Aluminium is back, or was it ever gone? In addition to the Coboc, the Moustache Dimanche 28.7 is the only other E-road bike in the group test with an aluminium frame. Its silhouette – like the Cannondale Synapse NEO SE, which also relies on Bosch power – is quite imposing. Except for the drop bar, the look of the bike has little in common with your typical road bike, which is exactly how it was intended! The Bosch Active Line Plus motor is powered by a 500 Wh battery which swells the down tube to considerable dimensions, offering minimal clearance between the chainrings and frame. The bulky covers for the charging socket and the battery lock leave a similarly bitter aftertaste. In contrast to the Cannondale with its Bosch Purion display, Mustache rely on the newer Kiox module to display all relevant data and provide an intuitive remote control. Hidden on the bottom of the handlebar, the remote allows you to operate the motor without having to let go of the handlebars. The componentry also includes a mechanical Shimano ULTEGRA R8000 groupset with 160 mm brake rotors at the front and rear. The 700x32C Continental Grand Sport Race tires inflate slightly wider than the claimed width on the Moustache Just Carbon wheels, measuring 33.5 mm. Nevertheless, the frameset has enough clearance for tires up to 40mm wide. Our size L test bike weighed 17.41 kg and costs € 5,299.

One more thing
If the user-friendly and easily readable KIOX module could also navigate, it would be perfect.
Close call
There are only a few millimetres between the frame and the chain. It doesn’t affect normal function, but if the chain gets jammed in there, things will get fiddly!
Room for more
The generous tire clearance could happily be exploited with wider tires.
Less is more
The chunky covers aren’t the most appealing, neither visually nor haptically.

The Moustache Dimanche 28.7 in review

Thanks to its compact and central riding position, you can easily make yourself comfortable on the Mustache for many hours in the saddle. The saddle is only slightly higher than the flared and compact bars, which not only ensures a very upright riding position but also instils you with confidence. Due to the central position of the rider and the Bosch motor, the weight distribution is very well balanced, so the bike’s heft doesn’t have a negative influence on its handling. Every manoeuvre on the Dimanche is easy to control and very good-natured. Due to its weight, it feels stable on the road, not at all disturbed by crosswinds despite the Aero wheelset. The Continental tires offer good grip, but the large volume specced also provides most of the comfort on this bike.

Tuning tip
larger tires and a carbon seat post for more comfort

Fun E-road bike, travel E-road bike, high-speed E-road truck– call it what you like. With the Moustache, you’ll have a good time whatever you do!

While the carbon fork does dampen some vibrations, the stiff rear end transfers a lot of bumps directly to the rider. The wide Q-factor will initially be very unfamiliar to experienced roadies. However, you’ll soon come to realise that this bike hasn’t got any pretentions of being a regular road bike. You automatically start riding differently, taking in the experience rather than just focusing on pedalling. On flat terrain, the transition at the 25 km/h threshold is barely noticeable, similar to the Specialized. On slight inclines that you would usually ride a bit faster, the Moustache is limited by its weight, but thanks to the large battery, it shouldn’t be too much of a problem to rely on the support of the motor for the majority of the ride.


With the Dimanche 28.7, Moustache are targeting unbiased ebike fans, from beginners to professionals, who are looking for a practical and rock-solid bike that will instil you with confidence and make your ride that much more fun. With its versatile and playful character, there is nothing to hint at its weight – at least as long as the motor is engaged or you’re riding on flat terrain. The Moustache is not an E-road bike, but a fun-bike with drop bars!
