On the iX5B's stock 46T spur that is about 15T for 1800–2300 Kv. Tight tracks gear down, open tracks gear up. For a starting pinion matched to your motor, use the So Dialed Pinion Recommender with the iX5B selected.
The iX5B has an internal ratio of 3.308:1. Final drive ratio = spur ÷ pinion × 3.308. With the stock 46T spur, a 12T pinion gives an FDR of 12.68 and a 19T gives 8.01.
