This run is called Hellway. Starts at The Portland Zoo ends at Goosehollow Max Station down hwy 26. The max takes you back up into the hill then an elevator shoots you up to the top its perfect. Rider: Harlan Whitman Motorcycle Driver: Ryan O'Brien and Video: Brandi Kruse
Nice engineering. I get the ground effect and small aero footprint makes it very fast with less wind resistance. That crouch looks to be a bit uncomfortable for a long trek and lack of suspension would concern me but man what a nice ride! It looks like you got upwards of 40+ mph with great handling. Thanks for sharing this with us. Invention moves us all along at a pace that suits the soul...
you only ride it as long as you have a hill. so there are no "long trecks" there are no pedals. this is for bombing hills.
When I were young, we called it riding down a hill.
+manofweed1 Today's concept of riding down a hill is a bit more creative, however. ;)
Yeah, but it's not cool unless you're on all fours and your bike is useless everywhere else.
and unpractical.
Yeah when you were young you were not riding down hill at the speeds, trust me. But nice try to be a smart-ass
"When i we are young"
We useta make these as kids.
Downhill bike we called em.
Get a regular bmx frame, flip frame over, installing forks and handlebars wrong way, weld a post where seat post would come out, seat where cranks were.
Bomb the hills
I will take wind-noise over awful licence-free music any day of the week! Nice work 🏆
Can you imagine the sensation of speed from being that close to the ground?
Ignore the unimaginative commenters, this looks like a great riding experience.
The environment for this shoot is terrible -- all that urban traffic. If you're located in Portland, take a day (preferably sunny) and go to a nearby mountain with a decent paved road to the top and shoot your video there.
It would be cool to have two gravity bikes in the shoot, drafting each other and going head-to-head, etc. Rider skill is a big factor on this platform, I can tell.
The motorcycle leathers/helmet and brakes indicate you take safety seriously.
Crazy. the world needs more like you. KEEP GOING.
Now he just needs to borrow an anti-gravity bike.
+WhiteWolfos Me likey. Smoother Mcstylios.
@MrErock5353 It is a steel shell filled with solid lead. Weighs about 26lbs. The weight helps lower center of gravity and also carries your momentum through slower sections. It's also a play on what gravity folks call "bombing hills". :-) thanks for watching and commenting.
Wow
That’s cool. I love the little 💣
Man this would be the perfect platform for my turbojet bike. I have been running a Kingtech K320G4 on a GT mountain bike. Been 65 mph but I need less drag.
whoever is filming has done a fantastic job. to be moving and bouncing great shot I have seen in a long time
The SV650 that the passenger was on that was recording has a very comfy suspension setup...so there that :P
sv650 IS a nice bike
Camera guy "oh shit! I wasn't recording lets do it again"
Gravity bike dude " damn it connor Now i have to run up hill 7 miles to do it again."
Made my day
You had one job camera dude! One fucking job!
Enderman PE Official-MCPE/Boom Beach/Clash of Clan I was joking...
Jokeception
There's an elevator at the bottom guys
I remember seeing these in BMX Action in 1986. They revolutionized the cycling world, and bicycles without pedals basically became ubiquitous from then on... which is why no one needs to pedal anymore.
Now turn it around and get home ! :P
One way of keeping your nose to the ol' grindstone, looks like fun to me.
We used to make these with old bmx bikes. I think it was even a sport for a while. Scary as hell when your up to speed and so close to the ground.
Is this bycycle motor fitted?
I Think its great that you guys have invented a new way of cycling at high speeds down Steep roads but SIN Cycles you give yourself too much credit for such a simple invention.
invest in a windscreen for that mic. hopefully the shop isn't uphill
OK. Now turn around and go back to home.
I used to ride this hill as part of my morning work commute. I rode a Kona Kikapu Deluxe with Vredenstien Fortezza slicks, Hayes discs, and modified MTB/Road gearing . Used to scare the living daylights out of the TRiMet drivers and commuters when I'd whip past them.... :D Really way too much debris on the shoulder for safe riding. Used to pop alot of tires, LOL.
