The 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?
Colours are Gloss Orange, or Gloss Aqua.
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.
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.
Roadrat 9 Build SpecificationOur builds aren't completely fixed. The specifications above are more of a starting point. You can tailor your bike on the Go Custom program with any of the following:
All our pricing includes UK mainland delivery and we aim to ship same week as your order if possible. We can send you a bike anywhere in the world - the pricing and options are on the Order Form when you fill in your address details.
If you'd prefer, then we also offer our Factory Collection from our base in the Peak District. We can fit your pedals, make sure you're fitted up and comfortable and you can even go for an inaugural spin on your new bike if you like. Just put a note on your order if you'd like to take advantage of that and we'll book you in.
Specifications subject to change without notice. Because of this, bikes show in videos and photos are likely to feature a different spec to that currently offered.
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.
