Description

The Moustache Samedi 27 Off 4 Open 2026 is an electric mountain bike built for riders who want to explore technical trails without giving up everyday practicality. Its open-frame design in hydroformed 6061 T4-T6 aluminium makes getting on and off the bike effortless — a genuine advantage on long backcountry rides or for cyclists who want easier access to the saddle.

The Bosch Performance Line CX Gen 5 motor delivers 85 Nm of torque with a natural, responsive feel. Whether you're grinding up a forest track or picking your way through rocky switchbacks, the assist scales smoothly with your effort. The Bosch PowerTube 625 Wh battery sits horizontally inside the frame, keeping weight low and centred while protecting it from trail impacts. Assistance modes are managed through the compact Bosch Mini Remote BRC3300, so you never need to take your hands off the bars.

The SR Suntour XCR 34 fork provides 120 mm of travel with a handlebar lockout: open for descents and technical sections, locked for flat or uphill stretches where you want every watt to count. Maxxis Rekon 27.5 x 2.60 Tubeless Ready tyres mounted on 35 mm-wide asymmetric Moustache aluminium rims deliver traction and comfort across a wide range of surfaces. An 11-speed Shimano CUES drivetrain rounds out the package with a wide gear range to suit any gradient.

Backed by a 5-year frame warranty and 2 years on electrical and cycle components, the Samedi 27 Off 4 Open is built to ride — and built to last.

Bosch Gen 5 'Performance CX' - 85 Nm

The benchmark engine for riders who make no compromises. The 5th generation Bosch Performance Line CX is the trail engine par excellence: with 100 Nm of torque and assistance up to 25 km/h, it delivers raw and controlled power, capable of swallowing the most demanding slopes without ever flagging. Redesigned from the ground up, this 5th generation engine is more compact and lighter than its predecessors, while improving responsiveness. The response to pedaling is immediate and precise, with intelligent torque management that adapts to each variation in terrain - technical trails, steep climbs or chaotic paths, the CX knows no limit.

Bosch PowerTube 625 Wh

The everyday reference. The Bosch PowerTube 625 Wh is one of the most popular batteries in the Bosch ecosystem — and for good reason. With 625 Wh of capacity, it offers generous autonomy that meets the requirements of the vast majority of cyclists, from urban journeys to weekend nature outings, without the weight of a large capacity. Integrated into the frame tube, it is visually invisible while ensuring optimal protection against shocks and bad weather. Its extensive compatibility with Bosch Smart System motors makes it a reliable and proven basis, capable of making the most of intelligent energy management to adapt assistance to each situation.

BOSCH "BRC3300", Mini Remote

Control at your fingertips. The Bosch Mini Remote BRC3300 is the ideal complement for cyclists who want to keep their hands on the handlebars in all circumstances. Additional control panel for bicycles equipped with the Bosch Smart System and System Controller, it extends the available functionalities while guaranteeing safe riding. Connected via Bluetooth to the System Controller, it mounts easily on the handlebars and places the buttons within immediate reach of the thumb. Its dual-function buttons allow you to manage assistance modes, lighting and walk assistance without ever taking your eyes off the handlebars. Minimalist and discreet, it fits naturally into all types of cockpit for a clean, clutter-free result.
