The bigger wheel would be better for bumps, but I think I'd like two.
The rear suspension swing-arm is a good idea, too.
Standard, the spring would be too stiff, but a weak spring could replace it.
Just had a thought, I've got a few dampers with built-in springs from some heavy duty printers that I bought brand new as surplus a few years ago. They have about 3-4" of travel, but are fairly stiff. If I set up a cantilever arm, adjustable to double or even triple the travel for varying loads, I'd be in the ballpark. The damping seems right, low on extension, tighter on compression.
These were very expensive printers/scanners, intended for the post office for printing stamps and receipts etc, but the Govt changed their mind and sold them as surplus. (They were $1600 ea to the govt, but they sold them for $40 ea. 1200 printers. Just under $2,000,000 down the drain.)
No wonder our economy is in trouble in Oz.
The main body of the printer pivoted upwards for service, with the shocks to hold it up and then to slow the downward travel afterwards to avoid damage. They'd be almost perfect. Thanks for getting my brain thinking in the right direction. (These printers had half a dozen top-notch stepper motors in each, along with timing belts etc, that's why I really bought them.) I've been wondering for years what to do with the shocks.
