Mondraker Dune R 2026 – Lightweight Carbon Electric Enduro Mountain Bike
The Mondraker Dune R 2026 combines the aggressive capability of a modern enduro mountain bike with the natural-feeling assistance of the Bosch Performance Line SX motor. Designed for riders who want to push harder on challenging terrain without the bulk of a traditional full-power e-MTB, the Dune R delivers a rewarding balance of descending performance, climbing efficiency and playful handling.
With a full Stealth Air Carbon frame, 170mm RockShox ZEB fork, 165mm of rear suspension travel and a mullet wheel configuration, the Dune R is built for steep, rough and technical trails.
Its compact 400Wh Bosch battery and lightweight motor system keep the overall package manageable, while SRAM Eagle Transmission gearing, powerful Maven brakes and aggressive Maxxis tyres provide the control required for serious enduro riding.
Whether you're tackling natural trails, technical enduro stages or a full day riding at your favourite trail centre, the Dune R delivers a genuine mountain bike riding experience with extra assistance when you need it.
Why Choose the Mondraker Dune R 2026?
Bosch Performance Line SX – Natural Power for Aggressive Riding
The Mondraker Dune R uses the Bosch Performance Line SX Smart System motor, developed specifically for lightweight electric mountain bikes.
Unlike traditional full-power e-MTB systems, the Bosch SX rewards an active pedalling style and provides its strongest performance at higher riding cadences. This creates an engaging riding experience that feels closer to a conventional mountain bike, with additional power available when climbing steep or demanding terrain.
The Bosch SX motor originally delivers up to 55Nm of torque, with compatible Bosch software updates offering increased torque of up to 60Nm and support of up to 400%, depending on the installed software and system configuration. The system also supports Bosch's intelligent riding modes, including eMTB and compatible eMTB+ functionality.
Motor assistance is limited to 25km/h in accordance with UK electric bicycle regulations.
Integrated 400Wh Bosch Battery
The Dune R features a Bosch CompactTube 400Wh battery, neatly integrated into the carbon downtube. This compact battery helps reduce overall weight and maintains the bike's slim frame profile.
The 400Wh capacity is designed to complement the efficient, lightweight Bosch SX system, making it suitable for riders who prioritise natural handling and an active riding style.
The battery is internally fitted and is not designed for routine removal by the rider. Charging is carried out through the bike's charging port.
Stealth Air Full Carbon Frame
The 2026 Mondraker Dune R uses Mondraker's advanced Stealth Air full carbon frame construction, combining strength, stiffness and reduced weight with a modern enduro-focused design.
The frame includes internal cable routing, an integrated Bosch drive system, oversized suspension pivot hardware, sealed bearings and a UDH-compatible rear dropout.
Mondraker's distinctive Forward Geometry creates a stable, confidence-inspiring riding position, especially on fast, steep and technical descents.
Updated Zero Suspension System – 165mm Travel
Mondraker's updated Zero Suspension System provides 165mm of rear-wheel travel, giving the Dune R the capability to tackle demanding enduro terrain.
The suspension platform is designed to deliver traction over roots and rocks, maintain control through successive impacts and provide support when pushing hard into corners or compressions.
The Dune R uses a RockShox Vivid Base rear shock, offering adjustable rebound and end-of-stroke support for controlled performance over challenging terrain.
RockShox ZEB Select – 170mm Fork
Up front, the Dune R uses a RockShox ZEB Select fork with 170mm of travel, a Charger RC damper and DebonAir+ air spring.
Designed for aggressive enduro riding, the ZEB offers excellent stiffness and control on technical descents. The fork provides adjustable low-speed compression, rebound and air pressure so riders can tailor their setup to their weight and riding preferences.
Mullet Wheels for Stability and Agility
The Dune R uses a mixed wheel-size configuration, with a 29-inch front wheel and smaller 27.5-inch rear.
The larger front wheel helps maintain momentum and improves rollover performance across roots, rocks and rough ground.
The smaller rear wheel allows more clearance and can make the bike easier to move around on steep, twisting and technical trails.
Combined with Mondraker's Forward Geometry, this configuration delivers an excellent balance of high-speed stability and responsive handling.
SRAM Eagle Transmission 12-Speed Drivetrain
The Dune R features a SRAM mechanical Eagle Transmission T-Type drivetrain, combining the SRAM 90 Eagle rear derailleur with a Trigger 70 shifter.
The wide-range 10-52T cassette provides suitable gearing for steep climbs and fast descents, while the robust Transmission design is engineered for precise shifting under demanding riding conditions.
The mechanical drivetrain offers straightforward maintenance without the need for electronic derailleur batteries.
SRAM Maven Base Brakes
Braking performance comes from SRAM Maven Base four-piston hydraulic disc brakes with 200mm Centerline rotors front and rear.
The Maven system delivers the stopping power required for modern enduro riding, giving riders confidence on steep descents and long technical sections.
Maxxis Assegai and Minion DHR II Tyres
The Dune R comes equipped with an aggressive Maxxis tyre combination.
At the front, a Maxxis Assegai 29 x 2.5 WT with MaxxGrip compound and downhill casing provides exceptional traction in demanding conditions.
The rear Maxxis Minion DHR II 27.5 x 2.5 WT features MaxxTerra compound and a DoubleDown casing, balancing traction, braking control and durability.
Both tyres are tubeless-ready and mounted on e*thirteen Grappler Core wheels.

