Overview
The CUBE STEREO HYBRID ONE44 EXC 800 is a mountain bike built for off-road adventures, offering a smooth and controlled power delivery that feels natural on trails. With a high-capacity battery and removable design, it provides flexibility for charging and storage, making it practical for longer rides. The hydraulic disc brakes offer confident stopping power, and the aluminium frame keeps the bike durable without being overly heavy. However, its 250W motor and lower power-to-weight ratio mean it won't feel as punchy when accelerating or climbing steep hills, and the battery efficiency is average for its size, so you might need to plan charging stops more carefully.
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 smooth power delivery make it a strong choice for those seeking consistent assistance on rough terrain. The front and rear suspension, combined with hydraulic disc brakes, provide comfort and confidence on uneven surfaces, making it a practical option for trail-focused riders.

Where to buy
Priced at £3,899, the CUBE STEREO HYBRID ONE44 EXC 800 looks favourably positioned against 2025 mountain e-bikes, offering strong battery capacity and responsive torque support for off-road use. Its main trade-off is a slightly longer charge time and a ride feel that may feel less agile compared to some rivals.
Compared with similar mountain bike e-bikes on Bikkerr, this model sits £1,759.07 below average
The CUBE STEREO HYBRID ONE44 EXC 800 is listed at £3,899, which positions it as a competitive option among 2025 mountain e-bikes, with its price looking favourable when compared to similar models from the same year. It offers a strong battery capacity and range that compare well with rivals, and the torque support feels natural and responsive, which is a key consideration for off-road performance. However, some similar e-bikes may offer a more lively ride for their weight, and the 6.5-hour charge time is slightly longer than what some competitors provide. For a mountain e-bike focused on trail comfort, braking confidence and battery endurance, this bike makes sense as a well-rounded package. Riders prioritising strong hill support, reliable braking and a robust battery for longer rides are likely to see the value here, though those seeking a lighter, more agile feel might find other options more appealing.

This mountain e-bike offers a balanced motor assistance that should feel natural and predictable on trails, with strong torque support to help with climbing and low-speed rough terrain. Next to similar models, it provides a solid level of assistance but may feel slightly less punchy or lively under heavy effort compared to some competitors. The torque and cadence sensor setup should help maintain smooth and responsive power delivery, especially when navigating technical trails or adjusting effort levels. While the motor may not be the most aggressive in its category, it should suit riders looking for reliable, controlled assistance that complements the bike's trail-focused design and suspension. This motor setup is likely to suit those prioritizing consistent support over aggressive acceleration 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 bike is well-suited for long off-road rides, thanks to its high battery capacity and smooth power delivery, which should help you cover more ground without frequent stops. The hydraulic disc brakes provide confident stopping power on rough terrain, and the mountain bike design ensures good trail handling. However, the 250W motor and average battery efficiency mean you may need to plan charging stops more carefully, especially on longer or more demanding rides.
How does the motor perform when climbing steep trails?
The motor provides smooth and controlled assistance, but it may struggle on very steep trails due to its 250W power and lower power-to-weight ratio. While the above-average torque helps with climbing, you may find yourself needing to pedal more actively on steep inclines. This bike is better suited for moderate trails rather than extremely steep climbs.
Does the bike handle rough terrain comfortably?
The CUBE STEREO HYBRID ONE44 EXC 800 is built for off-road use, with a sturdy frame and hydraulic disc brakes that provide confident stopping power on rough terrain. While the 250W motor and above-average torque offer smooth assistance, it may feel less punchy when accelerating or climbing steep trails. The high battery capacity supports longer rides, but the average battery efficiency means you should plan for charging stops, especially on more demanding trails.
Is the battery capacity sufficient for extended rides?
The 800Wh battery offers a high capacity, which should support extended rides, especially on trails where you can manage your speed and terrain. With a range of around 75 miles, it's well-suited for longer off-road trips, though you may need to plan charging stops depending on your riding style and conditions. The removable battery adds convenience for charging and storage, making it practical for multi-day adventures.
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 design also makes it easier to store the battery separately when not in use, though you should keep in mind that the battery capacity is high, so it will take longer to charge than some smaller batteries.
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 removable design, which adds convenience for charging and storage. 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 price reflects its strong off-road capabilities and range, making it a good value for riders focused on extended rides and trail performance.
How does the bike's weight affect its portability and handling?
The bike weighs 26.2 kg, which is above average for a mountain e-bike, so it may feel heavier to carry, especially when lifting it onto a vehicle or carrying it over obstacles. On the trail, the weight provides stability at higher speeds and over rough terrain, but it might feel less nimble compared to lighter models. However, the aluminium frame helps keep the weight manageable for its category, and the motor's torque should assist with climbing without requiring excessive effort.
What are the main limitations of this e-bike's motor and battery performance?
The main limitations of this e-bike's motor and battery performance are its 250W motor, which provides smooth support but may feel less punchy when accelerating or climbing steep trails, and its average battery efficiency, which means you might need to plan charging stops more carefully on longer rides. While the 800Wh battery offers a high range, the slower charging time could be inconvenient if you need to recharge quickly.
