ATB speed record?

flyjump - 7-3-2011 at 08:34 AM

Is there one? does anybody know if there is a speed record for mountain boards or where I can find the info for this? I don't think i've ever seen anything about it

carltb - 7-3-2011 at 11:42 AM

http://forum.kitecrowd.com/kite-landboarding/board-speeds-11...

ive not read through this thread but there might be some info there.

flyjump - 7-3-2011 at 12:51 PM

looks like it is somewhere around 48mph

shehatesmyhobbies - 7-3-2011 at 01:38 PM

A bar for you to achieve Adam! Reach high brother!

flyjump - 7-3-2011 at 01:40 PM

I think i would have to setup a different board for speed challenges. my board is too flexible and i have skate style trucks for quick turns. I think i would need a heavier board so that I wouldn't get speed wobbles. I'm curious to see how fast i'll be able to go. i'll see if i can borrow a gps at NABX as see what i can do

Looks like that was a dirtsurfer. I am not scoffing at those speeds on a board, But...

Is that a fair comparison?? Half the number of wheels and larger too.

flyjump - 7-3-2011 at 02:53 PM

he was also using a kitewing, so i dunno if you have to take that into consideration too. i'm not looking at gunning after the record or anything, but i was wondering where the ball park was for atb. On the other forum it looked as if some of the other guys were saying that it doesnt count since it wasnt with an actual kite. who knows

WELDNGOD - 7-3-2011 at 03:04 PM

Guess I might have to step up and see what MY TRAMPA can do! 17 ply long 35 degree w/VerTigo trucks setup firm... Speed is why I had it built that way.And I got racekites and several small fast foils.

ripsessionkites - 7-3-2011 at 03:51 PM

100km/h

just kidding, i have no clue but was hoping to make you think there was so you have something to aim for.

*I typed it this low because I know you're probably using your iPhone*

flyjump - 7-3-2011 at 04:13 PM

hahaha ricardo! not only am i using my iphone i'm using a first generation iphone lol. not that speed is my thing but i'm anxious to see how fast i can go on the playa. what day are you heading out there? seems like time is going slower the last few days.

ripsessionkites - 7-3-2011 at 04:34 PM

arrival is 26th

hitting the playa on the 27th by noon

carltb - 7-3-2011 at 04:35 PM

a dirtsurfer and kitewing aint a landboard and kite !!!!!!!!!!!!!!

zero gee - 7-3-2011 at 04:39 PM

This is what I ride. It's a directional board. I learned to gybe on this board before I tried gybing on the water. I don't know what my top speed on it is. It is fast. But I don't have room anywhere here to really let her go and only had it on grass fields.

It's stiff and heavy. The front wheels are slightly toed-in and canted for more bite and stablity. With a long wheelbase and widetrack and it's 12.5" wheels with tie-rod steering (no trucks), it can hold a big kite well and tracks nice upwind with very little side slip and no speed wobble. Steadiest ride at speed of any ATB I have tried. :yes:

indigo_wolf - 7-3-2011 at 05:52 PM

FWIW: Shortly after its production Glen Butcher clocked 42.8 mph on the Quardolution.

His current WindWarrior profile lists his top speed as 49.2 mph. The Quadrolution is still listed as his weapon of choice for speed runs.

Inverted trucks tend to make the Quadrolution inherently stable compared to conventional boards and the larger, thinner wheels reduces rolling resistance.

The caveats are that the Quadrolution requires groomed fields or hard pack due to the thin tires and lower ground clearance.

ATB,
Sam

dylanj423 - 7-3-2011 at 06:13 PM

there is a video somewhere of eli going 40 mph on his board... GI flight light i beieve... the video angle is the fliers point of view, looking at the bar in front of him with the gps...

legit im sure...

i have hit 29.1mph.... winds in mid teens.... im sure you can go super fast on the playa...

also, for what its worth, i dont think weight has much to do with wobbles, i believe anti-wobble comes from high stiffness of the deck/truck combo...

Houston AirHead - 7-3-2011 at 06:49 PM

wow, ive done about 32mph. i cant imagine going faster lol

702dirtsurfer - 7-3-2011 at 10:58 PM

I've hit 50.9 mph on my 16" dirtsurfer with a 5.5, still a record I believe regardless of the board or sail. Getting my hands on a 3.8 paired with a 20" dirtsurfer, 60 is the next benchmark! I'll have a dirtsurfer and kitewing to try out at NABX, and I'm always game to compare GPS's

WELDNGOD - 8-3-2011 at 06:03 AM

dirtsurfer is deffo NOT in the catagory! 16" vs.8" wheels not fair comparison not to mention it is a 2 wheeled vehicle not 4 like an ATB.It has front forks not trucks! A Kitewing is deffo NOT in the category either, it is NOT a kite on lines, also NOT a fair comparison. What Adam is refering to is a FOUR wheeled standard ATB/ MOUNTAINBOARD and a KITE on LINES ,FLYING in the air.
A dirtsurfer is a hybrid of a bicycle and a skateboard. Therefore it's records only stand against other dirtsurfers not ATBs.

