Gravity Racing Downhill from Colombia's HIGHEST Road | Our Guy In Colombia

[@who_cares__]

Love how Guy instantly bonds with a bunch of fellow law-defying mechanics over a deadly sport. Maybe he's Colombian after all

[@samuelgarrod8327]

Hahaa, Guy is the epitome of law-obeyers. 😂

[@toxictrace6775]

I second that. It must be natural in this environment otherwise they'll smell the bullishit a mile away. I don't think most of this kids knew Guy's background, probably didn't care until He walk the walk that until the end as It shows they embraced him. The whole video is really kool, transcending madness with an evenly humbleness. Just watching it was really nice, no wonder Guy was loving it and even better that He had overall a great experience in Locombia and as a Colombian really pleases me.

[@toxictrace6775]

​​@@samuelgarrod8327Jajaja! Hard to comtemplate that.

[@andrespineda5190]

​@@toxictrace6775¿quién es Guy?

[@iankirwan8156]

Guy is such a down to earth person, very likeable even when in a different continent, with a language barrier. All time favourite sports/TV personality

[@PuffinPass]

Man what a throwback for me, glad the algorithm decided to put this in front of me. I learned about GPV racing back in the 80s and made my first one out of an old Murray BMX frame. Walked it up to the top of the longest downhill I knew of and proceeded to go faster than I ever had before, no helmet, no pads and rim brakes. I have been thinking about building another out of a cruiser size frame for the last couple years with disc brakes on it and seeing this makes me want to do it even more.

[@cristianr3712]

Guy thanks for coming to Colombia! First time I saw your documentary years ago I would have never guessed you'll be here. Thank You!

[@joshuabender2366]

Hell yeah!!! Finally, I'm not alone with gravity biking.... I've got a motorcycle fairing on mine... I live in northern California, and there's tons of of great descending here... I'd love to get down there and ride with those guys! Stay safe and solid amigos!

[@Vate13]

Im here in Spain feeling the same, this would be a nice sport, gravity bike races. We love you legend 💪

[@sebastianquivar6414]

Se me aguaron los ojitos al final, qué chimba los gravitosos 💓

[@Vate13]

Ojalá fuera popular en todo el mundo este deporte

[@peedee4065]

More weight does not make a bike descend faster in virtue of it being heavier. It's a matter of giving the bike more momentum that that is less affected by road vibration and wind resistance. At a certain point there are diminishing gains.

[@pehpoh5086]

the potential in theses dudes .. 👍

[@Marthyboy88]

This has got to be one of the coolest videos on the entirety of youtube

[@nismo2070]

The shot at 5:55 is breathtaking. Well done!

[@nigelcarren]

Agreed, getting high the best way! 👍🏆

[@gkky_]

@@nigelcarrenAs a colombian, I can assure you that those guys 1000% smoked a couple joints while sitting on that ledge.

[@toxictrace6775]

​@@gkky_ Jajaja! I second that. I believe the cut that one out!.

[@oakleygt]

What a bloke to send to Colombia to represent our country. 👊🏻

[@schillieschild7633]

Who cares this a reupload! Be glad that they not completly removed it.😢 Al the series Guy makes are top notch, just because he's a normal person not a fancy celeb. Also big credits to all of his team that go with him offcourse beautifull shots always.👍

[@arcaneminded]

"normal person"

[@bigbird2451]

I'm 2m tall, so I built mine out of a Bontrager 24" BMX frame with Rock Shox DHO forks with an upside down BMX bar and a front disk brake. I run pegs on the rear axle for my feet and made knee platforms out of thick steel angle iron that hang and pivot from the bottom bracket.

[@ellisberry8747]

Dude that sounds awesome

[@stump68]

Guy Martin repping Clutch!! Epic !!

[@yamagrn]

Me and my friends were doing this back in 1987. It was popular in the BMX scene.

[@Mudsuitable]

That looks like fun, my friends and I used to lay down on skate boards and do the same just didn't have a hill that epic!!

[@mesagoat]

yup, me in Pennsylvania in 1985, saw this in BMX+ magazine of sum Cali boys, so... I found a 700c road frame, flipped it upside down, added 24" wheel on rear, added 20" fork wit a 16" drum brake wheel on front, added backwards bars & footpegs, proceeded to hit 59+ mph (wit' friends tryna keep up in my car), just before dark, in the rain, on our local mountain! a total rush y'all! 🎉

[@charlesxavier8017]

Guy Martin, also wearing a Clutch shirt. EPIC

[@staticcorvette5998]

0:40 he got way too excited about that bit 😂

[@BOGASUP]

We did this in the 80s with BMX bikes flipped over, slicks and pegs and dropped bars. Full drag knee stuff, was insane. Surprissed I am still alive.

[@Vate13]

That sound fun

[@Jimmyhickey90]

Mannn i was really hoping someone would make a video about these guys, its a culture/sport youll find in every town in the andean mountains of Colombia. It was pretty trippy when i saw if for the first time

[@revzombie]

Different, unusual and unique niche future bike sport ( hopefully), would be great to see red bull rampage level with custom built bikes, would love to watch that...

