What range do I actually need?

Manufacturers quote best-case range under ideal conditions; real range is typically 30-50% lower once rider weight, hills, cold, and higher speeds are factored in. If you commute 8 miles round trip, a scooter advertised at 18-25 miles is a safer bet than one rated exactly at your distance. Long-range models here advertise 40-50 miles for riders who want margin.
