Shimano EP8

SpeedBox 1.3 for Shimano EP8 is the successor to the original tuning chips, redesigned from the ground up. These chips completely remove the 25 km/h speed limit, and the display shows the actual speed up to 23 km/h.

Looking for something even cooler? Check out the SpeedBox 1.3 B. Tuning for Shimano EP8 models with Bluetooth. These tuning chips allow you to adjust the speed limit and display the actual speed through the SpeedBox App.
