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, intuitive ride feel.

Highlights

  • 85Nm maximum torque: confident power for technical climbs and loaded trails.
  • 250W continuous rated output: sustained performance across all terrain types.
  • 25kph assist limit: EU and Australian road-legal pedal assistance.
  • Four assist modes: Walk, Eco, Trail and Boost — each individually tuneable.
  • FREE SHIFT & AUTO SHIFT: pedal-less gear changes and automatic shifting via DEORE XT Di2 or CUES Di2.
  • E-Tube Project app: fine-tune power profiles, assist mode behaviour and firmware over Bluetooth.
  • Dual Rider Profile: two independent rider setups stored in the motor.
  • CAN & ACC ports: broad accessory and display compatibility via CAN bus architecture.
  • Cast aluminium housing: robust all-weather build at 3.0kg.
  • Over-the-air updates: future-proof firmware management via E-Tube Project.

Smart Integration

The DU-EP600 pairs with Shimano Di2 electronic drivetrains — including DEORE XT Di2 with HyperGlide+ and LinkGlide, and SHIMANO CUES Di2 — 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 over-the-air firmware updates.

All-Conditions Durability

Built around a rigid cast aluminium body, the EP6 is engineered for all-weather riding across trail, trekking and urban applications. The CAN bus architecture enables integration with third-party display and sensor accessories, while the ACC port expands system flexibility. Compatible with Shimano's second-generation battery management system for longer range and smarter energy management.

Compatibility & Fit

The DU-EP600 is a mid-ship position drive unit and requires a compatible e-bike frame motor pocket — consult your frame manufacturer for motor pocket and bottom bracket shell compatibility before purchase. It supports Shimano DEORE XT Di2 (HyperGlide+ and LinkGlide), SHIMANO CUES Di2, internal hub gear systems, and mechanical drivetrains. Compatible with Shimano EP6-series e-bike cranks (FC-EM600 and FC-E series) in 160, 165, 170 and 175mm lengths. Rated voltage: 36V DC. This is the 25kph-limited version for EU and Australian road compliance.