Bladerunner - 8-3-2011 at 06:42 AM

I am stuck in a similar way with my Coyotes .
I can cruise comfortably at 35mph but hitting 39 everything changes. I can go faster but seem restricted by the wheels / vibration ?

Is there any kind of technical / safety chart rating top speed for different sized wheels and loads ?

702dirtsurfer - 8-3-2011 at 10:31 AM

I've always thought of it like ATV's. A dirtbike (dirtsurfer) is an All Terrain Vehicle,as is a quad (mtb). ATV and ATB are general categories. As for the kitewing. Since the body is the mast and it still takes a bit of maneuvering it it, flying a wing is more closely related to flying a kite off the handles than anything else. But no matter what anyone says,the only thing that matters to me is this...

I littered the playa with my dust screeching across the desert at 50 mph, my arms killing me, "pumping" my kitewing,looking at the gps trying to squeeze every last drop of sweet speed as the threshold of my ability and the playa room finally reaches an end. The gear may be a little different,but the experience is still the same. And under wind power,I'm still the fastest man standing up

See y'all on the playa!

flyjump - 10-3-2011 at 11:39 AM

702dirtsurfer, you are gonna be at NABX!? sweet. i'm glad there will be more dudes on boards out there. there are two other landboarders from PL that are coming out to the playa this year. they are both coming frmo the netherlands though. look forward to riding with you :thumbup:

702dirtsurfer - 10-3-2011 at 01:48 PM

For sure man,maybe I'll even convert you to the dark side haha. Truth be told though I don't have the super big air capabilities y'all kite/mtb ers have, I have speed and upwind strengths, so I usually try to keep up with the faster buggiers. But I could slow down and say hi for a few paces

Pulsar - 10-3-2011 at 04:19 PM

According to this topic on a dutch kitelandboardforum, there's a guy that did 92.1 km/h (57.2 mph). In the same topic the record before that is supposed to be 86.7 km/h (53.9mph).

Also there seems to be someone keeping a (rather large !) list here.

Edit - oh great, looked all over to find the topic, then i see it had already been posted >.>

702dirtsurfer - 10-3-2011 at 04:25 PM

Nice! Thanks for the info. Now I just need to get my hands on that 3.8 :evil::evil:

Oh, this sounds like a challenge! I've not yet proven I'm one of the "faster buggiers" but I have a world class buggy this year, and a desire to find our limits. I really enjoy seeing someone scooting along with some speed and try to chase them down. Maybe we can give it a go in a few weeks. All in good fun of course. Winner gets to smile bigger. :smilegrin:

indigo_wolf - 11-3-2011 at 05:44 AM

Saw the postings in the kitelandboardforum.com and then read up a few posts to this by plummet:

"Well a couple of weeks ago while doing my 24hr sometime during the night session between 1am and 7am my gps tells me I hit 80kph (49.7mph)."

I read that as him riding his landboard for 24 hours. Yikes!!! Plummet's a madman in all the best ways.

ATB,
Sam

702dirtsurfer - 11-3-2011 at 10:54 AM

Beamer,its a deal! And when you move down here we can go chase after the white buffalo

Feyd - 11-3-2011 at 04:53 PM

So let me get this straight. Is the record for a landboard 57.2mph? And did I see GT bicycle sponsorship on that guy's kite?

Looked like he was getting pulled wicked off edge.

Hmmmmm, I find this interesting.

Now you have a challenge Flyjump! :wee:

I'll still be chasing you B'bob! Being almost twice as big as me I think it's only fare you have to fly almost twice the kite size like last years chase!

Can't wait to ride with the dirtsurfers again!

WOOP WOOP :wee:

BeamerBob - 11-3-2011 at 06:43 PM

You know, the riding there is fun, but its the people stuff that means the most to me.

702, I'm afraid to ask what "the white buffalo" is!

BR, I hope its you chasing me this year and me using my "Ken mirror" on my new helmet to keep track of you.

702dirtsurfer - 11-3-2011 at 08:22 PM

Guess you never saw the movie Hot Tub Time Machine hehe. It's something fleeting,unattainable,or something/someone that got away from you. Say a record of sorts lol. Heck even wind is a great white buffalo sometimes

BeamerBob - 11-3-2011 at 09:23 PM

Yes, this wind sport is chock full of the fleeting and unattainable. Chase it we will.

