The Solaris isn’t just a bike; it’s your passport to unforgettable adventures and endless smiles on the trail.
The Solaris embodies over two decades of Cotic’s unwavering passion for crafting exceptional hardtail mountain bikes. This isn’t just another bike; it’s the culmination of our heritage, innovation, and the meticulous craftsmanship of our skilled frame builders in Czechia. We’ve poured our heart and soul into every detail to create a hardtail that not only inspires confidence but elevates the fun factor on every ride. The Solaris seamlessly blends agility on tight singletrack with composure on challenging descents, becoming an intuitive extension of your own riding style.
Constructed from premium Reynolds 853 steel and designed around fast-rolling 29-inch wheels, the Solaris delivers a trail feel that is simply unmatched. Prepare to be grinning from ear to ear, mile after exhilarating mile. It’s more than just a trail bike; it’s your precision singletrack tool, your trusted companion for technical trails, your reliable bikepacking partner for multi-day adventures, and your map-crossing machine for exploring the unknown. Thoughtful design touches, like ample space for bags and bottles, ensure it’s perfectly equipped for adventures of any duration.
Every ride on the Solaris is a testament to our commitment to building the best hardtail you’ll ever experience. It’s not just about the bike; it’s about the partnership it forges with you, empowering you to explore new trails, push your personal limits, and create lasting memories. Quite simply, the Solaris represents the pinnacle of Cotic hardtail design – the finest we’ve ever created.
To further personalize your ride, our full range of A La Carte custom paint options are now available for your Solaris frame.
Choose your perfect frame size, your ideal colour, and your preferred component build kit.
As unique as you are, the Solaris is tailored to meet your exact riding needs.
Now more than ever, it’s Your Bike, Built For You.
Is the Solaris the right bike for your riding style?
If you’re drawn to the speed and efficiency of 29″ wheels but crave a frame that can handle even tougher terrain and is optimized for 140mm forks and above, then the BFe is your answer.

Expert Reviews of the Cotic Solaris
GuyKesTV Live Ride Review: [Link to GuyKesTV Review]
GuyKesTV Chat’s with Cy about the New Solaris: [Link to GuyKesTV Interview]
Mountain Biking UK Head-to-Head Test January 2025:
“The Solaris is the kind of machine that lulls you into that happy place without you really noticing, because it’s so easy to work with.”
“At its core, the Cotic comes over as a bike that’s been refined to handle as sweetly as possible, and displays a real sense of passion and nit-picking for the ultimate ride quality.”
“Despite the extra cost (even compared to other steel hardtails)….if we were to grab a bike from this pair to go for a ride on, it would be the Cotic Solaris, all day long. There’s no caveat either, and the statement stands whether that was an XC mission, a trail outing or even hitting up some rougher enduro style tracks.”

Cotic Solaris Size Guide
| Frame size | Rider Height in centimetres | Rider Height in feet and inches |
|---|---|---|
| C5 | 184cm – 195cm | 6ft 0in – 6ft 5in |
| C4 | 182cm – 190cm | 5ft 11in – 6ft 3in |
| C3 | 176cm – 184cm | 5ft 9in – 6ft 0in |

| C1 | 162cm – 172cm | 5ft 4in – 5ft 8in |
This chart serves as a general guide. Longshot Geometry ensures ample standover clearance and a low center of gravity. We recommend choosing the size corresponding to your height and experiencing the benefits of a short, responsive 35-45mm stem. It’s a true game-changer in handling and control.
Our refined Cotic “C” Sizing provides more nuanced size increments, giving you greater flexibility to size up or down based on your personal preferences and riding style.
Consider your leg length, especially if you’re upsizing, to ensure compatibility with longer dropper posts. Excessive upsizing may limit dropper post insertion due to collar-seat tube contact. Maximum seatpost insertion figures are available in the geometry charts below.

We don’t design around a specific fork offset, as rider preference plays a significant role. To understand more about fork offset and its nuances, Click Here.

Features and Benefits of the Cotic Solaris
Our radical Longshot geometry is the core of the Solaris’s exceptional performance. It provides unmatched stability on challenging terrain, confident cornering grip, and laser-like precision on steep, technical trails. Paired with a super-short 35mm stem and optimized head angle, the Solaris encourages you to push your limits, seeking out every trail feature to jump, gap, and rail, while maintaining incredible connection and composure.
Hardtail Heritage, Modern Trail DNA
Cotic’s journey began in 2003 with the Soul, a pioneering progressive geometry hardtail. The Soul redefined trail hardtails by leveraging Reynolds 853 steel to create a bike that was both remarkably tough and incredibly responsive and fun to ride. It was a genre-defining, award-winning bike, celebrated for its beautiful design and balanced performance.
The DNA of the Soul flows through every Cotic we create, and the Solaris is a direct descendant of this hardtail heritage. Decades of continuous development and refinement have culminated in a ride that is nuanced, engaging, and utterly thrilling.
Our extensive experience has resulted in what we believe is simply the best hardtail we’ve ever produced. And by extension, that makes the Cotic Solaris one of the finest steel hardtails available anywhere.
The renowned Reynolds 853 tubing creates a front end that is light, responsive, and remarkably robust. It incorporates our custom ride-tuned Ovalform top tube, which is key to the Solaris’s signature ride feel. The inherent compliance of the steel frame provides natural ground-hugging characteristics, maximizing grip and feedback even on seemingly featureless trails. This is expertly paired with our custom-sized and shaped heat-treated cromoly rear end, resulting in a frame that is incredibly light, exceptionally tough, and delivers an unparalleled ride experience.
Your Dream Bike, Built by Us in the UK
At Cotic, we’re passionate about building your dream bike. Every Solaris is assembled in the UK, starting from the frame up, allowing for complete customization.
Our stock specifications are meticulously curated, but they are just the starting point. Want tubeless tyres on your Silver spec bike? Easily done! Prefer a large-can air shock on your droplink full suspension bike instead of an inline model? That’s an option too. Want to add full colour-matched Hope components, including brakes? It’s just a click away, along with countless other possibilities. If you don’t see your desired customization on the order form, simply ask us.
When you contact Cotic, you’re directly engaging with the people who design the frames and will be hand-building your bike. We meticulously inspect, build, and package your Solaris in our award-winning bike boxes with the same care we would give our own bikes. Because we understand how important your new bike is to you. We build your bike, specifically for you.

Origin: Crafted in Czechia, Assembled in the UK
Cotic frames are conceived, designed, engineered, and rigorously tested by our dedicated team at our base in Chesterfield, UK. The Peak District, our local riding playground, provides the perfect proving grounds for developing world-class mountain bikes. Cy Turner, our founder and lead designer and engineer, spearheads the design process, and every Cotic frame undergoes extensive ride testing by our entire team and brand ambassadors. Our frames are fully certified and exceed the stringent ISO4210 safety standards through rigorous lab testing.
The Solaris frames are handcrafted and painted by Fort in Czechia. We chose Fort for their decades of experience in building high-end frames using our preferred materials, their exceptional finish quality, and their shared passion for creating beautiful bikes. We maintain a close collaboration with Fort to ensure every frame meets our exacting standards.
Each frame receives comprehensive anti-corrosion treatment before painting. After meticulous deliberation over colours, designs, and decals, the frames are painted to the highest standards, including a protective clear coat, followed by thorough quality control inspections. Upon arrival at Cotic HQ in the UK, we conduct further QC checks and prepare the frames for headset and bottom bracket installation.
As always, every complete Cotic bike is built to order by our team here in the Peak District, to your precise specifications. We build your bike, for you.
