Caution! With this design, a pothole will force one wheel "back" so you make a sharp turn, right into a tree, or right out in front of a truck! Just as when braking harder on one wheel, the trike will turn! Obviously, with strong damping, the danger is less severe, but it is also harder to change direction, when you want... But that "severe-turn-danger" is almost non-existing, with "normal trike steering". I love the idea with side-tilting wheels, and side tilting trike, very much. This made me think: I do not know, if the following ideas has been tested by any builder, but if not, they might inspire a builder. It seems the "normal trikes" all have the "pin" mounted, so the upper end is closets to the boom, and the fixing between the "pin" and the wheel, has the same (but opposite) angle, which makes the wheel vertical (or leaning the top a bit inwards) when steering straight. This means, that when the pin is vertical, when seen from the side, the lower part of the wheel will "tilt inwards", no matter if the wheel is turned right or left... And that is NOT what we want, regarding "sideways-torsion" on the wheels in turns... However, this will ALSO make the wheel move a bit down, when turning... Which means, the weight of the rider, will try to turn the wheels so they steer straight, so the steering is "self-stabilizing", by the weight of the rider... And perhaps this is far more important, for safety, than the solution I suggest next: The "wheel torsion" problem is. If turning left, most pressure is placed on the right wheel, so the lower part of the right wheel SHOULD be tilted outwards, to give a smaller "sideway press", (torsion) to the spokes and the hub, because the pressure is directed more directly towards the hub of the wheel. While that matters less, on the left wheel, as it press weaker onto the ground. So it is better that both tilt the lower part out, when we make a turn!. Which means the "pin" should not point its top IN, but OUT... (But this would make steering the opposite of "self-stabilising" !!! So when turning a but, the trike would TRY to turn even sharper!!!) BUT if the "pin" was placed, so it is vertical, seen from the front, but the top is further back than the bottom end, seen from the side, and the fixing between pin and the wheel, makes the wheel vertical, when steering straight, then, when the right wheel is turned left, the lower part is further OUT than the top part, AS WE WANT, but when the right well is turned right, the lower part is further IN than the top part, AS WE WANT. This solution tilts both wheels, to give less sideways torsion on BOTH... But it will not make the trike TILT, the way we want... In fact, it will tilt the trike a bit the opposite way!!! However it WILL make the trike more stable in fast turns, as the bottom of the outer wheel, moves further from the "mass-mid-point". The QUESTION is: Can we combine the normal "inwards tilted pin" wich stabilises the straight steering, with the "rear tilted pin", so the wheels tilts as we want, while the steering is still stable ??? IF SO, we could combine it with the next idea: Instead of a cross beam, welded onto the boom, it could be hinged. so the ends can NOT move back or forwards, but CAN be moved up and down. Controlled by two tie-rods, connected to the "indirect sterring system"... (So, this is obviosuly not possible with "direct steering".) Obviously, either the cross-beam could be hinged to the boom, or the hinges could be on the cross-beam halfway out to the wheel, of which the latter would probably be best, with less "front-rear-load" on the hinge. Implementing both the "backwards-and-inwards-leaning pin" and the "tilting cross beam", we get the best from "both worlds"... If I imagined this correct, the trike would react, so if we leaned a bit left, without holding the handles, it would steer a bit left... Meaning, it will be important to "balance" the trike, by sitting "straight in the seat", and NOT have a heavy bag on only one side... However both the "wheel tilt" and the "trike tilt", would need to be a compromise, which sadly only works perfect, when riding with ONE certain speed... If riding faster, both wheel-tilt and trike-tilt, ought to be larger...

Where's this at now? Website doesn't exist anymore. This project looks great and people want to know how they can get their hands on this

Genius!!!! So simple!

Is the indirect steering that all trike manufacturers provide considered the AR3 ?

Intriguing. I disagree about the leverage of the handles on the standard trike. It appears it would not be the vertical distance between the handle and the kingpin, but the length of the radius about which each handle rotates, which is a horizontal moment.

Both the kazebike and kazibike domains appear to be dead.

This whole interview is meaningless, David shut down his shop shortly after posting this...did he really ship bikes all over the world??? How many bikes did he really make???

