Sonder Mountain Bikes
Sonder mountain bikes are built on the belief that the best ideas shine. They don’t need to shout. We don’t do gimmicks or follow hype — we build the bikes we want to ride. And because we ride year-round in the UK, we know what matters: geometry that just works, durable materials, and a ride feel that brings confidence and fun to every trail.
Sonder Mountain Bikes
Modern mountain bikes designed for real trails and real riders.
We were early adopters of long, low, slack geometry. We championed 650b+ hardtails before they became mainstream. Our approach isn’t to push boundaries for the sake of it — it’s to make sure every Sonder is dialled for the way people actually ride. We focus on substance, clarity and craft — so the ride can do the talking.
Transmitter
Long. Low. Slack. A hooligan of a hardtail with one default setting: rowdy. Planted and agile with 650b+ tyres for shredding singletrack and big mountain trails.
Signal Ti
Agressive 29” titanium hardtail designed to climb as well as it sends. Feed it fast-flowing singletrack and tasty big mountain trails and strap yourself in.
Cortex
The Cortex doesn’t believe in the ‘n+1 rule.' Whatever the trail, it fancies it. Big time. A lively 140/135mm travel 29er, it'll climb for days and chomp through descents.
Frontier
Multi-activity 29er for fast, flowy trails, hurtling over cross-country and loading up with bags for days of deep backcountry riding. No nonsense. No frills. No fuss.
Broken Road
Fully custom-built titanium hardtail for riding to the ends of the earth, off the map and back. Or, you know, just Scotland. Built for absolute multi-day comfort.
