The NEW Roadrat: Swift and Rugged Flat Bar Flyer

Road, Gravel, Commute, Adventures

Faster than a mountain bike on the road, way more fun and versatile than a traditional road bike, the Roadrat is your perfect 'other' bike. A Life Bike. Cruise into work or head for the hills. Go on holiday, or to the shops. Go on adventures, or get some headspace.

It was born of a desire for something swift and rugged to take on the rapidly crumbling tarmac of the urban landscape, but also up for disappearing for a few days with nothing but your sleeping bag and mat for company. We melded our iconic mountain bike fit and handling with fast road features and rigid forks.

All Cotic Life Bikes, including the Roadrat have big clearances for big tyres. We supply the bikes with big volume 700x37c slicks, or the latest WTB Road Plus 650b x 47c tubeless tyres. They roll fast, float over the potholes in the road and bumps in the trail. They give you comfort, control and a whole tonne of fun.

The bike is disc brake only, because we have always considered disc brakes to be the best, strongest, safest option for road or offroad riding. It's in the DNA of the Roadrat, right from the original 2006 version - one of the first road bikes to feature disc brakes.

Our brand new RB4 front fork moves to aluminium/carbon hydrid construction to keep the weight down and comfort high. A 12mm thru axle keeps everything accurate and together with the strongest of hydraulic brakes.

All the fittings are there for two bottles, rear rack, and full mudguards. Cotic Dogsbody track end dropouts let you do almost anything; regular gears, fixed, singlespeed or hub gear. Why limit yourself and your bike to just one thing?

Complete bike options

Bikes start from £899 for the stripped out Singlespeed, which is still equipped with our fabulous Deep Dish Disc wheels and Deore hydraulic disc brakes.

If you're wanting gears, then we have plenty of options to cover all the bases: The Roadrat 11 and Roadrat 9 offer simple, light, intuitive single shifter drivetrains based around wide range mountain bike style cassettes. The Roadrat Alfine 11 offers the same benefits plus the reliability and weatherproofing of an internal hub gear.

If you need a really wide range of gears for long days, or loaded up with luggage, the Touring build with double chainset 2x9 Sora build is the one to go for.

Brake feel, power and modulation are superb on all the bikes because we only spec hydraulic disc brakes. It's The Future.


Frame Options

For just £499 buy yourself a frameset and build your own dream machine.

Colours are Gloss Orange, or Gloss Aqua.

Cotic Factory Collection

We now have a Factory Collection option on the bikes. Come down to our base in the heart of the Peak District, and we will set up your bike, the suspension, fit pedals, get you all comfortable. You can even take your new Cotic out on its maiden voyage around our demo loop, straight from our workshop door.

Just tick the Factory Collection option on your order and we will look forward to seeing you. We'll contact you once we have received your order, and arrange a day that suits you for your visit (Monday - Friday).

What's New?

Following our customers' feedback, the Roadrat4 now features a tapered head tube with integral headset cups running into our brand new RB4 aluminium/carbon tapered steerer fork. Super clean, smooth looks. Light, comfortable and accurate ride from the carbon fork legs and 12mm thru axle hub interface. Tapered steerer means greater handling precision and many more options should you wish to change your fork at a later date.

The small and medium frames now feature shorter seat tubes and lower top tubes for better stand over clearance on those sizes.


Frame & Fork Specifications

Complete Bike Specifications

All our bikes are hand assembled to order here in Sheffield by Paul, Cy, Will or Richard. If there's anything on the spec you're not sure about, or don't need, give us a ring to discuss. We'd much rather leave something off you don't need and charge you a bit less than waste a perfectly good part you'll not use when we can put it on someone elses bike. Better for you, better for us, less waste, so better for everyone.

Geometry and Sizing Chart

The chart is a guide to frame size for the latest version of the ROADRAT:  Ultra Compact Geometry - Road  means that the frames are low and long. You'll probably need a 330mm seatpost due to the compact sizing, and as a guide, the top tube lengths are identical to our MTB frames if you're coming over from our mountain bikes. You lot are just too different to say for sure, so 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.
