Brompton Electric P Line 4-speed - Mid Handlebar review

Where the Electric P Line 4-speed - Mid Handlebar fits

The clearest match is city commuters considering a discounted or readily available P Line who prioritise low folded weight and compactness over the latest electrical system. This review is based on the Evans specification, manufacturer information and clearly identified independent coverage; it is not presented as a RideIn hands-on test.

Motor, controls and UK legality

The accessible Evans listing does not identify the motor precisely. The exact motor, display and control configuration should be established before purchase.

The 250W front hub is driven by cadence and torque information from the bottom bracket and assists to 25km/h. Road tests of this generation generally found it powerful enough for city hills and responsive, although some testers reported occasional surging rather than the most seamless delivery.

Front-wheel drive leaves the four-speed rear transmission independent of the motor and preserves the folding layout. On wet paint, gravel or a sharply turning climb, front traction deserves more care than with the current rear-drive model.

For use as an electrically assisted pedal cycle in Great Britain, the maximum continuous rated motor power must not exceed 250W, assistance must cut out by 15.5mph and the pedals must be able to propel the bike. Check the label and delivered configuration rather than relying on a category name.

Battery, charging and realistic range

The listed battery is 300 Wh 36 V with LED display. Range 20-45 miles (30-70km). 5 V 1.5A USB port to charge portable devices. 4-hour full charge using included 2A charger. Range 20-45 miles (30-70km).

The detachable 300Wh pack is quoted at 30–70km and around four hours for a full charge. Its bag includes a USB port, and one-click removal allows charging away from the bike as well as reducing lifting weight.

The broad claimed range reflects how strongly conditions and mode selection affect a compact battery. Owners should base a commute on their lowest observed winter range, not the top of the marketing window.

Use only the approved compatible charger, charge away from escape routes and stop using a battery that is damaged, swollen, leaking or unusually hot. Ask for the replacement-pack price and warranty conditions before the original battery becomes a problem.

Frame, fit and ride character

The frame specification is Precision drawn heat-treated steel tubing with hand brazing and selected auto-brazed joints. Fork and suspension details are Rigid fork: Reinforced steel brazed fork. The exact tyres should be confirmed on the selected build.

A titanium rear frame reduces mass and the mid handlebar gives an energetic urban position. Reviewers of this generation praise the characteristic nimble Brompton ride, although small wheels and a short wheelbase can initially feel busy to riders coming from full-size hybrids.

The four-speed derailleur is light and straightforward, with ratios chosen for town riding. It cannot match the 12-speed model’s low climbing gears, particularly if the battery is flat or the route extends well beyond the city.

Brakes, transmission and everyday equipment

The bike uses Brompton Dual Pivot Calipers. Transmission is Brompton 4-speed trigger shifter; Patent-pending direct mount 4-speed derailleur. The equipment information is Curved profile with updated mudguard flaps; Chromoly steel tube, centreless ground, chrome plated for hardness, delivered in a standard length, suitable for maximum inside leg 33 inches / 84 cm.

The compact fold, mudguards, battery-powered lighting and removable left pedal make it a convincing train companion. The absence of a roller rack in the title means folded wheeling will not be as effortless as on the SuperRoll+ e-Motiq variants.

Brompton-specific electrical and folding parts make dealer support important. Anyone comparing stock should also confirm the supplied colour-specific pedal, battery bag and warranty position rather than assume every P Line bundle is identical.

What the published evidence tells us

Evans listed this build at £2,999–£3,129 when RideIn checked it on 29 August 2026. Prices can differ by colour or size, and stock can change; a discount against a reference price does not by itself establish value.

Evans provides the exact component list for this front-drive build, while Brompton’s current main range now emphasises e-Motiq. An official renewed-product page confirms the existence and broad format of the earlier Electric P Line, but availability can change.

Road.cc and Cycling News tests of this generation support its strong portability and useful city assistance, while raising specific concerns about price, occasional power surging and some components. Those points should not be attributed to the newer rear-drive P Line.

Advantages and disadvantages

The useful comparison is whether the complete build suits the regular route, storage and service plan. A premium motor cannot compensate for poor fit, while a modest component can be entirely sensible on the right type of bike.

• Advantage: Light mixed-material folding frame
• Advantage: Compact and proven fold
• Advantage: Removable 300Wh battery with USB output
• Advantage: Useful integrated lights and mudguards
• Disadvantage: Earlier front-hub system
• Disadvantage: Only four gears
• Disadvantage: No SuperRoll+ rack in this specification
• Disadvantage: Premium proprietary platform

Buying checks and RideIn verdict

Confirm the exact product code, frame size, colour, battery capacity, assistance configuration and included equipment before paying. Ask which Evans branch or authorised dealer will handle electrical diagnosis, warranty labour and replacement components, then test the brakes, controls and fit before committing to regular use.

This remains a capable electric folder when its price reflects the previous-generation drive. Compare it carefully with the e-Motiq P Line: the older bike may save money, but the newer system and SuperRoll+ package are meaningful functional upgrades.
