Automatic Support Mode for E-MTB Ride

The PW-ST's exclusively tuned Automatic Support Mode delivers optimal assist in settings ranging from trail riding to racing by choosing from the bike's three riding modes -Eco, Standard, and High- as conditions demand. The system reduces assist on level roads but boosts power on steep inclines to offer fine-grained assist feel that makes it seem like it's reading the rider's mind.

Riding Up Hill

Against the Wind

Accelerating

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 half way up the steepest of hills.
