PW-XM 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 DNA

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, creating the distinctive Yamaha feature of providing instant support with full torque immediately after pressure is applied to the pedal, not after a certain crank turn.

Pedaling Efficiency

The 128mm ISIS interface bottom bracket axle allows for an ideal Q-factor, maximizing pedaling efficiency.

Innovative Magnesium Casting

To step up its game, Yamaha leverages its extensive magnesium casting know-how acquired through years of motorsports applications. The high strength-to-weight ratio of magnesium material used in the motor housing plays a key role in achieving the low weight of 2.6 kg. Yamaha's expertise in working with complex materials also enhances heat management measures, ensuring consistent performance and high reliability.

Manufacturing Excellence

The PW-XM pays homage to its birthplace: Mori-machi, Japan. Yamaha Motor Electronics factory, located in Mori-machi, is the world's longest-running eBike drive unit factory, known for its unyielding commitment to quality through the alignment of experience and refined autonomous processes. As a regional hub for mountain biking and cycling tourism, Mori-machi provides a bicycle-loving atmosphere ideal for the birth of the PW-XM.
