About the Mark2 X-Cross 450S E-Bike
The X-Cross 450S Step-Through Electric Gravel Bike is the perfect fusion of comfort and all-terrain performance. Designed for adventure seekers, it features a Shimano 11-32T 10-speed cassette, a powerful Danish Promovec motor, and Schwalbe G-One 4Season gravel tyres, making light work of tougher trails and inclines.
Hand-built in Europe and expertly prepared in the Mark2 workshop in Hampshire, this premium e-bike is built for durability and long-term performance. Upgraded from the standard X-Cross 450, the 450S boasts a lower-geared Shimano cassette for improved hill climbing, high-traction gravel tyres, and a bottle cage for added convenience. With a 450Wh power pack delivering up to 100km of assistance, your next adventure starts here.

View on TrustpilotWas a little dubious at first due to a lack of reviews about the website, but they turned out to be incredibly helpful. They kept me updated throughout the process, the delivery was quick and they were able to adjust last minute to deliver to my neighbour, as a result of me not being home to receive the the delivery.
