None, because noone wants to bike 5 miles for 3 bags of groceries.
I do get kitty litter with the car on the occasional trip to Costco because I'm not set on using the bike for every last thing. Just that the eBike makes a lot of things a lot more convenient.
Beer and cat litter alone are the heavy items, and don't fit stable in a bike, especially in bad weather.
Plus 2 weeks of groceries, depending on what you need can really add up.
On a bike? Fah-get-a-bout-it. Guess I'd be biking my ass to the store every day.
Or I could live in the present and drive an actual car.
Clearly GP buys 1 day worth of food if he can bike groceries for a family of four.
I had Uber drivers struggle to bike 1 MEAL for my family.
