Shimano officially released its EP810 e-MTB system on 6 November 2026, according to Bike Network’s South African coverage of the launch. For women watching the e-MTB space, the useful bit is not only the headline power: Shimano is also leaning into software that aims to make assistance, shifting and awkward trail restarts feel less complicated.
Bike Network reports that the EP810 drive unit weighs 2.3kg and delivers up to 100Nm of torque, with 750W of peak power. The system also gets a redesigned magnesium alloy cover with cooling fins, a more compact profile and revised internals aimed at reducing mechanical noise and improving heat management.
Software leads the update
The bigger change is the software layer. Shimano’s updated Auto Shift uses improved algorithms and motion sensing to select gears based on rider input and terrain, while still allowing riders to adjust their preferred cadence directly from the bike. In other words: clever help, not a tiny bossy mechanic taking over the ride.
Auto Assist is built into Trail+ mode and adjusts motor support according to gradient and riding conditions. Bike Network reports that the system increases assistance on climbs, reduces support on descents and conserves power on flatter sections. Shimano calls the combination of Auto Shift and Auto Assist “True Auto”, with the aim of reducing manual input without removing rider control.
Help for technical trail moments
There are also smaller trail-focused functions in the EP810 package. Assist Remain is designed to smooth power delivery when pedalling becomes inconsistent, while Assist Carry Over briefly keeps assistance going after pedalling stops. Hill Hold and Lift & Shift are aimed at steep restarts, with Lift & Shift allowing the rider to lift the rear wheel and automatically select a lower gear before setting off again.
EP810 is part of a wider Shimano ecosystem that includes a new app for system customisation, ride tracking, component updates and system lock. The launch also brings D-FLY+, Shimano’s new wireless communication protocol, plus a wireless three-button assist switch, updated display options, USB-C connectivity and a 720Wh battery.
Availability still to come
Bike Network’s report does not state South African pricing or retail availability, so this remains launch news rather than a buying recommendation. Still, EP810 matters because it points to where e-MTB systems are heading: not just more assistance, but more automated support around shifting, traction-sensitive terrain and those stop-start moments that can make a technical climb feel like admin with handlebars.
