The Sonder Concierge Service: Your Bike, Your Way

For many, owning a custom frame is the ultimate dream; geometry, feel and function combined with only you in mind and details matching exactly the journeys you have planned. A bike that makes you proudly say ‘that’s my bike’.

With years of experience designing award-winning bikes, Neil and the team at Sonder can turn the dream of owning a custom bike into a reality. The right head angle, the perfect top tube length. Shorter stays or an eccentric bottom bracket? As radical as you like.

Whether your dream is a long-distance tourer that soothes your aches and pains or the perfect off-road explorer, we’ll take it from that initial spark in your head all the way through to the finished article.

We'll chat through your specifications and keep you updated at every step of the way; Meticulously sketched here in the UK, hand-built by specialist titanium-workers and finally assembled at Alpkit Campus in Nottingham.

Share the joys of riding together no matter the road you travel.

Cycling is not a solo sport and the rhythm of tandem riding brings out a broad grin wherever you go. Tackle steep singletrack, flow down downhills and ride fully loaded on tarmac. Two minds, one thought, the togetherness of riding together with all you need for days and nights in the wild.

A capable bespoke hand made tandem mountain bike designed for your size, geometry and specification. Made from aeronautical grade titanium and with a 10 year guarantee.

Custom built bespoke Cahoot frames from £2,999; complete bikes from £3,999.

Cahoot, to share equally; become partners

A tandem lets two riders of different strengths and ability ride together and share in the joy of riding.

Tandem mountain bikes are fast and capable on road, off-road. Designed with the Tour Divide in mind, long trips or a LEJOG is well within its capability. You can ride fast on tarmac with the knowledge of being able to attack steep singletrack that’s daunting on a regular hard tail. Made with twangy titanium with slacker head angle it has a modern geometry to last a lifetime.
