Great fun and won't let you down for performance, but it might be too firm for some
Well balanced handling
A firm ride for UK road surfaces
Low spec wheels for the money

We test BMC's Roadmachine X One Disc, a bike that blurs the line between road and gravel.
Stiff frame in the right places
SRAM shifting is excellent
Tan wall tyres make everything look better
Large jumps between gears
Not fully internal cabling
Large volume tyres didn’t handle as well as we’d like

SRAM XLPR-Schaltung und voluminöse, profilierte Reifen – wird das BMC Roadmachine X damit zum schnellsten Gravel-Bike aller Zeiten oder zum Offroad-tauglichsten Rennrad? Die Schweizer versprechen jedenfalls das ultimative Allroad-Bike, das auch vor ausgedehnten Schotter-Ausritten nicht haltmachen muss. Ob das Konzept funktioniert, zeigt der direkte Vergleich mit den sechs besten Allroad-Bikes des Jahres.
Long-distance comfort/mounting points
The frame would make an excellent basis for a custom build
Generous tire clearance
Components limit the bike’s versatility
Lack of precision and traction on asphalt
Not completely integrated brake lines

Superb handling and smoothly integrated assistance make the new AMP a worthy addition to the Roadmachine range
Brilliant, natural ride
Quality contact points
Tyres could be better

Innovation has never been a design element lacking in the BMC catalog, as the Swiss brand has led the march in road bike innovation for years.

Gorgeous and distinctive integrated design, a lovely ride, and a top-shelf build kit. Just try not to choke when you see the price tag.
Comfortable ride, ultra-sleek profile, premium build kit, “locked-in” handling feel.
Premium cost, sizing limitations from the integrated front end.

With its new carbon frame, BMC’s Roadmachine X is an all-road endurance bike looking to go further and faster into the gravel world, but has it strayed too far from the road?
Road plus tyre sizes offer comfort and confidence
1x SRAM XPLR groupset adds drivetrain simplicity and an effective spread of gears
Sorted geometry finds balance on- and off-road without dulling the ride experience
External brake hoses simplify home mechanics
Limited aero considerations
No mudguard mounts limit wet weather usability
Limited tyre volume will come unstuck on real gravel
42cm bars on smaller sizes
