Atherton Bikes introduced its first eMTB simply yesterday, with presales of the primary preproduction run restricted to only 50 bikes. In lower than 24 hours, all 50 of the primary presale batch have already bought out, and nobody has even seen “a full physique shot but.” In response, a second presale has already begun for an additional preproduction batch of fifty bikes, forward of the official launch in April 2026.
By taking its time, Atherton Bikes has clearly generated anticipation and curiosity for its first eMTB, often called the S.170E. “Somewhat than speeding to market, the S.170E has been formed by years of EMTB driving within the Dyfi Valley,” says Atherton. “The result’s a full-power enduro EMTB constructed round steadiness, sturdiness, and correct match, developed to the identical requirements as each analogue Atherton Bike.”
The model says the S.170E was designed and constructed across the objective of making “one of the best dealing with full-power eMTB Atherton can create.” With that handling-first design method, Atherton intends to ship the identical trip really feel as its analog bikes, however with the class-leading energy of the Avinox drive system.
Atherton S.170E Particulars
All this pleasure, and we don’t even have the entire particulars but. We’ve most of them, however as talked about above, we haven’t even seen any pictures of the entire bike, simply element photographs of assorted components. We’ve seen sufficient to comprehend it seems to be fairly typical of Atherton bikes, with the signature lug-and-tube aluminum chassis. On this case, that’s additionally going to incorporate a motor and a battery within the downtube of the body, in fact.
With a reputation like S.170E, it’s additionally evident that this bike is supposed to be fairly much like the non-electric S.170 enduro bike. As such, it makes use of the DW4 suspension design and will get 170mm of rear wheel journey, paired with a 180mm fork. The body is designed round a mixed-wheel configuration with a 27.5” rear wheel and a 29” up entrance.
Just like the model’s different bikes, the lug-and-tube building gives loads of sizing flexibility, and the S.170E is obtainable in a whopping 12 body sizes. Key geometry options are a 63.6-degree head tube angle and a ~76.6-degree seat tube angle, with chainstay lengths beginning at 435mm and rising to 445mm on bigger sizes. Attain begins at 405mm on dimension 1 and grows in 10mm increments to 515mm on dimension 12. Take a look at the chart under for full particulars.
Avinox-Powered
Atherton selected the highly-regarded and really highly effective Avinox drive system for the S.170E. In 2024, Avinox took the eMTB world by storm and kicked off a motor energy race, one which it’s nonetheless successful with as much as 105Nm of torque and 1000W of peak energy. Atherton says it was “chosen not only for its industry-leading output, however for its compact dimension and refined energy supply.”
Past massive energy and a refined supply, Atherton states that the scale of the Avinox motor allowed them “to maintain geometry, kinematics, and chassis proportions precisely the place they needed them, with out compromise.”
Battery Dimension and Vary?
The most important query mark with the S.170E is battery dimension. The model states that it “will run a full-sized battery which gives the vary wanted for a stable trip, with out tying the bike down in the case of dealing with and maneuverability.” However, they don’t state how giant that battery will truly be. As a substitute, they are saying “precise Wh figures might be revealed at launch, however thorough testing within the Dyfi Valley it’s confirmed to be good for 1600-2000 meters of vertical.”
Based mostly on what we learn about Avinox drive techniques and batteries, we assume meaning it would include both 600Wh or 800Wh, that are the present choices. Maybe they’ll let consumers select, or perhaps they’re arising with their very own proprietary dimension? Feels like we’ll discover out in April.
Atherton S.170E Construct Choices
The S.170E is at present accessible in three construct choices, with the first differentiators being the suspension and drivetrain. All builds come geared up with the identical Hayes Dominion A4 brakes, Mavic E-Deemax wheels, and Continental Kryptotal tyres.

Atherton S.170E: Availability
Atherton’s new eMTB doesn’t formally launch till April, however the second spherical of presales is open now. Apparently, in 2026, solely prospects within the UK and EU will be capable of order eMTBs from Atherton, with international distribution deliberate at a later date. If you happen to’re , right here’s how the presale works:
£1,000 deposit secures a motorbike
Steadiness twenty eighth February 2026, forward of manufacturing begin
Presale bikes are scheduled to start delivery April / Could 2026
Orders may be cancelled previous to manufacturing with a full deposit refund

Creating the Atherton S.170E
If you happen to’re interested by studying concerning the improvement of Atherton’s first eMTB, the model has put collectively a video collection. The primary two episodes are out now, and there may be apparently one other one within the works. Test them out under.
