It\u2019s been four years since Shimano updated its electric mountain bike motor system, which is an eternity in this fast-moving space. The new Shimano EP810, which officially breaks cover today, closes the gap with competitors on power and torque, drops a good chunk of weight, and adds a handful of smart features, from automatic assist to a USB-C port for charging accessories.<\/p>\n

When the EP801 launched in 2022<\/a>, automatic shifting was the headline. Now, Shimano is letting the bike decide how much assist to give, too.<\/p>\n

More power, more torque, and less weight<\/h2>\n

The EP810 drive unit puts out up to 750W of peak power, up from 600W for the EP801 and 500W for the original EP8. That matches Bosch\u2019s current Performance Line CX, though it\u2019s still well short of the Avinox MS2<\/a>, which can briefly hit 1,500W in boost mode. In the US, e-bike definitions limit motors to 750W of power output, though motor companies have interpreted that limit in different ways. For now, it appears both Bosch and Shimano are treating it as a maximum.<\/p>\n

<\/div>\n

Torque gets a bump too, from 85Nm to 100Nm. Weighing 2.3kg (5.1lb), the new motor is 500g (1.1lb) lighter than the 2.8kg EP801. It\u2019s also more compact, which Shimano says makes it easier to integrate into frames and improves ground clearance. In addition, Shimano claims to have reduced the mechanical noise from the motor.<\/p>\n

Let the bike pick the assist level<\/h2>\n

A new Auto Assist feature reads the terrain and the rider\u2019s input and adjusts motor support on the fly. \u201cOn climbs, support increases in a controlled way to help improve traction and reduce the risk of wheel slip or front wheel lift,\u201d Shimano says. Support drops on descents and is kept to a minimum on flat ground to save battery. This is a big shift from early e-bike systems that felt unnatural, and it should deliver both performance and battery-life improvements.<\/p>\n

\"Black<\/a><\/figure>\n

Auto Assist lives in a new mode called Trail+, which suggests riders will still be able to choose an assist level manually using the new wireless SW-UT600-LR switch. It looks more like a shifter or dropper remote than a typical assist controller, and it can be mounted on either side of the bar.<\/p>\n

<\/div>\n

Pairing Auto Assist with third-generation Auto Shift on a Di2 drivetrain gives riders what Shimano is marketing as \u201cTrue Auto.\u201d<\/p>\n

A third hand for stalled climbs<\/h2>\n

It\u2019s tempting to gun it uphill on an e-bike in a high gear, but that generally results in a mid-climb stall in a gear that\u2019s too hard. When this happens, it\u2019s tough to get going again. With a new Lift & Shift feature, riders put the bike in walk mode, lift the rear wheel, and double-tap the assist-down button. The system then shifts into an easier gear, ready for the rider to start pedaling again.<\/p>\n

A related feature, Hill Hold, uses the motor to keep the bike from rolling backward when walk assist is on, so there\u2019s no need to hang onto the brake while securing your footing or getting set to pedal again.<\/p>\n

Shimano also added Assist Carry Over, which keeps the motor running for a moment after you stop pedaling. That should help when ratcheting through rock gardens or over ledges, and riders can adjust how long the extra push lasts. This feature sounds similar to what I experienced testing Specialized\u2019s S-Works 3.1 motor<\/a> and is key to making an e-bike pedal more naturally, which today\u2019s e-bike riders expect.<\/p>\n

<\/div>\n

Finally, a USB-C port<\/h2>\n

A new USB-C module plugs into the EP810 system and puts out 5V at 1.5A. That\u2019s enough to keep a phone charged on a long ride, and it should be enough to power a bike light, too.<\/p>\n

\"Alt<\/a><\/figure>\n

Shimano added a new top-tube display, the SC-EN700, for riders who want a clean cockpit. A new full-color handlebar display is also available.<\/p>\n

On the software side, there\u2019s a new Shimano Connect app for adjusting settings, updating firmware, and tracking rides. Shimano hasn\u2019t said whether it replaces the E-Tube Project app. EP810 also uses a new wireless protocol called D-FLY+, which Shimano says transfers data faster and more securely. The protocol isn\u2019t compatible with the original D-FLY, and it only works with EP810 and newer systems.<\/p>\n

Pricing and availability<\/h2>\n

Shimano hasn\u2019t announced pricing or a release date for EP810, saying only that both will vary by market. A new Honda e-bike announced earlier this week, the RN0, features the new EP810 system as does the updated Orbea Rise.<\/p>\n
