With the new 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 you push 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 you tackle the most challenging technical climbs with confidence.

You 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 to create the perfect setup for racing and riding.

The most exciting feature delivered with the new EP801 firmware update is the extended assist carryover for when you stop pedaling. This is a key race advantage, allowing you to stop pedaling for a moment in the middle of the most technical and challenging terrain while the motor continues your forward momentum. Now, you 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 you 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 you override 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 you can choose the perfect gear. AUTO SHIFT then resumes on its own for the rest of the descent.

The new firmware is available free to all EP801 bike owners. You’ll will need to visit your local dealer to have the firmware update applied. Any new EP801 bikes assembled after June 25 will roll off the assembly line with these new capabilities pre-installed at the factory.

An update to Shimano’s E-TUBE PROJECT Cyclist smartphone app will be released this fall and will allow riders to perform this firmware update and customize their EP801 setting on their own. Until then, please visit your local dealer to update your EP801 bike.
