I know a couple of folks who have Cruzbikes

Basically, more commercial version (about $3000 us )
Steering takes a while to get used to. I 've heard the learning curve described as "short, but steep". You use your hips to pivot instead of you knees.
You can ride no handed with no problems.
I've thought about getting one one of their conversion kits and mating it with a y-frame bike to see if I can get the riding thing down
