How long does the WHEELTOP EDS OX 2.0 battery last and how do I charge it?

The OX 2.0 battery delivers approximately 24,000 shifts per charge—roughly 60+ hours of typical riding. Charging uses WHEELTOP's proprietary magnetic charging cable (not USB-C); simply attach the magnetic tip to the derailleur port for a full charge in about 2 hours. The battery is user-replaceable via 4 screws with a 2mm hex key, so you can swap in a fresh pack without tools or dealer visits.
