Aye Up,
Well propped up shindig.
An interesting concept/prototype. Good for the beach/flat terrain. I've been using bog standard wheeled tool bags for the same purpose for years but not with quite the same load capacity - but also not the weight that the frame/table of the Freewheel either!
It is also an area that has periodically raised its head in the military world with framed rucksacks that have an axle tube and large off-road wheels attached.
I've even come across a civvy
attempt - perhaps tracks are the answer!
And one of many alternatives -
No Bishop, I thought about it too - I reckon a couple of sets of rollers attached to the frame around the large hollow wheel perhaps.
An all woman company? Why no mirror attachment and curling-tongs rest then? Only joking ladies.
Next phase - an electric motor!
