How difficult is it to install the WHEELTOP EDS GeX electronic derailleur?

Installation is moderately straightforward if you're comfortable with basic bike maintenance—you'll need a 2mm hex key, Phillips screwdriver, and torque wrench to mount the derailleur and secure the battery. Most riders can complete the installation in 30–45 minutes; if you're new to derailleurs, we recommend taking it to a local bike shop for proper calibration and limit adjustment.
