Fueled by burritos and solar power.
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. …

I started this site as a sort of repository for links to information about this project with the idea that I would have a place to occasionally post things that didn't fit elsewhere. The FAQ is freshly updated but most of the content I've been creating is where the eyeballs are: deep technical dives on …
Justin from Grin Technologies came down for Maker Faire back in May and shot a video for their YouTube channel.

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