When the bicycle became popular in the beginning of the 19th century in southern Germany, England, and France, it was the first machine that championed private transportation. Almost 200 years after the invention of the vélocipède and Drais’ dandy horse, personal mobility is one of the highest imperatives in a globalized world. Today, our streets are filled with fixed-gears, roadsters, rickshas, BMX, and electric bikes.
The Human Power Team has demonstrated just how fast you can go with pure muscle power. The third model of the Dutch team’s high-tech recumbent bicycle, the VeloX 3, reached a speed of 133.78 km/h, setting a new world record for the fastest pedal-powered vehicle.
We visited the Human Power Team in their workshop in Delft, where lead engineer Dennis Berckmoes, although still in the middle of making the final preparations for their next record attempt, walked us through the details of the engineering process, that he and his colleagues from the student team go through every year, designing a new highs-peed prototype.
All of the components of the VeloX4, from the chassis made of extremely hard but super light carbon, to the aerodynamics that are tested in the wind tunnel of a space center, to the special gear system, to the 3D-printed special parts, are individually designed and produced.
“This is Formula 1 for bicycles,” as Dennis put it.

Imagine driving and minding your own business, and then getting passed by a carbon-fibre Lima Bean
I pass people in my carbon-fibre Lima Bean every day. Usually they're in a traffic jam and I'm >50 km/h on the cycle path.
Kevin Johannes HOW DO I BUY ONE?
@@leanmeangreenbeanmachine3347 Mine is from www.intercitybike.nl but before I had one from www.velomobiel.nl. Velomobiel has the wider range, they have extremely comfortable cruisers (for example the QuattroVelo) but also speed machines (Alpha 7). My DF is quite close to the Alpha 7, the company also sells an even faster machine that's less fit for cities, the Milan. Both companies sell all over the world, I was at Intercitybike a couple of weeks ago talking to a customer from Taiwan :-)
Be sure to follow velo-ads and Saukki on RUclips for more info.
Kevin Johannes thank you it’s nearly impossible to find information online
@@leanmeangreenbeanmachine3347 It's not thát hard, you just need to know where to look ;-) Find me through 365cycle.nl (on Instagram, and the website), and I'll get you all the info you need and then some.
"You don't burn fossil fuel, you burn your own fat." There's the slogan. lol

+butlerproman LOL it took me about 15 seconds to think about it. Heh, Good one
calories have to be replaced, and food isn't free.
I'm the rural U.S. I commute 50km at a cruise speed of 125KPH on an interstate highway. It's amazing to see how human power is getting close to this. Can only imagine what it will do in small towns.
Yeah but can you sustain that speed thorough the journey?
I'm sure you could once the tech gets better @@lucasliew4924
I just watched a film about the first 15 years of Airplane engineering. These are the people who make a difference in life. Bravo !
This is some serious bike development. I just noticed it's an eight year old video too. I'd love to see an update on what these teams are doing today.
I'm in my fifties and I've never seen even one velo mobile on the road in real life. Why is that?
@@michaeldesilvio221 I considered buying one used a few years ago. I would think you could vacation around the Netherlands and see a few in or around cities. From what I can gather the cheapest start at $25,000 and require impressive athletic ability and a lunatic level of enthusiasm for human power. So, not a huge market... Naturally flat areas that stay cool/cold year round tend to be the best places to ride fully enclosed.
I would 200% buy this.
@@iamarizonaball2642 Me too, but not for that price.
I bought my velomobile for 7.000€ (new). There are cheaper options, there are more expensive options, but I've never heard of any model starting at more than 12.000€. Also you don't need to be an athlete. I'm no athlete and I ride my velomobile all year. My advice to anyone is: If you ever have the option to do a test ride, do a test ride.
Sooner or later they’ll have a bike powered submarine
Those already exist, one was made back in 2010
That was the first submarine that ever existed...... But u pedaled it with your hands
Exists
2:11 ?
Already did, and long ago, in 1776. Look up Bushnell's Turtle. It was a one man submarine shaped like an egg. It was propelled by a hand crank and it was designed by the American colonists to attack British ships by attaching an explosive charge to the underside of the hull. The Turtle worked but the attempts to attach the explosive charge failed. Google it.
„Tempo Limit on the autobahn“
*laughs in german*
haha car go vroom
some deutsche autobaehnen(?) have speed limits
Then the battery powering the screen goes out while going 40 mph.
so of course there is a backup
Alexander John pedal powered generator?
