Overview
The CUBE Reaction Hybrid Pro 800 is a mountain bike designed for off-road trails, offering smooth motor support and reliable braking for varied terrain. Its 800Wh battery provides a good range for longer rides, and the removable battery adds convenience for charging and storage. While the motor delivers controlled assistance, it lacks the punch for quick acceleration or steep climbs. The bike's weight also makes it slightly less easy to lift, which could be a consideration for some riders.

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 hydraulic disc brakes, which provide confidence on varied terrain. The 800Wh battery offers a good range for extended trips, and the removable battery adds convenience for charging. However, the motor's lower power and the bike's above-average weight may affect performance on steep climbs or when quick acceleration is needed.
How does the motor perform when climbing steep trails?
The motor provides controlled assistance that should help with moderate climbs, but it may struggle on very steep trails due to its lower power output. With 85Nm of torque, it offers decent support for most off-road conditions, but riders looking for quick acceleration or steep hill climbing may find the motor less responsive. The bike's weight also adds to the challenge of lifting and maneuvering on steep inclines.
Does the bike handle rough terrain comfortably?
The CUBE Reaction Hybrid Pro 800 is built for off-road use and should handle rough terrain comfortably, thanks to its mountain bike design and hydraulic disc brakes, which provide confident stopping power on trails. The 800Wh battery offers a good range for longer rides, though the motor’s 250W power may feel less punchy when accelerating or climbing steep sections. The bike’s weight is above average, which might make it slightly harder to lift or maneuver in tight spaces, but it’s still well-suited for most trail conditions.
Is the battery capacity enough for multi-day adventures?
The 800Wh battery should provide enough range for multi-day adventures, especially with the bike's high range rating for a mountain e-bike. However, the battery efficiency is average, so you may need to plan charging stops or carry a spare battery for longer trips. The removable battery adds convenience for charging and storage, which is helpful for multi-day rides.
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 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 if you have limited space at home. The design ensures you don't have to worry about charging the bike in less-than-ideal environments, adding to its convenience for off-road use.
Is this bike good value for its price compared to similar e-bikes?
The CUBE Reaction Hybrid Pro 800 offers a solid balance of features for its price, especially with its high battery capacity and strong braking performance. While the motor power is on the lower end for mountain e-bikes, the torque and smooth power delivery should still handle most trails effectively. The weight is slightly above average, which may affect portability, but the removable battery adds convenience for charging and storage. Overall, it's a good value for riders prioritizing range and off-road capability over quick acceleration or steep hill climbing.
How does the weight affect portability and handling?
The CUBE Reaction Hybrid Pro 800 weighs 25.6 kg, which is above average for a mountain e-bike. This makes it slightly more challenging to lift or carry, especially when navigating rough terrain or loading it into a vehicle. However, the weight is balanced well for off-road performance, providing stability and control on trails. While it may not be the lightest option, the weight doesn't significantly hinder handling on most trails.
What are the main limitations of this bike for serious off-road use?
This bike is designed for off-road use, but its 250W motor may lack the punch for quick acceleration or very steep climbs. While the torque is above average, it may not provide the strongest hill-climbing support for more demanding trails. The bike's weight of 25.6kg also makes it slightly harder to lift or maneuver in tight spaces, which could be a consideration for serious off-road riders who need to carry or transport the bike frequently.
