Designed from the frame up to offer the versatility needed to expand your riding horizons.
With the range of up to 120 kilometers on a single charge, the E-Adventure is ideal for fast (or not) gravel rides, multi-day and multi-surface bikepacking missions, singletrack exploration, or just ditching the car and taking on life's daily adventures by bike.
Versatile, Capable Frameset
Designed by riders, the E-Adventure frame geometry was built to offer comfort, control and confidence to keep you smiling over any terrain and any distance. Constructed from 6061-T6 Alloy for low weight and excellent durability, with clearance for up to 45mm tyres and ample mounting points for mudguards, luggage racks, and an anything cage, the E-Adventure frame is as versatile as it is capable. Load it up and explore, or just tack on that extra loop to your favourite ride.
Simple, Reliable Build Spec
The Fazua Ride 50 drive system was selected for its light weight, plug and play functionality and efficient, natural feeling pedaling support. The system offers three intuitive assistance levels, giving you control over your range, pace and riding style while adding just 4.6kg to the bike.
The easy to use 1x SRAM Rival groupset offers ample gear range for the steepest routes without the complication of a 2x drivetrain. Powerful hydraulic disc brakes with 160mm rotors keep you under control. The HUNT X Cairn E-Gravel Disc wheels have been developed especially for the Cairn E-adventure feature a steel axle and increased pawl contact area for a longer lasting hub. The wide 25mm internal Gravel X-Wide rims offer better tyre profile and allow for lower pressures, increasing your traction and comfort. Like all HUNT wheels, they are tubeless-ready and backed by a best-in-class support team.
Why settle for gear that is a trickle-down version of what the pros ride when there's a group that gives 100% of what you demand? Demands that are different, not less than, the pros'. Demands that change and evolve with your riding and performance, whether you're race ready or adventure ready. The SRAM Rival 22 groupset delivers immense performance across a broad variety of bikes and disciplines. The Rival 22 shift-brake levers offer comfortable textured levers with ErgoFit™ for improved grip and finger wrap. Whether you ride road, gravel, or cyclocross, Rival 22 is a group for every need.
The HUNT X Cairn E-Gravel Disc wheels have been developed specifically for the Cairn E-Adventure and feature a steel axle and increased pawl contact area for a longer lasting hub. The wide 25mm internal Gravel X Wide rims offer better tyre profile and allow for lower pressures, increasing your traction and comfort. Like all HUNT wheels, they are tubeless-ready.
The E-Adventure was built to take you acress many types of terrain quickly and confidently, which requires a versatile and reliable tyre. The Terreno Dry from Vittoria is the perfect pairing for the places the E-Adventure will take you.
Aggressive file-tread, or super low-profile knob design? The Terreno Dry bridges the gap between file treads and traditional all-condition treads. The key to this is the unique angled "fish scale" design that allows the centre tread to roll extremely fast, yet offer traction when loaded in cornering and braking. Add the transitional height mid and side tread and the Terreno Dry transitions as smoothly as it rolls.

For the E-Adventure, we continued to partner with the team at Fazua and spec their Ride 50 Street Drive Pack.
Its integration and natural pedal feel were exactly what we were looking for to complement our bikes. At only 4.6kg for the full system, it helps to create an incredibly lightweight and nimble e-bike. Furthermore, the system has no mechanical resistance if not in use, meaning you can choose to ride it as a normal/analogue bike without any drawbacks.
Choose from three levels of assistance or pedal without any help at all:
Breeze (~100 watts*)
Gentle constant. Like a strong tailwind even at low rider power.
River (~210 watts*)
Progressive and very sporty mode, for a smooth riding experience! The strength of the support precisely follows your own power. Give a lot - and get a lot from the motor.
Rocket (~250 watts*)
Aggressive assistance that helps you to tackle the very steepest climbs. This one will put a big grin on your face!
Ride 50 Street Drive Pack
Fazua’s all-new Ride 50 Street drive pack takes the original Evation system to the next level. The new drive pack features increased torque output, now putting out up to 58Nm of torque, helping tackle those technical or steep climbs. New cooling fins are present to manage system temperature.
The Ride 50 Street bottom bracket unit sees the biggest changes, with new torque and cadence sensors increasing the sensitivity of the unit by 70%. This will allow the system to further smooth out that natural ride feel that the Fazua Evation system has become known for.
The Energy 250x battery brings the final flourish of details to the build. The 250x offers the capability to turn your bike on and off from the remote (mounted in the top tube).
A new cap on the charging port adds a nice touch and reduces maintenance in the future.
Bike Magazine & Website Expert's View
Featuring all-new geometry, the E-Adventure aims to bring the rider more control without taking away the lively and responsive feel our bikes are known for.
The steeper 74-degree seat tube angle allows for better climbing on rough terrain, giving you a more efficient pedalling position, whilst maintaining all-important rear wheel traction. Combined with the slacker 70-degree head angle and increased 75mm trail, coming back downt the hill is a more predictable, stable and comfortable, experience, empowering the rider to let off the brakes and push the bike further.
The net result of the geometry changes is a riding position that puts the rider more in the bike than perched on top, achieved by increasing the bottom bracket drop to 80mm whilst maintaining a stack height with manageable saddle-to-bar drop.
The Rambler is the first Cairn E-Adventure to be compatible with suspension forks. If you ever do decide to add a suspension fork to your E-Adventure, we would like to make some recommendations based on our own testing:
- - 30-40mm of Travel
- 40-45mm Offset
- 700x45c (or larger) tyre
- If possible, upgrade to a larger front 180mm rotor
- 12x100mm spacing (keeps compatibility with stock wheel)
