Mark2 X-Cross 450S Electric Bike Step Through With 460Wh 12.8Ah Removable Battery

Unleash Your Adventure with the Mark2 X-Cross 450S Step-Through Electric Gravel Bike

Take your ride to the next level with the X-Cross 450S, a powerful and versatile electric flat bar gravel bike built for both everyday comfort and rugged terrain.

Designed for riders who crave adventure without sacrificing ease of use, the 450S combines a low-step frame, Shimano 10-speed gearing (11-32T cassette), and a reliable Danish Promovec rear hub motor to deliver smooth, controlled power, especially when tackling hills or off-road trails.

Fitted with premium Schwalbe G-One 4Season gravel tyres, this e-bike offers exceptional grip and durability in all conditions, whether you're commuting through the city or exploring gravel paths and country roads.

With a 450Wh removable battery, the X-Cross 450S offers up to 100km of assisted range, giving you the freedom to ride further and longer.

Each X-Cross 450S is hand-built in Europe and carefully prepared in the Mark2 UK workshop in Hampshire, ensuring lasting quality and reliability.

Compared to the standard X-Cross 450, the 450S features key performance upgrades such as:

    Lower geared Shimano drivetrain for improved hill-climbing

    High-traction gravel tyres

    Integrated bottle cage for added convenience

Whether you're riding for fitness, commuting, or heading off-road for the weekend, the X-Cross 450S offers the perfect balance of comfort, control, and performance.
