when lifting it onto a vehicle or over obstacles. While this weight is typical for a mountain bike with a powerful motor and large battery, it could make the bike less convenient for frequent carrying or transporting. However, the hydraulic disc brakes and robust frame help maintain control and stability on rough trails, which is more important for off-road usability than the weight itself.
What are the main compromises or trade-offs of this bike?
The main trade-offs of this bike include its lower motor power, which may feel less punchy when accelerating and could struggle on very steep climbs. It also has a slower charging time compared to similar e-bikes, which might be inconvenient if you need to recharge quickly. While the bike is heavier than average, it's still manageable for most trail use, but lifting it may be more challenging. However, the high battery capacity and removable design offer strong practicality for longer rides and charging flexibility.
