Other than sleep, there's nothing much I LIKE to do while waiting for a charge.
I can tell you what I DID do when riding a 60-mile range E-moto from SF to LA. I ate tacos. I got a massage. I watched a movie. I napped in the grass beside the bike at 2 a.m. I hung out in a Jamba juice. I ate a steak dinner. I hung out in a bar drinking non-alcoholic beer.
