Aerospace meets Workshop. 

Building simple bikes is a complex business.

Starling Cycles hand build steel, custom, full suspension mountain bike frames in Bristol, UK.

Every Starling Cycles mountain bike frame is built to be beautifully simple, drawing on Joe’s 20 years of aerospace engineering experience.

So much of modern bicycle design is overly complicated - sacrificing performance for the arms race to be the “next big thing”.

In creating Starling Cycles, Joe has put simplicity at the forefront of design and created frames that are tough, fast, easy to maintain, very fun to ride and beautifully uncomplicated. They are the antithesis of marketing-led design - built for performance on the trail. 




Every Starling Cycles mountain bike, be it a Murmur or a Swoop, is a one-off. A unique, dream build for its owner.

Specify head tube angle, down tube length/reach and seat tube length. Then choose your colours and decide if you want a frame or a frame plus shock. We'll will help you to create a bike that exactly meets your vision of the perfect mountain bike. 

Not an expert? No problem. We can help guide you through to make sure that your bike is exactly right.


Swoop 27.5"

The Swoop is our original, flagship frame.

It's the perfect tool to slay your local Enduro or mini-downhill race or just to smash, grinning ear-to-ear, down the steep stuff in the woods. It is simple to ride, to setup and to maintain with a tough single pivot design and uncomplicated linear suspension ratio.

“Wonderful attention to detail, neat gussets, super clean joints and finishing.”

Murmur 29"

The Murmur is brand new from Starling Cycles.

We took the Swoop’s proven suspension design and tubeset, adapting it to create a fast, aggressive 29’er that is beautifully simple to ride and a breeze to setup and maintain.

Rave reviews.

Dirt, SingletrackEnduroMTB, MBUK, WideOpenMag and RiderFlow have all swung their legs over and been suitably impressed.

“I simply wanted to keep riding it and had every intention of holding onto this beautiful piece of work for as long as I possibly could.”
Today this Starling Cycles steel, garden-shed-built bike went consistently quicker than all carbon 6K 150-165mm enduro bikes. Perfect riding conditions over a rough 2min 30sec track. And not just one rider but two.

Yes we’ll be taking this test to more tracks, but for now we are FULLY blown away #curveball
