Shimano BM-E8016 Battery Mount Down Tube Type w/o key unit

Description

This is a mount that lets you install the little-known 630Wh Shimano down tube battery.

Most Shimano powered e-bikes with a 504Wh frame mount battery can be upgraded to 630Wh, provided there’s a bit of clearance above the existing battery, as the 630Wh battery is taller.
