Interesting!

I found some older versions of this tech (which I did not know about) demonstrated in these videos, though this appears to use the front wheel to achieve the effect, rather than the rear wheel. This is probably disconcerting for the rider, as it means that the handlebars are decoupled from the front wheel:

I am also reminded of the (now defunct?) effort by Lit Motors to create an enclosed two-wheel self-balancing vehicle. They did it entirely with gyros, though, whereas Honda seems to be taking the approach of altering the center of gravity in real-time with adjustments to frame geometry.

Here's a video about the Lit Motors effort:

My question is Why? Why would this be needed? If you can't keep a bike upright, then get a sidecar set up or trike. Sounds like a solution to a problem that does not exist.

In the Lit Motors case, the answer is obvious: because you can't put your foot down in a fully enclosed vehicle.

For Honda, I think it's more of a technology exploration than an actual intent to produce a product.

This is one of the coolest vehicles I have ever seen.

There is a Swiss company, called Peraves that offered the Monotracer, an enclosed cabin motorcycle with front suspension and drive train from a BMW K100.

Today the company seems to be located in the Czech republic and offers a new version with an electrical drive train.
Here is their website: https://www.peravescz.com/

I saw someone with a Tucano Thermoscud on an MP3, camped out at a stoplight with both feet up the other day. Made me wonder about how an MP3 works; I had presumed it only locked the wheels when parked.

No, MP3 (and Yamaha Tricity 300) have front suspension lock with handlebar control. It only works under 10km / h and with the throttle closed, you have to be good at coordinating the drive between idle speed and throttle. Habit.

What Attila said. You can lock the MP3 suspension with a control on the handlebars, very similar to a motorcycle turn switch. Twisting the throttle will automatically unlock it, but this can result in the bike going in some unexpected vectors if it was locked at less than a perfect 90° angle. Much better to manually unlock the suspension and then twist the throttle.

And, of course, it bears repeating: the MP3 is not self-balancing. It just has the ability to lock the front suspension.

I think you have quite a lot of experience with a 2 wheels at the front scooter, with the Tricity more specifically.

How do you judge the advantage? Does it bring what the constructors claim? The better stability, the better braking and the lower risk of skidding.

I have ridden the MP3 250 and 500 extensively. They greatly lower the risk of front-wheel skid, especially on less-than-ideal road surface (wet, sand, etc). This comes at a cost of weight, however.

You can push an MP3 in the corners with a degree of confidence not found on two-wheel vehicles. That's not to say it's immune from danger, just that it mitigates that danger by a large margin.

Recently noticed this one from a Chinese company.

Quite nice EV specs as such, but they've thrown in self-balancing features too.
Although I'm a bit curious about them showing such features only as animations, where as there are many vids available of this bike just riding around....

Well, seriously speaking, self-balancing is fully doable with modern signal hanling and processing speeds.I'd say any university student group studying e.g control engineering or such could do one as their senior year's project work.

We did an electric, programmable, self-balancing spinning top device utilizing gyroscopic effect when I was a student... and that's already awhile ago Much more simple, yes, but many of the control theory principles are mathematically the same, even if the measurements and actuators were not.

What is more interesting question is fault tolerance and durability in real environment... I'll guess that's one of the main reasons we see only/mostly 'hoover board' applications today.
