I started this idea in my kennel trailer thread:
http://endless-sphere.com/forums/viewtopic.php?p=306751#p306751
but it needs one of it's own for me to develop it separately.
The idea is that this Freecycle.org find:
will become a single-wheel pusher trailer, that I can clamp on the seattube/post of any of my regular bikes.
It won't fit DayGlo Avenger or CrazyBike2, due to the rack on DGA and the seat design on CB2, but The Velcro Eclipse will work (although it already has a front hub right now) and so will the Schwinn Sierra or other regular DF bikes. Depending on how I make the rear end it may also fit the semi recumbent cargo bike being worked out in another thread.
The trailer folds right now for storage and locks with this
if I take care in designing any drive systems for it it should continue to do so.
If I take the handlebars and seat off of this trailer:

I can bolt a platform across their mounting points, and put something down the side of that to keep anything from touching the rear wheel and any drivetrain, and use these as soft cargo bags:
They were originally big computer-tower carrying cases from CompUSA's old training classes stuff; I considered using them on the bolt-together semi recumbent cargo bike originally and there are pics in that thread:

It is likely that at first, to test how safe it is to use as a pusher, that I will use a hubmotor wheel in place of the existing rear wheel and pedals. Since the current freewheel is rusty:
that's a quick way to check out the idea. It was rusted so much that it would not freewheel. A squirt of WD40 mixed with gearbox oil fixed that, though it's still very loud and probably needs scrubbing out. Chain is rusty but works at the links.
Also, there is a neat little flagpole holder already welded onto the rightside dropout area, with a couple feet of stub of the old pole still in it. I'll probably fix that up with a flag.
It is a 24" wheel, and I may have to cut the brake-crossmember and the "kickstand plate" (neither of which have holes in them to bolt those things to, but are present nevertheless) to allow tire clearance.
My only question is whether I should lace up a 24" wheel with the 1000W GM/9C hybrid, or just use the FUsin or 9C hub in their existing 26" wheel.
After I verify that it will safely work as a pusher using a hub, I'll see about converting it to use a chain-driven wheel from a motor like a treadmill motor or something, just to see if it'll work, and to get back into making my crazy drivetrains that I have not been doing for nearly a year now.
