Overview
The Orbea DIEM 20 2024 is a versatile all-terrain e-bike that balances everyday practicality with decent hill-climbing support, making it a solid choice for mixed-surface riding. Its 600W motor with 85Nm of torque provides strong assistance, especially on inclines, while the efficient 630Wh battery delivers a useful range for most daily commutes or light adventures. Hydraulic disc brakes offer confident stopping power, and the belt drive system adds to its low-maintenance appeal. However, the lack of suspension means rough roads and potholes can feel harsh, and the non-removable battery means charging requires access to a power source near the bike. At 25.5kg, it's heavier than some rivals, which might make lifting it more challenging for some riders.
Best For
✓
This all-terrain e-bike should suit riders looking for a versatile option that handles mixed surfaces and offers reliable performance for everyday use, including light off-road trails. Its strong motor and above-average range for this type of e-bike make it a good choice for those prioritising hill climbing and longer rides without frequent recharging. The hydraulic disc brakes and solid power-to-weight ratio also support confident braking and responsive assistance, which is especially useful for riders who carry heavier loads or need predictable control in varied conditions.
Who Should Avoid It
×
Riders who prioritise off-road performance or need a more rugged suspension system may be better served by a different e-bike. The lack of suspension could make rough trails or uneven paths feel less comfortable compared to similar all-terrain bikes with suspension. Additionally, the non-removable battery may be a drawback for riders who need the flexibility to charge the bike away from home or work. However, the bike still offers strong hill support and a good power-to-weight ratio, making it a solid choice for mixed-surface riding and commuting.

This all-terrain e-bike offers a strong and responsive motor setup that should feel capable and lively on a variety of surfaces. Against similar e-bikes, the motor's power and torque should provide good support for climbing and low-speed terrain, though it may not match the most aggressive trail-focused models. The motor should assist well with hills and loaded riding, and the torque and cadence sensor should help balance natural response with predictable assistance. The power-to-weight ratio should make the assistance feel more lively in real riding, and the motor's efficiency should support longer rides without sacrificing performance. Riders looking for a versatile all-terrain e-bike with solid hill support and efficient battery use should find this motor setup 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 rides on mixed terrain?
The Orbea DIEM 20 2024 is well-suited for long rides on mixed terrain, thanks to its 600W motor with 85Nm of torque, which provides strong assistance on inclines and varied surfaces. The 630Wh battery offers a range of around 75 miles, which should cover most daily commutes or light adventures. However, the lack of suspension may make rough roads or potholes feel harsh, and the non-removable battery means you'll need to charge it near a power source.
How does the motor perform when climbing steep hills?
The motor should handle steep hills confidently, thanks to its above-average torque and power for an all-terrain e-bike. This means you'll get strong support when climbing, especially with the torque and cadence sensor helping deliver assistance when you need it most. While the power delivery may not feel perfectly smooth in all situations, the motor's strength should make steep climbs more manageable.
Is the battery efficient enough for daily commuting or regular use?
The battery efficiency of the Orbea DIEM 20 2024 is above average for similar all-terrain e-bikes, offering a range of 75 miles on a single charge, which should be sufficient for daily commuting or regular use. The 630Wh battery capacity also contributes to this strong range, though the battery is not removable, meaning you'll need to charge the bike near a power source. With a charging time of 4 hours, which is faster than average for this type of e-bike, it should be convenient for most users.
How comfortable is this bike on rough or uneven roads?
This bike may feel less comfortable on rough or uneven roads due to the lack of suspension, which can make potholes and bumps more noticeable. However, the 29-inch wheels and Vittoria e-Randonneur tires should help absorb some of the impact and provide decent grip on mixed surfaces. For all-terrain use, it's best suited for moderate conditions rather than extremely rough or technical paths.
Is this bike good value for the price compared to similar e-bikes?
This bike offers strong value for the price, especially considering its above-average motor power, torque, and battery efficiency for an all-terrain e-bike. The 75-mile range and 630Wh battery are competitive, and the hydraulic disc brakes provide confident stopping power. However, the price is on the higher side compared to similar models, so buyers should weigh the performance benefits against the cost.
What are the main limitations or trade-offs of this bike?
The main limitations of this bike include its non-removable battery, which means you'll need to keep the whole bike near a power source to charge it. It's also heavier than average for its type, making it a bit harder to lift, and the frame doesn't fold, so storage depends on the bike's size and weight. These factors might be important if you need to carry or store the bike frequently.
How practical is this bike for everyday ownership and storage?
The Orbea DIEM 20 2024 is reasonably practical for everyday ownership, with a range of 75 miles and a 630Wh battery that should support regular use. However, the non-removable battery means you'll need to keep the whole bike near a charging point, which may be less convenient for some. At 25.5kg, it's heavier than average for an all-terrain e-bike, so it may be harder to lift or store in small spaces. The bike doesn't fold, so storage will depend on available space, but its low-maintenance belt drive should reduce ongoing upkeep.
Who is this bike best suited for, and who might find it less ideal?
This bike is best suited for riders who need a reliable all-terrain e-bike for daily commuting, light off-road trails, or mixed-surface riding. It offers strong hill climbing support, good braking confidence, and a range that should handle most regular use cases. However, it may be less ideal for those who need a removable battery for convenience or who frequently ride in very remote areas without easy access to charging points.
