Yamaha’s popular PWseries drive unit gets an upgrade for 2023 in the new S2, delivering a number of enhancements and refinements for e-bicycles in a variety of different segments.

The motor itself is lighter and more compact than the previous unit (16 percent smaller) while offering up to 7 percent more power. Volume is down 20 percent as well, opening up even more potential for e-bicycle manufacturers to design more effective frames, particularly when it comes to rigidity, handling, and rear-wheel traction.

A shorter bottom bracket helps to enhance pedaling efficiency and feel, while the improved bottom bracket axle interface increases rigidity. Although this unit can be suitable for all types of bike styles, you’re likely to see it predominate in mountain bikes, enduros, and other sport-focused bicycles.

Additionally, Yamaha introduced a new LCD meter it’s calling Display B, which will include a large 3-inch screen capable of storing information when shut off. It’s one-touch removable and still compact enough to let riders easily mount a smartphone alongside. It has a USB micro-B 1 A port to help keep smartphones charged. Yamaha describes it as a “ready-to-go” system, and it will be aimed primarily at casual riders looking for a simple unit that doesn’t take a lot of fuss to set up.