Oh my, that shopping kart has escaped the parking lot and is now rolling down that hill over there. Gravity Kart!! COOL
This thing with an engine on a racetrack would be great!
I was thinking the same thing what you need to do is just take a motorcycle and crop it into this similar position and holyshit would you have one hell of a motorcycle. I have a fabrication company but I don't know anything about making motorcycles. I always wanted to make a motorcycle in this style. I have all the skill to make it but not the knowledge
It's simply made to downhill fast, and it's obviously faster then a road bike just by looking at the height of it. Plain and simple. Traditional bikes are made to commute, this is made to go fast with as little wind resistance as possible. Just like a trick skateboard deck and a longboard, they're made for different things. Idk why anyone would talk bad about these, and if they do they most likely just can't understand some things are made for different purposes & it's pointless to try and explain to them
It really would be cool if he were actually going fast and taking advantage of the design in the video. I can see the potential for the design but this video is pretty lame.
I don't know how many of these people who have commented are aware of DH mtbing. A sport focused on downhill too, and the bikes can't climb hills either.
That looks so badass
The negative comments are from people, that understand the essence: this is different and a lot of fun. Grrrreat !
yeah, a bicycle without pedals. did I miss anything?
***** When I´m riding downhill on a "normal" bicycle, I will not have to use the pedals to gain speed. The gravity will do that for me :-)
It's brake is your ass that's amazing that's what you're missing
Ivan Blazevic no it won't. On a normal bike you have more wind resistance
Henk Hatzmann ya but you can use a big gear so you go even faster pluss things like an areo bike and good wheels help so ya
Yes, this not just a bike without pedals, this one works on gravity ! As do all things in the known Universe !
All the green eco friendliness of a bicycle with none of that pesky exercise!
Well, except for when you want to go back up the hill and have to either put it on your shoulder, stoop down to roll it along or just ride it one foot at a time in awkward skateboard style!
Buy one today!
Its more meant for speed than getting around -.-
You just take the max back uphill. Max is Portland Transit
Okay, that's awesome. I want one. I want one, and I'll put a motor on it, and make it a Motorlouger.
The wind shear on the mic makes it so much better.
Ita a really cool concept ^_^
errrmm thanks :D
I am guessing he is walking back.
Portland has Rapid Transit called the max which is a Light Rail trains. You can take it from downtown Portland back up the hill in the direction of Beaverton Hillsboro which is West
So Portland, GO Portland!!! Love it!!!
Something from Portland that DOESNT suck. cheers to you buddy. From one of the original Zoo bombers back in the day.
gonna take ages to push it back though
Bus pass
Mission Dan just tie a rope to the motorcycle so it can pull him up there
it's like Street luge but a bicycle
that sound is totally insane man !!! lol
After finished going down a 3 miles down hill, he carried the bike home.
He's going 43mph as he comes off the freeway.
On that straightaway, I would imagine he's flying closer to 50mph.
Funny how people just can't seem to let another person have fun with whatever they're doing. Wouldn't be my bike of choice, but I'm sure there's plenty of speed sensation when you're that low to the ground.
Right?? Like skateboarders hating on EVERY other action sports because it's not skateboarding... That's the point, people! Different sports, different goals and sensations. Life would be pretty boring if everyone did the same fucking thing...
@Christopher White people have a problem with skateboarders because they're so disrespectful and the attitude that goes with it. Also there's a lot of thuggery and arrogance about where they feel entitled to skate. If young skateboarders were way more cool and more respectful they wouldn't get so much hate against them. They bring it on themselves.
nothing new here, we did this with our bmx bikes back around 1987. Just put on axle pegs to rest your ankles on flip the forks the other way around through the frame, maybe some pipe foam over the frame where you rest and blamo! (removed chain, sprockets, crank, pedals etc) Some did upside down handlebars, some axle pegs in front, some just held the fork tubes.... no ER trips ever required for us :)
Dude,TWO-WORDS..............."FOAM-BAFFLE"!!! NEXT video ya make,PUH-LEEEZE have one over your MIC,K??? Thanks!!!
