AM.170 is now available online!

April 19, 2023

The AM.170 is here!! Our hard-hitting big mountain enduro bike has a mixed wheel set up, straight through seat-tube and 170mm of rear travel and its totally awesome!! Our design and engineering team worked closely with Dan Atherton to create this stunning all-rounder that is “a big hitter in the bike park and a beast out on the trails.”


Dan said “I’m so stoked on this one. This bike is genuinely our best yet! It’s most at home charging downhill but its pedalling ability surprised me from the first ride, the AM.170 is equally happy doing all day big mountain days as it is taking on the Oakley line. If I had to choose just one bike from our range to ride every weekend, this would be the one!”

The AM.170 includes all the learnings from our  DH mullet bike that saw Andi Kolb on the podium four times last season; it’s awesome on the downhill but it also builds upon the award-winning AM.150 so it’s mega on the climbs…You can boost jumps, and really push hard in the park, but when you’re up for an adventure the new geometry and the DW6 platform work together to make those big mountain style missions altogether more rewarding.

Atherton Bikes CEO, Dan Brown said “This bike has been thoroughly tested on bike park jump lines, National stages of the British Enduro Series and the 20 minute+ Enduro descents that Athy has built here in the Dyfi Forest. When we head out there on a staff ride this bike is all time.”


The AM.170 is built around Dave Weagle’s DW6 suspension platform, a development from his DW4 four- bar linkage designed to work with Atherton’s titanium lugged construction and offer an awesome all round kinematic. The entire Atherton team ride every weekend and have put in a lot of work on “ride feel”. DW6 offers outstanding small bump sensitivity, good support in the mid-stroke and is progressive enough to accommodate the biggest of hits. Custom carbon tubing achieves the perfect balance of stiffness and compliance so whether you’re climbing or descending this bike achieves maximum traction and a totally mind-blowing feeling of connection with the trail.

Moving to a mullet set-up means that we’ve been able to use a straight through seat-tube so you can keep the seat low for the descent but still get maximum efficiency for the climbs.

We continue to place a huge emphasis on physical fit. Dan Atherton said “20 years of racing showed us just how much of an advantage that (perfect-fit) brings so when we started Athy Bikes we wanted to offer that to everyone.” The 170 is offered in 22 different sizes, from 410mm to 530mm reach which means every rider can order a perfect-fitting bike… there is even a custom-size option for mm perfect match; though with 10mm increments between sizes almost everybody will find a near perfect-fit from the standard size range. As with existing models in the current range, the seat tube angle varies with size to make sure that riders will always be in a great seated position on the bike.

Our commitment to rider choice is reflected in a range of three distinctive builds and a frame-only option, each with the choice of Air or Coil shock and either 170mm or 180mm upfront to give an even more personalised riding experience. As usual you’re free to switch components, or even exclude components from your order to create your own dream build.

 Prices for the AM.170 start from £4500 for a frameset which includes a Fox DHX2 Coil or Fox Float X2 shock.

All AM.170 builds are compatible with Sram’s new direct mount drivetrains, available as an upgrade – Call for more info!

All bikes in our Additive range are designed, hand-crafted and tested in Machynlleth, Mid-Wales and include a lifetime first-owner warranty, including Bike Park use. 

“I’m super impressed with the capabilities of the new A.170, not that I didn’t think it would be good but it did exceed my expectations. It’s so stable whilst descending, it makes you just wanna go faster. It feels like a mini downhill bike but the best part is you can climb back up and do run after run.” Charlie Hatton, Continental Atherton Racing
