Racers Rejoice: Shimano Unveils EP801 Update

Shimano has just announced an update to their race-winning EP801 motor. The update will increase the power available to riders, how the motor assistance decreases when a rider reaches the motor’s max assistance speed, as well as how long the motor’s carry-over assist lasts once the rider stops pedaling.

The best part? This is available to everyone with an e-bike equipped with the EP801 motor. This is possible because the changes come in the form of a firmware update.

The biggest change this firmware update gives riders is more power in Boost mode. Shimano says riders will be able to reach a 400 percent assist ratio with ease—making the most of the EP801’s 600W max output. This means a more immediate response to pedal input and improved acceleration, as well as max torque on command.

For anyone who has ever been annoyed by the way their motor shut off once they reached its maximum assist speed, this update allows riders to customize the manner in which the power ends. Whether someone wants max power right up to cutoff or they want it to taper off to give them some warning, the motor’s behavior can be tailored to your preference.

Shimano says the most exciting new feature is the extended assist carryover. How long the motor continues to produce power after the rider stops pedaling can now be adjusted according to the rider’s needs based on terrain, race-specific needs or the rider’s riding style and what feels natural.