How much torque does the Bosch SX motor produce?
The Bosch SX motor originally offers up to 55Nm of torque. Compatible Bosch software updates can increase this to up to 60Nm, depending on system configuration.
What battery does the Mondraker Dune R have?
The bike uses a Bosch CompactTube 400Wh battery integrated within the frame.

How far can the Mondraker Dune R travel on a charge?
Range depends on rider weight, terrain, elevation, assistance mode, cadence, temperature and trail conditions. The Bosch SX system rewards active pedalling and efficient use of assistance. The 400Wh battery does not have a guaranteed maximum mileage.
Is the Mondraker Dune R a full-power e-MTB?
No. The Dune R is a lightweight-assist electric mountain bike. Its Bosch SX motor is designed to complement rider effort rather than provide the same low-cadence assistance as a full-power Bosch CX system.
Is the 2026 Dune R full carbon?
Yes. The 2026 Dune R uses Mondraker's Stealth Air full carbon frame construction.
What suspension travel does the Dune R have?
The Dune R offers 170mm of front suspension travel through its RockShox ZEB Select fork and 165mm of rear travel controlled by a RockShox Vivid Base shock.
What does mullet wheel configuration mean?
Mullet refers to the use of a larger 29-inch front wheel and smaller 27.5-inch rear wheel. This combination is intended to provide front-wheel stability and rollover performance while allowing responsive rear-end handling.

Yes. Its e*thirteen Grappler Core rims and Maxxis tyres are tubeless-ready. Confirm whether the individual bike has already been converted to tubeless before riding.
Can the Dune R be ridden with the motor switched off?
Yes. The Dune R can be pedalled without electric assistance. Its relatively light weight for a long-travel e-MTB makes it more manageable than many heavier full-power electric bikes, although it will still require more effort than a typical non-electric enduro bike.
Is the Mondraker Dune R suitable for enduro racing?
The Dune R is designed for demanding enduro-style riding, with long-travel suspension, aggressive geometry, mullet wheels and robust components. Eligibility for organised e-MTB races depends on the specific event's rules.
What is the difference between the Dune R and Crafty Carbon RR?
The Dune R prioritises lower weight, natural handling and a more active pedalling experience with its Bosch SX motor and 400Wh battery.
The Crafty Carbon RR uses the more powerful Bosch CX system and a larger 800Wh battery, making it better suited to riders who want greater motor assistance and battery capacity.
