We had prototype #3 at the show and briefly attached it to my V20 to give some Cruzbike folks a feel for riding it. We did not display it publicly at our booth, but those that came out to the grassy knoll where our tent was set up got to examine it, including a bunch of young engineering students who may use it for a project. It has a very unique design, with a 70 cm wheel track width and 30 cm trailing tilt arms that allow over 45 degrees of tilt. I've been riding it around my neighborhood in NC and it feels smooth. Making good progress on the lock-out feature. We will do an email update with a video of the Ttrike in action in a few weeks. This design has potential to accomplish all the goals we wanted, but needs a lot of refining before it's ready for production. Still a year out at the earliest.
