When you think of Yamaha, there’s a good chance that motorcycles or musical instruments spring to mind. But did you know that they claim to have invented the first electronic pedal-assist bicycle system in 1993? Since then, Yamaha has sold more than 2.5 million e-bikes and 4.5 million drive units worldwide. That’s a roundabout way of stating that Yamaha isn’t a newcomer to the e-bike world.

Both feature an all-new frame with an integrated battery and the first use of Yamaha’s PWSeries ST drive unit in the U.S. New Frame & Motor Design
Compared to the Yamaha Civante , which was their first Class-3 e-bike in the U.S., the Wabash RT and Crosscore RC get a big improvement in frame design. The hydroformed aluminum frame now features an internal 500 Wh battery stored inside the downtube and a mid-drive Yamaha PWSeries ST motor at the bottom bracket.
