I mean even in European cities most deliveries are on motorbikes or, as you point out, increasingly on ebikes. My girlfriend routinely orders Uber Eats and Glovo and I've never ever seen one delivered by car.

According to zipline[1] it is still better than motorcycles at least. Considering we are talking about 100km, I would not consider a bicycle an option for such small packages.

That said for me delivering a package by bicycle+ train + bycycle is an option but it will always be more expensive unless you can stand long delivery times.

The vast vast majority of couriers in NYC are on e-bikes or mopeds.
