Cairn E-Adventure Test Ride

Cairn E-Adventure Test Ride

Book a test ride and experience the full potential of the bike

Book an hour slot and we look forward to seeing you. Ordinarily, we would get the kettle on ready for your visit, but in these extraordinary times, things need to be slightly different to follow government guidelines and keep us all as safe as possible.

You are still more than welcome to enjoy a ride on the bike, but please only book a slot if you are not experiencing any coronavirus symptoms.

The Purpose

How do you feel about the idea of travelling twice as far on your bike for the same effort? Or how about a weekend away without the need for a car? Long-distance commuting without breaking a sweat? All of these (and more) are becoming possible with the advent of the e-bike.

The Cairn E-Adventure 1.0 was born to help you achieve this. We've been listening to devoted riders like you, and thinking on how best make the most of this whole new way of riding. Having e-assist on a bike will enable all of us to explore more of the paths-less-travelled and make it easier for people to choose bike over car more often, which can only be a great thing.

We’re super grateful that so many of you have declared such strong interest so early on so we’d like to offer you the opportunity to put your name down for a bike with a fully refundable deposit of just £299 required. Full price of the bike is £2989 and next deliveries of the bikes will be in January Week 1.

Please note: The final spec is as listed in the Full Specification tab with the possibility of a few minor updates. We have also been working on an updated paint job which you can see in the first images and the 360° image above.

Key Features

Equipped with the renowned FAZUA motor, ability to run both 700C and 27.5"/650B wheels (with clearance for up to 700x45C [650Bx2.2"] tyres) and mounts for both mudguards and panniers, it makes it the bike that can do it all. Imagine covering twice the distance for the same effort, enabling you to explore more ground every time you set off.

First Ride Review

"I finished my short time on the Cairn Cycles e-adventure grinning ear to ear and very impressed by the whole package."

First Look

"We caught up with the chaps from The Rider Firm at the Eurobike show. They’re the people behind Hunt bike wheels, but they were excited to show us something else they’ve been working on: a new gravel e-bike."

"A new concept with a strong pedigree"

"Why am I so excited about this? Basically, there’s all the ingredients there for what I think is good about bikes. It’s for adventure, it’s for taking the long way round to work, it’s for doing the shopping, it’s for leaving the car behind, or just choosing the car less often.

With the Fazua e-assist system, it’s an e-bike, or it’s not. You can forget to charge it and still ride to work. You can ride to work every day without being worn out. You can ride to work every day and rip your legs off. It’s a do a load of everything bike, and that gets me excited."
