I know they have plenty of indoor power and if you can't take the bike in with you just charge the battery assuming you can remove it from the bike, I think there are many businesses that wouldn't mind giving patrons a little charge up. In the spirit of e-mobility the idea of creating a website listing possible ebike charging locations is a good idea. I don't ride beyond my bikes range and frankly I'm spoiled by Tesla's Supercharging network so lack the patience for slow charging.
