IN BRIEF
Shimano unveils the EP810, its new e-MTB motor: 100 Nm of torque, up to 750 W of power and 2.3 kg on the scales. Compared with the EP801, it gains 15 Nm and 150 W, and its weight drops from 2.7 to 2.3 kg. It comes with a 720 Wh battery, a D-FLY+ wireless protocol, a new app and the True Auto mode, which automates both the assistance, in Trail+ mode, and gear selection on compatible Di2 drivetrains. Two bikes already use it: the Honda RN0 and the Orbea Rise.

The Shimano EP810 gains 15 Nm and drops to 2.3 kg
Compared with the EP801, maximum torque rises by 15 Nm, to 100 Nm, and peak power by 150 W, to 750 W. The claimed motor weight drops from 2.7 kg to 2.3 kg. The housing is made of magnesium alloy, with integrated fins to dissipate heat better, and Shimano has reworked the internal architecture to reduce mechanical noise. The assistance keeps up with pedalling up to 160 revolutions per minute.
With these figures, Shimano places the EP810 in the “full power” motor segment. It nonetheless remains in the controlled-power category, capped at 750 W.
True Auto: automatic assistance and gear changes
Under the True Auto name, Shimano brings together two functions. AUTO SHIFT selects the gear on compatible Di2 electronic drivetrains, and AUTO ASSIST, new to the Trail+ assistance mode, automatically adjusts the assistance level. The new generation of AUTO SHIFT relies on a revised algorithm and on additional motion data.
The system also switches wireless protocol. Shimano is announcing D-FLY+, which it presents as faster and more secure than the original D-Fly. With the EP810 announcement, however, Shimano specifies that it only supports the new protocol from this generation onwards: D-FLY+ is not compatible with existing D-FLY systems. The Shimano Connect app arrives at the same time: it lets riders set up the system, record rides and manage firmware updates, and it includes an electronic bike lock.
A 720 Wh battery and new peripherals
The BT-EN827 720 Wh battery is designed to be integrated into the down tube. It weighs around 4.1 kg, measures 420 x 84 x 73 mm and runs at 43.2 V. The EC-EN834 charger charges it at up to 4 A, the EC-EN832 at 2 A.
In the cockpit, two displays are offered: the SC-EN700 and the handlebar-mounted SC-EM810, which shows, among other things, speed, range, assistance mode and the status of automatic shifting. The SW-UT600-LR wireless remote has three buttons and mounts on the left or right. A USB-C module, the EW-USB30-C, powers external devices at 5 V and up to 1.5 A.
Honda and Orbea already on board
At the time of the announcement, Shimano had not published the list of e-MTBs that will come with the EP810 as standard. Two models are already known: the Honda RN0 and the Orbea Rise, whose peak power is limited to 600 W.
