During the year there was 1 day I used public transit as biking wasn't possible (snowstorm).
There were 10(ish) days I took my gravel bike instead as it felt safer due to snow / ice.
There were 0 days I used a car instead.
I spent 250eur for bike maintenance (the bike needed replacement parts) and an estimated 20eur for charging it's battery.
E-Bike really is the solution for city transportation.