Joseph Gordon probably Not that would slow you down
y Nyggi, the power usage of the screen is probably less than 5-10 watts, wouldn't slow you down much, but it would add complexity for a generator
TheGerm24 they are trying to break a world record. 10-15 watts less for the screen are 10-15 watts put into speed
I love the idea but the only people who can afford it will prefer to drive their Bentley's to work haha
You are voting and developing things with your attention. Be active on the fields what you want to make easier. Already we have hundreds of technology at our hands what was only a dream even decades before.
No, there are a couple cyclists out there who are willing to spend more on a bike than on rent/mortgage.
I paid €2k for a used velo. Even with old and slow machine 200 watts gives a speed of well over 30kmh. My only problem with the older machines are the rider space, a new machine Bülk mk 1 drove from the southern border of Germany to the North border in less than 30 hours, over 3 hours faster than the previous record.
Curious how this performs uphill.
It has different gears in them, similar to a mountain bike.
Recumbent bikes do not do as well up hills. Although it's far more aerodynamic than a regular bike and faster on the flats, it's hard to get leverage and recoup other muscle groups... That's how I understand it at least. When I'm climbing hard on my bike, I'm using my core and upper body quite a bit.
Curious how this performs downhill.
@@AndyBlackburnart too fast and too little control
Dutch engineer: What's uphill?
Love this. I love recumbents and velo's.
id love to ride to school with one of these
Well you can, they're just not very cheap. But it's a perfect replacement for a car, unless you live in extremely hilly areas (let's say >10%)
I could really see this catching up with the techies in SF. I would love to ride this to work. SF already has special lanes at some places for “neighborhood vehicles “.
9:16 Why he lookin like a super villain here
As an urban planner, commuter biking fascinates me. But from my experience there is so much negative pushback when the construction of bike/active transportation infrastructure is suggested. Technologies like this may be able to open the door to serious AT investment once safety, cost, and other factors are worked out.
Amazing that you can go so fast with just the strength in ones legs.
Chris Stephenson ride it off a cliff, and you can get it up to 120mph easy
Yes. Please make the Velotilt available to order. *proceeds to throw money at computer screen*
The VeloTilt was never finished I believe, but there are nice alternatives!! If you don’t know where to look find me @365bcycle on twitter or Quest4Dynamics on instagram
Kevin Johannes it was never finished? That’s a shame.
@@briannam1082 Well there's news again. The VeloTilt plug is being shipped to the US, Fayetteville. Mike Lecka, someone who has been building velomobiles for a good few years already wants to continue the project.

amazing bike!!!! want to have one❤
Appreciate your attempt !. I really love your creativity. Amazing ! May God bless you !!!👍
Its amazing, good work man...
This seems like a great invention but are there any safety precautions in place for crashes?
The german manufactured Milan has a Formular 1 like secure cell - many of this high speed bikes selled and also some accidents known, where the driver has had only scratches even if biscyle was total destroyed.
Did you see the foam at 6:50 that foam can absorb shocks when you crash.
The foam is about spreading the load . it ' s effectively a bridged double skin structure , so each skin can be thinner , saving weight & cost & the load is carried between the two by the foam ...... De Havilland did the same with ply & balsa in WW2 on the Mosquito ...... they even used the technique on an early jet ...... acesflyinghigh.files.wordpress.com/2016/02/img_3645-vampire-trainer-fuselage-900x600.jpg
Why is this a relevant question
Data Radar it’s wearing a shell
I wish I had that bike!!! If the whole world used those bikes imagine how great life would be. Less of those nasty accidentns and everyone keeping in great shape
Working on it! :-) I commute to customers by a fully human powered velomobile (up to about 30mi/50km one way), and trying to convert others into doing so also. There's more advantages than just everyone in shape and less accidents. We would solve a huge portion of our pollution issues in an instant if everyone under the average car commuting distance in my country (23 km) would get out of the car and into a bike.
Good video and good work!
Really dig the subject,thanks for posting, question, what was the height of some of the pilots/operators?
Fcuk breaking the world record, you potentially have a product here that could sell in millions worldwide.
Bright or possibly flurescent paint so it is well visible, add a simple electric motor to assist the rider and hola, you have an efficient vehicle, for even the regular folks to go far quickly.
i thought about that to using the rider to generate electricity powring a smaller motor would be a great idea
Bugsy C converting mechanical work to electricity is very inefficient. Converting electricity to mechanical work is really efficient. Converting mechanical work to well nothing and just using it is 100% efficient
Excess cars should be against the law.
Ydonkov breaking a record would get them more world-wide recognition, good for advertising
Ydonkov yep that's how I see it too! I want highways filled with vehicules like this!

@@solomu8772 You know plants live of Co2 right..?
