Cotic's Hardcore Steel Hardtail

Super Tough SteelLongshot Geometry

Super Tough SteelLongshot Geometry

Some bikes are fast. Some bikes are tough. The BFe is both, and it doesn't ask you to choose.

This is Cotic's hardcore hardtail, built for longer travel forks, bigger terrain, and riders who want to point at something steep and commit. But here's the thing; despite the tough-sounding name and the aggressive intentions, the BFe has a beautiful ride feel. It is still a Cotic, after all. Forgiving, supple, springy – the signature steel character that defines every bike we build is fully present here, even in our most capable trail machine.

That makes it something rare. A hardtail that descends with complete confidence, climbs with ease, and pedals comfortably for hours. One bike that handles a smash-and-grab session on local trails just as naturally as a long day in the backcountry with a frame bag stuffed full of gear.

One Bike, Two Characters

The BFe features our Double Decker Dropout, a unique system that lets you run a full 29er setup or switch to a mullet 27.5 rear wheel. The frame angles and bottom bracket height stay identical either way. What changes is the character.

Run it as a full 29er and the BFe becomes a steamroller. Big wheels, long wheelbase, big mountains, serious chunk, it's the setup for riders who want to cover ground fast and make their full-suspension mates question their choices.

Switch to mullet and the attitude shifts. The 27.5 rear wheel position shortens the chainstay by 10mm, which doesn't sound like much until you're in a steep corner or flicking the bike off a kicker. Easier to manual. More agile in tight, committed terrain.

Same frame. Same angles. Two genuinely different bikes. You choose on the day.

Why BFe Makes Sense

  • You want a hardtail that doesn't flinch on serious terrain, but you also want to be comfortable on long days.
  • You like the idea of one frame that can genuinely change character.
  • You've come here from the trails and want a bike that can handle proper mountain terrain.
  • You want a Cotic trail hardtail, and you want it at a price that leaves room to build it exactly how you want.

Built on Experience

The BFe has been in the Cotic range since 2005 and is now in its seventh generation. It's still the benchmark for what a tough steel hardtail can be. Twenty years of trail feedback, iteration, and zero corners cut has led here. It's the most capable, most versatile hardtail we have ever made.

Longshot geometry

Radical Longshot geometry keeps the bike stable through the rough stuff, planted in the corners and pinpoint accurate in the steep tech.

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 35-45mm stem. It's a game changer.

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.

Angles and BB height DO NOT CHANGE with the different rear wheel sizes. The Double Decker Dropout accounts for the difference. The only change is the chainstay length, which is listed below

Bike Specs & Prices

Complete bikes from: £2399

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.

YOUR BIKE BUILT FOR YOU.

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!

Origin

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.

This frame is hand made in Taiwan by our specially selected framebuilder, chosen because of their vast experience with our favourite materials, and their top quality finish. They are the best in Taiwan for what we need.

Each frame is dip coated inside and out with zinc phosphate before painting, to prevent corrosion and ensure the best paint finish. After we've agonised over the colours, designs and decals the frames are painted to the highest quality including a protective clear coat, before extensive QC by our agent in Taiwan. Once the frames reach us in the UK, we carry out further QC, and prep the frames for headset and bottom bracket installation.

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