Video: 30 Bikes Hucked to Flat in Slow Motion

 Yes

 Merry Christmas, here's some huck to flats

 @mtb-thetown: *hucks to flat... or actually, since this compilation has multiple locations, "hucks to flats"?

 

 

 your only lonely if you don't have a bike.

 And watching that 50 to 01 edit was sick

 Dont now what makes you sad about this. I See pure beauty

 I have always wondered about this. It seems like the coiled bikes dont do this as much. Is it the linkage or is it the air spring?

 Disgusting telling us details about your bowel movements ! Sounds like too much eggnog!!

 @ilovedust: eat more fiber, drink more water.

 @kobold: The tires also act as an undamped spring so I think it affects suspensions as the tire flattens on landing then get back to its original shape quite quick, I wonder if dealing with this could drastically improve handling or just marginally.
I once imagined there may be a "tire damper", either with some sort of vavle opposite to the inflating valve, and leading to some sort of air can with a bladder and that would inflate on landing and release its air back to the tire more slowly, but that would be a lot of unsprung weight.
Another way would be to put the bladder inside the downtube, but then you need a hose going from the tire to the bladder, which requires a 360° valve (like 4x4 that can inflate tire pressure while rolling) which would need special hubs.

 I think the point were the sus seems to stick is the sag / pedal platform. It would be interesting to compare these videos with their respective anti-squat graphs or something. Just a thought, not an engineer.

 @kobold: I think it is both. The air seals stiction should amplify any discontinuity in the linkage.

 @Scartissue148: what would really be great would be Huck to flat with telemetry! For maximum geekery, strain gauges in the cranks and handlebars. Then some dubious engineering of graphs and stuff. Or go full on Avatar and have motion capture dots on the bike to see where all the bending actually occurs

 I think what you're referring to is generally caused by tyre compression and rebound.

 @Will-narayan: Cush core inserts and lower tire pressures

 @Will-narayan: Interesting idea. I wonder if even temporarily reducing air in the tire via this external bladder would lead to a low more flats. I'm imagining a scenario where you hit multiple sharp edge rocks in quick succession and the first one reduces the in-tire air pressure by filling up the bladder.

 Are you talking about huck to flat or squat to shat?

 @Will-narayan: I think you're kind of describing an attempt at replacing (or supplementing) the weird squishy behaviour of the tyre with an engineered spring damper system. I think what you're after is something that is stiff under fast compressions to stop rim impacts, then refills fast. You could do this by having a carcass that is resistant to expanding under pressure and has a much lower volume, by filling the space inside. You could then have a secondary volume (a rigid tube) with a small entry hole or sprung valve to resist filling the inner tube under fast compressions, but being soft under slower movement, then a one way valve to allow the air rapidly back into the outer chamber. In reality, I suspect the foam in a cushcore does a pretty similar job to that lot, in a far lighter and less complex manner, as well as protecting the rim

 @kobold: I feel like they run the air springs lower than normal as some blow through the travel instantly

 Lunch space maker

 @mountainsofsussex: Not sure inserts would do the trick as they're already equipped with in the video, but I was talking about the "bounce" of the tire rather than the squish actually.

On the full-sussers, the tire flattens on impact, quickly returns to its original shape, then flattens again, it's air moving inside the tire, edforming the tire which possibly disturbs the suspensions a bit.

On the hardtail there isn't this effect at the rear, the tire flattens and slowly goes back to its original shape.

Your idea makes sense I guess, though I was thinking the other way : Let the tire deform on impact (and the insert do its job), but have a tire that goes back to original shape slowly to avoid that bounce.
You'd need to "trap" the air that is displaced on impact out of the tire for a short time (be it a secondary tube or whatever that is not in th same air volume as the tire and that can expand) before letting in back in the tire.

But maybe it's noticable only because it's in slow-mo and doesn't really affects handling for real.

But maybe you idea is better. Some kind og D3O strip that would harden on fasst impact, and be soft on regular riding. But the balance would be tough to find I think.

 @ilovedust : wait...is this comment about the video quality, or some anatomical function???

 @Will-narayan: Or just, you know, ride your f*cking bike. Jezus, if you want to feel nothing go ride a road bike, or use Swift.

 @Will-narayan: rather a lot

 as I sit post Christmas at work or trying not to work i noticed as the front end goes through its travel and the head angle changes or a combination of the rear end squatting it is almost as if at slow speeds the front wheel stops or wants to go backwards, it is probably not an issue at speed, but makes the huck look like it is being done with the front brake on.

 @WhateverBikes: Then I assume you ride a fully rigid bike ?
It's not about feeling nothing, it's about having the suspension behave smoothly, without a tire bounce interfering.
But s said, maybe it's visible in slow-mo but not really a matter for real.

 @Will-narayan: Yes, I do.
I still ride the Raleigh Dyna-Tech Torus Ti that I bought new in 1994, and I love it.
It came with a rigid fork (the totally awesome or hideous - depending on who you ask - U.G.L.I. fork) originally, but I trashed that in 1998. I replaced it with a simple RockShox fork, 'cause that's what you did back then, and I've never liked it. I went back to a rigid fork 3 years ago, when I rebuilt my bike in to a gravel bike of sorts. Let's call it a monstercross bike. Best thing I ever did, I'm enjoying my bike more now than ever before. It's fast (well, it feels fast, and that's all that matters), agile, and fun, and you really need to be on top of your riding technique. I love that.

 @WhateverBikes: Ugly indeed :p Though in a way it has some personality.
I gotta say, I was talking about this for racing, but personally I don't care about feeling the ground, I mean it's cool if it's smooth. I may be weird but what I like in riding a bike is being in movement, moving/exercising, feeling the elements, seeing landscapes, the occasional animal, bird, I'd probably do some bikepacking if I had enough confidence in life and myself to do so, duh...
I don't really care about speed or technique. I have a Honzo ESD but now I mostly ride my Meta Power, with 170mm of squish, 29x2.6" tires and I also got a set of wheels with 29x2.4" slick tires and it's just cool.
Though I wouldn't mind a fully rigid bike but a fatbike, with a gearbox, as a resilient bike for when the system collapses :p .

 Make it 70kg, clipped in, hands like a Lego minifig around the bars for an authentic crash landing

 @sjma: for some reason this reminds me of that commercial where they taped the dudes hands to the handlebars and throttle wfo for a jump.

 You mean, a different dummy than the one they suckered into jumping bikes onto flat?

 Really close to seat rub on that one.

 Look at the riders knees and legs during the compression.

 Tires are part of the suspension also however, they're undamped. Keep a close eye on the tires and you'll notice the two phases of suspension compression.

 I think it's a frequency issue. Just answer to be seem as a smart one, but i really don't understand

 Not much?

 could be hard tyres

 The Patrol and Wildcat both seem to need some more rebound damping

 agree, except of that poor boxxer, looks like it flexed more then bottom of the line RS 35 Silver on that Stumpy

 Scratch that

 Hopefully not play doh.

 A bike ramp.