It says it's a GRAVITY bike people. It's self explanatory. It's really no different than a skateboard going down a big hill. It's not meant to be comfortable or practical or safe or anything but FUN and certainly not for everyone.
Fun but also extremely dangerous. One thing I worry about would be the speed wobbles. Anybody who's written a BMX down a steep hill knows what I'm talking about. There's not a lot of traction in such a narrow Tire. But he clearly knows some of the risks as he's wearing the right gear.
3:56 Lol I love that he is speeding on a bike.
I want one of those now. That looks waay too fun.
Passes cop and takes it into hw26 like a savage! I know grown ass adults that don’t like driving thru those curves let alone *SAVAGE BIKE IT*
Great idea. You have designed the first bike that guarantees you will smash your face into everything you crash into.
It looks like you can ride that for a maximum of 10 minutes before your back is destroyed and your arms are on fire.
Re-title this video "The Dork Knight rides the Pratcycle."
It's not designed for long rides, jackass, it's designed for short downhill street racing.
Slow down people! This dude is cool, not like you bums hitting the chair all day.
Cool? No, just a fool.
@@Hithere-ek4qt Yup, that going doing something outdoors is def an idiot. lol
Harlan this is insane.
Finally , someone that can beat takumi on the downhill
at first I thought this was some lame shit.. until about 3mins in when I realized that XGAMES or REDBULL needs to take this, with more hill and more speed and make it a legit sport. There's no way this isn't more entertaining than any of the downhill ski events, and more likelihood of gnarly group crashes. This has lots of potential.
imagine a luge version with this bikes
Yeah this could be a really fucking cool sport. They should develop a class of bike with certain characteristics and measurements and make a league sponsored by Redbull. It would be fun to watch these bikes hit really high speeds maybe even though in too steep turns. They could even be motorized potentially.
right in the blind spot of so many cars.
no speed wobble!!!
left the cars in the dust!
I know it's pretty successful. I think it's the ballast in the bottom that makes the difference
What's with all the negative comments??? There are lots of fun things that you can't go uphill with. this thing is meant for speed. and if you don't appreciate that, then it's too bad,cause apparently 7Million other people do. Go ski!!!
why does it have a tiny bomb inside it?
Think it's a weight for more speed
+CaptainSkelebones Most likely ballast for stability. Probably needed more weight low & forward to keep it from wobbling or handling weird.
+CaptainSkelebones TERRIST BIKE
+Blink Dreach
I think ISIS is behind this project and just wants more people to buy it before detonating all bombs/"stability increasing weights" at once. :P
It's the only explanation that makes sense! ;)
So it's a scooter then.
the first bicycle were scooters
Didn't read the description and realized it was portland! Wahooo!
Oh my, that grandma is taking a stroll down that hill. GRAVITY GRANDMA>
awesome.
Cool, man!
But it looks very uncomfortable riding it.
Driving doggy style, no pedals, no seat, no handlebar - excellent!
we did this 25 years ago as kids. anybody can easily mod a regular bike into something like this, just take of chains and pedals. flip handlebars upside down, lower seat. old banana seat bikes were the favorites, put some freestyle pegs on the rear axles, thats about it. I think you should go with some thin skinny wheels and tires that are high pressure for less roll resistance. Maybe add a small fairing for the rider to tuck behind. Can add more ballast for increased gravity effect / momentum.
My normal bicycle can do that too.....and with the pedals can go uphill as well so mine is better, sorry Mr. Gravity Bike...
The resistence would slow it down and it would reach 25mph tops. As that on hit 40
Awesome Person
idc
Bora Rossi nah
but this is more agile
Bora Rossi No way you could even keep up with normal traffic..let alone HWY speeds. Think before you speak please.
