The WabashRT is the ultimate terrain equalizer. This gravel/road bike is equally proficient on hard surfaces, dirt trails, and a variety of terrains. Every component on the WabashRT has be geared towards offering confident stability and responsive control on sometimes unforgiving terrain, most noticeably with the custom-crafted flared road handlebar. The fact this is a Power Assist Bicycle, means you can spend even longer on your favorite trail, or explore different trails than you normally could.

At center-stage is a Shimano GRX drivetrain connected to Yamaha’s center-mounted PWSeries ST motor, which offers five levels of Power Assist and a max speed support of 28mph. That is mounted to an all-aluminum frame and fork, which includes internal routing for all cables, offering a clean outside and better protection from the elements. The frame is already fitted with all mounting/wiring points for Yamaha’s optional front/rear fenders and rear rack. Stopping is handled by a powerful, reliable Shimano GRX disc brake system both front and rear.

The Quad Speed Sensor, integrated into the rear hub assembly, is another industry leading innovation found on the WabashRT. This sensor is constantly taking readings 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. All this is handled behind the scenes, so you can pay attention to the road ahead.

The tough, ergonomic interface of the Multi-Function Meter displays all the stats you need, such as speeds, battery life, and time, and to see what Power Assist level you are engaged in at a glance. The computer is controlled with a conveniently placed ergonomic switch that can be easily operated with riding gloves.

The WabashRT is one of the lightest bikes in its category, only 46.7lbs, and does not make any compromises in quality or features to get there. Lastly, it is equipped with a LED Headlight to help keep you safe on the road.

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