Developed from Dan Atherton’s years on the Enduro World Series circuit, the A.150 is our flagship enduro platform: a bonded titanium-lug and carbon-tube chassis, additive-manufactured in Wales to give us full control over stiffness, compliance and fit.
Dave Weagle’s DW6 suspension platform was engineered specifically for our A-Series bikes, perfectly balancing traction and support through the full 150 mm of travel.
Available in two configurations: the full-29er A.150 for all-out speed and stability, or the mixed-wheel A.150M for more agility and extra rear-wheel clearance on the steeps.
Precision-built. Rated category 5. Proven in Dyfi.
WHICH ONE'S FOR YOU?
MULLET
The mixed-wheel option tightens the chainstay length and shortens the wheelbase for quicker direction changes and a more dynamic ride feel. The 27.5” rear wheel also increases tyre-to-rider clearance on steep sections, while the 29” front keeps rollover and stability. Same chassis, same travel, more agile.
29ER
The full-29er setup is the choice for riders looking for efficiency, confidence at speed, and a more stable platform through the rough. If your riding leans toward big mileage, open mountains, or race-pace stages, this is the one.
3D-printed titanium lugs and carbon tubes are bonded using double lap-shear joints delivering incredible strength without a fatigue ceiling. This method gives us full control of stiffness, compliance and sizing, beyond the limits of moulded carbon frames.
PERFECT FIT SIZING
The A.150 platform comes in 22 sizes with 10 mm reach steps and size-specific geo, so every rider gets the same handling balance and weight distribution. Choose your model, and our fit calculator will get you on the ideal setup.
TRAIL-TUNED GEOMETRY
Balanced head angles between 64.5°–65°, steep 77.5°–79° seat tube angles, and size-specific chainstays. Every rider gets the same dialled cornering feel, efficient climbing position and chassis stability.
Our most refined kinematic, engineered exclusively for our A-Series chassis. The 6-bar linkage serves up 150 mm of rear travel paired with a 160 mm fork, tuned for grip, mid-stroke support and predictable end-stroke control.
LIFETIME WARRANTY
Rated and approved by EFBe to their toughest Category 5 rating means we're happy to offer first owners warranty cover for life, including bike-park use. These frames are designed to be ridden, not babied
PORT-TO-PORT CABLE ROUTING
Fully guided internal routing from entry to exit. No rattle, no fishing with cables, no frame noise. Service in minutes, not hours.
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
Overall, the “first ride” was incredibly promising on the Atherton Bikes A.150, proving that they’ve put together a real ripper of a bike. I felt sad to give back so soon.
Loam Wolf, A.150
