Mine is a 2020 Rad Rover step through. The way I ride is to put the bike in PAS3 most of the time and bump it up to 4&5 on certain hills. My usual ride is 18 miles or less. At the end of 18 miles I have 3 bars still showing. I've been charging the battery after each ride unless it's been just a short errand. Now I'm assuming that if I have 3 bars left after an 18 mile ride that I should be able to easily do another 18 miles. The question is should I do the two rides before charging or continue to charge after each ride or does it really make any difference at all. Thanks.
