The CUBE STEREO HYBRID ONE77 HPC AT 800 is listed at £6,499, which places it at the higher end of the price spectrum when compared with similar mountain e-bikes from 2025. It offers a strong battery capacity and range that compare well with many rivals, and the torque support and hydraulic braking provide a confident, controlled ride on rough terrain. However, some similar e-bikes may feel more responsive for their weight, and the 6.5-hour charge time is longer than what some competitors offer. For a mountain e-bike focused on trail comfort, battery endurance and braking performance, this bike makes sense as a premium option, though buyers should weigh whether the price is justified by the level of off-road capability and build quality. Riders prioritising long-range support and reliable stopping power on technical trails are most likely to see the value in this package.

This mountain e-bike offers a balanced motor assistance that should feel natural and predictable on trails, with strong torque support helping on climbs and rough terrain. Next to similar models, it provides a solid level of assistance but may feel slightly less punchy or lively under heavy effort. The torque and cadence sensor should help maintain smooth and responsive power delivery, especially when navigating technical trails or maintaining control at low speeds. While it may not match the outright acceleration of some heavier, more powerful e-bikes, its assistance should suit riders looking for a well-rounded trail experience with good range and predictable support. Riders prioritizing climbing and trail control over raw acceleration may find this motor setup particularly well-suited to their needs.
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 and smooth power delivery, which should help you cover more ground without needing to recharge. The hydraulic disc brakes provide confident stopping power on rough terrain, and the carbon frame and suspension contribute to a comfortable ride over varied trails. However, the 250W motor may feel less punchy when accelerating, and the relatively slow charging time could be a consideration for frequent riders.
How does the motor perform when climbing steep trails?
The motor provides smooth and controlled assistance, which should help with climbing steep trails, though it may not feel especially punchy due to the 250W motor power. The above-average torque of 85Nm should offer decent support for inclines, but riders looking for more aggressive acceleration may find it less responsive. For most trail conditions, the motor should be adequate, but it may struggle on very steep or technical climbs.
Does the bike handle rough terrain comfortably?
This mountain bike is designed for trail riding and should handle rough terrain comfortably, thanks to its suspension system and hydraulic disc brakes, which provide confident control over varied trails. The 250W motor offers smooth support rather than aggressive acceleration, making it suitable for most off-road conditions but less punchy when climbing steep inclines. With a high battery capacity and removable design, it's well-suited for longer rides, though the weight may make it slightly harder to lift or carry when needed.
Is the battery capacity enough for extended trail use?
The 800 watt-hour battery should provide enough range for most extended trail rides, especially given the bike's high range rating of 75 miles. This capacity, combined with the removable battery design, makes it convenient to charge and store the battery separately, which is helpful for multi-day trips or when you need to recharge quickly. However, battery efficiency is average for this type of e-bike, so you may want to plan charging stops if you're riding particularly long or demanding trails.
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 bike's overall weight might make it a bit more challenging to lift or carry when the battery is installed.
Is this bike good value for its price compared to similar mountain e-bikes?
This bike offers a strong balance of features for its price, especially with its high battery capacity and removable design, which is great for trail use and charging convenience. However, the 250W motor and relatively slow charging time may be a drawback for riders who prioritize quick acceleration or frequent charging. While it's well-suited for most trail riding, buyers looking for more powerful motor performance or faster charging might find better options in the same price range.
How does the weight of the bike affect its portability and handling?
The bike's weight of 26.2 kg makes it somewhat heavier than average for a mountain e-bike, which can make lifting or carrying it more challenging, especially when moving it between trails or storing it. However, this weight is typical for a full-suspension mountain bike and should not significantly impact handling on trails, as the suspension and frame design are built to manage rough terrain effectively.
What are the main limitations of this bike for serious off-road enthusiasts?
This bike is well-suited for off-road riding, but serious enthusiasts may find its 250W motor less punchy when accelerating or tackling very steep climbs. While the torque is above average, the low power-to-weight ratio and slower charging time could be limitations for frequent or long-distance riders. The weight of the bike, while typical for a mountain e-bike, may also make it slightly harder to lift or maneuver in tight trail conditions.
