I think that video will need to add more VFX transitions and filters, not enough cowbell either.
I’d really like to see their steering mechanism, but it’s all hidden on their website.

Definitely needs more cowbell

Looks to me like simply a special CNC pivot part that goes into the center of the front wheel bearings.
My only question is if they have any trail for their caster.
much less messy diagram
Well yeah, they would have to. If the steering axis passes through the axle, the only way to get trail is to rake out the steering axis.

actually, I’ve been coming around to the idea that the most general name would be “inline boards”. I think it’s descriptive and sounds pretty clean

That sounds closer to describing those boards with 2 MTB wheels and no steering from way back in the day before reliability was invented.
Are you talking about dirt surfers?
I don’t think “inline” has anything to do with MTB specifically, it just means it’s a single track machine
How about “things like skateboards that aren’t skateboards”
Then we can include the onewheel.

How would that help someone make one of the boards seen above?
I mean I would like to see a onewheel with added features of a single Freebord castor up front, and could have rollers on the back if you don’t want dragging. Nice that the vesc controllers are quite compact so you can find room to mount something like that on the front easily.
Then you can take the middle hub motor off and have one of these more plain boards.
I feel like the onewheel is mechanically in the same family as the EUCs. Rigid single wheel and electronic balancing.
Inline boards (ripsticks, SpeepDord™, dirt surfrers, mine, etc) all have a related layout and related steering geometry for front wheel articulation.

I can agree to that, stick it in the “balance wheel” category along with the og segway

Fuck the Onewheel.
If you want to include funwheels, which includes the Future Motion brand funwheel called the Onewheel, then that’s another thing.

I was adhering to the “production boards” part of the topic
I didn’t see that part, am and confused where you see it.
But either way, there are production funwheels, no matter how much the Future Motion lawyers hate it, that don’t say Onewheel on them
Maybe I didn’t look hard enuf but still I haven’t seen any dual drive of these boards.
I kindda interested in building one using scooter hub motors.
Just wondering how powering both front and rear wheels affect the overall stability of the board?

Not sure if that’s ever been done before. The added gyroscopic effect in the front wheel should make the steering feel steadier than would otherwise happen.
If you build it with a 4 bar steering linkage instead of a simple head tube it may create a significant righting moment under acceleration that will inhibit steering the front wheel, since the steering axis moves laterally with the 4 bar setup.

The Surfscooty is an electric in-line board. The frame is a Z shape built in unidireccional carbon T700 sandwich, It Flex and twist with the foot pressure, then turns, like a surf and snowboard, just carve.
The front wheel is a caster steering, helps for small radius turns, the steering system is in the middle of the rim hole and has a rubber bushing for self-aligning and prevent a crazy mover when starts to ride.
This is the Surfscooty V-5 for Flat Track race, the tires are not ones that mount, comes with SunF A021 tyres.
