Description

The Moustache Dimanche 29 Gravel 4 EQ is an electric gravel bike built for riders who want genuine versatility without sacrificing day-to-day practicality. The hydroformed 6061 aluminium frame fully integrates the Bosch CompactTube 400 Wh battery and all cabling, giving the bike a clean profile. Up front, a full carbon fork with a tapered steerer handles trail buzz efficiently, while the Bosch Performance Line SX motor (55 Nm, 250 W) provides smooth, natural-feeling assistance up to 25 km/h. The Bosch Kiox 300 display — part of the Smart System ecosystem — offers colour navigation, ride data and a Walk Assist function.

The SRAM Apex Eagle 12-speed drivetrain, paired with an 11–50 cassette and a 44-tooth narrow-wide chainring, covers a wide range of gradients. Maxxis Rambler 700×50C tubeless-ready tyres with a supple casing roll efficiently on tarmac and grip confidently on gravel or wet paths. Comfort is further enhanced by the Moustache Antishock stem (10–20 mm of integrated suspension travel) and the EXA 860i dropper and suspended seatpost — a thoughtful system that removes the need for a suspension fork while keeping the ride smooth.

As an EQ build, the bike ships ready to ride year-round: full mudguards, an aluminium QL3 rear rack rated to 20 kg, Trelock Lighthammer front light at 80 lux and a Spanninga rear light — all powered by the main battery, with no extra wiring required. The frame carries a 5-year warranty, and the bike is manufactured in the Vosges region of France.

Bosch Performance SX - 60 Nm

Lightness reinvented. The Bosch Performance Line SX is the motor that blurs the line between electric bike and muscle bike. With 60 Nm of torque and a featherweight, it is discreet where others are essential - for a driving experience that remains above all natural, agile and pleasant. Designed for the thinnest frames and sportiest geometries, the SX is aimed at cyclists who want the electric boost without sacrificing the lightness or feel of the traditional bike. The assistance is lively and precise, perfectly dosed to enhance your pedaling without ever replacing it.

Bosch Compacttube 400 Wh

Lightness above all. The Bosch CompactTube 400 Wh is the battery designed for bicycles where every gram counts. With 400 Wh of capacity in a deliberately compact format, it is aimed at cyclists who favor the agility and maneuverability of a light bike, without giving up electric assistance on a daily basis. Its reduced format allows discreet integration into thinner frames and sportier geometries - where a standard PowerTube could not find its place. Ideal for urban outings and short to medium distance journeys, it offers most of the autonomy in the most compact format in the Bosch range.

Bosch Kiox 300

Information, without compromise. The Bosch Kiox 300 is the connected screen that strikes the right balance between readability, compactness and functionality. Mounted on the handlebars, it displays all the essential data of your ride on a clear and readable backlit screen - even in direct sunlight - without cluttering the cockpit. Connected to the eBike Flow app via Bluetooth, it provides access to software updates, personalization of riding modes and detailed monitoring of your performance. Easy to use, it is aimed at both urban cyclists and demanding hikers who want to keep an eye on their data without complicating their lives.

Abus
Bordo Big 6000/120 Black SH
The Abus Bordo Big 6000/120 is a 120 cm folding lock designed to give you real flexibility when securing your bike to a fixed point. Its articulated bar design wraps around posts, railings or bike racks far more easily than a traditional U-lock or cable, making it a practical choice for everyday urban use.
The bars are made from specially hardened 5 mm steel, providing strong resistance to cutting and twisting attempts. A dual-component extra-soft coating covers each bar, protecting your bike's paintwork from scratches — something regular commuters will notice and appreciate quickly.
The ABUS Plus cylinder is engineered to resist picking, a common technique used by experienced thieves. The lock ships with 2 coded keys and is compatible with the ABUS OneKey system, meaning you can order other ABUS locks keyed alike — one key for everything. The included SH bracket attaches to your frame via straps with no tools required, and allows front removal of the lock in a single, intuitive move.
With an ABUS security rating of 10/15 and German manufacturing, this lock meets the requirements of most bicycle insurance policies. It belongs to the Insurance-approved category at Kameo Bikes.

PD-EH500
The Shimano PD-EH500 are dual-sided pedals, with an SPD binding on one side for cycling shoes and a platform on the other for everyday shoes.

They weigh around 383 g per pair and come with multi-release SM-SH56 cleats, which let you unclip in several directions. Ideal for urban use, commuting and touring, they let you choose between cycling shoes and everyday footwear.
