PWseries ST Features

The PWseries ST features Yamaha's Quad Sensor System so that it can deliver assist optimized for all conditions despite weighing 100g less than the previous model. The unit also offers a broader assist range that can accommodate high-cadence pedaling. The tuning of the PWseries ST makes this drive unit the perfect all-rounder. Whether you're a newcomer to the sport or a veteran rider, and whether you're on- or off-road, the PWseries ST delivers fun, pleasant assistance for all riders.

Automatic Support Mode for all-round Sports and Trail

It's no simple feat to shift gears, adjust seat height, and change ride modes at roughly the same time. The Automatic Support Mode for the PWseries ST selects the right amount of assist based on riding conditions. Whether you're starting from a stop, accelerating, braking, riding on a level surface, or climbing a hill, you can leave ride mode changes to the system and focus on shifting and braking.

Natural and Powerful Assist Feeling

A powerful ride is the best thing about eMTBs, but a lack of control would leave you prone to wheelies during climbs and spinning tires on poor surfaces. The Yamaha tuning for the PWseries ST allows the drive unit software to handle power control. By combining power with stable control, this technology makes it easier for the rider to start with peace of mind even from halfway up the steepest of hills.
