The cars were advertised as reliably getting 80 miles (130 km) between battery recharging, although in one test a Detroit Electric ran 211.3 miles (340.1 km) on a single charge. Top speed was only about 20 mph (32 km/h), but this was considered adequate for driving within city or town limits at the time.
From Wikipedia
Considering what roads were like at the time, and how far most people were from other things, 80 miles round-trip is plenty.
Heck, that’s plenty nowadays for a lot of people.
