Race-Specific Firmware Update for SHIMANO EP801* Systems Now Available using your E-TUBE PROJECT Cyclist app
Announced earlier this summer, the most recent firmware update for Shimano’s race-winning EP801 drive unit delivers exciting new features and more customization options to help you boost your race speeds and keep the momentum rolling longer through techy terrain.
Shimano is pleased to share that the firmware update is now available to all current EP801* riders and will be standard on all bikes built following the firmware’s release—most importantly, the update can now be applied using the latest version of Shimano’s E-TUBE PROJECT Cyclist app.
Developed with Shimano’s world-cup winning Yeti / Shimano EP Racing team and proven by Orbea’s OOLab and Rotwild Schwalbe Enduro teams, the new updates include the ability to deliver an even higher assist level that will easily achieve the maximum 400% assist ratio for Boost Mode; a customizable max speed cutoff progression; and extended carry-over assist when riders stop pedaling.
Together, these new features complement the 600 watts of the EP801 drive unit to deliver the most exciting, natural, and powerful E-MTB system for racing and riding.
With the new SHIMANO EP801 firmware update, the assist level of the system’s highest boost setting is now even higher, achieving the maximum 400% assist ratio with ease. That means a quicker response when the rider pushes the pedals, with maximum torque delivered when it’s needed most. Tested and proven on the EDR-E World Cup Power Stages, this new assist level is a game changer for race-winning efforts and will make everyday riding even more exciting, letting riders tackle the most challenging technical climbs with confidence.
Riders can now customize how the EP801 system cuts off power when the max assist speed is reached. Whether you want a more natural wind-down of power for a smooth cutoff or want to maximize the assist all the way to the cutoff point—the choice is yours. This is just another way EP801 delivers the most customizable system for riders to create the perfect setup for their racing and riding needs.
The most exciting feature delivered with the new EP801 firmware update is the extended assist carryover when the rider stops pedaling. This is a key race advantage, allowing riders to stop pedaling for a moment in the middle of the most technical and challenging terrain while the motor continues their forward momentum. Now, riders can focus on getting through tricky sections of trail smoothly – without losing momentum or balance.
The duration of this extended assist mode can be customized between short, medium and long, so riders can fine-tune the assist based on the riding terrain, race-specific needs, or by what feels most natural.
And, just as easily as the extended assist mode goes into action over rough terrain, it can just as easily be cancelled. The system automatically turns off the extended assist when the rider backpedals, providing ultimate control over speed and assist.
AUTO SHIFT also receives significant improvements after continued development with Yeti / Shimano EP Racing’s Mick Hannah, who is using this function in EDR-E race stages. This update supports more aggressive riding with faster shifts while braking hard or accelerating quickly.
Additionally, AUTO SHIFT will pause when the rider overrides the automatic shifting with a manual shift on a descent. This is crucial for setting up for scenarios like G-outs and rapid braking into tight corners with hard pedaling out of them where only the rider can choose the perfect gear. AUTO SHIFT then resumes on its own for the rest of the descent.
The new firmware is available to all EP801 bike owners and is now free to apply using Shimano’s E-TUBE Project Cyclist smartphone app (Version 5.3.4). The update will allow riders to deploy it and customize their EP801 settings independently. If you need help, visit your local Shimano Dealer by clicking the link below:
About Shimano
Shimano’s origins began in 1921 when Shimano Iron Works, the predecessor of Shimano Inc., was established by Shozaburo Shimano in Sakai city, Osaka, Japan. The first product was the bicycle freewheel, which, at that time, required the highest level of bicycle technology to produce.
By the 1950s the company was producing products such as external speed changers and internal speed changers (3-speed hub). The success of these products led to Shimano’s first overseas sales office, Shimano American Corporation (currently Shimano North America Holding, Inc.) in 1965, followed by Shimano Europe in 1973. The first overseas manufacturing base, Shimano Singapore Pte. Ltd., also opened in the same year.
In 1991, the company name became Shimano Inc. Its headquarters remain in Sakai, the city of Shimano’s birthplace. Shimano is dedicated to helping its customers get closer to nature, supporting people to realize their dreams and create new lifestyles. That comes with the desire to create outstanding cycling products and apparel.
Shimano Inc. has a wide range of functions, including planning, development, design, manufacturing, and various other support functions for supplying bicycle components as well as fishing tackle and rowing equipment.