So you've discovered the scooter, good for you
Nice Camera work from the person on the SV650s :)
That looks like a great Giggle :)
That's pretty funny. I was watching this thinking "God that stretch of road looks familiar....". Not too far from what I reside!
every body's a tuff guy HATER on youtube , how come on the streets I don't see so many haters , in the matter of fact , I don't see any haters in real life, it must be a key board thing.
keyboards are mystical artifacts that in the wrong hands they could corrode the masses like water on iron
I openly laugh at people riding silly shit like this.
>"on the streets" lol
@@iunnox666 silly life you have
@ Because I laugh at people doing ridiculous things? Are you slow, and think I go out of my way to do this?
can this go up hill as well?
if you watch the video in reverse he goes up hill.
Simply coasting, like we used to do on skateboards. Time to cook.
Nice videography. Good composition, especially considering the confined position and conditions.
RIP headphone users.
Devon Perry r.i.p gravity bike user
Menina a menina
Devon Perry I we're 1 of them :(
This is one of those videos that could definitely have used music and background sound muted.
Now, if everybody had the sense just to live at the top of the hill we'd never need to use any fuel. WTF is wrong with people?
Fletcher DeMaine They live at the bottom of hills?
Fletcher DeMaine But what about going up the hill back again? I bet it wouldn't be on foot
Lucas Reis ruclips.net/video/vaRSVk0BIbw/видео.html
+Fletcher DeMaine No, they have an elevator in the middle of the hill of course. :P
Haeral Use the kinetic energy of going down your hill, to go back up the hill you work on or something 😉 would be a cool concept but if you were able to make it up the other hill, it would have to be a little smaller to compensate for friction and stuff. So you wouldn't have enough energy to go back up your hill.
Goodness everyone is so full of hate and negativity. This is just a really cool crafted piece of engineering that should just be appreciated. All the ducks saying negative Shit should just deal with what makes them so unhappy in their common, uneventful lives. Cattle...sad sacks. Cool creation. love it with a bionx.
Looks like a fun ride.
is that in oregon?
Preston McElroy thought so
MagpulFan kept thinking "I know that road!?" leaned how to drive out that way some
Yup. Portland Zoo.
Ahmmm, don't see what's the gravitiy-difference between this and the normal bike. Also there are two major flows in this design:
1)The way you push yourself looks extremely uncomfortable.
2)The closer you are to the ground the more difficult is for a car/lorry driver to see you thus the probability of getting ran over is greater.
yes, this design does flow very nicely
1)Lower center of gravity means more responsive turning
2)Lower center of gravity means less wind resistance and more speed
3)He can add a flag if he wants
4)It can be fun to think differently. Always something to learn.
its not for everyday usage its for down hill racing
bike lane duh
These have been around for a while they use them to film down hill long boarding events
I love how I watched this before reading the int section... said "Portland!?" So beautiful.
This Needs to be on outrageous acts of science.
Feels like I'm wearing nothing at all...
Nothing At All...
NOTHING AT ALL...
i like the part where the wind noise made my ears bleed.
+Len Harms my fav part too~! :)
Me too!!😃
Lol goose hallow max stop got to love Portland awesome job guys
Wow! I could dig that bike. Take it to Hawaii and coast down the volcano. Whew!!!
How do you go up the hill so fast?
lol
cuz he was traveling at like 60 fucking mph
how fast is he going?
+jim ritzheimer 43 kph . you can see his speed at the motorcycle speed gauge when the camera man turns around at 3:50 :)
+3bonavista That is what I say, he is on a multi lane highway for a short stretch, speed limit is probably 55
good point, that proves my km readig is fairly right!
@@rbagel55 I drive on this highway regularly. It's 55 through there. Easy.
I love the simple title of this video.
With that suit and helmet I expected so fast riding.
a new revolutionary machine with a top speed on flat roads of.... 0

What is that black ball in the middle of the bike?
acme explosives.
He said ACME explosives though, there is a huge difference.

