When choosing an assisted electric bike for off-road rides and adventure, most of us tend to think of an eMTB, but there is another way! UK-based brand, Cairn has been perfecting the eGravel or E-Adventure bike for some time now, and with their latest release, the Cairn E-Adventure 1.0 Rambler Edition, this Fazua-powered platform is more capable than ever.

Those of you familiar with the Cairn range of bikes will instantly recognise the alloy frame, integrated battery and Fazua drive unit. It's a recipe that has served adventure riders very well, but while the new Cairn E-Adventure 1.0 Rambler Edition might look familiar, it's an entirely different beast.

The updated alloy frame boasts a revised geometry that mirrors what we have seen from mountain bikes over the past few years, adopting a longer, lower, and slacker approach. A 70-degree head angle, 74-degree seat angle, and 80mm BB drop might sound tame compared to modern eMTB numbers, but in the gravel world, this is pretty radical. For riders wanting to make the most of the aggressive new geometry and really push the limits of what a drop bar bike can do, the engineers at Cairn have ensured that the new frame is suspension ready. Riders can choose to fit a fork with between 30-40mm of travel without upsetting the geometry, and with a max tyre clearance of 700 x 45 and hydraulic disc brakes front and rear, the Rambler Edition promises to be fun even in properly rough terrain.

The updates don't stop there. The Cairn E-Adventure 1.0 Rambler Edition uses the all-new Fazua Ride 50 Street Drivepack and BB. This refined drive unit sees an increase in torque to 58nm, new cooling fins to manage system temperature and an increase in the unit's sensitivity by 70%. The result is a bike that can handle the steepest climbs while retaining Fazua's natural ride feel. The new motor, along with Fazua's Energy 250x battery, promises a near 10% increase in efficiency, too, meaning more time on the trail.


Cairn has worked with sister brand Hunt to build an E-Adventure-specific wheelset for the Rambler. The Hunt X Cairn E-Gravel Disc wheels have been developed specifically for the Cairn E-Adventure Ramber Edition and feature a steel axle and increased pawl contact area in the freehub to ensure long-lasting reliability. In addition, the alloy rims feature a 25mm internal rim width, which delivers better tyre profiles and being tubeless-ready, riders can run lower pressures for increased comfort and traction.

If all of this wasn't enough, the Cairn E-Adventure 1.0 Rambler Edition is also the lightest E-Adventure from Cairn to date. Working with Campagnolo, the Rambler uses the lightweight 13-speed Ekar drivetrain resulting in a low weight of just 14.3kg for the complete medium-sized build.

Those riders who intend to test the Rambler's adventure credentials will be happy to see the front and rear rack mounts, cable ports for front and rear lights, full fender mounts, Triple boss 'anything cage' mounts on each fork leg, and bottle cage mounts.
