Do I Need Suspension? I Don't Know, But I Added It Anyway.

In this episode, Mr Super Matt shows us that he misses motorcycles through interpretive engineering

Best automotive channel for nerds on YouTube!
“Engineers make the world a better place by making it easier to be lazy” Great quote (engineer here) but I know a lot of technicians and mechanics that would say the opposite!

I love how much information your videos convey so quickly with some humor sprinkled in. A list content!

[Anfidurl]

"How hard could it be...?"
Oh god he said the words.

We need to petition Youtube to bring back the 5-star ratings instead of "all we have is this thumbs up thing", for videos just like this.
That was the most entertaining synopsis of suspension theory packed into six hundred seconds.

Thumbs up for 5-star!
Thumbs down for thumbs up only!

what a suspenseful episode, quite the shocking amount of work to get it to work, but it all smoothed out

[braedon.builds]

Thank you for not talking about your junk or the greatest new fishing app you’ve “found” and “actually play!!”. Makes me cringe everytime I see it. Love the clean crisp content. Short and sweet and everything you need.

9:34 you have just given the most compelling reason ever to become a patreon ... those pesky public pubic shavers on youtube are becoming a plague!

One of the scariest phrases ever: "I could <do thing that makes sense>, but I have a better idea"

Thanks for putting in the clearance for the laser cut parts, and err... not advertising grooming gear!

Love the video but the thing I love most is that your explanation of suspension movement at 2:58 used an image of what looks like a classic mini which actually has a system that is not dissimilar to that of a bikes swinging arm but with only one side supported and rubber cones in place of springs. A fascinating design that was created to fit in a tiny little car.

The tabs are my biggest improvement in engineering ever, it is so much easier to get someone to weld it up as it is just like a puzzel. It fits a lot of ways like a puzzle but is only right one way.

@1:48 What you don't have is not just independent suspension, it's roll articulation. A conventional beam axle suspension is not independent, but it does articulate in roll.
I'm surprised that you didn't mention that the same thing (swingarm, no roll articulation despite two wheels on the axle) is still found on quads, and they all used to be that way.

[brianb-p]

The steering linkage, with the U-joint to isolate the steering from suspension movement, is clever. But tying the two side together at both the handlebar and the axle seems more "over-constrained" than "redundant".

Brilliant as ever Matt. I for one welcome our Crab People Overlords…

[drewdane]

Motorcycle engine, motorcycle suspension, motorcycle steering... You're building a 4-wheeled motorcycle, aren't you?

[_Hanover_]

So glad you are taking its along for the ride of building this!

All hail the algorithm!

And crabpeople!

I want to let the algorithm (ALL HAIL) know that I am sad when Matt doesn't add a post-credits bit. S A D

[SamuelVella]

Awesome! That about the same clearance I used for my locating tabs when I worked in sheet metal fabrication. I love laser cutters.

Good luck with the streamliner! not an easy thing to go over 200mph.

You can get semi-independent wheel motion if you tune the torsional flex of the swing arms. Makes the design a lot trickier though as they're a spring and you can't just throw steel at the problem. Afik, it's a good idea to have some suspension so you can damp tire bounce. Oh and chain can twist 10-20 degrees without issue, I think sprint cars often do this. I'd recommend a plastic chain guide on both sprockets to grantee that the chain engages properly. (dirt bikes have a chain guide at the rear sprocket to do this)
