I ride out of Vancouver early on Sunday morning. The city belongs to groups of tai chi practitioners, surprisingly spry senior joggers, and one solar ebike putting along at 10 km/h (6 mph) because the battery is empty and the sky is overcast. I’m so slow that frail-looking octogenarians on cruiser bikes are passing me. …

Enjoy. https://www.youtube.com/watch?v=7RGBBNctWNA
