Brompton Electric P Line 4 Speed - High Handlebar Roller Rack - E-Motiq review

Where the Electric P Line 4 Speed - High Handlebar Roller Rack - E-Motiq fits

The clearest match is taller or comfort-focused mixed-mode commuters prepared to pay more for a lighter electric Brompton and a relaxed high-bar position. 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

Evans lists Custom-designed rear hub motor (part of the e-Motiq system) by Brompton.. The accessible listing does not identify the controls precisely.

The rear e-Motiq motor is tuned for smooth, proportional urban assistance rather than headline torque, with a sensor measuring pedal effort and the handlebar unit controlling modes. Current independent testing describes the system as prompt and impressively smooth on climbs within the limits of a compact folding bike.

Because the motor is in the rear wheel, power delivery feels more conventional than on the former front-drive P Line. Its 24Nm class of output is enough to reduce effort on ordinary city gradients, but riders expecting full-size mid-drive shove under heavy loads should test it on a representative hill.

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 345 Wh “Greenway” battery, removable, up to approx. 90 km range (depending on assist level, terrain and rider weight).. 90 km range (depending on assist level, terrain and rider weight).

The removable 345Wh e-Motiq battery carries a headline range of up to 90km. This is a useful capacity increase over the former 300Wh pack, although high assistance, low temperatures and fast stop-start riding will shorten real distance.

Removing the battery for charging or carrying also improves the bike’s handling off the ground. The adaptive range display should become more personalised over its first rides, but it cannot eliminate the effect of an unexpectedly windy or hilly route.

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-brazed joints and selected auto-brazed joints.. Fork and suspension details are Rigid fork: Carbon fibre.. The tyres are 16″ size, Continental Contact Urban tyres..

A high handlebar places the rider more upright than the otherwise near-identical mid-bar model. That supports visibility and comfort, while the carbon fork and Continental Contact Urban tyres aim to take some edge off the firm, quick 16-inch-wheel ride.

Four gears spanning 163% are deliberately simple and appropriate for assisted city riding. They are less convincing for prolonged unassisted use in very hilly areas, so buyers should compare the route requirement rather than assume the premium frame automatically makes this the most versatile P Line.

Brakes, transmission and everyday equipment

The bike uses Brompton Dual-Pivot caliper brakes front and rear.. Transmission is Brompton 4-speed derailleur shifter; Brompton chain-pusher derailleur; 11-18 tooth cassette.. The equipment information is Square taper..

Evans quotes a starting weight of 16.2kg including the battery, a meaningful reduction beside the steel C Line. SuperRoll+ gives four-point support when folded, while quick-release pedals, mudguards and the front luggage interface suit rail travel and small homes.

The P Line’s lighter rear frame and carbon fork raise purchase and replacement costs. Its folded dimensions in the Evans specification are also larger than the quoted C Line dimensions, so anyone buying for a precise locker or luggage space should verify fit rather than rely on the Brompton name alone.

What the published evidence tells us

Evans listed this build at £3,499 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 and Brompton document the exact high-bar e-Motiq hardware, weight and battery claim. The high and mid variants share most equipment, meaning independent P Line tests are useful for the platform even where the reviewed handlebar or colour differs.

Cycling Weekly’s current e-Motiq P Line review supports the themes of smooth assistance, strong hill help, compactness and premium execution, while also stressing its high price and an initial learning curve for the fold. Those findings are more relevant than reviews of the older front-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: Lighter than the equivalent Electric C Line
• Advantage: Smooth e-Motiq rear assistance
• Advantage: Relaxed position for taller riders
• Advantage: SuperRoll+ supports easy folded wheeling
• Disadvantage: Very high purchase price
• Disadvantage: Only four gears
• Disadvantage: Still heavy enough to notice on stairs
• Disadvantage: Premium mixed-material parts may cost more to replace

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 is the high-comfort, lower-carry-effort electric Brompton for people who genuinely use trains, stairs and tight storage. Its premium makes sense only when the weight saving and refined e-Motiq delivery will be used often, not merely admired on the specification sheet.