Been riding recumbent trikes for 20+ yrs (ICE trikes) and would be very interested in having an AR3. Any plans of marketing them? and if so "What price?" £££/$$$

How about indirect steering dynamics

Buh bye. That’s a POS direct steering effort.

Hello Is AR3 still made? Kaze bikes still exist? Is a pitty that the trike is not available anymore. It looks like a very smart tilting design. The geometry is like the trucks of a skate board.

Quisiera ver.en castellano por favor

Brilliant. Is it possible to add suspicion to this type of steering?

Not only this, when in a turn on other trikes, you could possibly flip the trike, to help stop flipping you have to shift your weight to the side in the turn. Not on a tilting trike, your center of gravity automatically shifts into the turn, no need to shift your weight...

And after 40 years still didn't sell design to any current recumbent trike company and two years later no longer available for sell...wedsite is gone...i would have bought one...

I just want to know how to adjust for different people lengths...is it adjustable?!? Sram just came out with thier eagle transmission...does and can you have an UDH set up in the rear so we can easily add the eagle cassette and t type derailer???

What happened to your company??? I think you are a genius engineer... And, you kept it simple, 'stupid'...as the saying goes.... I think you should sell your design to one of the (american) recumbent trike companies...

So you disappeared, ill buy now, why lean into turns when you can tilt...why is there no manufacturers of tilt streering??? Should have sold patent or design....

I will buy your bike, where to go???

Kazibikes is no longer available, where are you????

Damnit I am always a day late, I what this trike but now company is not to be found... But if it is still alive please add an UDH on the back, pleases....

AR3 WHERE ARE YOU?!? I don't understand why current recumbent trike companies have not done this yet!!!

thanks

That’s the best system l have seen by far 👍👍👍❤

Thanks for sharing. Awesome engineering. I’ve seen Bowhead and Stein Trikes try to tackle this, but the front suspension makes it too complex and probably too heavy as well. A rear suspension and maybe just larger tires would help with dampening for this design. The steering dampener really makes this design stand out for me. I’ve seen so many of the other designs not address the issue of over tilting. However, for the sake of design, aesthetics and parts availability, I would like to see a traditional round tube boom in front of the steering dampener. I can’t wait to see the evolution of your design in the future. Good luck!

Where would buy the chains for those bikes? They're extra long or do you just add two normal chains together? Good video

Hello David. are the AR-3 still available? if not, i'd lvoe to have some images on the steering mechanics; i'd like to make one. greetings

The wheels move fore and aft when steering. That means a force like a bump on one wheel will induce steering forces. Is that under control with this mechanism? Otherwise nicely executed idea!

Your website expired. You should claim it before it gets taken...

7:49 Caption says "craft test" instead of "crash test".

Tadpoles are tricycles, not bicycles.

You’re a genius. This idea is brilliant 👏👏👏👏

In my oppinoon there is a big misunderstanding about leaning in corners. On a two-wheeled vehicle you don't turn the steering to lean into the corner. And also on a trike the steering-angle on fast corners is so little, that this won't let you lean resonable. You may lean only in slow corners, when you don't need it. (this may be the reason why no driving-scenes of this invention are shown ...) The design of the steering may add a more stable ride on straits. That's probably the only advantage.

I don't understand how you can show us over minutes many people talking about riding this trikes but not 1 second showing the trike in action ...

Very good idea. It's a quite easy way to get the trike tilting. With not to many parts and natural self centering. There sure may be many advantages on fast roads. But the steering angle seems to be quite little. Can you show us this bike in action? Fast and narrow corners?

no footage of how they rode it?

Huge thumbs up! Suggestion: if the wheel on the inside of the bend was not behind but in front of the outside wheel of the bend like skiing, it would be probably better. In short, it would be a mix between the skateboard truck (reverse), the ski and the car at the directionnal level. Nice job again, MR. (from france)

Your trike is perfect. Bravo (from france)

It looks like you could easily reduce the track/width to below 67.5 cm, in which case you’d have a market in Singapore soon, even with bodywork. Trikes are currently banned on public roads but apparently they will soon allow ones under 70cm wide. And there’s already a trike shop here.
