Overview
This Brompton Electric P Line with SuperRoll+ is a compact folding e-bike designed for urban commuters who value portability and ease of storage. It offers smooth motor support and efficient range for daily use, making it well-suited for city travel and mixed-mode commuting. However, its rim brakes may feel less confident on descents or in wet conditions, and the motor’s power delivery is modest, which could make climbing steeper hills more effortful. The bike’s lightweight frame and foldable design make it easy to carry and store, though the non-removable battery means you’ll need to charge it at home or work, limiting flexibility for on-the-go charging.
Best For
✓
This folding e-bike should suit riders who prioritize compact storage and portability, especially for urban trips and mixed-mode commuting. Its efficient battery use and strong range for a folding e-bike make it appealing for those who need reliable assistance without sacrificing the convenience of a foldable frame. Riders who value a balance between lightweight design and practical range will find this bike particularly well-suited for daily travel in city environments. It may also appeal to those who occasionally need to transport the bike indoors or use it as part of a multi-modal commute.
Who Should Avoid It
×
Riders who prioritize strong braking confidence or need a removable battery for easy transport may want to compare alternatives. Rim brakes can feel less reassuring on an e-bike, especially in wet conditions or on descents, and the fixed battery may be less convenient for some users. Riders who frequently carry heavier loads or need stronger hill-climbing support might also find stronger-torque options more suitable. However, the bike still offers good range for a folding e-bike and is well-suited for urban commuting and storage-friendly designs.

Motor Name
Custom Brompton e-Motiq brushless rear-hub motor
This folding e-bike offers a smooth and predictable assistance feel that should suit urban riding and short practical journeys, with a legal-style pedal assist system that prioritises control over outright power. Next to similar e-bikes, its support is more modest, focusing on efficiency and natural response rather than aggressive acceleration or heavy climbing punch. The motor should feel reasonably supportive for flatter terrain and everyday use, though it may not provide the same level of low-speed push or hill-climbing assistance as some alternatives. With torque and cadence sensing, the assistance should feel balanced and responsive, especially in city conditions, and the motor’s efficiency helps deliver a strong range for its size. Riders looking for a lightweight, easy-to-handle folding e-bike that prioritises practicality and battery efficiency over high-output performance may 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 daily commuting and folding for transport?
This Brompton Electric P Line is well-suited for daily commuting thanks to its compact design and above-average range of 56 miles, which should cover most urban trips. Its folding frame makes it easy to carry on public transport or store at home, though the non-removable battery means you'll need to charge it at a fixed location. The lightweight build and smooth motor support make it practical for everyday use, but the rim brakes may feel less confident on wet or steep descents.
How does the motor perform when climbing hills or accelerating from a stop?
The motor provides smooth support for climbing hills and accelerating from a stop, but it may feel a bit limited compared to more powerful e-bikes. With 250W of motor power and 30Nm of torque, it should handle moderate inclines and city traffic well, though it may struggle with very steep hills. The torque and cadence sensor helps deliver consistent assistance, making it suitable for everyday use and folding convenience.
What is the real-world range on a single charge for typical city use?
This e-bike offers a real-world range of around 56 miles on a single charge, which should be sufficient for most city commutes and daily use. The range is above average for similar folding e-bikes, meaning you can expect good efficiency from its battery size. However, the battery capacity is below average, so if you need longer trips or frequent charging, you may want to plan accordingly.
How practical is this bike for storage in small spaces or at home?
This Brompton Electric P Line is very practical for storage in small spaces due to its foldable design, which makes it easy to keep indoors or in tight areas. The bike weighs 16 kg, which is below average for similar e-bikes, helping with portability. However, the battery is not removable, so you'll need to charge it at home rather than taking it with you for transport. Overall, it's a great choice for urban storage and commuting needs.
Does the bike have enough power and battery capacity for longer rides?
The bike offers a range of 56 miles on a single charge, which should be sufficient for longer rides, especially in city environments. The 345Wh battery is reasonably sized for a folding e-bike, and the 5-hour charge time makes it convenient for regular use. While the motor power and torque are below average for similar e-bikes, the battery efficiency is strong, meaning you can expect good range for the size of the battery.
How does the braking system perform, especially in wet conditions?
The braking system uses rim brakes, which are generally less confident in wet conditions compared to disc brakes. This can affect stopping power when the roads are slippery, so riders should be cautious and allow extra stopping distance. For a folding e-bike, this is a common tradeoff for its compact design, but it's something to keep in mind if you frequently ride in rainy or damp environments.
Is this bike good value compared to other folding e-bikes in its class?
This bike offers strong value for a folding e-bike, especially if storage and portability are important to you. The range is above average for similar e-bikes, and the foldable design makes it highly practical for urban commuting and transport. However, the price is on the higher side compared to other folding e-bikes in its class, so you may want to consider whether the folding convenience and efficiency justify the cost.
What are the main limitations or trade-offs of this bike?
This bike is well-suited for folding and storage, but there are a few trade-offs to consider. The motor power and torque are below average for similar e-bikes, which may make acceleration and hill climbing feel less responsive. Additionally, the rim brakes, while functional, may not provide the same level of confidence as hydraulic systems, especially in wet conditions or on descents. These factors are important to keep in mind if you frequently ride in challenging terrain or need strong braking performance.
