The Shimano STEPS EP6 DU-EP600 brings flagship-level pedal-assist performance to a wider range of e-bikes — delivering 85Nm of smooth, responsive torque in a compact mid-ship aluminium housing. Whether you're climbing technical trails or covering daily commutes, the EP6 matches power delivery precisely to your cadence and effort for a natural riding feel.

Highlights

  • 85Nm maximum torque for confident climbing and acceleration
  • 250W continuous rated power output
  • Pedal assist to 25kph (EU/AU speed limit compliant)
  • Lightweight cast aluminium housing — 3.0kg
  • Four assist modes: Eco, Trail, Boost, Walk
  • FREE SHIFT & AUTO SHIFT with Manual Override (Di2 compatible)
  • Fine Tune Mode via Shimano E-Tube Project app (Bluetooth)
  • CAN and ACC ports for expanded accessory connectivity
  • Over-the-air firmware updates via E-Tube
  • Dual Rider Profile support

Smart Integration

The DU-EP600 pairs with Shimano Di2 electronic drivetrains — including DEORE XT Di2 with HyperGlide+ and LinkGlide — to unlock FREE SHIFT (gear changes without pedalling) and AUTO SHIFT (automatic gear selection based on speed and cadence with manual override). All system settings are managed wirelessly through the Shimano E-Tube Project app, enabling fine-tuning of power profiles, assist mode behaviour, and firmware updates.

All-Conditions Durability

Built around a rigid cast aluminium body, the EP6 is engineered for all-weather riding. The CAN bus architecture enables integration with third-party display and sensor accessories, while the ACC port expands system flexibility for builders and OEM applications.

Compatibility & Fit

The DU-EP600 is compatible with Shimano's second-generation STEPS battery management system. It supports Shimano DEORE XT Di2 (HyperGlide+ and LinkGlide), CUES Di2, internal hub gear systems, and mechanical drivetrains. This is the 25kph-limited version for EU and Australian road compliance. Consult your e-bike frame manufacturer for motor pocket and bottom bracket shell compatibility before purchase.
