Yamaha PW-XM eMTB Drive Unit
With a maximum torque of 85 Nm and weighing only 2.6 kg, the PW-XM is Yamaha Motor's premium eMTB drive unit. Equipped with lightweight magnesium housing, produced using Yamaha's extensive casting know-how, this high-tech motor has the highest torque-to-weight ratio among Yamaha eBike Systems.
"Pure Ride" Development Concept
To accomplish the mission, the PW-XM carries in its DNA the "Pure Ride" development concept inherited from our X series of flagship drive units. The unit delivers 85 Nm of motor torque throughout a wide cadence range.
Mechanical parts and software settings come together for sharp response. The design choices create the distinctive Yamaha feature of providing instant support with full torque immediately after pressure is applied to the pedal, not after certain crank turns.
Optimized Pedaling Efficiency
The 128mm ISIS interface bottom bracket axle allows for an ideal Q-factor, ensuring maximum pedaling efficiency.
Innovative Magnesium Casting
Vast experience working with magnesium gives Yamaha an edge in developing heat management measures, ensuring consistent performance and high reliability. The high strength-to-weight ratio of magnesium material used in the motor housing plays a major role in achieving the low weight of 2.6 kg.
Manufacturing Excellence
The PW-XM pays homage to its birthplace: Mori-machi, Japan. Yamaha Motor Electronics factory, the world's longest-running eBike drive unit factory, prides itself on an unyielding commitment to quality achieved through the alignment of experience and refined autonomous processes. As a regional hub for mountain biking and cycling tourism, Mori-machi provides an ideal setting for the birth of the PW-XM.
