OK, now I’m digging the Strava power stats. Had to get a scale for weight accuracy.
As a commuter I noticed that there’s no weight entry for cargo. I submitted a suggestion, but in the meantime I suppose I’ll create a cache of custom “bikes” – the same bike with different weights reflecting cargo weight for work & shopping trips.
Update: Got a return email from Strava, liked my idea and will present it to the team!
