Overview
This Cube mountain bike is built for trail riding, with front and rear suspension that smooths out rough terrain and hydraulic disc brakes that offer confident stopping power. The 250W motor with torque and cadence sensing provides smooth, controlled assistance, though it lacks the punch needed for steep climbs or rapid acceleration. While the bike makes good use of its 400Wh battery for a reasonable range, the 6.5-hour charge time and relatively low capacity may be a drawback for longer rides. Its carbon frame and overall build quality make it a solid choice for off-road enthusiasts who prioritize trail control over extended range or quick charging.
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 assistance make it a good fit for riders who value natural effort-to-power feedback, while the front and rear suspension should help keep things comfortable on uneven surfaces. The hydraulic disc brakes also provide confidence when stopping, which is important for off-road riding. Riders looking for a capable mountain e-bike that feels stable and predictable on trails may find this model particularly appealing.
Who Should Avoid It
×

At £7,999, this e-bike sits at the higher end of the price spectrum for mountain e-bikes from 2025, and the cost feels notably demanding when compared with similar models from the same year. It offers solid strengths in efficiency, with a well-managed battery and torque-sensing assistance that should make the riding feel more natural, while the front and rear suspension, along with hydraulic brakes, provide a stable and confident ride on rougher trails. However, some similar e-bikes may offer a larger battery, more range, or stronger climbing support, which could be important for riders tackling more challenging terrain. For a mountain e-bike, the trade-off here seems to be between a lighter, more efficient design and the potential for greater range or power. Riders who prioritise comfort, control and a balanced trail experience over maximum range or climbing strength may find the value more compelling. The price is easier to understand if the focus is on everyday trail use rather than long-distance or high-intensity off-road adventures.

Motor Name
Bosch Performance Line SX (Smart System)
This mountain e-bike offers a legal-style pedal assist that feels smooth and predictable, with a focus on natural response through torque and cadence sensing. Next to similar trail-focused models, it provides more modest climbing support and less outright motor punch, which may mean steeper climbs require more rider effort. The motor should feel reasonably lively for its weight, though some similar e-bikes may feel more dynamic under acceleration. The assistance should be well-balanced for trail riding, with predictable control and efficient battery use, making it a good fit for riders who prioritize smooth, controlled trail performance over maximum power.
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, thanks to its front and rear suspension that improves comfort on rough terrain and hydraulic disc brakes that offer reliable stopping power. However, the 250W motor and 400Wh battery may limit performance on longer rides or steep climbs, as the range is on the lower side for extended off-road use.
How does the motor perform when climbing steep trails?
The motor provides smooth and controlled assistance, but it may struggle with very steep climbs due to its 250W power and 60Nm torque, which are on the lower end for mountain bikes. You'll likely need to pedal more actively on steep trails, especially if the terrain is rough or technical. The motor's performance is adequate for moderate climbs but may not offer the punch needed for sustained or very steep ascents.
Does the bike offer enough range for regular mountain biking trips?
The bike offers a range of 45 miles on a single charge, which should be sufficient for most regular mountain biking trips, especially on moderate trails. However, if you frequently ride longer distances or tackle more demanding terrain, you may need to plan for additional charging stops. The 400Wh battery is efficient for the bike's size, but its lower capacity compared to similar models might limit range for extended rides.
How comfortable is the bike on rough terrain and uneven trails?
The bike should handle rough terrain and uneven trails reasonably well, thanks to its front and rear suspension, which should help absorb shocks and improve comfort. However, the low motor power and torque may limit how much assistance you get when navigating particularly challenging trails, so you may need to rely more on your own effort for steep or technical sections.
Is the battery efficient enough for typical mountain biking use?
The battery should provide reasonable efficiency for typical mountain biking use, offering a range of 45 miles on a single charge. However, the 400Wh capacity is on the lower side for extended rides, and the 6.5-hour charge time may be a consideration for frequent riders. While it's efficient for shorter or moderate trails, longer or more intense rides may require careful planning around charging.
How practical is this bike for daily use and charging?
This bike is well-suited for daily off-road use, especially on trails and rough terrain, thanks to its suspension and braking system. However, the non-removable battery means you'll need to charge it at home or a fixed location, which may be less convenient for frequent or long-distance use. The 400Wh battery provides a reasonable range for most mountain biking trips, but the 6.5-hour charge time could be a consideration if you need to recharge quickly.
Is this bike good value for its performance and features?
This bike offers a solid mix of trail-ready features like hydraulic disc brakes, suspension, and smooth motor assistance, but its value depends on your priorities. The 250W motor and 400Wh battery are adequate for casual trail riding, but the slower charging time and lower range may be a drawback for more frequent or longer rides. At £7999, it's a premium option that leans toward comfort and control rather than outright performance, making it a good fit for off-road enthusiasts who prioritize build quality over extended range or quick charging.
What are the main limitations of this bike for serious off-road riding?
This bike is designed for trail riding, but it may struggle with very steep climbs or rapid acceleration due to its lower motor power and torque. The 400Wh battery provides a reasonable range for most off-road trips, but the longer charge time and lower capacity could be inconvenient for frequent or extended use. While the hydraulic disc brakes and suspension offer good control and comfort on rough terrain, the overall performance is better suited for moderate off-road trails rather than intense or technical mountain biking.
