Is history repeating itself? Yamaha Motor turned the global motocross racing scene on its head 20 years ago with its four-stroke crossers. Above all, the outstanding rideabilityì of the smooth four-strokes was decisive for their market success. And now Yamaha motor engineers have focused on the increasingly important and dynamically growing e-bike market worldwide.

With two new drive versions, the PW-ST for sporty E-Trekking and E-MTBs and the new top model PW-X2 for high-end E-Mountainbikes, Yamaha Motor is now driving development forward. Now the revised PW-X2 is taking the next step by combining its powerful support with an unprecedented natural riding experience on the trail. The technical data (250 W nominal power, 80 Nm in Extra Powerî mode and 70 Nm torque in the High / STD / Eco / +Eco stages) has remained the same, but the new PW-X2 promises its rider even more targeted delivery of well-dosed support, and at a cadence of 100 rpm, the PW-X2 now delivers up to 50% more power to the chain than its predecessor.

The new PW-X2 is equipped with a sensor and a sensor system.

More sensors for an even more intuitive riding experience

What is manifested inside the technology in the form of four sensors and finely tuned algorithms for drive control results in natural off-road riding behavior. The Quad Sensor System uses a tilt sensor to determine whether and how steeply the bike is riding uphill or downhill and links this measurement with the data from the previous speed, cadence and pedal force sensors. Yamaha motor engineers and test riders have used the Quad Sensor System and the Automatic Support Mode for the first time in the PW-TE drive from the 2019 model year and specifically adapted them to the desired support characteristics of each of their drive systems. Ambitious e-mountain bikers are likely to appreciate the new PW-X2 because it boosts their own pedal power even at high and highest pedalling frequencies and because the drive responds sensitively and quickly to the rider's wishes and the riding situation thanks to the newly integrated tilt sensor, especially in Automatic Support Mode.

For the 2020 model year, Yamaha Motor has not only revised its top model, but also the number two in the range: PW-ST is the new name - as the successor to the PW-SE series - and this drive system, like the PW-X2, benefits from Yamaha Motor's latest technologies: With the PW-ST, too, the Quad Sensor System ensures that the drive assistance is optimally dosed at all times, while 100 grams of weight have been saved compared to the predecessor model. In addition, the drive now provides support over an even wider cadence range, especially when the rider is cranking extra fast.
