Sonder Evol Active and plush: climb like an ibex, descends flat out

Enthusiastic, playful, tough, responsive 650b 140mm mountain bike. In its element on extreme ground and unburdened elsewhere.

Active and plush suspension for a bottomless feel and poppy ride, climbs well and descends flat out. Super fast, super stiff, all the time. For local trails, bikeparks, trail centre black runs, hike-a-bike and enduro duty. Evol keeps coming back for more

"It’s a bike built for hard knocks, ragging around and acting like a hooligan on. Take it on a bigger, more pedally day in the hills and you’ll be rewarded with good times all the way as it climbs to the top before soaking up most of what you can throw at it on the way down." Singletrack Magazine

"Impressively stiff, up-to-date and upgradeable agro trail frame ... a shrewd long-term investment" MBUK magazine

WHERE

Local trails, playing in the woods, bikeparks, trail centre black runs and skills parks, hike-a-bike in the UK mountains and onduro duty. Evol keeps coming back for more.

BUILD

Designed and tested in the UK. Custom butted 6061 aluminium tubing. Tried and tested 140mm Horst link suspension with custom tune Rockshox Deluxe RT shock. Internal cable and stealth dropper routing. 1x specific and clearance for 650b x 2.6 tyres. Adjusted for 150mm forks.

Simply put, the Evol is our dream built into a custom-butted alloy reality. An enthusiastic and aggressive 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. 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!

The top tube mounted RockShox Deluxe RT 140 mm travel shock in the rear boosts traction on the steep and technical terrain for a comfier and more playful ride. Built around new metric shock standards for increased bushing overlap, the suspension is smooth, supple, and reactive, increasing sensitivity for a playful and enthusiastic feel.

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.​

Tyre Clearance

​Clearance for up to 27.5 x 2.6in tyres.

Internal Cable Routing

​Internal routing in the front triangle for clean lines; threaded bottom bracket shell.

Sizing

It 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.
