We’ve been following the Sonder story quite closely for almost two years now. Sprouting out of the Alpkit tree as a new UK-focussed bike brand, Sonder Bikes launched its original alloy Transmitter hardtail back at the 2016 London Bike Show. With a tough alloy frame, kicked back trail geometry and very sharp pricing thanks to its consumer-direct sales model, the Sonder Transmitter captured the attention of many, and even earned itself a nomination in last year’s Singletrack Reader Awards for Best Bike Under £1000.
Since then, things have been cranking along for Sonder. And so Neil Sutton, Sonder’s head honcho/bike designer/tester/bike builder/customer service man, has been very busy. He’s designed a new generation alloy Transmitter, and earlier this year, rolled out a carbon fibre Transmitter – a bike we currently have on test (check out the detailed First Look article here). There’s even been some news on the drop-bar side of things, with Neil having designed a new carbon fibre disc brake road bike called the Colibri (check it out on Grit.cx here if you’re into that sort of thing…).
While all of that’s been going on however, Neil has had something else up his sleeve. Something with a little more squish. While Sonder’s off-road range has largely been of the rigid-framed variety up until now, it would appear that that’s about to change with the all-new Evol full suspension trail bike.

The new Sonder Evol arrives on the scene after 18 months worth of prototyping and testing. The model you’re looking at here is the third iteration of the design process, though not a whole lot has changed since the first prototype, aside from the back end being shortened a touch and the bottom bracket being lowered too. Otherwise Neil has been pretty happy with the frame design, suspension and geometry he originally settled on.
The production versions are due to arrive before the end of November, and it’ll be available as both a frameset and as a complete bike. Pricing is still to be confirmed, though Neil tells us the Evol frameset will sell for £899 with a RockShox Deluxe RT rear shock, while complete bikes will start at £1599 – which is insanely good value for money!
Prior to the Evol becoming available to the public, Neil wanted to visit us at Singletrack Towers to show us his new bike. This is the first time the Evol has been shown to the public, and so we took the opportunity to film a video with Neil, which you can watch in the video above. We were also able to swing a leg over a pre-production version of the Evol, and you’ll be able to read the first ride report very soon. In the meantime, lets take a closer look at some of the details found on Sonder’s brand new full suspension trail bike.
With a focus on durability and value for money, the Sonder Evol chooses alloy tubes to piece together its tough-looking frame. There’s a four-bar suspension design with 140mm of travel out back, and a top tube-mounted rear shock that’s driven by a black alloy rocker link. Pivot points feature alloy hardware and sealed bearings, and other practicalities include the ability to fit a water bottle inside the mainframe, and a threaded bottom bracket shell.
The Evol is designed for use with a 150mm travel fork, and geometry has been optimised around a compact 35mm long stem and 780mm wide handlebars. There’s room for up to 2.6in wide 27.5in tyres, and overall the Evol has been designed as a capable and fun do-it-all trail bike. Neil says you could race it at an enduro event if you wanted to (it’s plenty strong to do so), but it’s mostly been built as a fun bike for weekend warriors.
The rear derailleur hanger is similar to a Syntace X-12 system. The hanger is a chunky piece of alloy that provides a stiff platform for shifting, and attaches to the frame via a hollow alloy bolt, and a single locating pin that helps to stop it from twisting in the dropout. If you do snag a stick through the spokes or hit the rear derailleur on a rock, the hollow alloy mounting bolt is designed to break-away, ideally leaving the hanger, derailleur and frame intact in such a scenario.
After finishing off our ride at Lee Quarry, Neil casually pulled a box out of his car with a couple more frames inside. The Sonder Evol will of course be available as a frame-only for those who wish to build their own complete bike up, and pricing is going to be quite sharp. There will be four frame sizes starting with a Small and ending at an X-Large. Three colours are available, with the Orange, Slate and Lime Green colours all electing for a high quality matte finish that Neil says is very durable. This colour here is the understated Slate finish, complete with blue highlights.
We’d love to hear what you guys think of the new Sonder Evol! And if you have any questions about the bike, submit them in the comments section below and either we’ll endeavour to answer them for you, or we’ll get Neil to chime in with his input. Otherwise stay tuned for the first ride report of the all-new Evol from Sonder Bikes!
