The Yamaha PW-XM is the latest electric motor designed by Yamaha for pedal-assist mountain bikes. It offers improved performance and reduced weight compared to its predecessors. The PW-XM motor weighs 2.6kg, and Yamaha has achieved this weight reduction by utilizing magnesium in constructing the motor’s housing. Yamaha’s experience with magnesium in its Yamaha R1 supersports bike has influenced the material choice for this new eMTB motor.
In terms of performance, the PW-XM delivers 85Nm of torque, thanks in part to improvements in heat management. It is compatible with Yamaha’s existing drive units, specifically the PW-X3 and PWseries S2, which allows manufacturers to create different eBikes using the same chassis design. The compact design of the PW-XM further enhances this attribute. Additionally, the motor is compatible with all of Yamaha’s existing e-bike batteries and displays.
One notable feature of the PW-XM is its constant adjustment while riding. It incorporates Zero Cadence Technology and Automatic Support Mode, sensing technologies that automatically adjust the motor to ensure consistent power delivery. Yamaha refers to this as “Pure Ride.”
While it is highly likely that Yamaha will eventually use the PW-XM in its e-bike models, there is no official confirmation yet. Therefore, it is uncertain whether the PW-XM will be featured in an all-new Yamaha e-bike model or upgrade existing models like the Moro 07, launched last year.
Here are some of the key features of the Yamaha PW-XM:
- Weight: 2.6kg
- Torque: 85Nm
- Magnesium housing
- Compatible with PW-X3 and PWseries S2 drive units
- Compatible with all Yamaha e-bike batteries and displays
- Zero Cadence Technology
- Automatic Support Mode
- “Pure Ride” power delivery
The Yamaha PW-XM is a significant upgrade over previous Yamaha e-bike motors, and it offers several features that are sure to appeal to mountain bikers. It remains to be seen whether Yamaha will use the PW-XM in its e-bike models, but if it does, it could be a significant player in the e-MTB market.
