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

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

The clearest match is frequent rail commuters who want the lighter P Line chassis, a responsive posture and easy folded rolling. 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.

Brompton’s 250W rear-hub e-Motiq drive measures rider input through a torque sensor and supplies assistance accordingly. The control screen adds start assistance and live range information, making the system easier to manage in stop-start traffic than a battery-mounted control alone.

Independent review of the current P Line describes assistance as smooth, immediate and effective on normal urban hills. Its purpose is to preserve a bicycle-like response in a compact package; the modest hub torque is not designed for carrying cargo up sustained mountain gradients.

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 345Wh removable battery is quoted at up to 90km in favourable conditions. It offers useful commuting headroom, but range should be treated as a variable outcome rather than a specification that every rider will reproduce.

A removable pack is particularly valuable on a folding bike because it can be charged at a desk and detached before a lift. Smart prediction may improve after the first 100km of use, though real-world weather and route changes still need a reserve.

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..

The mid bar gives a more engaged posture and a little more front-wheel authority than the high option. Some riders will find it quicker and more natural; others will prefer the high bar’s reduced hand and back loading, making a fit check worthwhile.

Continental Contact Urban tyres and 16-inch wheels make the bike brisk to accelerate and responsive in tight streets. The four-speed, 163% drivetrain is clean and easy to operate but is the clear limiting factor for steep unassisted riding.

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..

At a quoted 16.2kg including battery, this is lighter to handle than the all-steel C Line, and the SuperRoll+ system reduces how often it needs lifting at all. Mudguards, luggage compatibility and quick-release pedals complete a strong train-and-office package.

The compactness comes with small-wheel sensitivity to broken roads and caliper brakes rather than discs. Owners who prioritise rough-surface stability and braking reserve should compare the heavier G Line instead of assuming the P Line is automatically superior.

What the published evidence tells us

Evans listed this build at £3,499–£3,879 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.

The Evans listing and Brompton’s official SuperRoll+ page agree on the central hardware, including the mixed-material frame, four gears and 345Wh system. Weight and maximum range remain manufacturer figures subject to configuration and conditions.

Current independent P Line testing is broadly positive about motor smoothness, portability and ride quality, but also identifies price and the technique required to master the fold. The test applies closely to the shared platform, although handlebar choice changes posture.

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: Relatively light for a complete electric folder
• Advantage: Direct and lively mid-bar handling
• Advantage: Current rear-drive e-Motiq system
• Advantage: Excellent folded rolling arrangement
• Disadvantage: Premium price
• Disadvantage: Four gears restrict unassisted versatility
• Disadvantage: Rim brakes rather than discs
• Disadvantage: Mid bar may not suit comfort-first riders

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.

The mid-bar P Line e-Motiq is arguably the most coherent performance-commuter Brompton here: lighter than C Line, easier to roll than a rackless build and more natural under power than the former front-drive system. Choose the high bar instead if posture, not agility, is the priority.
