I'm not Rando but I can tell you the battery range mostly depends on the rider's power input and on too many factors to give the definitive answer. Yet, for anybody concerned with the Vado range, the UI-600 Specialized battery (including a separately ordered cover) is available for less than US$1000, it fits all Vados and Comos, and solves the range issue for good
P.S. To illustrate the issue, I can only tell you my brother rode for 75 miles using 450 Wh of battery but it is something not doable for most of us mortals...
For sure. I rode 33.5 miles on my Como 4.0 last week using only about 25% of the battery. But....I had dialed down assist to 15% (was riding with a friend on an analog bike) with minimal climbing. Only 171Wh were used.