[@RagdollRacingInc]

Now that's proper 👌

[@federicoaldi5663]

Fantastico 😍

[@mikadavies660]

It's dangerous and many die.... Guy is in...👍👍👍

[@frankiek2269]

That looked pretty slow to me. The danger of dying must be on a different downhill. I think they took Guy to the bunny slope because they didn’t want to be responsible for Guy getting hurt ‘on their watch’. Lol

[@AlphariusBlackPill]

W 😮w!! 🤔all that fun for the value of a round trip 👍

[@DaveSlaz]

Why the re-upload?

[@mortenhuvastenseth6943]

Every time make me smile

Fill the frame with lead shot. Buckshot from shot gun shells or lead fishing line weights.

[@siverbeach1502]

I saw this when i lived in medellin for a couple of years. Nobody would believe me when i came back to the States. These kids were crazy af gondown these hills.

[@danielcoy9147]

CLUTCH🤘🏼

[@andrelintelligent6269]

Allo Guy Martin

[@gur262]

Race the GCN guys on descent on road. They found bigger tyres better already. I suspect typical roadbikes just unnecessarily suck in many ways. A bit longer and slacker wouldn't make em slower on flat but faster downhill, but that doesn't work with the uci. Xc mtb geometry is probably better. Afterall motorcycles have longer slacker geo too. ... I don't know math i just know my bicycle at 70kmh is terrifying

[@Vate13]

😂😂

[@204jeffmike]

Cool Clutch T-shirt

[@paullord196]

I like how Guy is wearing a Clutch shirt.That's a local band where I'm from in Maryland.A friend of mine went to highschool with those guys.

re-upload ????

[@PiDsPagePrototypes]

Looks like.

[@keithfisk5641]

Adding more weight to the bike does not increase the acceleration. The vertical acceleration from gravity is approximately constant at about 9.8 metres per second per second. Force = Mass x Acceleration or written another way Force / Mass = Acceleration. If mass is doubled then the force from gravity is doubled and the acceleration remains the same. To maximse speed the best bet is to be as light as possible so that bearing friction and tyre rolling resistance are minimised.

[@PiDsPagePrototypes]

Not, quite,... more mass equals more grip, and from that, higher cornering speeds become possible before sliding,.... to a point. Eventually, speed overcomes grip, and you're pulling stones out of skin.

[@keithfisk5641]

@@PiDsPagePrototypes More weight means higher centrifugal force in a corner so more grip is needed from the tyres to resist. No doubt there is a sweet spot somewhere but adding weight always brings challenges.

[@PiDsPagePrototypes]

@@keithfisk5641 It's all down low compared to where the rider is.

[@joemcmanus3585]

@@PiDsPagePrototypes not at all. Why even say that when there are actual real life examples of this not being true? F1 cars are made to be as light as possible to reduce MASS. Downforce is generated in a plane perpendicular to the center of mass of the car so it only presses the car down, and does not increase the centrifugal force that wants to fling the car off the race track and into the wall.

[@PiDsPagePrototypes]

@@joemcmanus3585 Do F1 cars have engines, yes. Do Gravity Bikes Have Engines, NO. Do F1 cars use an engine to generate airspeed to make downforce, yes. Do Gravity bikes have an engine to generate airspeed to create downforce,.... No. Do you now realise why your statment was not thought out? Probably still not. Also, F1 cars mass is set by the rules, not the engineers.

[@django2467]

We do the same thing here in Barbados but way more sketch

I watched the show , very good guy you need to take the drag bike to Officialy gassed you tube channel drag races!!!

[@_ElNacionalista]

quien iba imaginar que Guy Martin estaría en Colombia haciendo un reportaje a los de Gravity, aun que el como consejo y de forma esencial debió darles clase como usar la protección adecuada a uno ñeros que aun no aprende que una cosa es el deporte y otra la irresponsabilidad.

[@Crackrocksteady]

The cops closed the roads for the races 😂😂😂

[@realcucus]

Estas neas si sabrán con quien estuvieron parchando? es decir el nivel y la historia de Guy Martin ?

[@OmegaphysX]

: Most lads I started with are now dead, That's not enough to scare Guy, he's raced the Isle of Man 0:44

[@tHaH4x0r]

Love you guy, but you might have to retake physics class 😂 Mass doesn't make you go faster. Sure, the force acting on the object is greater, but so is the mass that needs to be moved. Its larger momentum needs a higher force to accelerate it. The effect of a proportional increase in the force accelerating the object is cancelled out by a proportional increase in the required force to move the mass. See also the experiments Galileo did in Pisa, showing that two similar shaped masses of different weight do indeed fall at the same rate. Another way (which in my opinion makes more sense) is by looking at energy. Going from a certain height downwards, you convert gravitational energy into kinectic energy, minus some losses. Suppose we perfectly convert all that energy of a given height, we can equate the two to figure out the velocity: mgh = 0.5mv^2 Rewriting this we can get v=sqrt(2gh). As you can see, the mass component cancels out, only gravity and height difference are left. If anything, I suspect a heavier bike will go slower! Namely because of higher forces on the bearings and other points of friction, causing slightly higher losses.

[@deemo5245]

Been a while since I did physics, but F=MA is not applicable to speed here, A pea and a bowling ball both fall at 9.8 m/s2 and hit the ground at the same time. So it’s about friction and drag, I think?

[@gur262]

Hmmm. I noticed me 100+kg roll down faster than others when things went downhill.

[@gur262]

Maybe different with friction n ground contact involved?

So all the badly made, clunky, too heavy kids bikes actually have an activity where they can shine. Seems the more overbuilt and heavy the bike the better it would be for this.