Mine is to be flying and max out what the kite is capable of. Just at the edge of fully powered yet not over the top. I had it last fall on Jekyll Island riding with Angus. 8.6 Reactor II screaming in the wind with 3 tires breaking loose with little gusts. Hitting around 30+ in 10-12 mph winds and the kite seems motionless at my side. But we are far away from talking about atb speed records now. Back to our regularly scheduled program! :wink2:

Feyd - 12-3-2011 at 05:09 AM

I woke up thinking about this.

I think I need to get a board.

WELDNGOD - 12-3-2011 at 08:48 AM

and lots of impact protection! Trust me ,wiping out from a stand up position is brutal!

702dirtsurfer - 12-3-2011 at 09:37 AM

I keep telling myself I really need to get some racing leathers. The playa was unforgiving at 30 standing up (cracked my snowboard helmet)

Feyd - 12-3-2011 at 04:47 PM

Don't worry, I have the armor front covered.

I believe that Bob Childs has the top speed of 50? mph on Doom Wheels. Now these are speeds you want to go off season. NO ? Have you ever thought of fashioning a set of those up ?

I think I would incorperate bindings if I was making a set ?

702dirtsurfer - 12-3-2011 at 08:21 PM

I actually just bought a pair of roller blades from the second hand store today to make some in time for nabx

ikemiester - 22-3-2011 at 10:25 PM

Anything 50+ would be nuts.... Anything over 30 and I start getting the heebie jeebies lol

ikemiester - 22-3-2011 at 10:27 PM

702dirtsurfer - 22-3-2011 at 10:32 PM

Hit 41 the other day and no lie, 40 plus on a dirtsurfer is so smooth, I thought I was doing maybe 30. When I hit 50 all I wanted was more speed, not one speed wobble!

ikemiester - 24-3-2011 at 10:48 PM

That's because it's 2 wheels! Do ever get speed wobbles on a bike? 2 wheeled things gain stability with speed and 3+ wheeled things lose stability with speed. Simple physics.

Gotta help me understand the 3 wheel wobble theory. I've had physics.

zero gee - 24-3-2011 at 11:01 PM

2-wheeled speed wobble...:wee:

WELDNGOD - 25-3-2011 at 04:13 AM

I had that happen to me once,but I did not go down. Some jerk brake checked me on the interstate! I have had speed wobble at 135 mph once on my FJ 600 ,caused by micro tire imbalance. So ,yeah you CAN get the wobbles on 2 wheels.

702dirtsurfer - 25-3-2011 at 05:29 AM

Lol how a dirtsurfer works isn't news to me after 5 years of show & tell, I was just praising it.

And someone really should've told that hit on the bike that he was on two wheels and shouldn't have fallen,simple physics :D

ikemiester - 25-3-2011 at 09:35 AM

and I quote from dirtsurfer, "The Dirtsurfer's unique inline design completely eliminates speed wobbles that are so common in skate truck systems." The reason that motorcycle got speed wobbles was because he turned his front wheel slightly too much. Correct me if I'm wrong, but a dirtsurfers wheels don't "turn" therefore rendering it incapable of a speed wobble

flyjump - 25-3-2011 at 09:38 AM

that guy in the motocycle video didn't simply get speed wobble, i saw that on tv and one of his shocks broke causing the wobble

The front wheel on a dirtsurfer does indeed turn. They are incredibly stable at speed though. The faster you go, the better it runs. I think skate trucks wobble at speed because of the way they pivot on the king pin, the way one wheel moves forward while the other moves back. Something causes the truck to turn, thereby changing the balance of the rider which causes the truck to turn. this goes on till it gets worse when there is a spill or speed is reduced.

I love to debate as much as a pig likes rolling in mud. I'm still curious about how adding a 3rd or more wheels to a vehicle makes it unstable. I haven't found a speed that my 3 wheeled Ivanpah buggy gets unstable yet. Having taught math at a community college and taken physics in college as well, it doesn't seem as simple to me as you make it out. I'm not saying you're wrong, but just want you to explain your reasoning so I understand your viewpoint.

ikemiester - 25-3-2011 at 08:40 PM

I was incorrect earlier about bikes not speed wobbling. I found what seems to be the true answer for why a dirtsurfer won't speed wobble. Here's why

"It should be noted that the Dirtsurfer will never experience a speed wobble normally associated with other bikes or board sports. Because all of the weight is below the hub of the wheel and pulls down on the hub as opposed to pushing down actually changes physics."

JEFFisNOTfunny - 6-4-2011 at 10:51 PM

On my longboard skateboard I've hit 50mph... tracked by a car downhill.

It has to be possible to go faster with bigger wheels and wind propulsion... just probably crazy dangerous.

Honestly... i'd be terrified... I've always felt more in control of my skateboard and water based kiteboard than my mountainboard.

good luck if you are trying.

