I would typically plan for 60 km between swaps, which includes a healthy error margin (I owned a Gogoro 2+ when I lived in Taiwan a year ago). Gogoro advertises 110 km but that is at 25 kph which is unrealistically slow.
60 km actually goes quite far in Taiwan, which isn’t a very big place compared to eg the United States. Gogoro has an extensive network and you only range limited in rural areas like the east coast or the central mountains.
