The Moustache Dimanche has been a mainstay of the French electric bike maker’s catalogue for many years now, but the 2026 models look to have taken what this classic can achieve to the next level.
Many gravel bikes come across as shy about the range of terrain they can cover, but the new Dimanche is unambiguous with its large tyre clearance, 29-inch wheels, carbon fork and accessory line up that begs for you to set this up as an all-weekend-long bikepacking rig.
Now, let’s take a look at the range-topping model – the £5,199 Gravel 6 build. In contact with the ground and giving you permission to grind up choppy gravel sections are a pair of supple 120 TPI Maxxis Rambler tyres clad to 29-inch wheels and with a 50mm width. This forgiving combination, paired with the 60Nm torque support of Bosch’s Performance Line SX will make weather-beaten ascents a lot less intimidating.
Despite this uncompromising kit, this is quite a sprightly electric gravel bike at only around 17.6kg in weight for the top spec.
12 Sram AXS gears spanning a 11 to 50-tooth range form the basis of your human-power propulsion and with a mid-weight 400Wh Bosch battery in the downtube there’s no reason why you cannot ride with no to light assistance all day long. Moustache has carefully considered the essence of the gravel riding experience and the spec sheet reflects the lengths it has gone to place the bike riding experience front and centre, with the electrics designed to be deployed only for the final miles, or steepest climbs on your journey.
Not immediately obvious, outside of the comfort-oriented geometry, is the lengths Moustache has gone to in creating a platform where you’ll be comfortable and fatigue-free over long rides. Integrated into the stem is a 20mm ‘antishock’ feature, which significantly takes the edge off small and mid-level vibrations. Paired to the high-volume tyres and the flared, relaxed posture promoted by the handlebars, the Dimanche doesn’t break a sweat at any time.
What perhaps appeals to us more than anything is how Moustache intend for this to be a full-on adventure bike. There are robust mounts on the fork that can be loaded up with bags and mudguards, making this the ideal backcountry getaway vehicle.
The four-bike Moustache Dimanche range starts a fair bit cheaper than the Gravel 6 build, with a flat bar Gravel 2 build delivered at only £3,199 and built with a Shimano CUES groupset instead of the premium SRAM kit.
