RTS Mount for Shimano STEPs second battery on Ergo seat for 630Wh Battery
Mount to carry an additional Shimano Steps battery. Features TerraCycle STEPS battery rail and an ABUS lock mechanism. Includes Velcro security strap for extra peace of mind. Backwards compatible with 504Wh and 418Wh batteries. Does not include battery.
The holes on this are not spaced the same distance as the ICE seat support bars are set apart. Horizontal mounting on a set back bar works fine, as shown in the photos. If you must choose to mount it vertically, for some odd reason, buy the ICE version.
