amd mountainbike Mondraker Zendit RR S e-MTB

The Mondraker Zendit RR S Bike is the result of Mondraker starting over. Rather than adapting an existing platform to house a new motor, the Zendit was engineered from scratch around the Avinox M2S drive system — the most powerful production e-MTB motor available, producing 130Nm of torque at the crank and 1,300 watts of peak power, with a Boost mode that pushes torque to 150Nm for up to 60 seconds when the terrain demands everything you have. This is not a bike for casual trail riders. It is for people who push into terrain that would stop a regular bike cold, and who want the climbing power to access descents that nobody else reaches.

The frame is Mondraker's Stealth Air full carbon construction, and the engineering here reflects input from the Mondraker Factory Racing DH development team. For the first time in a Mondraker production frame, 6-axis CNC machines handle drilling and finishing — a level of precision previously reserved for prototypes and race equipment. The pivot system is borrowed directly from the Summum DH frame, using single-size Enduro Max bearings throughout with double rubber seals for extended service life. The one-piece Monoblock upper link and oversize 15mm axles complete a chassis that is built to handle the loads that 130Nm of motor torque generates, repeatedly, without flex affecting suspension sensitivity or component wear rates.

The Zero suspension platform has been fully revised to match what the Avinox M2S can output. The kinematics deliver 27% progression with the 205x65mm Fox Float X Factory Kashima shock — enough to use the full stroke under power without blowing through the travel — while anti-squat at sag sits at approximately 105%, keeping the rear end active under pedaling loads. Anti-rise at sag is approximately 99%, meaning braking forces have minimal effect on suspension behavior when you need traction most. The mullet setup — 29-inch front, 27.5-inch rear — is the standard configuration, optimized for the aggressive climbing and descending the Zendit was designed for. A flip chip converts the bike to full 29-inch wheels by adding 7mm of chainstay length, with no change to bottom bracket height or key geometry angles.

Design Benefits

1. Avinox M2S motor — built for this frame — 130Nm standard, 150Nm in Boost mode, 1,300W peak. The M2S was developed in parallel with the Zendit chassis, not retrofitted into it. The result is a drive system and frame geometry that work as a single engineered system rather than a compromise between two independently developed products.
2. DH-derived pivot system and 6-axis CNC manufacturing — The Summum DH-spec pivot hardware, MAX capacity sealed bearings, and 6-axis CNC machining bring race-level durability and precision to a production e-MTB. Double rubber seals on every bearing extend service intervals without requiring special tools or proprietary parts.
3. Revised ZERO kinematics for e-MTB loads — 27% progression, 105% anti-squat, 99% anti-rise: these numbers are calibrated for a bike generating 130Nm at the crank. The suspension stays active under power, resists brake-induced squat, and uses the full stroke without harsh bottom-out on consecutive hits.
4. Fox Factory suspension throughout — Both the Fox Podium GRIP X2 fork and Fox Float X Factory Kashima shock carry Kashima coating and Factory-level damping. Mondraker worked directly with Fox on shock tune specific to the Zendit kinematics, not a generic e-MTB setup.
5. SRAM X0 AXS T-Type drivetrain — The direct-mount T-Type rear derailleur eliminates the hanger entirely, which matters on a bike being pushed up technical terrain at full power. Wireless operation, 12-speed range, and the durability of the T-Type interface make this the right drivetrain for sustained hard use.
6. Mullet with flip-chip versatility — The standard 29/27.5 configuration is optimized for the Zendit's geometry and intended riding. The flip chip option for full 29-inch wheels adds 7mm of chainstay without touching bottom bracket height or key angles — a clean implementation that doesn't compromise the base setup.

Final Take

The Zendit RR S is a new bike in the truest sense — not a refresh, not an update to a previous platform, but a ground-up design that exists because the Avinox M2S motor required it. At $12,999, the RR S brings full Factory suspension, SRAM X0 AXS T-Type, and DH-spec frame engineering to a bike capable of climbing anything and descending with confidence that most e-MTBs can't approach.
