Description

The Moustache Mardi 27.4 Open is a versatile electric bike designed for city commutes and unpaved paths alike. Its low-step frame makes it easy to mount and dismount at any stop — a practical advantage in urban riding, for cyclists who carry luggage, or for those who prefer not to swing a leg over a high top tube.

Power comes from a Bosch Performance Line Gen 4 motor (75 Nm), paired with a Bosch PowerTube 500 Wh battery neatly integrated inside the frame. The Bosch Purion 200 display keeps things straightforward, showing speed, assist level and remaining range at a glance.

The drivetrain centres on a Shimano Nexus internal hub (263% gear range, 30-tooth sprocket): gears are enclosed inside the hub, protected from weather and mud, requiring far less upkeep than an external derailleur. Hydraulic disc brakes (Shimano MT200 or Alhonga HJ-472) provide reliable, progressive stopping in all weather. The SR Suntour XCM32-ATB fork (100 mm travel, preload adjustment and lockout) smooths out rough patches.

Available in Gris Pierre (glossy grey) in sizes S, M and L.

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.

Bosch Purion 200

The main thing, without distraction. The Bosch Purion 200 is the control screen designed for cyclists who want to keep their eyes on the road. Compact and integrated directly into the handlebars, it combines control and display in a single unit — clean, readable and perfectly within reach. Its clear display shows essential information at a glance: assistance level, speed, remaining autonomy and battery status. No frills, no extras — just what you need to ride with confidence. Robust and weather-resistant, it faithfully accompanies every outing, whatever the weather.

SR Suntour, XCM32-ATB, NLO, réglage de la précontrainte et fonction blocage, 100mm de débattement

SR Suntour XCM32-ATB suspension fork with 32 mm stanchions for increased stiffness and precise handling on all terrains.

Ideal for cross-country MTBs, trekking bikes and versatile e-bikes.
