I'm pretty new to bikes, but I kind of like this. Looks great for around town cruising or teaching a new rider how to shift and accelerate and brake smoothly without the added pressure of dropping the bike.

Would a modified four wheeler swing arm work to get three wheels in the back?
If so, which one(s) work?

I realize fenders and such would need added to keep it legal, but if a Yamaha blaster swing arm or something could be made to work, that would be pretty cool.

A trike swing arm may work but the work involved and cost could very well be a monster surprise. I would shy away from an idea like that.
As for using a trike as a trainer for a new rider who will be going to a bike later..............bad idea. The idea is to teach a newbie on the kind of vehicle he/she will be using. Trikes and sidecar rigs handle so very differently that they have a whole different set of skills to learn.
Newbies stand a much better chance of learning and living without injury if taught on their eventual choice of machine. A friend of mine who is a lifetime rider and daily rider no matter what the weather bought a sidecar rig and promptly crashed. 15 minutes and he wore the new off his Ural. The handling is that different. He actually wore out the Ural and bought another one. He sometimes disappears for weeks just riding around. No more 2 wheelers in the yard.
