Overview
The Ribble Endurance SL e - Pro is a lightweight, carbon-framed road e-bike designed for paved routes, offering smooth motor support and efficient range for long rides. With a 250W motor and 65Nm of torque, it provides controlled assistance that feels lively for its weight, though it lacks the punch of more powerful models. Hydraulic disc brakes offer confident stopping power, and the bike's efficient battery use delivers a respectable range for the size. However, the battery isn't removable, which means charging requires the whole bike to be near a power source, and the charging time is notably slow compared to similar bikes.

This road e-bike offers a smooth, efficiency-focused assistance that feels closer to a traditional road bike, with a legal-style pedal assist system that prioritises range and low weight. Against similar e-bikes, its cadence-sensing motor should provide straightforward support, though it may feel less refined than torque-sensing systems on the market. The strong torque and power-to-weight balance should help with climbing and acceleration, making it a solid choice for riders who want a natural ride feel without sacrificing hill support. The cadence sensor may offer simpler control, but it might not be as responsive as torque-based systems, especially in technical or variable riding conditions. Riders looking for a lightweight, efficient road e-bike with good range and a traditional feel should find this motor setup a good match for 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 paved roads?
This bike is well-suited for long rides on paved roads, thanks to its efficient battery use and smooth motor support. With a range of 87 miles, it should handle extended trips comfortably, though the lower battery capacity and slow charging time may require careful planning for longer rides. The lightweight frame and hydraulic disc brakes also contribute to a stable and controlled ride over long distances.
How does the motor feel when climbing hills?
The motor provides decent support when climbing hills, especially with its above-average torque for this type of e-bike. However, the motor power is below average, which may mean you'll need to pedal more actively on steeper inclines. The cadence sensor activates assistance based on your pedaling speed, so maintaining a steady rhythm can help maximize the motor's effectiveness on hills.
Does the bike still feel like a traditional road bike with the motor assistance?
The bike retains a traditional road bike feel with the motor assistance, as the frame and geometry are designed for paved-road riding. The motor provides smooth support, though it may not be as refined as torque-sensing systems due to the cadence sensor. With 65 Nm of torque, it should handle hills reasonably well, but the 250W motor is on the lower side for this type of e-bike, which may affect acceleration.
Is the battery efficient enough for everyday commuting or longer rides?
The bike offers a range of 87 miles, which is above average for similar e-bikes, making it suitable for everyday commuting and longer rides on paved roads. However, the battery capacity is below average, and the charging time is relatively slow at 6 hours, which may be a consideration for frequent or long-distance riders. The battery is not removable, so charging requires the bike to be near a power source, which may affect convenience for some users.
How practical is this bike for daily use, especially with its charging time and battery size?
This bike offers a good balance of range and weight, making it practical for daily use on paved roads. However, the battery capacity is below average for similar e-bikes, and it takes around 6 hours to charge, which is slower than many competitors. Since the battery isn't removable, you'll need to keep the whole bike near a power source to recharge, which may be less convenient for some users.
Who is this bike best suited to, and what are its main compromises?
This bike is best suited to experienced road cyclists who prioritize a natural ride feel, good braking confidence, and a strong power-to-weight ratio for climbing. Its main compromises include a lower battery capacity and slower charging time compared to similar e-bikes, which may limit range and convenience for frequent or long-distance riders. The non-removable battery also means charging requires access to a power source near the bike, which could be less practical for some users.
Is this bike good value compared with similar e-bikes in its category?
This bike offers good value for a road e-bike, especially considering its strong range and efficient battery use. While the battery capacity is lower than some competitors, the range is above average, which means you can ride longer without frequent recharging. The price is in line with similar models, and the bike's performance, including its power-to-weight ratio and braking confidence, supports its value proposition for paved-road riding.
How does the power delivery and motor performance compare to other road e-bikes?
The motor provides smooth support for road riding, but its power is below average for similar e-bikes, which may affect acceleration and climbing steeper hills. However, the high torque helps with hill climbing, and the power-to-weight ratio is strong for this type of bike. The cadence sensor offers usable assistance, though it may not be as refined as torque-sensing systems on other road e-bikes.
