Yamaha Power Assist Bicycle Logo


The YDX-MORO 05 is a mountain/trail bike from the ground-up. It’s built off of Yamaha’s Dual Twin Frame. This e-bike strikes the balance of a playful, progressive feel while maintaining a stable handling characteristic for greater confidence inspiration. The integration of Yamaha’s new PW-X3 motor allows you greater range, and even the capability of riding to the trail.

At center-stage is a Shimano SLX 12-speed drivetrain connected to Yamaha’s compact, center-mounted PW-X3 motor, their lightest, most-responsive drive unit yet. The PW-X3 offers seven levels of Power Assist, including an AUTOMATIC and a push assist mode, and a max speed support of 20mph, to assist you through every situation with a smooth, natural feeling ride. The drive is mounted to Yamaha’s Dual Twin all-aluminum frame and RockShox Revelation RC front fork. Additionally, all cables are routed through the frame for better protection from the elements. The battery is protected by the bottom cage of the Dual Twin frame, further protected by a subframe battery jacket. When fine-tuning the different sizes offered, the unique stack and reach dimensions were created to maintain the advantages of low center of gravity and an always-active suspension of the YDX-MORO 05 through the lineup. Stopping is handled by a powerful, reliable Magura MT30 hydraulic disc brake system both front and rear.

The Quad Sensor System, with integrated speed sensor as part of the rear hub assembly, is another industry leading innovation found on the YDX-MORO 05. This system is constantly taking readings of pedaling power, the bike’s rolling speed, rpms of the pedals, and bike angle to better anticipate in realtime the adjustments needed to Power Assist levels to ensure a seamless, natural feeling ride through the duration of your trip. With the Quad Sensor System, the YDX-MORO 05 offers an Auto support mode, which cycles between ECO, STD, and HIGH modes. All this is handled behind the scenes, so you can pay attention to the trail ahead.

The YDX-MORO 05 is one of the lightest bikes in its category, only 51.1lbs, and does not make any compromises in quality or features to get there.

The motor system, battery, and frame are covered under a 3-year warranty. Yamaha also covers all components on the YDX-MORO 05 under a 1-year warranty.

More internal technology than your over-priced ergonomic office chair, the travel distance on this dropper post was specially selected for every frame size to match rider size with the trail's demands.

Bump osmosis technology

The long-travel and ultra-strong 160mm fork absorbs bumps like a sponge to increase riding confidence even on the most challenging trail terrain.

A little guidance never hurts

Directly bolted to the PW-X3 drive unit, this ISCG05 chain guide will help keep the chain in place even under the gnarliest conditions.

A thing of beauty is worth protecting

This burley and robust chainstay protector is proprietary design by YAMAHA engineers to protect the frame from chains lapping chips to your beautiful paint job.

Patented Dual Twin Frame

The combined hydroforming and forging construction techniques created in Yamaha's patented Dual Twin frame protects components and delivers the ultimate in handing and control.
