The Xiro is the first-of-its-kind electronic dropper post and introduces an all-new way to ebike by automatically lowering the seat when you come to a stop, allowing you to place your feet firmly on the ground for improved stability, comfort, and control. Professional installation only. We do not recommend consumers install this product themselves. Please see your local dealer for installation. Once Xiro is installed, control is assigned by default to the left round button, rendering the horn function unavailable. On the Segway Myon, you have the option to reassign control to the right round button (originally used for the light). The MUXI does not offer an alternative control option. ✅ Compatibility Segway Myon Electric Bike Segway MUXI Electric Bike
