Overview
The CUBE Reaction Hybrid ONE 800 is a mountain bike designed for off-road trails, offering a solid balance of power and practicality. With a high-capacity battery and removable design, it provides good range and flexibility for charging and storage, making it a reliable choice for longer rides. The hydraulic disc brakes offer confident stopping power, and the torque sensor ensures smooth motor support for varied terrain. However, its 250W motor may feel less punchy when accelerating, and the bike's weight makes it slightly harder to lift, which could be a consideration for frequent porters. While it's well-suited for trail riding, its charging time is on the slower side compared to similar models.

Motor Name
Bosch Performance Line CX (Gen 5)
This mountain e-bike offers legal-style pedal assist with strong torque support that should feel capable on climbs and low-speed rough terrain. Next to similar models, its assistance should feel reasonably balanced but not the most punchy, with some e-bikes in the category offering more outright power. The torque sensing should help the motor respond naturally to pedaling effort, making the assistance feel more intuitive on trails. Riders wanting predictable support with good control over assistance levels may find this setup suits them well, especially for longer rides where range is a priority.
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 bike is well-suited for long off-road rides, thanks to its high battery capacity and strong braking performance. The hydraulic disc brakes provide confident stopping power on rough terrain, and the high range should support extended trail sessions. However, the 250W motor may feel less punchy when accelerating, and the bike's weight could make it slightly harder to carry, which might be a consideration for frequent trail porters.
How does the motor perform when climbing steep trails?
The motor provides smooth support for climbing steep trails, but the 250W power and average battery efficiency may make it less punchy on very steep or technical sections. The above-average torque helps with maintaining momentum, but riders may need to manage their speed and effort, especially on longer climbs. This bike is better suited for moderate to challenging trails rather than extremely steep or sustained ascents.
Does the battery last long enough for multi-day adventures?
The CUBE Reaction Hybrid ONE 800 has a high battery capacity of 800 watt-hours, which should provide a range of around 75 miles on a single charge. This makes it a solid option for multi-day adventures, especially when combined with the removable battery feature, which allows you to charge it separately or swap it out for extended trips. However, the average battery efficiency and slower charging time compared to similar models mean you should plan for regular charging stops, particularly if you're riding aggressively or in hilly terrain.
How does the bike handle rough terrain and trail conditions?
The CUBE Reaction Hybrid ONE 800 handles rough terrain and trail conditions well, thanks to its mountain bike design and hydraulic disc brakes, which provide confident stopping power on varied surfaces. The 85 Nm torque offers smooth motor support for climbing and uneven trails, though the 250W motor may feel less punchy when accelerating. With a high range of 75 miles, it's suitable for extended trail rides, but its weight of 26.9 kg might make it slightly harder to carry or lift when needed.
Is this bike good value for money compared to similar e-bikes?
The CUBE Reaction Hybrid ONE 800 offers strong value for money, especially considering its high battery capacity and removable design, which adds flexibility for charging and storage. While the 250W motor may not be the most powerful in its class, the above-average torque helps with trail performance, and the hydraulic disc brakes provide confident stopping power. At £2699, it's a solid choice for off-road riders looking for a reliable e-bike with good range and practical features, though you may find faster charging or more punchy acceleration on some competing models.
How practical is the removable battery for everyday use?
The removable battery is quite practical for everyday use, as it allows you to charge the battery separately from the bike, which can be convenient if you're at home or a trailhead. This feature also makes it easier to store the battery when not in use or transport it separately. However, since the battery is high capacity, it may take longer to charge compared to smaller batteries on similar models.
Is this bike heavy to carry or lift, especially when off-road?
The CUBE Reaction Hybrid ONE 800 weighs 26.9 kg, which is above average for a mountain e-bike, so it may feel heavier to carry or lift, especially when off-road. This weight can make it a bit more challenging to maneuver over rough terrain or when you need to lift it, such as when navigating obstacles or carrying it on a trail. However, the removable battery adds some practicality for charging and storage, which can help offset the weight concern a bit in everyday use.
What are the main limitations of this bike for serious mountain biking?
This bike is well-suited for trail riding, but it may struggle with very steep climbs due to its 250W motor, which offers smooth support but lacks the punch for aggressive ascents. Its weight of 26.9kg also makes it harder to lift, which could be a drawback if you frequently need to carry it. While the hydraulic disc brakes provide confident stopping power, the slower charging time and average battery efficiency might limit its practicality for multi-day adventures without access to charging facilities.
