Shimano has officially unveiled the EP810, the latest generation of its full-power eMTB motor, bringing significant upgrades in torque, power, weight, and smart riding features. The new DU-EP810 delivers 100Nm of maximum torque and 750W of peak power, marking a 17.6% and 25% increase over the previous EP801 generation. It operates on a new 43V system voltage and weighs just 2.3kg, a reduction of nearly 15% thanks to a magnesium motor housing and redesigned internal gearing.
A key design shift sees the motor flipped to the left side of the drive unit, with electronics positioned on the right. This compact layout improves ground clearance, exposes more cooling fins, and contributes to the weight savings. Shimano prioritized a balance of power, control, and efficiency over raw output, explicitly setting the upper limit at 100Nm and 750W “because a balance of power, control, ride feel, efficiency, and durability were prioritized over headline power numbers.” The brand’s long-standing philosophy is that an eMTB should still feel like a mountain bike when ridden, “not like a motorcycle,” preserving “the essence of cycling” so the system augments rather than replaces rider effort.
The EP810 introduces “True Auto,” a ride concept combining updated Auto Shift v3 and the all-new Auto Assist Trail+. Auto Shift uses upgraded sensors and an refined algorithm to automatically adapt gear changes to terrain, gradient, and cadence, with rider-adjustable preferences available via the Shimano Connect app. Trail+ Auto Assist intelligently varies pedal-assist levels in real time, scaling back power on descents and offering subtle traction control by detecting wheel slip or front-wheel lift. Both systems are designed to smooth the ride while remaining fully customizable—the rider can opt out of auto-shifting entirely and retain manual control via Free Shift or Di2 integration.
New hardware rounds out the package. A larger, color 2.2” top-tube display (SC-EN700) offers easy-to-read data, tactile buttons, and an optional USB-C charging port. A revised bar-mounted EC-EM810 display adds full color and expanded metrics. A wireless 3-button assist switch eliminates cable clutter. The system also debuts a faster D-Fly+ wireless protocol and new 720Wh internal batteries with 43V fast chargers (2A and 4A options), though both are not backward compatible with previous EP801 systems.
Shimano confirms the EP810 will debut on the Honda RN0 and a new Orbea Rise, with the company noting “interest across the industry” from other manufacturers. Because the drive unit’s shape and dimensions have changed, most brands will need to update frame designs; the EP810 will not fit existing EP801 frames without significant modification.
In the saddle, the EP810 feels noticeably punchier and more responsive than its predecessor. While the True Auto features can feel overwhelming initially, riders can tailor the experience through the app. The motor delivers ample power without sacrificing the natural feel of pedaling, reinforcing Shimano’s stance that an eMTB should enhance, not replace, the cycling experience.
