Motor Name
Bosch Performance Line CX (Generation 5 / BDU 384 Y)
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 provides a balanced and predictable assistance feel with torque and cadence sensing helping to maintain control on trails. The motor should support climbing and technical riding reasonably well, though some similar e-bikes may offer more outright punch or liveliness for their weight. The assistance should feel smooth and responsive, with ride modes likely allowing adjustment for different trail conditions. Riders looking for a reliable and natural-feeling motor that supports off-road riding without prioritizing maximum speed may find this setup well-suited to their needs.

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 mountain bike design, which should provide good trail control and comfort. The hydraulic disc brakes offer confident stopping power, which is essential for rough terrain. However, the bike's weight and lower motor power may make steep climbs and quick acceleration feel less responsive, so you may need to pace yourself on very challenging trails.
How does the motor perform when climbing steep trails?
The motor should provide adequate support for moderate climbs, but steep trails may feel challenging due to the 250W motor power and the bike's above-average weight. While the above-average torque of 85Nm helps with climbing, the overall power-to-weight ratio is low, which may make steep ascents feel less responsive. For serious mountain biking, you might find a more powerful motor beneficial for steeper or more technical trails.
Does the bike handle rough terrain comfortably?
The CUBE Reaction Hybrid Race 800 FE should handle rough terrain comfortably, thanks to its mountain bike design and hydraulic disc brakes, which offer confident stopping power on trails. The high battery capacity supports longer rides, but the bike's weight may make it feel less agile on technical terrain. While it's well-suited for most off-road conditions, riders looking for lightweight agility might find the frame's bulk a slight limitation.
Is the battery capacity enough for extended adventures?
The 800 watt-hour battery should provide a good range for extended off-road adventures, especially considering it's rated for 75 miles on a single charge. This makes it suitable for longer rides on trails, though you may need to plan for charging stops if you're pushing the range further. The removable battery adds convenience for charging and storage, which is helpful for multi-day trips or when you need to recharge without carrying the whole bike.
How practical is the removable battery for charging and storage?
The removable battery is quite practical for charging and storage, as it allows you to take the battery indoors to charge it safely, which is especially useful if you're riding in wet or muddy conditions. This feature also makes it easier to store the battery separately when not in use, which can be helpful for travel or when you need to free up space. However, the battery's high capacity means it may take longer to charge compared to smaller batteries on similar e-bikes.
Is this bike good value for its price and features?
The CUBE Reaction Hybrid Race 800 FE offers a strong feature set for a mountain e-bike, including a high-capacity battery, excellent braking, and good off-road capability. However, its lower motor power and heavier weight may limit performance on steep climbs and quick acceleration. At £3299, it's a solid choice for riders prioritizing range and trail control, but those needing faster charging or more responsive power might find it less ideal for their needs.
How does the bike's weight affect its portability and handling?
The CUBE Reaction Hybrid Race 800 FE weighs 26.9 kg, which is above average for a mountain e-bike. This weight makes it less convenient to carry or lift, especially when moving it between trails or storing it. However, the heavier frame contributes to stability on rough terrain, which can improve handling in challenging off-road conditions.
What are the main limitations of this e-bike for serious mountain biking?
This e-bike is well-suited for trails and off-road riding, but it may struggle with very steep climbs or rapid acceleration due to its lower motor power. The bike's weight, while typical for a mountain e-bike, could make it harder to carry or lift when needed. For serious mountain biking, these factors might limit performance on more demanding terrain.
