With two new mid drive motors – the PW-ST for sportive trekking and mountain bikes and the new top model PW-X2 for high-end E-MTBs – e-bike pioneer Yamaha Motor is again pushing its 'factory tuning' to the top – and is approaching the self-imposed development ideal 'Being one with the Machine' in an impressive way.
150% power – the new benchmark for the high-end E-MTB
Yamaha Motor’s PW-X already lived up to its strong reputation in terms of power output and stamina under more intense riding circumstances. Now the updated PW-X2 makes the next step, delivering even more – and more natural – support out there on the trail. The now implemented Quad Sensor System uses a fourth sensor to detect the angle of climb or descent, in addition to the hitherto existing speed, cadence and torque sensors.
Together with a fine-tuned Automatic Support Mode, the responsiveness of the drive system is further improved, resulting in a true natural ride experience: The motor acts as the rider’s best friend, delivering the necessary support in each and every situation on the trail. Ambitious E-MTB riders might appreciate the PW-X2’s characteristics even more when they are turning the cranks at a higher cadence (100rpm+), as this motor supports their pedal forces up to 50% stronger than its predecessor PW-X.

Update for light off-road bikes
For model year 2020, Yamaha Motor not only updated its flagship model but also the runner up system: PWseries ST is the new name (following the PWseries SE) – and this drive system benefits from the latest technologies in the same manner as the PW-X2. The PWseries ST features Yamaha Motor’s Quad Sensor System so that it can deliver optimized assist levels for all conditions despite weighing 100g less than the previous model. The unit also offers a broader assist range that can accommodate high-cadence pedalling.
Automatic Support Mode
For entry level or even more experienced riders it is sometimes no simple feat to shift gears, adjust seat height, and change ride modes at roughly the same time. The new Automatic Support Mode for the PWseries ST selects the right amount of assist power based on riding conditions. Whether starting from a stop, accelerating, braking, riding on a level surface, or climbing a hill, one can leave ride mode changes to the system and focus on shifting and braking.
Smoother hill starts
When set up in High Mode, the system modulates its support during the initial pedal strokes. This way it can prevent wheelies or rear wheel spin outs when starting on loose ground in steep terrain. The right power and modulation lead to stable control, and gives the rider peace of mind when starting from half way up the steepest of hills.
