Overview
The CUBE Reaction Hybrid Pro 800 FE is a capable mountain bike designed for trail riding, offering smooth motor support and reliable braking for varied terrain. Its high-capacity battery and removable design make it practical for longer rides and easy charging, while the torque and cadence sensor ensures a natural feel when climbing or cruising. However, its 250W motor and moderate torque may feel less punchy when accelerating or tackling steep inclines, and the 6.5-hour charge time could be a consideration for frequent users. At 27.5kg, it's not the lightest option, which might make lifting it more effort, but its overall balance of range and trail suitability makes it a solid choice for off-road enthusiasts.

The CUBE Reaction Hybrid Pro 800 FE is listed at £3,099, which sits comfortably against similar mountain e-bikes from 2025, offering a price that feels reasonable for the features included. It compares well with rivals in terms of range, battery capacity and torque support, which should help with hill climbing and trail confidence, while the hydraulic disc brakes add a layer of control that many similar bikes may lack. However, some alternatives might feel more responsive for their weight, and a few may handle heavier loads better, which could be important for riders who carry more gear or tackle more demanding trails. For a mountain e-bike focused on trail performance and battery endurance, the price is easier to understand when considering the strong support and control features. Riders prioritising reliable hill support, good battery life and confident braking are likely to see the value in this package, though those needing faster charging or more agile handling might find trade-offs worth considering.

This mountain e-bike offers a legal-style pedal assist with strong torque support that should feel capable on climbs and low-speed rough terrain. Next to similar models, it delivers a balanced and natural assistance feel with torque and cadence sensing, though some e-bikes may offer more outright punch or feel livelier for their weight. The motor should provide confident support on technical trails and loaded riding, with predictable assistance that adapts to pedaling effort. The combination of torque and sensor type should help maintain control and responsiveness, especially on uneven ground. Riders looking for a reliable and smooth motor experience on trails, with good range for longer rides, should 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-capacity battery, which offers a range of 75 miles, and its hydraulic disc brakes, which provide confident stopping power on rough terrain. The removable battery also makes it practical for longer trips, as you can charge it separately when needed. However, the 250W motor and moderate torque may feel less punchy when accelerating or climbing very steep trails, and the 6.5-hour charge time could be a consideration for frequent riders.
How does the motor perform when climbing steep trails?
The motor provides smooth and controlled assistance when climbing steep trails, but its 250W power and moderate torque may feel less punchy when accelerating or tackling very steep inclines. While the torque and cadence sensor help deliver a natural feel, riders looking for more aggressive hill-climbing performance might find this bike better suited for moderate trails rather than extremely steep terrain.
Does the battery last long enough for multi-day adventures?
The CUBE Reaction Hybrid Pro 800 FE offers a range of 75 miles on a single charge, which should be sufficient for multi-day adventures, especially when planning routes and managing battery usage. The high-capacity 800Wh battery and removable design make it practical for longer trips, allowing you to charge it easily when needed. However, with a 6.5-hour charge time, it's worth considering how often you'll need to recharge, particularly if you're riding multiple days in a row.
How easy is it to charge and replace the battery?
The battery is removable, which makes it easy to charge separately from the bike, especially useful if you're on the go. However, the charging time is on the longer side at around 6.5 hours, so you may need to plan ahead for longer rides. The removable design is practical for storage and handling, but the slower charge time could be a consideration for frequent users.
Is this bike comfortable for rough terrain and trails?
This bike is designed for trail riding and should handle rough terrain reasonably well, thanks to its mountain bike frame and hydraulic disc brakes, which provide confident stopping power on varied surfaces. The 85 Nm torque and cadence sensor help deliver smooth assistance when climbing or cruising, though the 250W motor may feel less punchy on steep inclines. At 27.5kg, it's not the lightest option, which could make lifting it more effort, but its high battery capacity and removable design make it practical for longer rides and easy charging.
How does the weight of the bike affect its handling and portability?
The CUBE Reaction Hybrid Pro 800 FE weighs 27.5kg, which is above average for a mountain e-bike. This weight can make the bike feel less nimble on technical trails and more effortful to lift when carrying it, especially after long rides. However, the added mass is balanced by its robust frame and high-capacity battery, which contribute to stability and longer range on rough terrain. While it's not the lightest option, its weight is typical for a mountain e-bike designed for durability and off-road performance.
Is this bike good value for its features and performance?
The CUBE Reaction Hybrid Pro 800 FE offers a strong balance of features for a mountain e-bike, especially with its high battery capacity and reliable braking for off-road use. While the 250W motor and moderate torque may not be the most powerful for steep climbs, the smooth power delivery and long range make it a solid choice for trail riding. At £3099, it's reasonably priced for its performance and practicality, though the weight and slower charging time might be considerations for some riders.
What are the main limitations or trade-offs of this bike?
The CUBE Reaction Hybrid Pro 800 FE has a 250W motor, which may feel less punchy when accelerating or climbing steep trails, especially when compared to more powerful models. While the 85Nm torque helps with climbing, it's not the highest in its class, so steeper inclines might require more effort. The bike also weighs 27.5kg, which is above average for a mountain e-bike, making it slightly harder to lift or carry when needed. Additionally, the 6.5-hour charge time is relatively slow, which could be a drawback for riders who need to recharge frequently.
