If this is a duplicate, I apologize.
I LOVE THIS BIKE.
It needs some development, but the combination of low center of gravity and relaxed riding position are awesome.
For heavy but not-too-bulky items, this would be exactly the ticket.
Improvements I see would be a more direct drive train, lightweight construction, and better thought out rear and front racks/baskets.
I also think it would be reasonably easy to add a full fairing for all-weather riding.
Discuss!

Nice ! Plenty of room for batteries if going electric !

An interesting concept, but it has an awful lot of room for improvement.

In principle, with the low cargo C of G and load area within a short wheelbase I can see the general design working as a Tradesman's bike, but not as a daily general purpose load hauler or delivery bike. For example; a carpenter and his basic hand tools as in the video, a plumber with a bundle of copper pipe, assorted fittings and plumbing tools, an electrician with mobile PAT testing equipment, etc, and even a gardener transporting a rotary lawn mover. I can also see it having possibilities as a Mr Bike, mobile bicycle repair workshop bike (there are a few of these popping up here in the UK now), and even a traffic control/ parking enforcement officer using it to put out temporary road cones while out looking to ticket illegally parked cars. It may even work as a bicycle paramedics steed... ... ... I have ridden on of the fully loaded paramedic's bikes here in Norwich; they haul 45-50kg of emergency life saving gear everyday.

The pedal heel arc strike area encroaches well into the cargo area reducing its volume; unlike a flat bed and open top box style cargo bikes there is a cargo ceiling limit on this style of frame. Drive train layout is crying out loudly for improvement: I actually know how to do this and the components to use, but for the time being I will keep this to myself: I am currently prototyping a particular drive train. I dislike open derailleurs on a bike with 20 inch wheels, I think they and the chain are too vulnerable being so close to the ground and I for one think an IGH would be the much better option here. A better design and layout of the framework is definately needed and incorporating multi axis tube bends would reduce the weight, reduce the number of welds, making the frame more rigid and strengthen it.

Gareth, you make a good point: This style of bike would probably handle decent with a heavy load, like tools or books, but unloaded would probably get squirrelly pretty quick.
I'd love to experiment with it, though.
For a low budget handyman service, I think it would be perfect.
