Yes, - you have to have good strong spokes tying the wheel together. I've never had any problems with my tricycles despite carrying heavy loads, but then on the other hand I'm not trying to corner fast either.
Velocars and other interesting vehicles.

Yup.
Bikes lean, cars and trikes don't. Wheels have to be much stronger to take the side load. Or it's taco time. Which leads to hospital time. And that's really expensive.
You been ridin' Anne? Feeling better?

Yes I've been getting out and about a bit Mike and I'm feeling much better than I was. Thanks for asking
I can't speak Spanish for toffee, but these video clips are just plain delightful

Hello Annie,
Great motorised cabin-qaudricycle, very rare type of body. Could be good for two persons, seating in tandem, just to have bigger doors?
No mater of language, anyway more talk when information. Second video is better.
Now, two videos about cute DIY open quadricycles. Videos are a little too long without a lot of information, but there are some interesting details. It seems to me that the guy is the same, but second vehicle is more sophisticated: suspension, steering, revers gear, body... The first quadricycle is simple and have center-pivot swivel steering and suspension! It goes quite steady over not so flat surface. I am not sure in such suspension/steering system, especially over bumps and holes. Probably quite impossible with front brakes? Maybe to put feet on front axle as rude system of amortization?
Here are links:

Enjoy!

Mike,
Then, solution is to design and make tilting (leaning) 3-wheeler (complicated) or 4-wheeler (even more compolicated)? There are mayn of such solutions, but I should replace one problem with many more, even I like tilting vehicles, HPV or motorised.

[FONT=Comic Sans MS, cursive]I found those ball-bearings in Croatia (not far away from Serbia and Belgrade), but in Serbia too! There is parallel numeration 61904 zz or 6904 zz... Prices isn't too high. Just to check O.D. of TOMOS moped hubs...[/FONT]

However, I had in Belgrade two 18" wheels from my old motorcycle JAWA 350, but they are much heavier, not so good for HPV velocar with small engine/motor. Could be good for 3-wheeler with engine - just to find one more wheel! There is some time to think and check all that, until March next year when we shall go to Belgrade... Maybe I still could find two 16" wheels of my brother's old motorcycle MZ, if they are still in basement of his old home. (he passed away 5 years ago)...

The design of a leaner is actually remarkably simple, regardless of the number of wheels - for example any parallel dual a-arm assembly (arms of equal length) has the potential for leaning without adversely effecting camber, the difference is little more then an added pivot point;
My (non-leaning) T3 during during construction;
Here's one of many leaners, this one designed to have both suspension & leaning ability;
Steintrikes Wild Wave (prototype);
For many more examples here's a link list, there's more - these are just the two-in-front taddys;
http://tiltingvehicles.blogspot.com/search/label/Pedal Powered - 2 wheels front
...however - there's an issue rarely spoken of yet plagues all leaner designs & that's variable speed stability. I spent a bit of time & effort on the subject as my T3 was initially supposed to be a leaner, yet the more I researched the more I found examples of other leaners attempted, some only on paper, many built & tested & some, like the Steintrikes 'Wild Wave' pictured above, about to hit the market...
..and then silence: https://www.youtube.com/watch?v=PqUe3J1vJV4 (don't bother, the vids are now "private")
It could be Steintrikes removed all their public video of the 'Wild Wave' leaner right after it received such acclaim simply because it's about to be retailed, but this follows the pattern of leaners appearing & disappearing over the years, every other design having the same problem reported, if spoken of at all. It's sometimes only hinted at with "it takes some getting used to" or "it's unusual, there's a learning curve" but it seems these simpler (non-computer controlled) lean designs perform amazingly well at one speed, but at other speeds they become increasingly unstable as it's difficult at best to lean the precise amount needed for a particular speed.
So, thwarted by a complex & vague "problem" I abandoned the leaner aspect for my project as I had other design complications to attend to - I don't mean to discourage, rather I hope what little I've learned will aid you in your quest
Thank you for the links Zoran
There is another link for the centre pivot steer quad......
https://www.youtube.com/watch?v=-b5Ue0xAA_c&index=2&list=UUgcRVnKT9hzx-F0MoS88YvQ
Judging by the video it seems quite capable of handling rough going.

Hello Annie,
Thank you on new video: it is much better then two I sent, and with intersting details of chassis, suspension and steering - and qaud was driven over more interesting road!
Photos are great, too. Did you scanned them from video or found somewhere else? I enjoy a lot. I could do that under some complicated process, so use that rarelly.
P.S.: Attached is photo of some nice and delicate chassis for HPV quadricycle... (velocar or velomobile?)

Thank you on personal observations and gathered information about tilting (leaning) HP vehicles! I was interested in such vehicles for some 10 years, when found the first detailed information on Internet (guy named MAX?). Many years before that, I had thoughts about building one simple, in spite that I didn't know for them at all (before computers and internet)... With internet, I gathered a lot of information, thoughts of designers, photos, sketches, diagrams – videos! Good that you sent to me that link, I had it saved somewhere but lost some years ago.[/FONT]
[FONT=Comic Sans MS, cursive]My humble opinion is that titling vehicle could be designed using all that gathered knowledge, but still have some issues if pedal-powered. If we wouldn't use any “electronic brain” then we must use our own “brain” to coordinate tilting angle and steering angle, with condition on a road: speed and curve diameter (height of C.G., too). Fixed relation between steering and tilting couldn't give good results at all speeds. Steering is in some way similar to steering of an air-plane: we need both hands and legs for proper combination, with our brain and some practice. Only with high seating (as on ordinary bicycle) we could use balancing for tilting, but I wouldn't depend on my sense for balance. (and prefer velocars)The same, I couldn't know to design and construct some complicated mechanism that could do that all for me with only hand commands (need legs for pedaling). Beside, some people say that pedaling and moving of our body have influence on tilting, and maybe steering – without our will?[/FONT]
[FONT=Comic Sans MS, cursive]Now, I re-consider abounded idea of tilting system, this time for my present quadricycle (if decide to reconstruct it). But, I think that I do not have proper resources for that: knowledge and experience, tools, time (in front of me) and money! No possibility and will for too much experimenting with unknown result.[/FONT]
[FONT=Comic Sans MS, cursive]But (again one “but”) - who knows?[/FONT]
[FONT=Comic Sans MS, cursive]P.S.: Attached are phtos on themes "Who needs tilting velocar for transport of masses?"

P.P.S.: BaW, you are master of machinist and mechanical arts, but I am not!
Attached is a pair of phtos with tilting vehicles of great (for me) designer Neumann Neander. Motorised tilting vehicles, could be simpler for governing?
(we could have free legs for tilting commands)

Dont shoot me. I'm just the messeger.
This is a Chevy design for a sort of all weather segway to be sold in China.
Good luck keeping the wind screen from fogging.
Looks very Power-Rangers-esque.

Ludwig,
This one is better for me!
Probably - more expensive, too - being USA made! Hopefully, it has Chinese Diesel engine and be something cheaper the expected?

Jus' an update/correction;
This was just posted BTW: http://youtu.be/IbTSJD5Rp4I
...so I've no idea what their reasons may be for pullin' the original vids, perhaps they've sorted the variable speed stability issue, tho it'd be nice to see the leanin' in action again lol
