Overview

The CUBE AMS HYBRID ONE44 C:68X SLT 400X is a mountain bike designed for trail riding and rough terrain, offering a smooth and controlled assistance feel thanks to its torque and cadence sensor. With front and rear suspension, it provides good comfort on uneven surfaces, though its 250W motor and 60Nm torque may feel less punchy when climbing steep hills or accelerating quickly. The bike makes good use of its 400Wh battery for a reasonable range, but the 6.5-hour charge time and lower battery capacity could be a consideration for longer rides. Its carbon frame and hydraulic disc brakes add to a solid riding experience, though it's best suited for trail use rather than urban commuting or heavy cargo hauling.

Best For

✓

This mountain e-bike should suit riders who enjoy trail riding and want a balance of comfort and control on rougher terrain. Its smooth power delivery and responsive torque sensor make it a natural fit for riders who value assistance that matches their effort, while the front and rear suspension should help keep things comfortable on uneven surfaces. The hydraulic disc brakes add confidence when stopping, making it a solid choice for riders who prioritize braking performance on trails.

Who Should Avoid It

×

Riders seeking stronger hill-climbing performance or longer range may want to compare alternatives, as this bike has lower torque and battery capacity compared to similar mountain e-bikes. Riders who need faster charging times or more aggressive trail performance could find stronger options in the same category. However, the bike still offers smooth power delivery and good off-road comfort for riders prioritizing natural assistance and controlled riding experiences.

At £7,499, this e-bike sits at the higher end of the price spectrum when compared with similar mountain e-bikes from 2025, and the value case depends on what you prioritise. It offers solid off-road performance with front and rear suspension, hydraulic disc brakes, and torque-sensing assistance that should feel natural on varied terrain, which is a strong point against many rivals. However, some similar e-bikes may offer more range, a larger battery, or stronger climbing support, which could be important for riders tackling more demanding trails. For this type of mountain e-bike, the trade-off seems to be between a lighter, more responsive frame and a slightly smaller battery, which may affect range for longer rides. Riders who prioritise agility, comfort on rough terrain, and a well-balanced package may find the price justified, but those needing extended range or heavier climbing support might find more value elsewhere.

We reach this value score by combining the bike’s price, specification, performance data and comparison against similar e-bikes in our database.

Motor Name

Bosch Performance Line SX Smart System

This mountain e-bike offers a legal-style pedal assist that feels more modest in climbing support compared to some trail-focused rivals, making it better suited for moderate trails than steep ascents. Next to similar models, it provides a smoother and more predictable assistance feel thanks to its torque and cadence sensor, though some e-bikes may offer more immediate power for quick acceleration or steeper climbs. The motor should help with loaded riding and rough terrain, but riders may find it asks for more effort on steep sections or when pushing harder. The combination of torque sensing and efficient battery use should make the assistance feel natural and well-controlled, though the motor’s power-to-weight ratio suggests some similar e-bikes may feel more lively for their size. This setup is likely to suit riders looking for a balanced trail e-bike that prioritises efficiency and control over maximum punch.

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 off-road trails and rough terrain, thanks to its front and rear suspension, which improves comfort on uneven surfaces. However, its 250W motor and 60Nm torque may feel less powerful when climbing steep hills or accelerating quickly, which could be a consideration for longer or more demanding rides.

How does the motor perform when climbing steep trails?

The motor may feel less responsive when climbing steep trails, as the 250W power and 60Nm torque are on the lower end for mountain e-bikes. While it should provide smooth and controlled assistance for moderate inclines, riders tackling very steep or technical trails may find they need to put in more effort, especially on longer climbs. The bike's suspension and braking should help manage the terrain, but the motor's performance might not be as punchy as higher-powered models in this category.

Does the bike offer enough range for extended mountain biking sessions?

The bike offers a range of 45 miles, which should be sufficient for most mountain biking sessions, but may be limiting for very long or extended rides. The 400Wh battery is on the lower side for e-bikes in this category, so riders planning multi-day trips or long trail sessions may need to plan for additional charging or battery swaps. However, the bike's efficiency and smooth power delivery help make the most of its battery capacity for typical trail use.

How comfortable is the bike on rough and uneven terrain?

The CUBE AMS HYBRID ONE44 C:68X SLT 400X is designed with front and rear suspension, which should help absorb shocks and improve comfort on rough and uneven terrain. While the bike offers good rough-road comfort, its 250W motor and 60Nm torque may not provide the strongest acceleration or hill-climbing punch, which could affect performance on very technical trails. However, for most trail riding and uneven surfaces, the suspension and overall design should provide a smooth and controlled ride experience.

Is the braking system reliable for high-speed off-road use?

The hydraulic disc brakes on this mountain bike should provide confident stopping power even at higher speeds on rough terrain. They are well-suited for off-road use, where control and reliability are important. However, braking performance can also depend on factors like tire grip, trail conditions, and how aggressively you ride, so it's always good to ride within your limits and maintain your brakes regularly.

How does the battery efficiency compare to similar e-bikes?

The battery efficiency of this e-bike is strong for its category, offering a decent range of 45 miles on a single charge. However, its 400Wh battery capacity is on the lower side compared to similar mountain e-bikes, which may impact longer rides. The bike's efficiency is supported by its ability to make good use of the battery, but the 6.5-hour charge time could be a drawback for riders who need quick turnaround between rides.

Is this bike a good value option compared to other mountain e-bikes?

This bike offers a solid set of features for trail riding, including good suspension, reliable braking, and smooth power delivery. However, its lower motor power, torque, and battery capacity may limit performance on demanding trails or longer rides compared to more powerful models. At its price point, it's a reasonable option for casual to moderate trail use, but serious off-road riders may find better value in bikes with higher power and longer range.

What are the main limitations of this bike for serious off-road riders?

This bike is designed for trail riding and rough terrain, but it may struggle with very steep climbs or fast acceleration due to its 250W motor and 60Nm torque, which are on the lower end for serious off-road use. The 400Wh battery provides a reasonable range, but the 6.5-hour charge time and lower capacity could be inconvenient for longer rides. While the hydraulic disc brakes offer good stopping power, the overall performance may not match more powerful e-bikes designed for extreme off-road conditions.
