Shimano has named and detailed the EP810, a redesigned generation of its EP8 e-bike motor. Shimano lists 100Nm of torque, 750W peak power and a claimed weight of 2.3kg, alongside updated automatic shifting, assist functions and system components. The Honda RN0 and a new Orbea Rise are identified as bikes using the motor, but wider adoption and availability details remain unclear.
Shimano has identified its latest EP8 e-bike motor generation as the EP810, giving the redesigned unit specifications of 100Nm of torque, 750W peak power and a claimed 2.3kg weight. The announcement matters to e-mountain-bike riders and manufacturers because the motor pairs higher output and a lighter housing with new automatic shifting and assist features, rather than competing only on peak power.
Shimano describes the EP810 as a substantial redesign of the previous EP801 generation. According to the company’s specifications reported by Bikerumor, the motor delivers up to 100Nm of torque and 750W of peak power. A revised motor orientation makes the unit more compact, while a magnesium housing cuts weight by almost 15% to a claimed 2.3kg. Shimano also says the new motor is quieter, though the source material does not give a measurement or testing method for that claim.
The new system’s software and controls are grouped under True Auto. Shimano says updated third-generation Auto Shift uses revised sensors and an algorithm to better match gear changes to riding conditions. Riders can adjust a preferred cadence within a limited range through the Shimano Connect app. The new Auto Assist feature, including a Trail+ mode, adjusts assistance based on inputs such as cadence, rider effort, speed and terrain gradient.
Shimano also lists hill-start assist, a Lift & Shift function for changing gears from a standstill, and Free Shift among the system features. New hardware includes a top-tube display with a color screen and optional USB-C charging, a wireless controller, and updated batteries and chargers. Bikerumor reports that the Honda RN0 and a new Orbea Rise use the EP810; Shimano itself told the outlet that it was seeing interest across the industry but did not identify other brands.
A Different Measure of Motor Performance
The EP810 gives bike makers a new option in the full-power eMTB category, with higher stated output and lower claimed weight than its predecessor. Its relevance is not limited to the headline figures: a more compact motor may offer additional ground clearance, while updated assist and shifting functions are intended to make power delivery and gear changes easier to manage on varied trails.
Shimano’s stated ceiling of 100Nm and 750W also places the launch in a market where some competing motors advertise higher output. The company says it prioritized a balance of power, control, ride feel, efficiency and durability over headline numbers. Whether riders and bike brands prefer that approach will depend on real-world performance, the bikes built around the motor and how the automatic features work for different riding styles.

How EP810 Builds on EP801
The EP810 follows Shimano’s EP801 as the next generation of the company’s EP8 motor platform. Bikerumor had earlier reported key specifications in connection with the Honda RN0; the newer report adds the EP810 model name and further details about the motor and its supporting system. Shimano continues to position EP8 as its top e-bike powertrain.
The new features reflect Shimano’s stated aim of coordinating assistance and shifting with a rider’s effort and trail conditions. Its representative told Bikerumor that the output limit was set to preserve what the company calls the essence of cycling, rather than make the motor feel like a motorcycle. That is Shimano’s design rationale, not an independent assessment of the EP810’s ride feel.
Pricing, Availability and Adoption
The report does not specify when EP810-equipped bikes will go on sale, how much they will cost, or whether the motor will be available as a standalone replacement for existing systems. Shimano has not named most interested bike brands. The Honda RN0 and a new Orbea Rise are cited as adopters, but the source does not provide complete model specifications or market-by-market availability.
Some performance claims also need real-world context. The listed 750W figure is peak power, not a stated continuous output, and the report does not describe the conditions used to measure it. Shimano’s claims about reduced noise, control and efficiency are not accompanied by comparative test data. The source also notes that the new D-Fly+ wireless protocol is not backwards compatible, but does not detail which existing components will or will not work with the new system.
More Bike and System Details
The next useful details will come from bike makers adopting the EP810, including complete bike specifications, prices and delivery dates. Riders will also need compatibility information for displays, controllers, batteries and wireless components before comparing the system with earlier Shimano setups.
Further testing can clarify how the claimed weight and noise reductions compare with the EP801, and how well Auto Shift and Trail+ perform across different terrain and rider preferences. Until those details are available, the confirmed picture is a lighter, higher-output redesign with new software and peripherals, while its market reach and practical advantages remain to be established.
