Ultracompact, light and smart system that creates a full range of new riding possibilities while making eBikes look & feel indistinguishable from high performance bikes. The latest innovations create the best support at any cadence, whether racing at top speeds or climbing up a mountain. X20 is designed to drive the rider and the whole industry forward.
With only 3.2 Kg of system weight, including drive unit, inner battery and head unit, the X20 System is the lightest eBike rear hub system on the market.
55 Nm of torque and compatible with the EU (25 Km/h) and US (20 Km/h) markets, the X20 drive unit is designed and assembled in Europe to reach a maximum performance level, completely eliminating the drag when maximum assisted speed is exceeded, not penalizing the rider.
New 350 Wh internal batteries which can be complemented with a 172 Wh Range Extender, delivering up to 200 Km Autonomy. Intelligent fast charging system up to 4A charging the battery up to 80% of its full capacity in less than 2 hours.
THE MOST NATURAL ASSISTED PEDALLING FEEL EVER
DUSTYAt Mondraker we refuse to sacrifice that natural pedalling feel on any of our electric models, and the DUSTY is no exception. That’s why we’ve collaborated closely with Mahle from the very beginning to implement our tuning philosophy to the system, thus achieving exactly the response we expect from the support the DUSTY offers you while riding.
The DUSTY's natural pedalling feel is one of its key features when it comes to managing the way you receive assistance from the Mahle X20 motor. Regardless of the level you select (there are 3 levels) there's no need to change the way you pedal as you’ll hardly notice the seamless transitions between each and every start and stop of the motor’s assistance. As such none of the 3 levels of assistance feel intrusive. Even in assist mode 3 (the maximum) we’ve maintained the same natural pedalling feel thus avoiding any unwanted power spikes.
ASSISTANCE BY MONDRAKER
‘WATTS ON DEMAND’The DUSTY has 3 levels of assistance, each fully configurable by the user through the MySmartBike application. We’ve collaborated with Mahle on the development of specific firmware to define the assistance characteristics of the motor for use on gravel bikes. As a starting point the objective we set ourselves was to simulate the effort made by the rider at all times, without the assistance of the motor exceeding the sensation of a natural pedalling feel. This is the concept that we call “WATTS ON DEMAND”.
We follow these three core principles:
Each level has 3 features which are fully configurable by the user:
As such level 1 has a continuous power contribution of 25%, level 2 reaches 50% and level 3 goes up to 200% (varying between 75 and 200% depending on the torque input by the rider). Unlike other systems, the Mahle X20's assistance is based on the torque (application of force) produced by the rider, rather than cadence. The assistance offered by the system is always proportional to the effort exerted by the rider, as if it were a power amplifier. The sensor that controls the power (torque) applied by the rider is located in the bottom bracket.
The 3 models that make up the DUSTY line-up share the same STEALTH CARBON AIR carbon fibre frame and the same Mahle X20 system with its internal 350Wh battery. There are 3 configurations available; DUSTY R, DUSTY RR and DUSTY XR.
