Sonder Transmitter

Ultra-capable 27.5" hardtail hooligan - fast, lively and fun.

Sonder Transmitter

Progressive sweetspot geometry cuts trails like a scalpel. Transmitter flows across cambers, roots, rocks and ruts. Get speed, agility and masses of fun with a long wheelbase, long trail and long reach.

A long, low and slack hardtail - with geometry dialled for 2024. A hooligan of a bike with a ferocious appetite for trail centres, singletrack and big mountains.

With hardcore northern design roots the Transmitter is the bike for the toughest lines. Smash it down Jacob’s Ladder, slog up Garburn … and be quicker than you’ve ever been on everything in-between.

Transmitter is one of the most capable 27.5 hardtails on the market and is ready to take on proper mountain trails: Snowdon on a crisp winter day, Colorado singletrack with killer views and grinders where you’ll be glad of the 50 tooth… Yet, pad up and grab the full-facer and you can still take a day trip to Bike Park Wales or alternatively whip around Cannock Chase on a Sunday afternoon chasing your lycra-clad mates.

The signature flattened top tube gives vertical compliance but lateral stiffness - it is an all-mountain bike. That long wheelbase combined with the slack front end, size-specific chainstays and a lowered bottom bracket give stability and control through the rowdiest of terrain.

Transmitter is designed around boost 148/110 standards and 27.5" 2.6/2.8" tyres, and optimised for 1x groupsets. The geometry and extra grip from those big tyres means even the most sheepish rider will tackle steep sections, up and down, like a pro.

Transmitter frames feature internal cable routing through the downtube, integrated headsets, through-axle hubs, refined dropouts, butted tubes and smooth welds.

Transmitter is a fun trail bike that just fits in with hard riding. You’ll be able to push yourself harder than ever before!
