150 THE ULTIMATE ALL-ROUNDERS

Our 150 mm enduro bikes are built, tested, and ridden to the limit in the Dyfi Valley. These all-rounders are responsive and playful, letting you find and hold speed on almost any trail, yet stay composed when the terrain gets rough.

The lug-and-tube chassis delivers a perfect fit across the range, with the strength to back it up: every model is EFBE Category 5 rated and built to be ridden hard. And when it’s time to spin back to the top, the supportive DW-link suspension and poised pedalling position deliver eager, efficient climbing performance.

Go A.150 29er if you want all-day speed and stability, or choose the mixed-wheel A.150M or S.150 for extra agility and more rear-wheel clearance when things get steep.

Unrivalled Fit

By offering 22 sizes (at 10mm increments) within our A Range, as well as a mm perfect custom-fit option, and 12 sizes on our S Range, riders don't have to settle for an 'almost right' setup. These bikes are built to feel good from the first run.

Carefully Crafted Chassis

Precision-printed or CNC-machined lugs are bonded to size-specific tubes in Wales, giving us full control of ride feel without the limitations of carbon moulds or the heat distortion and fatigue ceilings of welds. A and S series frames are bonded with double lap-shear joints which creating a package that's engineered to lat a lifetime.

All-Mountain Angles

Geometry that hits the sweet spot. A 64.5–65° head angle for confident descending, paired with a 77.5–79.5° seat tube that keeps you centred and climbing efficiently. Size-specific chainstays maintain balance across the range, so every rider gets the same mix of stability, agility and precision.

THE FINE DETAILS

Dave Weagle’s DW Kinematic

The A-Range uses the 6 bar DW6 platform for maximum refinement, while the S-Range runs the simplified DW4 layout. Both deliver high initial sensitivity and a controlled, progressive leverage curve. Engineered to work with neutral shock tunes for predictable, simple setup.

Hardworking Hardware

Our bikes exclusively utilize threaded bottom brackets (BB). Beyond that, we've standardised barrel nuts and fasteners throughout, making it simpler and faster to source spares.

Dyfi-Proof Downtube Protector

All our bikes come equipped with a rugged downtube protector designed and manufactured in the UK using multi-jet fusion technologies, impacts are dampened and dispersed across a larger area.

UK Patent Application Number GB2400886.4

ENDURO 150 REVIEWS

With the Atherton S.150, aluminium enthusiasts can now get their money’s worth without sacrificing the unique manufacturing technique, the resulting distinctive look, and the extensive size range. Atherton’s alloy trail bike clearly focuses on performance, as evidenced by its robust components and lack of unnecessary frills. On the trail, the S.150 plays in its own league, combining remarkable composure and playful agility like almost no other trail bike.

Enduro Mag, S.150

The Atherton A150 can deliver top-level performance as an enduro race machine, even on really demanding tracks, especially if stability, comfort and composure under braking are key considerations

MBR Magazine, A.150

⭐⭐⭐⭐⭐ Lug and tube construction, on paper it seems simple, but it’s the alpha and omega of current engineering. When you start to look closer, you realize that the AM.150 is a real work of goldsmithery: no trace of glue, resistant paint with a matte finish, no play at the junctions between titanium and carbon, no parasitic noises…

Guillaume Allard, A.150

⭐⭐⭐⭐⭐ My old bike just felt unbalanced for the majority of riding I was doing. The A.150 Atherton made me feel right at home. Precise steering, controlled and so much more grip.
