The Roadrat fits into your life, for work and play. 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. The Roadrat will take you to work, to the shops, on holiday, to the hills, on adventures, or just to that quiet place where you get some headspace.

Bikes start from £899 for the stripped out Singlespeed, which is still equipped with our fabulous deep disc only wheels and Deore hydraulic disc brakes. If you're wanting gears, then you have two options: A traditional geared drivetrain Sora build (that's the British Racing Green bike in the Gallery below), or the Alfine8 hub geared bike (the Matte Orange bike in the gallery), both for £999. Brake feel and modulation are superb because we only spec hydraulic disc brakes. It's The Future. For just £349 you could buy a frameset and build your own dream machine.

All Cotic Life Bikes have big clearances for big tyres. Sure you can speed it up on 700x28c, but we supply the bikes with big volume 37c slicks. They roll really fast, but float over the potholes in the road and bumps in the trail.

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. Our bolt thru RB3 front fork keeps everything accurate and together with the strongest of hydraulic brakes.

All the fittings for two bottles, rear rack, full mudguards are included, and track end dropouts for regular gears, fixed, singlespeed or hub gear. Why limit yourself and your bike to just one thing?

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. It's fun, versatile, simple and tough as old boots.

New colour options coming soon.... Gloss Gunmetal (like the Escapade) and Gloss Hot Yellow... both with silver reflective decals.

What's New?

The Roadrat3 now has the larger diameter down tube from the Escapade to improve stiffness under load when you've got your bike singlespeed, or loaded up with luggage.

Also new are a lovely clean disc only layout, and a new RB3 9mm bolt thru axle fork with matching wheelset. This gives great stiffness to the fork, and the additional safety of the closed loop dropout allows us to move the disc mount back to the traditional rear fitment.

All our bikes are hand assembled to order here in Sheffield by Paul, Cy 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.

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.




Geometry and Sizing Chart

The chart is a guide to frame size for the latest version of the ROADRAT: Ultra Compact Geometry - Roadmeans that the frames are low and long. You'll probably need a 350mm 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.
