Yamaha Bicycles Adds Two All-New YDX-MORO e-MTBs with PW-X3 Drive

Yamaha’s long history with pedal assist bikes continues with the introduction of two new full-suspension e-mountain bikes. The YDX-MORO 07 and YDX-MORO 05 both come with Yamaha-specific features like the PW-X3 center-mounted drive unit, dual twin frame, and quad sensor system.

Yamaha claims the bikes deliver the “smoothest assist delivery ever felt on a power assist bicycle in a lighter and more powerful complete package.”

“As the company that created the world’s first electrically power-assisted bicycle nearly 30 years ago, Yamaha is recognized as one of the world’s leading innovators in e-Bike technology,” said Rob Trester, Manager of Yamaha’s Smart Power Vehicle Division and the Yamaha Power Assist Bicycle group in the U.S. “We’re doubling down on the growing e-MTB market with the new MORO 07 and MORO 05 and offer our ‘Pure Ride’ feeling and race proven innovation to even more e-MTB riders.”

YDX-MORO features

The YDX-MORO bikes use Yamaha’s “lightest, smallest, most powerful drive unit to date,” according to the company. The PW-X3’s torque runs up to 85Nm. It delivers 250 watts of nominal assist and 500 watts of maximum assist. The PW-X3 has seven assist modes: ECO, Standard, High, MTB, Extra-Power, Automatic-Mode, and Walk Assist.

“The PW-X3 drive unit is 10% lighter and 20% smaller while producing more torque and the most ‘Pure Ride’ feeling of any e-MTB on the market,” said Drew Engelmann, Sales and Marketing Manager at Yamaha Power Assist Bicycles. “Yamaha’s passion for performance is driven by our racing heritage, and the YDX-MORO 07 and YDX-MORO 05 are true thoroughbreds for the next generation of e-MTB riders.”

Yamaha utilized a minimalist-style interface to control the electric components on the two bikes, with the aim of decreasing distractions that might lead to mishaps. The assist control switch is simple and partners with a 3-color LED interface to indicate which mode the rider is using. The electronics also connect via Bluetooth to Garmin Edge cycling computers.

Looked good until the last Spec. detail. 27 inch wheels only? Hope it’s a typo.

It’s not a typo. This bike should’ve been so much more for that price tag. Yamaha will hopefully catch up eventually, but they’re a bunch of moto dudes throwing their hats into a rapidly changing ring and are a few years behind the times.