www.wired.com/2012/12/acme-poster-kickstarter/
it could containt something like a mecanical gyroscope that somehow rotates with the wheels or something, to adjust the weight or something... >.> or alientecnology
The modern version of Flintstones's bike!
Oh my, I was rollerskating and I lost one of the skates and now it's rolling down that hill over there... Gravity Skate!
Would look really funny if he had a Pizza delivery tray on the back!!... Hahahahaha!!!!!!!!!!.......
The comments section would be very different if there were a woman on that bike.
Do you think
So it only works downhill....great....
what, you mean like downhill snow skis, ski jump snow skis, bobsleds, luge, grass skis, snow boards, etc (and some may argue, Fords). It is a purpose designed vehicle made for high speed downhill fun, it is not meant for everyday commuting.
Brad Kowalczyk there are a lot of things that need to be reinvented.....the bicycle isn't one of them....
onth3hous3
This is clearly much faster than and much different from a standard bicycle. The low profile means low air resistance and the lack of gears and chains means low friction wheels. In other words, this thing a specifically designed to go downhill fast. If that doesn't sound like something you'd find fun, don't get one.
Some people are just too dumb/lazy to find out for themselves what something is made for.
A 'Gravity' Bike is just that (the clue's in the name), they're for racing on downhill sections of road, just like Street-luge for example.
No-one's trying to re-invent anything here onth3hous3, it's just another fun thing to do.
John Doc. As an engineering student, I am not "lazy/dumb" to find out anything. Thanks for the assumption though. Also, as an engineering student....I can clearly say that this is a pointless "sport" as you call it because I see it getting very popular (sarcasm if you didn't catch that). There are already bikes designed for speed....why make another?
Craftsmanship on the bike looks great, and must have been built right to be that stable at those speeds. As usual, the comments gave me cauncer. -_____-
Same at malaysian we call it basikal lajak.
I can imagine going uo the hill with thi
s thing...
Dem typos...
Catdog I find it funny that you have a translate button under your comment.
DJBuckCallYo make a spelling mistake and this is what happends...
carry it on your back ...
Arif Rider That is why this is a bad form of transport... You wouldnt drive a car if you had to push it up the hill, right? I do understand that its smaller than a car but if its supposed be used as transport then its kinda useless... But I guess its just a toy to have fun with.
do you think this could be more aerodynamic
Dude literally bombed a hill( highway) that was dope .
That is insane how it can go that fast with just potential energy. Those cars must be doing 50 mph at some points and the bike was gaining on them.
Of course this is in Portland lol
I totally skipped the description lol thanks for pointing that out.
I'm gonna keep this location in mind now :P
Robbie Minor Dream of the nineties is alive in portland.
I live in Portland it's a nice place to live in. :D
As do i.
Robbie Minor Me too, love Portland..
Put a engine on it
The Siskiyou Summit on the California Oregon Border interstate I-5 you can ride anything you want on the freeway for a stretch of about 50 miles..Skies roller skates,bikes,walking,picnics,whatever..this point is the highest point on I-5 and you can coast a long ways on a 2 lane hiway 10 miles maybe farther..do it all the time on a Bicycle..its a big thing around here
Sure be Fun on That!!
+Hugh Jorgen and steepest grade at 6% very fast
+Hugh Jorgen So, Bring that bad boy to one of these Vermont Hills; Killington's Bear Mt. Road, or Q-Burke's Upper Access Road (these were Push Culture/IDF Event hills this last year), Rt-9, towards Willmington, (East, from the Bennington side), or if you want Really Fast, Ascutney Mountain's Park Road (22% grade, mellows to 8-9 % grade; Will kill Fools!, btw.). If VT doesn't scare ya, head over to Mt. Washington Access Road in Lincoln N.H..
Being a Streetluger, i've been there , mostly (all, but Burke; too narrow to make it on my 6 Ft. sled). I'm sure you'd have fun, as long as you have good brakes!
I just heard about a Gravity Bike,But it was a exercise one,but that one looks a lot funner!!
