Moustache Dimanche 29 Gravel 2026: Test, Review, Pros, Cons, Performance, and Autonomy
The Moustache Dimanche 29 Gravel 2026 is a highly versatile E-Gravel bike, distinguished by the lightweight Bosch Performance Line SX motor system. It is designed to excel across asphalt, gravel, and light off-road exploration.
Moustache Dimanche 29 Gravel 2026: Build Quality and Frame
The bike features a robust 6061 T4-T6 aluminum frame with complete integration of the battery (Bosch CompactTube 400 Wh) and cabling. The design is optimized for versatility, accommodating tires up to 700x50 for maximum comfort and traction. A carbon fork and flexible seat stays contribute to effective vibration damping.
Moustache Dimanche 29 Gravel 2026: Assemblies and Componentry
The propulsion system is the Bosch Performance Line SX, providing a maximum torque of 55 Nm and a peak power of up to 600 W. This system is valued for its smooth, natural power delivery. The transmission is strictly single-chainring (monocorona), utilizing groupsets like Shimano CUES or SRAM Apex/AXS with wide-range cassettes. The bike is equipped with hydraulic disc brakes and high-volume Maxxis Rambler 700x50C tires.
Moustache Dimanche 29 Gravel 2026: Comfort and Handling
Comfort
Comfort is a key strength, achieved through the combination of the frame's damping properties and the high volume of the 50 mm tires. This results in a smooth ride over uneven surfaces and reduced long-distance fatigue.
Handling
Handling is described as agile and well-balanced. The lightness and smooth power delivery of the Bosch SX motor allow the bike to handle similarly to a non-assisted bike when above the assistance speed. It is effective on technical climbs and predictable when cornering.
Moustache Dimanche 29 Gravel 2026: Performance and Autonomy
Performance
Performance is suitable for gravel use, focusing on assistance during critical moments. The motor is quiet, and its output is progressive.
Autonomy
The 400 Wh integrated battery provides an estimated range of around 90 km under optimal conditions. The optional Bosch PowerMore Range Extender (250 Wh) is available to achieve a total capacity of 650 Wh for extended rides.
Moustache Dimanche 29 Gravel 2026: Pros and Cons
Key pros include its excellent versatility (road/gravel), superior comfort, optimal integration of the drive system, and the natural power delivery of the Bosch SX motor. Cons include the potential need for the optional Range Extender for very long mountain rides, the inherent higher weight compared to a muscular gravel bike, and the wider gear steps of the single-chainring setup compared to a double.
Moustache Dimanche 29 Gravel 2026: Advice and Alternatives
Advice: For long excursions or bikepacking, the Range Extender is highly recommended. Optimal tire pressure adjustment is crucial for maximizing comfort and traction on varied surfaces.
Alternatives: Competitors in the lightweight E-Gravel segment include the Specialized Turbo Creo SL (often more road-focused), the Cannondale Topstone Neo SL (focus on stability and lightness), and models using the highly silent TQ HPR50 motor system.
