Yamaha PW-X2 E-Bike Motor

Constant high power at high pedal frequencies

The new PW-X2 now delivers the necessary drive power even more targeted when the driver needs it. At a cadence of 100 rpm, it supports up to 50% more than its predecessor.

Automatic Support Mode for E-MTBs

The exclusively for the PW-X2 tuned Automatic Support Mode provides the optimal support in the entire range of trail touring to racing by automatically switching between the 3 support modes (Eco, Standard and High) depending on the riding situation. On flat roads is less support, on steep climbs, however, an extra portion of power delivered â that feels as if the system can read the thoughts of his driver.

High output

For Yamaha, being powerful means being able to quickly and reliably deliver the power the cyclist wants to use. Get the power you need, when you need it. In addition to âconstant high power at high cadenceâ, the PW-X2 offers the exclusive Extra Power Mode (EXPW). In EXPW mode, the device makes better use of the motor power thanks to the significantly improved cooling effects. It not only improves the support torque in all ranges; compared to conventional models, the support is maintained even at high speeds. In addition, it provides a robust support for the cyclists who recover from tight turns or challenging steep slopes. When you face a real challenge, just turn on the extra power!

Quick answer

High-quality mechanical components and control programs provide an unprecedented level of maneuverability. The reduced backlash of the ratchet mechanism and the lightweight design of the main moving parts such as the axle shaft and reduction gear contribute to a faster and more direct response to pedaling. In EXPW mode, Yamaha has fine-tuned the engine's power characteristics so that it retains massive power while delivering a refined blend of quick response and maneuverability.

Compact and lightweight

Making the drive unit more compact means not only reducing the overall weight of the bike, but also not compromising the ideal frame design. Yamaha has been able to lighten the design by using a hollow shaft with a thinner driven gear and reducing the case thickness by a remarkable 380 g, while reducing the volume by almost 13% compared to the first generation PWseries motor. Yamaha has also adopted the 128mm ISIS interface BB axle, usually used for MTBs, to meet the expectations of an authentic riding feel.
