Brompton Electric C Line - High Bar with Roller Rack - E-Motiq review

Where the Electric C Line - High Bar with Roller Rack - E-Motiq fits

The clearest match is taller riders and commuters who want a relaxed position, a compact fold and easy folded rolling rather than the lowest possible carrying weight. 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 Rear Wheel/Motor: Brompton rear motor (24 Nm of torque and 250 W motor power) in rear wheel.. The accessible listing does not identify the controls precisely.

The 250W rear motor supplies a quoted 24Nm and is controlled by a torque sensor, so assistance should respond to how firmly the rider pedals rather than arriving as a fixed surge. It is designed for city starts, headwinds and ordinary gradients, not to mimic the climbing force of a full-size Bosch mid-drive.

Moving the motor to the rear wheel distinguishes this e-Motiq build from the earlier front-drive Electric C Line. That layout should feel more conventional under acceleration, while the handlebar control adds mode selection, start assistance and adaptive range information without requiring a phone for routine operation.

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 conditions).. The result is a natural ride feel with an effortless boost when you need it most — up to 90 km of range from the 345 Wh battery.

The removable 345Wh battery is appreciably larger than the previous 300Wh Brompton pack, and Brompton quotes up to about 90km. That is a best-case figure: rider mass, repeated stops, hills, wind, temperature and higher assistance modes can reduce it substantially.

Removal is useful for charging away from the bike and can take weight off before lifting. Buyers should still plan journeys around a realistic personal range, especially because a small-wheeled folder is often used for stop-start travel where energy consumption is less predictable.

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 Hand-built with Brompton’s iconic all-steel frame, the C Line folds down in seconds to a compact package that’s easy to roll, store, or take anywhere thanks to the SuperRoll+ system.. Fork and suspension details are Rigid fork: Steel.. The tyres are 16″ Schwalbe Marathon Racer..

The high bar creates the most upright of the two C Line positions, easing pressure on the hands and giving a good view in traffic. The trade-off is a less direct, less aerodynamic feel than the otherwise similar mid-bar version.

Sixteen-inch Marathon Racer tyres preserve Brompton’s quick steering and tiny folded footprint, while the steel frame adds a degree of resilience. Four gears and a 163% range are adequate for mostly urban routes with electrical help, but riders facing very steep roads or frequent battery-off riding may prefer broader gearing.

Brakes, transmission and everyday equipment

The bike uses Brompton dual-pivot caliper brakes.. Transmission is Brompton 4-speed derailleur shifter; Brompton chain-pusher derailleur; 11-18 Tooth.. The equipment information is Included; Standard.

Mudguards, the front carrier adaptor and SuperRoll+ rack make this a well-developed mixed-mode commuter. Its great practical advantage is not that 17.9kg is light, but that the bike can be folded into a locked package and rolled on four support wheels.

Dual-pivot rim brakes are simple and familiar but offer less wet-weather reserve than hydraulic discs. Prospective owners should practise the fold, test how the high bar fits their reach and confirm that their intended train operator or storage space accepts the folded dimensions.

What the published evidence tells us

Evans listed this build at £2,779–£3,079 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 motor, battery, gearing and weight statements come from the Evans listing and Brompton’s current e-Motiq product page. Independent long-term evidence for this exact high-bar e-Motiq configuration remains limited because it is a newer system.

Established reviews of the Electric C Line consistently value the exceptionally compact fold and useful urban ride, while also highlighting premium pricing, meaningful carrying weight and the distinctive feel of small wheels. Reviews of the older front-drive model should not be treated as direct evidence of this rear-drive version’s motor behaviour.

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: Very compact, proven Brompton fold
• Advantage: Natural-feeling torque-sensed rear assistance
• Advantage: SuperRoll+ rack improves folded mobility
• Advantage: Relaxed high-bar riding position
• Disadvantage: 17.9kg is still demanding to carry upstairs
• Disadvantage: Four-speed range is narrower than the 12-speed model
• Disadvantage: Rim brakes lack the wet-weather margin of discs
• Disadvantage: Premium price for modest motor torque

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.

Choose this version when comfort and rolling the folded bike matter more than a sporty posture or minimum weight. It is a particularly coherent rail-and-ride commuter, provided four gears suit the route and the owner is realistic about quoted range.
