Description

The Moustache Samedi 27 Off 2 Open is an electric mountain bike designed to handle gravel paths, forest tracks and light singletrack while remaining genuinely accessible. The hydroformed 6061 aluminium step-through frame keeps things simple when mounting and dismounting — a practical advantage on longer rides or when wearing everyday clothing.

Power comes from the Bosch Performance Line motor (BDU33, 75 Nm), part of the Bosch Smart System ecosystem. It pairs with the Bosch Intuvia 100 display and a Bosch LED Remote Bluetooth handlebar controller for smooth, responsive assistance management. The Bosch PowerTube 500 Wh battery sits vertically inside the frame, keeping the centre of gravity low and the silhouette clean, with a range of up to 98 km under favourable conditions.

Gearing is handled by a Sunrace CSMS8 11-speed cassette (11-46T) and a Shimano Deore RD-M5120 rear derailleur — a versatile setup that handles both flat sections and steeper ascents without drama. Maxxis Forekaster 27.5 x 2.35 tyres grip well on loose and hard-packed surfaces alike, mounted on asymmetric Moustache 6061 aluminium rims with a 23 mm internal width for solid off-road performance.

Suspension duties are shared between the SR Suntour XCM ATB fork (100 mm travel) and an aluminium suspended seatpost with 40 mm of travel, smoothing out the bumps on more technical terrain. The bike comes backed by a 5-year Moustache frame and fork warranty and a 2-year warranty on Bosch electrical components.

Bosch Performance Line Gen 4 - 75 Nm

The accessible reference for electrical assistance without a false note. The 4th generation Bosch Performance Line with its 75 Nm of torque offers a smooth and balanced driving experience, designed for those who want to enjoy the electric bike on a daily basis without seeking performance at all costs. Compact and discreet, this engine integrates naturally into the frame and is forgotten while riding — until the moment you need it. The assistance is then there, direct and linear, to support your effort on flat sections as well as on slight urban climbs.

Bosch PowerTube 500 Wh

The main thing, well measured. The Bosch PowerTube 500 Wh is the ideal battery for those who want to benefit from electrical assistance without taking on more than necessary. With 500 Wh of capacity, it comfortably covers everyday journeys and local outings, while maintaining a contained weight which contributes to the liveliness and maneuverability of the bike. Integrated into the frame tube, it preserves the clean lines of the bike and benefits from natural protection against shocks and weather conditions. A simple, reliable and sufficient solution for the vast majority of urban and peri-urban uses.
