Description
The Moustache Dimanche 28 Road 4 OPEN is an electric-assist road bike with an open frame, available for the 2026-2027 season in Noir brillant (gloss black).
Assistance comes from a Bosch Performance Line SX motor (55 Nm), paired with an integrated Bosch CompactTube 400 Wh battery, for a claimed range of 50-60 km. The Bosch Kiox 300 connected display, compatible with the eBike Flow app, shows all the key ride data.
The SRAM Apex XPLR 12-speed drivetrain delivers reliable shifting on all terrain. Braking is handled by SRAM Apex hydraulic disc brakes with 160mm rotors front and rear.
The full-carbon Dimanche 28 fork, with a tapered steerer, 12x100mm thru-axle and mudguard mounts, accepts tyres up to 700x45. Weighing 16.3 kg, the Dimanche 28 Road 4 OPEN is available in sizes XS, S and M.
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.
