Genesis Croix de Fer 60 E-Gravel Bike 2026 with Mahle X30 Electric Assist System

The Genesis Croix de Fer 60 2026 is the most capable bike in the Croix de Fer range — a premium e-gravel bike that combines the heritage and ride quality of a Reynolds 725 steel frame with the transformative power of the Mahle X30 electric assist system. The result is a bike that opens up longer routes, bigger climbs, and more ambitious bikepacking adventures to a wider range of riders, without sacrificing the feel and character that makes steel gravel bikes so compelling. Available in sizes from X-Small to X-Large, it's a unisex platform built to fit a wide range of riders.

The Mahle X30 system delivers smooth, natural-feeling pedal assistance that integrates seamlessly into the ride — it amplifies your effort rather than replacing it, making climbs more manageable and longer days more achievable. A carbon fibre fork keeps the front end responsive and reduces weight where it counts. The Shimano GRX 2x10-speed drivetrain provides precise, gravel-optimised gear changes across a wide range, while Shimano hydraulic disc brakes deliver consistent, powerful stopping in all conditions. Amplitude G-100 tubeless-ready wheels paired with Maxxis Rambler 45mm tyres offer excellent traction and puncture resistance on loose and mixed surfaces, and the Amplitude finishing kit rounds out a cohesive, well-considered build.

The Croix de Fer 60 sits at the top of the Genesis Croix de Fer family. If you're looking for a non-assisted alternative at a similar specification level, the Croix de Fer 50 2026 offers a Shimano GRX 2x12-speed build on the same steel platform. For those interested in the broader e-gravel category, we stock a range of options to suit different budgets and riding styles.

What It's Good For

• Long-distance e-gravel riding with smooth, natural-feeling electric assist
• Tackling bigger climbs and longer routes with loaded bikepacking setups
• Riders who want the ride quality of a steel frame with the range-extending benefit of electric assist
• Gravel-optimised performance with Shimano GRX 2x10-speed drivetrain
• Confident all-weather braking with Shimano hydraulic disc brakes
• Reduced puncture risk with Amplitude G-100 tubeless-ready wheels and Maxxis Rambler 45mm tyres
• Responsive front end with a carbon fibre fork
• Unisex fit across a full size range (X-Small to X-Large)

What It's NOT Good For

• Riders who want a non-assisted gravel bike — see the Croix de Fer 50 2026 for a comparable non-electric build
• High-speed road racing or competitive events where an aero carbon frame is required
• Aggressive full-suspension mountain biking on technical singletrack
• Riders prioritising the absolute lightest build — steel frames with an e-assist system carry more weight than carbon alternatives

Frequently Asked Questions

What sizes are available?
The Croix de Fer 60 2026 is available in X-Small, Small, Medium, Large, and X-Large. We recommend checking the Genesis geometry chart or contacting us for a personalised sizing recommendation based on your riding position and inseam.

How does the Mahle X30 electric assist system work?
The Mahle X30 is a compact, rear hub-integrated motor system that provides smooth, progressive pedal assistance. It's designed to feel natural and unobtrusive — amplifying your pedalling effort rather than taking over. The system is controlled via a handlebar-mounted unit and is compatible with Mahle's app for ride data and settings adjustment.

Are the wheels tubeless ready?
Yes — the Amplitude G-100 wheels are tubeless ready and come paired with Maxxis Rambler 45mm tyres. You will need to add tubeless valves and sealant to complete the setup, which we can assist with at point of purchase.

How does the Croix de Fer 60 compare to the Croix de Fer 50?
Both bikes share the same Reynolds 725 steel frame and gravel-focused geometry. The key difference is the Mahle X30 electric assist system on the 60, which extends range and makes climbing easier. The Croix de Fer 50 uses a Shimano GRX 2x12-speed drivetrain without electric assist, making it lighter and more suited to riders who prefer an unassisted ride.

Is this bike suitable for all genders?
Yes — the Croix de Fer 60 uses a unisex geometry designed to work well for all riders across the available size range.
