Shimano EP600

Summary

Shimano EP600 is a mid-tier mid-drive motor system designed for e-mountain and trekking bikes, offering much of the functionality and performance of the flagship EP800 system at a more accessible price point. It delivers 85 Nm of torque, integrates with Shimano’s E-Tube Project platform, and supports semi-automatic Di2 shifting, making it one of the most feature-rich motors in its class.

Overview

The EP600 system — also referred to as EP6 — represents Shimano’s most deliberate attempt to bring high-end e-MTB motor features to a broader range of riders. Positioned just below the flagship EP801, EP600 retains the same torque output and software architecture, while using a slightly heavier and less expensive aluminum motor casing. The result is a system that performs nearly identically on the trail, but is better suited to mid-priced e-bikes across the trail, all-mountain, trekking, and SUV-style categories.

Shimano designed EP600 to offer full support for Di2 electronic shifting, Auto Shift, and Free Shift functions when paired with compatible drivetrains. This puts it far ahead of other mid-tier motors in terms of drivetrain integration and system intelligence. Riders using EP600-equipped bikes can expect the same level of pedal-assist customization as with EP801 — via Shimano’s E-Tube Project app — but at a lower system cost.

Its versatility makes EP600 popular not just among trail riders, but also among urban commuters and trekking cyclists who want a strong motor with smooth assist and future-proof electronics. The motor supports CAN bus connectivity, wireless communication, and modular integration with Shimano displays, batteries, and sensors.

How It Works

The Shimano EP600 drive unit is a mid-drive motor, meaning it replaces the bottom bracket and transmits power through the bike’s drivetrain. This location allows it to leverage gear ratios for climbing and descending efficiency, and keeps the center of gravity low — key for mountain and trekking bike handling.

Core Specifications

  • Torque: 85 Nm (same as EP801 and EP800)
  • Power: 250 W nominal, with peak support well above under load
  • Weight: 3.0 kg — slightly heavier than EP801 (2.7 kg) due to aluminum shell
  • Casing material: Cast aluminum (vs. magnesium in EP801)
  • Crank interface: Shimano-specific e-bike cranks
  • Q-Factor: 177 mm standard
  • Chainring mount: Direct mount system

Assist Modes

EP600 includes three customizable assist modes:

  • Eco – Prioritizes efficiency and battery conservation
  • Trail – Dynamically adjusts output based on torque and cadence input
  • Boost – Maximum support for steep climbing and acceleration

Each mode can be individually tuned in the E-Tube Project app, including:

  • Maximum torque output (up to 85 Nm)
  • Acceleration response
  • Assist start level

The system also supports dual rider profiles, allowing users to toggle between two different sets of assist characteristics on the fly — for example, a mellow touring setup vs. a trail-aggressive configuration.

Software & Connectivity

  • E-Tube Project App (Bluetooth): For customization, updates, and diagnostics
  • CAN bus: Allows EP600 to interface with third-party systems (e.g., displays, batteries)
  • Di2 Integration: Full support for Auto Shift and Free Shift
  • Firmware Updates: Delivered over-the-air or via dealer tools

Shifting Integration

When paired with Shimano’s Di2 drivetrain (such as LinkGlide or Hyperglide+), EP600 supports:

  • Auto Shift: Automatically selects gears based on speed, cadence, and torque
  • Free Shift: Allows shifting while coasting, using motor torque to move the chain without pedaling

These features dramatically improve riding flow, especially on variable terrain or in urban stop-and-go conditions.

Ride Characteristics & Value

EP600 was designed to bring the ride feel of EP801 to a wider audience, and in practice, it succeeds. It shares the same 85 Nm of torque and motor behavior, but is slightly heavier and marginally less thermally efficient due to the aluminum case.

Ride Traits

  • Smooth and proportional assist – especially in Trail mode
  • Responsive to cadence and torque changes – predictable and intuitive
  • Quiet operation – a hallmark of Shimano’s EP systems
  • Customizable ride dynamics – via E-Tube app
  • Excellent climbing performance – same torque as high-end systems

For most riders, the difference between EP600 and EP801 is negligible on the trail. The increased motor weight (~300 grams) is rarely noticeable during normal riding. This makes EP600 a standout value in the mid-drive market — especially compared to Bosch Performance Line mid-tier motors or older-generation Brose systems.

Ideal Use Cases

  • Trail e-MTBs – Full suspension bikes focused on balanced assist and control
  • Trekking / SUV bikes – Where range, smooth torque, and cargo support matter
  • Commuters / Utility riders – Looking for dependable motor performance without premium pricing
  • E-MTB Lite builds – Paired with smaller batteries for lighter feel without sacrificing torque

Notable Implementations

  • Norco Fluid VLT (2023+) – Trail e-MTB offering full EP600 power with 720 Wh or 900 Wh Shimano batteries
  • Cube Stereo Hybrid 120/140 (EP6 versions) – Mid-travel full suspension models focused on comfort and versatility
  • Giant Stance E+ – Entry-level full suspension e-MTB utilizing EP600 to keep performance high and cost down
  • Canyon Grand Canyon:ON – Hardtail e-MTB offering EP600 torque in a lightweight, simplified build
  • Devinci E-Troy Lite – Canadian all-mountain platform powered by EP600 and Shimano LinkGlide drivetrain
  • Merida eBIG.NINE / eONE.FORTY (EP6 versions) – Hybrid crossover e-bikes built for adventure touring and fitness
