How difficult is it to install the WHEELTOP EDS TX 1x12, and what tools do I need?

Installation difficulty is moderate and requires basic mechanical skills similar to mechanical derailleur installation, plus familiarity with electronic systems. You'll need a 2mm hex key (for battery access), standard bike tools for derailleur mounting, and access to the WHEELTOP app for pairing and calibration, which typically takes 30–45 minutes for experienced builders.
