How big is the market for 300 kilograms of photocopiers? I'm pretty sure an average few streets of web shopping, a bag here, a coat there, a few mugs two houses over and two boxes of LEGO on the other side of the block, stuff like that. This sounds easily doable by cargo bike, assuming the infrastructure is sufficiently geared towards bikes of course.
@DLSchichtl@Iron_Lynx of course there are things that can't be delivered in bicycles and of course this only make sense with enough density.
But density is a goal of urbanism.
The places in the world that currently have success doing bicycle deliveries right now allow night time or off peak van/truck deliveries.
Most deliveries are small packages, especially the deliveries that are time sensitive and so are ideal for cargo bike delivery.
The 2-3 photocopier deliveries a week are done with a van at night.
Let me rephrase it: how big is the market of domestic/household users for 300 kgs of photocopiers? Of course commercial shipments are a class on their own, while household cargo is generally so reliant on a handful of small packages every week or so that you can do that by bakfiets.