PS... on a skateboard when downhilling... lean forwards and place much of your weight on your front foot to help eliminate speed wobbles. unfortunately it feels counter intutive for kiting.

flexboardz - 10-4-2011 at 07:06 AM

in the last few months, we have tried to gather information about speed wobble. You can see some of it on Flexboardz.com/Technicz and as it's quite a lot of maths/physics involved, we have summarized part of it in the video below.

basically everything can wobble, the question is how fast it will happen?
Skate/mountainboard trucks with 2 rigid steering axles are very wobble prone even at normal speed...other designs have to go much faster.
It seems that the rear truck is causing a lot of instability (try driving a car backward) that is why longskaters recommend to lean forward on the front truck(to be less perturbed by rear truck vibration)...that is also why Outback and other board w/o rear truck are more stable

flexboardz - 22-4-2011 at 12:41 AM

Recently, we have been contacted by Simpack, specialist of the vibration analysis, and they have proposed to make a vibration study comparing a skateboard and a Flexboardz.
Simpack software use CAD files of the board to simulate the vibration.
Considering SimpacS-P-A-M-L-I-N-K-s expertise of these problem, I am optimistic that they will give a valuable explanation to the wobble problem

indigo_wolf - 22-4-2011 at 03:38 AM

I wish you could get your hands on a Quadrolution to throw into the the analysis mix just because of the inverted truck geometry.

Would make for interesting, albeit geeky, reading.

ATB,
Sam

flexboardz - 23-4-2011 at 01:41 AM

It's still a skate/mtb truck design (with rigid steering axles)...with a lower center of center of gravity and a reduced pivot angle (from what I can see)...so it has probably a similar behavior but at higher speed...

However, your point is right : there are so many different set up that it will be difficult to give a definitive answer to the wobble problem

Congratulations. That's insane!! Have you made contact with popeyethewelder.com ? He might be interested.

Big cojones for going out in the hurricane!!!!!

I found it funny that you woke up early on Monday morning to explain to your board. I couldn't help but be reminded of Fawlty Towers. :D

I have one of these if anyone e wants to try it at WW in the spring.

PHREERIDER - 30-10-2013 at 09:19 AM

just saw this thread up in the rotation. i did some decent runs on FlxBz haize last year ...gps had at 51 or so i posted on extremekites , AUS and got into the thread on kite crowd but lost interest..

hi speeds on haize was pretty effortless compared to regular trucked board. regular ATB over 35 mph just gets super sketchy + the wind u need is pretty hi for hi speed land rides as well.

with haize you can cruise 40-50 no big deal..the issue around doing more for me were 2 things...

first was tire growth(so it seemed)..the soft tires start growing as speed goes up and somewhere around 50-60 its just total sketch for the set up i had ...maybe some heavier belt tires, could have been the float over the wet sand but anyway ...higher speed for the board really is not the problem .

and the second--->flying the kite at 50+mph in 30mph+ wind is what gets your attention, holy crap! JUST ONE pass to leeward at 50+ and only deep consideration for another one.

FLxBz haize (maybe with different tires/rims...like solid rim belted bazookas!) is truly the only ride to attempt this with and just plains nuts or guts to go with it....even fully padded a broken neck is a snap !

caution advised

BEC - 30-10-2013 at 01:52 PM

I think seeing flyguy0101 pass buggies in WW this year while on his landboard that he may have beaten all records....OLD GUYS RULE! from one to another...
:thumbup:

flexboardz - 31-10-2013 at 07:20 AM

Congratulations !
I agree with Phreerider than kite control must be the main issue at such speed...

BeamerBob - 31-10-2013 at 08:04 AM

The things that sometimes go wrong over 50 mph and the things I am able to do to correct them in a buggy, aren't available when your roll center is just above your ankles and you are standing up. Gusts and luffs would probably send you tumbling, and that would be for some considerable distance at more than 50 mph. The trouble is double when you increase from 50-60 mph.

Speak to Popeye, he might be better able to help. As I understand it for kite buggies you need 3 GPS units to confirm a world record, although 2 might be allowed.

Does he have any pictures of the GPS units and witnesses ?
I'm in no doubt from seeing the video that this is fast as he says.

I love this sort of video showing the sand skipping down the beach.

I noticed the wind direction and judging by the graph it looks to me like an almost direct downwind record breaking run! The wind was blowing hard that day!

Wind speed vs rider speed ratio was probably 1/1 or less??
I got my last few PB's in wind speeds nearing rider speed. We need more room or bigger kites!! :Ange09:

I can confirm Dennis's Speed is a world record, I have all the criteria needed, gps logs, video witnesses, photos of two GPS units, (the record was taken from the lowest reading)

His and other landboard PBs are now collated on popeyethewelder.com
