Title: Tilting 3-wheeler concept
Post by RaleighGuy on 11/17/16 at 03:56:45

I just found this article yesterday and at first, the pictures seemed strange but the more I read, the more sense it made. Keep all three wheels flat on the ground but shift the center of gravity by pushing the rider to the inside of each curve.

Piaggio has been making scooters like this for a while.

Did your father forget to take off your training wheels ?

Those are for people afraid of two wheels !

Pussimafied tricycles

Think I'm using JOGs dictionary

In defense of the Piaggio, I see it far different from training wheels or the usual trike. You're still leaning into the corners. The one person that I knew that had one was a very avid rider and bought it just to see what it was like. I think he ended up giving it to his mom when he was done with it.

The upside is that it locks the suspension when you come to a stop. No need to put your feet down so it would be very nice for someone that has low mobility or maybe a missing limb. You still get the 2 wheel riding experience with the stability of a trike at low / no speed.

Well I'm not looking for one yet,but that carver scares the hell out of me ,two large tires pushing that skinny donut in the front? Hit some gravel or loose sand or a fresh rain in a curve and see how long you can keep that baby on the road! If I'm on three wheels I want two up front for traction and braking !

I'd like to see what that is like.

I have built 4 or more trailers in my day from scratch, 2 were for pulling behind a motorcycle and both worked wonderfully.

I had in my head and somewhat on paper the notion of a motorcycle with a sidecar where the sidecar leaned with the cycle. Then, I found out that someone had already done it. I didn't get it built, but it was fascinating. I had ridden some bikes with rigid sidecars and I didn't like the feel.

I'd thought about looking into adding a sidecar to the Harley I'd had years ago but between the extremely high cost of a quality product and having to deal with the greatly reduced flexibility of riding alone, I quickly dismissed the idea.

I would probably never consider buying a Piaggio but I'd love to rent one for a day just to see how it handles on some of my back country roads near my 'hood. ::)

I don't see this NTV concept as really workable ,they're showing a lean angle of 52 degrees ,unless the base platform is highly weighted what's keeping the rider from hitting the road? These people are putting out minimal info ,fishing for investors ,in a project I think is doomed to fail.If this design is workable,show me a prototype,not a silly drawing! Their drawing shows the center of gravity (the symbol -a circle with four quadrants),outside the two front wheels,which would make the inner front wheel a fulcrum ,were as the two wheeler next to it has the weight directly over the wheels no matter what the lean angle.the Piaggio mp3 works because they run motorcycle tires that lean in such a way as to equally stay in contact with the road ,thus the center of gravity stays in direct line with the bike .

I test rode an MP3 Piaggio a few years ago. Couldn't get it up very fast in town, but it handled nicely. Very stable in the corners.
A couple of "issues":

1. The front end is very complicated and HEAVY. I definitely felt that weight. It wouldn't take long to get used to it.

2. Yes, it will lock the front suspension when you stop. Yes, it will lock it with it leaning!!! Soooo.. you better take the lock off and straighten up before you take off! ::)
