SpeedBox 1.3 for Shimano EP8 | Speed Unlock Chip

The SpeedBox for Shimano's flagship EP8. Completely removes the 25 km/h assistance limit — maximum speed unlimited, real speed shown on the display up to 23 km/h. Toggle on and off via your lights: lights off = tuning active, lights on = back to standard.

Compatible with: Shimano EP8 and EP8 RS motors, plus Giant Revolt (to 35 km/h). Not compatible with Shimano EP801 or EP6 — 2023-onward bikes often run EP801, so check your motor model or ask us before ordering.

Which variant? Choose Standard if your bike has a free E-Tube port; choose +E-Tube Port if your ports are occupied — usually bikes with Di2 electronic shifting or a tube-integrated satellite on/off switch.

Genuine keyed connectors, reversible install, lifetime functionality warranty. Uninstall before Shimano firmware updates, then reinstall. Fitted while you wait at Grace and Pace, Alphington.

Important: private property use only — a tuned e-bike must not be ridden on public roads, paths or trails in Australia. Tuning may affect your bike manufacturer's warranty. The rider is responsible for complying with all applicable laws.
