With the new STEPS MTB firmware update, you can now individually customize STEPS’ Boost and Trail power-assist levels to match your style of riding. Choose between high, medium and low support. Eco power-assist remains unchanged, continuing to offer the ideal balance of support and battery life. Using on-the-trail Bluetooth firmware, you can easily adjust your drive unit’s e-power on the fly. Learn more > shimano-steps.com/e-bikes/north-america/en/product-information/mtb/E8000-firmware-update
