Genesis Revolutionizes Gravel Cycling with New Croix de Fer E-Bike

Genesis has introduced an electric-assisted version of its highly regarded Croix de Fer gravel and adventure bike. This marks the first time the classic steel-framed model, celebrated for its versatility and robust performance, has been equipped with an e-assist system. The new e-bike integrates the Mahle XS motor system, aiming to provide a seamless power boost while maintaining the bike's distinctive ride quality.

Priced at £4,499, the Croix de Fer 60 features a lightweight Mahle X20 hub motor paired with an external 171Wh battery, with the entire system adding just 2.6kg. This design philosophy focuses on augmenting the riding experience rather than transforming it into a fully electric one, allowing riders to enjoy the familiar feel of the Croix de Fer with added support for challenging terrains or longer distances.

The Evolution of a Classic: Integrating Electric Assist

Genesis has brought electric assistance to its celebrated Croix de Fer range, a move that aims to enhance the bike's already impressive versatility. This evolution sees the integration of the Mahle XS motor system, a lightweight solution designed to complement rather than overpower the inherent characteristics of the steel-framed gravel bike. The development, spanning eight years, focused on preserving the Croix de Fer's unmistakable ride quality, ensuring that the electric assistance serves as an extension of the rider's capabilities, particularly on inclines or against headwinds. This strategic addition allows the bike to maintain its appeal to a broad spectrum of cyclists, from daily commuters to long-distance adventurers, while providing a subtle yet effective power boost when needed. The emphasis is on a natural riding feel, where the motor seamlessly integrates into the cycling experience, making it an even more adaptable companion for diverse cycling demands.

The newly introduced Croix de Fer 60 is equipped with the Mahle X20 motor, known for its compact size and efficient performance. This system delivers up to 65Nm of torque and a peak power output of 275W, offering substantial assistance without adding excessive bulk. Riders can control the motor via Mahle's e-Shifters, with options for smartphone integration or an additional PulsarONE display for metrics. The bike's 171Wh EX1 battery, weighing just over a kilogram, fits into a bottle cage mount and offers a claimed range of up to 60km, though this can vary based on usage. A key design principle is the ability to remove the battery and ride without assistance, as the motor incurs minimal drag, making it essentially a non-assisted bike with a mere 1.5kg weight penalty. The frame itself remains the familiar Reynolds 725 steel, paired with an Amplitude G200 carbon fork, and is specced with a Shimano GRX RX820 2x12-speed transmission and tubeless-ready wheels, supporting tyres up to 47mm. The £1,700 premium for the motor upgrade positions the Croix de Fer 60 as a competitive option in the electric gravel bike market.

Design Philosophy and Performance Enhancements

The core design philosophy behind the electric Croix de Fer centers on augmenting the existing ride experience rather than fundamentally altering it. Product manager Sam Lawson emphasized that the goal was to create a Croix de Fer with electric assistance, ensuring it retained its distinct feel. The Mahle XS system, with its lightweight X20 hub motor and a modest 171Wh external battery, reflects this approach. The system is engineered to provide support only when necessary, acting as an extra gear for tackling steep climbs, strong headwinds, or fatigue on longer rides. This intentional design choice allows the bike to feel like a traditional Croix de Fer for most of the ride, with the electric assist seamlessly engaging to provide a helpful push. This balance ensures that the bike remains true to its versatile, all-rounder heritage while catering to riders seeking a little extra power.

Despite the addition of electric power, the fundamental characteristics of the Croix de Fer's frameset remain consistent. It continues to feature a durable Reynolds 725 steel frame and a lightweight Amplitude G200 carbon fiber fork, renowned for their comfort and resilience. The electric model is fitted with a Shimano GRX RX820 2x12-speed drivetrain, featuring 46/30T chainrings and an 11-36T cassette, providing a wide range of gears for various terrains. Tubeless-ready Amplitude G100 wheels, integrated with the X20 motor, and Maxxis Rambler 700x45mm tubeless-ready tires further enhance its gravel capabilities, with ample clearance for tires up to 47mm. The £4,499 price tag for the Croix de Fer 60 represents a £1,700 premium over the non-assisted Croix de Fer 50, a cost that reflects the advanced Mahle motor system and its seamless integration. This pricing is in line with other premium electric assist conversions, offering a sophisticated upgrade for those who value the classic Croix de Fer ride with an intelligent power boost.
