Compared with similar mountain bike e-bikes on Bikkerr, this model sits £1,340.93 above average
The Giant Reign E+ 1 is listed at £6,999, which feels higher than many similar mountain e-bikes from 2024, especially when considering the weight and power output. It offers a strong battery capacity and range that compare well with rivals, and the torque support feels well-suited for off-road use, which is a key consideration for this type of bike. However, some similar models may offer a more responsive ride for their weight, which could be important for riders prioritising agility. For a mountain e-bike focused on trail comfort, battery efficiency and braking performance, the value case is clearer, though buyers should weigh whether the price aligns with their expectations for a bike of this weight and power. Riders looking for a reliable, long-range mountain e-bike with strong braking and suspension may find the price justified, but those seeking a lighter, more dynamic ride might find the trade-off less appealing.

Motor Name
Giant Sync Drive Pro 2 (powered by Yamaha)
This mountain e-bike offers a balanced motor assistance that feels natural and predictable, with strong torque support for climbing and low-speed trail riding. Next to similar models, it provides a smooth and controlled power delivery, though some e-bikes in the same category may feel more punchy or lively for their weight. The motor should help with climbing and rough terrain, though it may not deliver the same level of acceleration or outright power as some competitors. With torque and cadence sensing, the assistance should feel responsive and well-tuned for trail riding, allowing riders to adjust effort naturally. This motor setup is likely to suit riders looking for reliable, efficient support on trails without expecting the most aggressive motor 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?
The Giant Reign E+ 1 is well-suited for long off-road rides, thanks to its high battery capacity and efficient range, which should keep you riding for extended periods without needing to recharge. The mountain bike design and suspension comfort make it a solid choice for trails and rough terrain, though its lower motor power and heavier weight may make steep climbs slightly more challenging and the bike harder to lift.
How does the motor perform when climbing steep trails?
The motor provides smooth and controlled assistance, but its 250W power and above-average weight may make steep climbs feel less punchy. While the above-average torque helps with traction, you may need to pedal more actively on very steep trails. This bike is better suited for moderate climbs rather than extremely steep terrain.
Does the bike handle rough terrain comfortably?
The Giant Reign E+ 1 is built for off-road use and should handle rough terrain comfortably, thanks to its mountain bike design and smooth power delivery. The high battery capacity and efficient range make it suitable for longer rides, and the removable battery adds convenience for charging. However, its heavier weight and lower motor power may make it slightly less agile on very technical trails or steep climbs, so it's best suited for riders who prioritize endurance and battery life over lightweight performance.
Is the battery capacity enough for extended mountain biking sessions?
The Giant Reign E+ 1 has a high-capacity battery that should support extended mountain biking sessions, especially with its efficient range of 95 miles. This makes it a good option for longer trail rides without needing to recharge frequently. However, the motor power is on the lower side for this type of bike, which may affect performance on very steep climbs, so riders should consider this when planning their routes.
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 feature also makes it easier to store the battery separately when not in use, helping to keep your bike lighter and more manageable for transport or storage. However, since the battery is high capacity, it may take longer to charge compared to smaller batteries on similar e-bikes.
Is this bike good value for its price compared to similar e-bikes?
The Giant Reign E+ 1 offers strong off-road performance with reliable battery efficiency for longer rides, but its price point might be a factor for buyers looking for more budget-friendly options. While it has a high-capacity battery and excellent range, the motor power is on the lower side compared to similar e-bikes, which may affect acceleration and hill climbing. Its weight is also above average, which could make it less convenient to carry or lift, especially for those who need to transport it frequently. Overall, it's a solid choice for trail riding, but buyers should consider whether the features justify the cost compared to other mountain e-bikes in the same price range.
How does the weight of the bike affect its portability and handling?
The Giant Reign E+ 1 weighs 26.4 kg, which is above average for a mountain bike. This makes it slightly heavier to carry, especially when lifting it onto a vehicle or carrying it over obstacles. However, the weight is well-distributed and should not significantly impact handling on trails, as the bike is designed for off-road use. The added weight may feel more noticeable on steep climbs or when maneuvering through tight sections, but it's balanced by the bike's stability and robust build for rough terrain.
What are the main limitations of this e-bike for serious mountain bikers?
The Giant Reign E+ 1 is a mountain bike, but it may not be the best choice for serious mountain bikers who prioritize steep climbs or high-speed trail performance. Its 250W motor, while adequate for general trail use, may feel underpowered on very steep or technical climbs. Additionally, the bike's weight of 26.4 kg could make it harder to carry or maneuver in challenging terrain. While it offers a good range and efficient battery, serious riders looking for maximum power and agility might find these limitations impactful on more demanding trails.
