A lightweight all-road electric platform that rides like a performance bike.

Who is it for?
Why did we build it?
What is it?Luma is a lightweight all-road electric platform that rides like a performance bike. Based on the award-winning Sika, it combines real-world fit, 45mm tyre clearance and discreet MAHLE X20 assistance to extend the ride across rough roads, mixed surfaces and longer days.
Who is it for?Riders who want the feel of a performance road bike, with quiet support when the road, route or rider asks for it. Luma is for longer days, bigger loops, rougher roads and anyone who wants to keep riding further.
Why did we build it?We believed electric assistance could enhance the ride without taking anything away from it. Too often, e-road bikes are shaped by the system before the rider is considered. Luma starts with fit, handling and all-road versatility, then adds discreet support in a way that feels natural, useful and enjoyable.

Key Features

Complete Builds From 10kg

Luma is designed to stay light, responsive and recognisably performance-led. With the MAHLE X20 system adding approximately 3kg, complete builds can start from 10kg without the heavy, dulled-down feel often associated with e-bikes.

Real-World Fit

Like Sika, Luma is shaped around real riders, not extreme race positions. A sensible stack height and balanced geometry make it easier to find a position that feels natural, efficient and sustainable, while keeping the bike's proportions clean.

45mm Tyre Clearance

Luma is built for roads as they actually are. Clearance for up to 45mm tyres gives riders the option to run fast road slicks, larger-volume tyres for comfort, or a more capable setup for broken backroads, light gravel and mixed-surface routes.

FiftyOne First

Luma was not designed around the motor. It starts with fit, handling and ride quality, then adds electric support in a way that feels useful, natural and enjoyable. It still needs to feel sharp, composed and rewarding to ride.

MAHLE X20 Assist

Quiet, compact and responsive, the MAHLE X20 system delivers discreet assistance when the road, route or rider asks for it. With up to 275W of peak power and range of up to 200km with the optional range extender.

Clean Integration

No bulky silhouette. No visual compromise. Luma keeps the proportions and identity of a modern performance bike, with the electric system neatly built into the platform. It looks like a FiftyOne and rides like a FiftyOne.

Ride Quality

Ride Quality

Luma starts as a proper all-road performance bike. Fit, handling and comfort come first, with the electric system built around the ride rather than the other way around. The result is a bike that feels composed on rough roads, sharp on fast tarmac and comfortable enough for longer days when the route keeps opening up.

Clearance

Clearance

Clearance for up to 45mm tyres gives Luma the freedom to move beyond perfect roads. Run a fast road setup for smoother days, or add volume for comfort, grip and control on broken backroads, light gravel and mixed-surface routes. The extra clearance makes Luma more versatile without losing the clean, performance-led feel of the platform.

Assistance

Assistance

The MAHLE X20 system was chosen because it suits the way Luma is meant to ride. Quiet, compact and responsive, it delivers up to 275W of peak power when needed, with a range of up to 200km when used with the optional range extender. The support feels natural and measured, adding help on longer climbs, rolling roads and headwinds without taking over the ride.

Weight

Weight

The MAHLE X20 is the lightest premium eBike system on the market. At approximately 3kg for the complete system, it allows Luma to remain light, responsive and performance-led. With complete builds from approximately 10kg, Luma avoids the heavy, dulled feel often associated with e-bikes, preserving the sharpness and ride quality expected from a FiftyOne.
