Overview
The CUBE STEREO HYBRID ONE44 EX 800 is a mountain bike built for off-road trails, offering a smooth and capable ride with its front and rear suspension. Its 800Wh battery provides a good range for longer rides, and the removable battery adds convenience for charging and storage. The motor delivers steady support for trail riding, though it lacks the punch for steep climbs or rapid acceleration. Weighing 26kg, it feels solid but may be harder to lift, and the 6.5-hour charge time is notably slow compared to similar models.
Best For
✓
This mountain e-bike should suit riders who prioritize off-road performance and want a reliable companion for trail riding and longer adventures. Its high battery capacity and strong motor power make it well-suited for extended rides on rough terrain, while the front and rear suspension offer comfort and control on uneven surfaces. The removable battery adds flexibility for charging away from the bike, which is especially useful for riders who travel to remote areas or need to manage battery life efficiently.
Who Should Avoid It
×
Riders seeking the most responsive motor assistance or faster charging times may be better served by comparing alternatives.

This mountain e-bike offers a balanced motor assistance that should feel natural and proportional to rider effort, with strong torque support for climbing and low-speed trail riding. Next to similar models, it provides a smooth and responsive ride, though some e-bikes in the category may feel more punchy or lively for their weight. The torque should help with climbing and rough terrain, though the motor power may feel modest compared to more aggressive trail e-bikes. With a torque sensor, the assistance should feel intuitive and well-matched to the bike's trail-focused design, making it a solid choice for riders prioritizing control and consistency over raw power. This setup is likely to suit those looking for a reliable, predictable motor feel on varied off-road terrain.
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 of 800Wh, which provides a good range for extended adventures. The front and rear suspension should offer comfort on rough terrain, and the removable battery adds convenience for charging and storage. However, the motor's 250W power and low power-to-weight ratio may make steep climbs or rapid acceleration feel less responsive, so you may need to pace yourself on challenging trails.
How does the motor perform when climbing steep trails?
The motor provides steady support for trail riding, but it may struggle with very steep climbs due to its 250W power and average efficiency. While the 85Nm torque helps with hill climbing, the motor lacks the punch for rapid acceleration or extremely steep terrain. For most trails, it should be adequate, but riders looking for aggressive climbs may find it a bit limited.
Does the bike handle rough terrain comfortably?
This mountain bike is designed for rough terrain, with front and rear suspension that should help absorb shocks and provide a smoother ride over uneven trails. While the motor offers steady support, it may not deliver the strongest acceleration or power for very technical or steep sections, so you may need to adjust your expectations for intense off-road challenges.
Is the battery capacity enough for extended adventures?
The 800Wh battery should provide enough range for most extended off-road adventures, especially given its high capacity compared to similar e-bikes. With a range of around 75 miles, it's well-suited for longer rides, though you may need to plan charging stops for multi-day trips. The removable battery adds convenience for charging and storage, making it easier to manage power needs on the go.
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, though you should keep in mind that the bike’s overall weight is above average, which might make lifting it more challenging when the battery is installed.
Is this bike good value for money compared to similar e-bikes?
This bike offers a solid balance of features for its price, especially with its high battery capacity and strong off-road performance. While the motor power is on the lower end for mountain e-bikes, the 800Wh battery and removable design add practicality for longer rides and charging convenience. At £3899, it's competitive with similar models, though the slower charging time and heavier weight may be considerations for some buyers.
How does the weight of the bike affect its portability and handling?
The bike weighs 26kg, which is above average for a mountain e-bike, making it slightly harder to lift or carry when needed. This weight can also affect handling on rough terrain, where a lighter bike might feel more agile. However, the added mass contributes to stability at higher speeds and over uneven ground, which is generally a positive trait for off-road riding.
What are the main limitations of this e-bike for serious mountain biking?
This e-bike is well-suited for off-road trails, but it may struggle with very steep climbs or rapid acceleration due to its 250W motor, which provides smooth support but lacks the punch of more powerful models. The 26kg weight makes it feel solid on trails but could be a challenge to lift, especially after long rides. While the 800Wh battery offers a good range for extended adventures, the 6.5-hour charge time is notably slow compared to similar e-bikes, which might be a limitation for frequent riders.
