Solaris is the hardtail for riders who want speed and simplicity without giving up composure when the trail turns serious.
There's a particular feeling you get on a well-built steel hardtail, a rhythm between you and the trail that full-suspension can smooth away. Solaris is built around that feeling. Light under power. Direct when you push on the pedals. Calm and planted when things get rough.
Why Solaris Makes Sense
Solaris delivers that balance, and then some. Reynolds 853 steel and Cotic Longshot handling means this isn't a compromise bike or a nostalgia trip. It's a serious machine that happens to remind you why you started riding.
Built on Experience
Cotic has been building this type of bike since the Soul in 2003. Twenty-two years of iteration, rider feedback, and quiet obsession with getting steel hardtails right has led here. It’s built from Reynolds 853, a proprietary heat-treated steel that is stronger than standard steel tube. This makes the frame lighter and more compliant without losing the toughness steel is known for. It’s hand made and finished in the EU. Solaris is simply the best hardtail we have ever built.
Radical Longshot geometry keeps the bike stable through the rough stuff, planted in the corners and pinpoint accurate in the steep tech.

Our new Cotic "C" Sizing tightens the gaps between sizing, and give you more options to size up or down as you wish.
Make sure you consider your leg length as well. If you upsize you might not be able to fit a longer dropper post due to the collar hitting the seat tube top. Maximum seatpost insertion for calculating dropper post options is on the chart.

We don't develop our bikes around a specific fork offset, we find that it's simply a preference down to the individual rider. If you'd like to learn more about this, Click Here
If you are unsure about that or anything else, drop us a line at size@cotic.co.uk and we'll be happy to discuss set up based on what you're riding at the moment and what seatpost you are planning to use.

Available as frame only from: £1199
Complete bikes from: £2847
Bikes are now available worldwide, with free shipping to UK, Ireland and mainland Europe.
We have several levels of stock build which are based around our favourite parts in builds you can trust. We never specify anything we haven't ridden, tested and enjoyed. However, just about everything in your build can be customised to help with fit (contact us if you need help) or to personalise your bike. Want a different fork? Shock? Brakes? Wheels? Tyres? Bars? Stem? Longer drop seatpost? Women's saddle? Men's saddle? Colour matched Hope components? No problem. It's your bike.
All the bikes are assembled from a frame right here in the UK by us. We can do everything from bare frame to complete bike: Send us your favourite saddle and grips to fit. Send us your wheels if you have a nice pair you want to use. There's no point you getting kit you don't want. It's wasteful. That gives you almost limitless options to customise and tune your bike to your needs. If you can't see an option you'd like on the order form, get in touch. We all know it's good to head off piste sometimes!
Tap on a build title below to see the default specification and price for that build... then hit the 'CONFIGURE YOUR BIKE' button to see all the customisations you can make to the build. When you select your country at the bottom of the form, sales taxes (VAT), pricing and shipping will automatically update for you. Once you're happy, order your bike!

Cotic frames are designed, developed, engineered and tested entirely by us at our base in the Peak District, near Sheffield in the UK. Our founder - Cy Turner - is the lead designer and engineer, and our frames are rigorously ride tested by everyone at Cotic. They are fully certified and lab tested in excess of the requirements of ISO4210 safety standards.
Solaris frames are hand made by Fort in Czechia.
A La Carte frames are painted to order right here in the UK, just a few miles from Cotic HQ. You can choose the base colour and decal colour from our extensive list of tried and tested paints, and you also have the choice of matte or gloss finish on whichever colourway you choose.
As always, all complete bikes are built to order by us right here in our workshop, to the exact spec of your choice. We build your bike for you.
Mountain Biking UK Head-to-Head Test

"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 it's 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 than was an XC mission, a trail outing or even hitting up some rougher enduro style tracks."
