The Cotic Flare is our 27.5" wheel, light and lively steel full suspension trail bike


The UK Made Flare combines the DNA of our Rocket enduro bike with the light, agile, subtle feel of our legendary Soul to bring a fun, fast, endlessly addictive ride into your life.

New for 2020, 135mm travel option via a longer stroke Cane Creek DB Air IL shock. Keeps that lively agile feel with just a little more bit hit capability

At heart the Flare is a technical trail tearaway. Lighter and easier to move around than our MAX 29er bikes, with more compact dimensions than our enduro focused Rocket, and droplink suspension brings more capability than our hardtails. The Flare ducks and weaves, pops and wheelies, scrabbles and clambers in and out of the tightest spaces. Optimised around 140mm forks, and sporting our radical Longshot geometry, it flows like water down singletrack, climbs beautifully, yet exudes confidence and pin sharp accuracy exactly when you need it in bigger or steeper terrain.

The Flare Reynolds 853 steel frame gives it a fleet footed feel and synapse quick, yet confidence inspiring handling. It scampers up climbs, and is massive fun whilst descending. A truly great All Round Mountain Bike.


Read the fabulous Singletrack review of the Flare:

"It’s fiendishly difficult to find any negatives about the Flare."

"The interplay between the hugely effective Longshot geometry, droplink suspension and the steel front triangle provide an energetic, almost hyperactive character."

Radical Longshot geometry keeps the bike stable through the rough stuff, planted in the corners and pinpoint accurate in the steep tech. Couple a super short 35mm stem to the optimised head angle and the bike really pushes you on, looking for every stump to boost off, rock to gap and berm to rail, keeping you connected to the trail while maintaining incredible poise and composure.

Reynolds 853

Reynolds 853 builds a light, lively and fantastically robust front end, and includes our custom ride tuned Ovalform top tube which helps to deliver that famous ride feel. The Flare uses Reynolds 853 super strong steel for it's made-in-the-UK front triangle. This includes our custom ride tuned Ovalform top tube which helps to deliver sublime trail damping and that signature Cotic feel; lively and fun, yet stable and controlled.

The frames' steel construction is compliant and naturally ground moulding, extracting grip and feedback from the trail where you thought there was none.

27.5" Wheels

The Flare is designed around the latest 27.5 x 2.6" wide trail tyres, with clearance to spare even with this monster rubber installed. 27.5" wheels are lighter, livelier and easier to accelerates than 29" or 27.5Plus wheels, with a more interactive feel. This is at the expense of slightly less stability and easy rollover on rockier, bumpier terrain. They also more easily package into a small frame - shorter chainstays, lower stack/head tube height - so the proportions suit shorter riders.

Cotic droplink high performance suspension
Cotic Droplink suspension is supportive and progressive, keeping the Flare's 125mm or 135mm travel options feeling lively and interactive, with grip to spare on the descents, support and traction on the climbs.

We Build Your Bike For You

All Cotic bikes are assembled in the UK from and frame up. We have set specifications, but these are just the start. Want the Silver spec bike with tubeless tyres? Easy! Want a big can air shock on your droplink bike instead of the inline? It's there too. Full colour matched Hope parts, and add the matching brakes too? It's a click away, and everything else in between. If it's not a choice on the order form, just ask.

When you contact us you are talking to the people who design the frames and will be building your bike. We check it and build and pack it in our award winning bike boxes with the same care we would our own bike, because we know how important it is. We build your bike, for you.

Is the Flare the bike for you?

If you like the idea of a suspension trail bike from Cotic, but want the versatility and easy rolling of 29er or 275 Plus wheels? Have a look at the FlareMAX.

Like your 27.5" wheels, but your ride a little faster and tougher? A little slacker and more enduro? You need the Rocket.

Maybe you like the liveliness and fun of the Flare, but you're more of a hardtail rider. You need the iconic, the original and best Soul.

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, and our Race Team. They are fully certified and lab tested in excess of the requirements of ISO4210 safety standards.

For this frame the majority of the production process happens right here in the UK! The skilled guys at Five Land Bikes in Scotland manufacture the Reynolds 853 front triangle in small batches, to their exacting standards. This is married to our proven rear ends and linkages from our excellent suppliers in Taiwan, as found across our droplink range. Much of the remaining machined parts are made by Superstar Components in Lincolnshire.

All the major parts of the frame are dip coated in manganese phosphate to prevent corrosion, before being painted using tough and durable automotive spec paint by the Five Land guys. The graphics on these frames are masked and painted, rather than stick on decals, for a seamless top quality look beyond anything you would normally expect on a production bike. After Five Land Bikes have completed this painstaking hand finishing process and their rigorous QC, the frame parts undergo further checking by us before assembly at our HQ in the Peak District.

As a final added extra, all UK made frames are Datatag'd from the factory. You will receive all your Datatag documents with your frame or bike when it's delivered.

As always, all complete bikes are built to order by us here at Cotic, to the exact spec of your choice. We build your bike for you.

The chart is a guide to frame size. Longshot Geometry means that the frames are low and long, with plenty of standover room. We recommend going for the size suggested for your height on the chart, and getting all the benefits of running a super short and responsive 30-35mm stem. It's a game changer. 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 or the dropper post bottoming out on the seat tube droplink pivot. 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.
