The Yamaha PW-X Drive Unit (MPN: X1P-17061-11) is a high-performance mid-drive motor designed for e-bikes using Yamaha’s PW-X X1P1 platform. Known for strong climbing torque, fast engagement, and a natural pedal-assist feel, the PW-X series is widely used on performance e-MTB and trekking bikes.
This unit features the ISIS crank interface and is a direct replacement for motors originally equipped on many Haibike models. These units come direct from Alta Cycling Group and were originally built as replacement PW-X drive motors for Haibike e-bikes. Each drive unit is brand new, never installed, and intended for motor replacement or dealership service inventory.
PW-X vs PW-X2: The PW-X is the earlier high-performance Yamaha drive system and the correct replacement for bikes originally equipped with PW-X. The later PW-X2 introduced refinements such as expanded cadence support and updated control electronics, but the two systems are not interchangeable unless the bike was specifically built for PW-X2 from the factory.
Ideal for replacing a worn or failed PW-X motor or for stocking as a reliable shop-service spare.
