Shimano EP810 motor: 100 Nm and 750 W of power for the e-MTB
In short: the Shimano EP810 motor is the new e-MTB system that Shimano presented on 6 November 2026. According to the manufacturer, it delivers up to 100 Nm of torque and 750 W of peak power, weighs 2.3 kg, has a magnesium housing with cooling fins and includes the "True Auto" automatic shifting. For bike park and enduro riders it means more push on technical climbs and easier riding.
What is the Shimano EP810 motor?
The Shimano EP810 motor is the Japanese brand's new generation of high-end motors for electric mountain bikes. It is part of a complete system: motor, battery, displays, wireless remote and mobile app. Shimano announced it on 6 November 2026 and, according to the manufacturer, its aim is to get close to the most powerful motors on the market in power without adding weight.
Key data of the Shimano EP810
| Feature | Data (according to Shimano) |
|---|---|
| Maximum torque | Up to 100 Nm |
| Peak power | 750 W |
| Motor weight | 2.3 kg |
| Housing | Magnesium, with cooling fins |
| Assisted cadence | Up to 160 rpm |
| New battery | BT-EN827, 720 Wh |

The manufacturer describes the motor as "significantly lighter" than the EP801, its predecessor. The exact weight savings vary depending on who calculates them, so it is best to wait for the technical sheets of each bike.
What is True Auto and what changes on the trail?
True Auto brings together two functions: the third-generation Auto Shift automatic shifting and Auto Assist, which adjusts the motor's assistance. According to Shimano, Auto Assist works in Trail+ mode. Auto Shift works with the Di2 XTR, DEORE XT, DEORE, GRX and CUES groupsets. In practice, the system decides for you when to change gear so that you keep a steady cadence, which is useful on rough sections where your hands are busy with the handlebar.
New features for everyday use
The system adds usage details that matter when riding with a loaded bike or pushing uphill:
- Hill Hold: in Walk mode, it stops the bike from rolling back on a ramp.
- Lift & Shift: in Walk mode, lifting the rear wheel and pressing twice to lower the assistance shifts down a gear.
- SW-UT600-LR wireless remote: three buttons and the D-FLY+ protocol, which is not compatible with the earlier D-FLY.
- Displays: the SC-EM810 colour handlebar display and the SC-EN700 top-tube display, plus the EW-USB30-C USB-C module for charging devices.
What it means for e-MTB riders
A motor with 750 W peak and 100 Nm puts Shimano in the conversation for enduro e-MTBs and bike park use, where riders look for fast climbs to alternative lifts or trail access. More torque with less weight also helps handling on the descent, because the centre of gravity is better balanced. Real performance data will depend on the tuning of each brand and the battery chosen.
