A few weeks back on my commute home I spied one up ahead getting on the freeway & making it's way to the HOV lane before I could so I ended up behind it.

Man are those things WIDE.

Agree about the Can Am Spyder comparison. Rode a friend's Spyder and hated it. This looks a lot closer to a car but a LOT more fun and could have a much wider audience.

 

Anyone know the price?

That looks like a blast! The ability to lean solves the inherent instability of a 3 wheel design. Remember the 3 wheel ATC? The government had to ban them because they were so dangerous.

The Spyder is a scary machine. I was asked to ride it and design an autocross course for a focus group study. This diagram from the PersuMobility site tells the story of why I dislike the Spyder and really found it dangerous:

The Spyder behaves in the same manner as the car on the left. Centripetal force acts not only on the vehicle (car or Spyder) but also on the driver/rider. While riding the Spyder, I felt like it was trying to buck me in the corners...and it was. I had to slide my body way to the inside of the saddle to stay on...like riding a sidecar outfit with TONS of grip.

 

Also, the steering effort on the test mule was very high, a problem that was fixed on production models. In order to give the rider enough leverage to turn the machine, the bars had to be a mile wide. I could not hold on to both ends of the bars and move my body so as not to get thrown from the machine. Scary. Obviously, BRP added power steering, but has not figured out how to defy the laws of nature.

 

Dynamically, the Persu looks like a real puzzle. Looking at the same diagram, the front half is tilting, the diagram suggests some centrifugal motion, but the rear would still roll, subject to centripetal force...like the car. In other words, there should be two arrows over the Persu, one over the cabin showing lean and the other over the rear showing roll (in the opposite direction). Interesting dynamics.

 

I wonder about the grip up front. The engine is mounted over the rear wheels and there is tons of rubber out back...good for braking bias but not good for weight distribution. The front tire, meanwhile, has a tiny contact patch. Looks like it could understeer very easily. It's not clear, however, if the Carver technology also adds some steering articulation or just permits the cabin to tilt.

 

Of course, this is all guesswork based on some simple pictures. But looking this all over has helped to make me 45 minutes older. But I am still younger than Mihalka. :wave: Paul!!!

PS: I am not a physicist...but I did sleep in a Holiday Inn Express last night.

Yeah, i saw these a while back. They are cool. I rode a can am spyder and while its a cool novelty to impress people around town, it didnt do alot for me in terms of fun factor. It more scared the crap out of me in turns as it made me feel like I was going to fly off. It does get alot of looks. The carver looks like an awesome sensation. I dont know as if it will ever be worth that price but since they arent offered here in the US then I guess I dont need to worry about it.
