Yamaha PW-ST motor for E-Bikes
Thanks to Yamaha’s Quad Sensor System™, the PWseries ST is able to provide optimal assistance in any riding situation, while being 100 g lighter than its predecessor. The cadence range for assistance has been further expanded to accommodate higher pedaling frequencies.
The features of the PWseries ST make it a perfect versatile e-bike. Whether you are a beginner or an experienced biker, on the road or off-road, the PWseries ST offers every type of cyclist the right support and lots of fun.
Automatic assistance mode for trekking and trails
Choosing the right gear, adjusting the saddle height, and selecting the assistance mode at the same time can be a challenge. That’s why the new automatic mode on the PWseries ST automatically selects the most suitable support for the riding situation. Whether you’re starting off, accelerating, braking, riding on flat ground, or climbing a steep hill, let the system choose the mode so you can concentrate on shifting and braking.
Powerful and natural assistance
The strength of Yamaha motors lies in their powerful yet controlled performance. The PWseries ST software perfectly controls the motor power, preventing wheelies or slippage. This ensures stability and allows for easy starts even on the steepest hills.
