This will be a smaller lighter version of the SB Cruiser:
https://endless-sphere.com/forums/viewtopic.php?f=2&t=67833
built as a grocery-getter/etc for my sibling Raine. It doesn't have to carry the kinds of loads SB Cruiser does, and probably wouldn't be used on the roads at the 20MPH I ride at, or go on the length of trips I sometimes need.
This is the preliminary design:
26" wheels on front and rear (for better ride quality, and to simplify spare tires/tubes, etc).
One of the wheels will be the Fusin geared hub that I'd had on Delta Tripper. The other will probably be the IGH-hubbed wheel I'd also had on there, though I'd never gotten around to making the chain drive to the rear wheel on DT, as the front wheel chain drive worked well enough for my purposes at the time.
Then a regular front wheel for the front wheel.
Frame to be built from the scrap 1" square tubing I still have, though the "downtube" and main full-length tube will probably be built from something stronger/larger. Perhaps multiple parallel tubes, perhaps 2" round pipe.
Steering will be tie-rod type, like CrazyBike2, rather than tiller like SB Cruiser, because of Raine's physical limitations.
Seat will be a suspended mesh or similar, to give a better ride without a thick hot padded seat.
Because of the taller wheels, the cargo area is slung below the axles, like Yogi's trailer.
The frames for the wheels might be done like the trailer, or might be something like a regular rear-triangle, or some hybrid. I'm still working that out in my head, for best strength to material amount/weight, and practicality of shape for structures needed to connect everything.
Not in the picture yet, but it will also have a pedal-chain drive like the SB Cruiser, but also like that it probably won't get used (neither of us can really do the pedaling thing much anymore). Probably it will go thru a 3-speed IGH just so that derailers and such don't have to be kept aligned and working.
Not shown is the sun-cover for midday shade; not sure how I can make one for more than that without blocking view, though.
Design will evolve over the next few days or so as I work stuff out with Raine for sizing and dimensions and usability, reach, etc.
All of the above stuff may be used as experimental tests on doing the same kind of modifications to the SB Cruiser, once I know they'll work.
