Super fast, super stiff, and all-day pedalable. For local trails, trail-centres, hike-a-bike and enduro duty. Evol keeps coming back for more.
The Evol was designed and tested in the UK – in every season. We’ve chosen custom butted 6061 aluminium tubing for a perfect mix of weight, stiffness and durability. With long (but not ultra-long), low and slack geometry, Evol inspires confidence when descending at high speeds while the low bottom bracket means you can throw it hard into every corner. It pedals well too as the geometry gives a comfortable neutral riding position, keeping your weight central so you won’t waste energy on the uphill slogs (save it for the descent!).
To give that bottomless suspension feel, we’ve used the tried and tested 140mm Horst link suspension with custom tune Rockshox Deluxe RT shock. Combined with the 150mm Rockshox Yari, Evol grips brilliantly on climbs and tracks beautifully across difficult surfaces so you won’t get knocked off your line.
We’ve been obsessive when it comes to the little details that matter too. There’s internal cable and stealth dropper routing, clearance for 29 x 2.6 tyres and proper space for a bottle.
Simply put, the Evol is our dream built into a custom-butted alloy reality. An enthusiastic and capable Enduro-lite trail bike designed for enhanced fun-factor as you’re ragging it round the trail. You could take the Evol to an Enduro race, but it’s equally at home on a long day at the local trails.
Long, slack and low geometry for a confidence inspiring and forgiving ride. Pedals well too, with more neutral geometry keeping your weight central on the climbs.
Metric Shock Standard
Designed around metric shock sizing standard, with lengthened shocks and shorter strokes that increase bushing overlap for more smooth, supple, sensitive and reactive suspension action.
Horst Link Suspension Design
The tried and tested Horst link suspension design allows the suspension to stay active when braking.
Clearance for up to 29 x 2.6in tyres.
Internal Cable Routing
Internal routing in the front triangle for clean lines; threaded bottom bracket shell.

SizingIt is important to get the right size bike, if the bike fits it will be faster, more comfortable, and easier to handle. You can also take into consideration the standover height to ensure you pick a bike that will be a good fit. If you measure your inside leg and ensure there is a minimum of an inch from the toptube to your crotch this will give you enough seatpost adjustment to find your optimum saddle height. Generally we recommend:
- Riders between 5ft 2in and 5ft 7in
- Riders between 5ft 6in and 5ft 10in
- Riders between 5ft 9in and 6ft 2in
- Riders of 6ft 2in +

The fact that the Singletrack Awards are voted for by its readers - super keen riders, just like us - makes winning this award even more special.
Neil our Sonder Designer says: After getting runner up for the last 4 years It’s amazing to finally get a win at the Awards, and to do it with what is my favourite bike so far is even sweeter! The original Evol was a really fun 27.5” trail bike that I absolutely loved so reworking it into the 29er Enduro-Lite bike it is now was a bit of a gamble, good to know that people love the results as much as I do!!
