What the WHEELTOP EDS OX 2.0 wireless MTB rear derailleur offers: specs, cage choice, battery, app setup, pros and cons.
Quick answer: the WHEELTOP EDS OX 2.0 is a fully wireless electronic rear derailleur for mountain bikes. It supports 3–14 speed set in the app, is IP67 sealed, runs on a built-in 800mAh 7.4V (5.92Wh) battery with magnetic charging, and comes in 58mm, 75mm and 93mm cages for cassettes up to 32T, 42T and 52T.

Which Cage Should You Choose?
Pick the cage by your largest cog: 58mm up to 32T, 75mm up to 42T, 93mm up to 52T. Most modern 1x MTB builds with a 50T or 52T cog need the 93mm cage. See the EDS compatibility guide.
Battery and Charging
The OX 2.0 uses the same 800mAh 7.4V battery as GeX. It charges through a magnetic connector with no open port, and the app shows the live battery level. More in our battery life guide.
App Setup and Fine-Tuning
Wake the derailleur by briefly attaching the charger, open the WHEELTOP app, tap Start using and pair. Then set your cassette speed, run the initial calibration and fine-tune each gear. The app also switches between Standard and Racing mode.