👍 sehr schöner Beitrag. Ich finde es faszinierend mit solchen Geschwindigkeiten zu fahren, als Fahrradfahrer . Es gibt ja schon einige Velomobile auf dem Markt leider sind sie relativ teuer.
Excellent work.
Just add wings to this and you could fly! You would get lift off then land and pedal and then lift off again.
+John Python Not really. There would be major flaws including landing and it's maneuverability while in the air.
+cavan miller stop being such a disruptive person. Be more positve minded...PLSSS i miss this atitute so much on people.
:)
adding wings to the bike wouldn't do much and you'd have no way to generate lift till you touched back down... HOWEVER, a recumbent pedal system could possibly power the propeller of a small lightweight aircraft... Just like pedal car replicas of muscle cars and hot rods, I think it'd be cool to have a P51 replica built with the intent of a glider, then add a recumbent pedal powered propeller...
+〈LS〉 XeN Not to mention it's sealed shut with tape.....
It should be mentioned here that the record mentioned has been exceeded in this year of 2015 and there is a new "Fastest Bike in the World". The AeroVelo Team from Canada have done what this team did to the old record, blown right past it.These Dutch student teams have helped to really up the record however and are to be congratulated for their good work. Maybe next year they will take it back.
+Paul Gracey www.recumbents.com/wisil/whpsc2015/speedchallenge.htm
Where can I find more informations and videos about this team and the bike please ?
Incredible. So fast and human powered
Great project! Streamlined recumbent bikes with electric assist would be a great alternative to a car for shorter commutes. Economical, healthy and environmental benefits. (People with a long commute should probably move house/job!)
or take the train. you know instead of moving house/job.
Great design. We can only imagine how fast it would go, if there was an electric motor inside.
I think this design shape could be used for the train, motorcycle or bus too. It's a very useful experiment / competition.
I like the gearing ratio, I thought that was quite interesting, but I don’t think it’s a practical bicycle for most people, particularly if you live in an urban environment, where would you park it & how would you secure it?
@@theodorehaskins3756 like a car. this is a record setter, but you can have more room with less speed.
Where do buy one of these awesome velomobiles? How do I get it shipped to San Diego?
I have a couple questions.. how hard was it to go fast. i mean was it tiring to get this fast and another thing how long were you able to go once you reach this speed?
I wanna see this thing with Jens Voigt piloting
I LOVED this video. It shows what the human is truly capable of and shows the advancements in human ingenuity. I would love one. Although I would love weird as hell I would be saving money in the long run. But with American roads I think it would be useless for me to own one. The only way I could even think of owning one is if the US government made all the roads as smooth as European roads are. US roads and traffic laws are not really set up for bicyclists as it is so id feel unsafe commuting to work in something that low to the ground.
Outstanding vehicle!!!!!
Hi, would love to increase the speed of my Rans VRex. Any tips?
WHAT IS THE CARBON ( + NO2 SO2 PU....) FOOTPRINT OF THE MILITARY INDUSTRIAL COMPLEX?
Put Tony Martin in that thing for the average speed run, and then you put André Greipel or Marcel Kittel in it for a max speed run :D
Would love to see Jens-y have a go as well xD
Great little documentary.
So whats up with the velo tilt? Is it produced and how much is it? Or is it dead ?
I think that is really neat. I agree that recumbent are really fast. I read that they are banned from bike racing because of an unfair advantage. I think they should have a separate bike race for recumbent bicycles.
Yeah the problem with recumbent is when it goes uphill..
Thomas Lee Mullins they do
You can race recumbents no problem. They are not allowed in certain races for the same reason car racing has classes; f1, Indy, 100cc kart, le man.
Recumbents go up hills just fine. I've overtaken upright riders plenty of times on my recumbents.
Major issue I see is the visibility and maneuverability. Not to mention the fact that you cant stop on your own
the driver is probably an Olympic Athlete so for normal people you would need electric assist and self balancing electronics to make this work plus in the real world you have to be able to get in and out easily
Could someone tell me what the benifits are wearing cycling clothing..?
avoid wind resistance in the cabine i guess...
Awesome !!! Just Awesome...!!! I am first in line when they become available...!!!
guys i think you make enough money. no need to plaster the vid with 4 ads on load
FFW;
E-bikes are the perfect commuters for cities.
a moped burns less power, (in joules/watts) than charging a Ebike from a power plant. they just need to be held to the same emissions standards that cars are.
don't get me started on how solar panels go out in fives years or all the birds that winds power kills. >:C
Great video, thank you!
I was thinking, how would they solve the heating problem inside the bike body, especially for the consumer version.
Sacrifice a little speed and get ventilation in return :-) Works well!
This is awesome! Where can I get one?
nowdays a electric bike can go near 120 km/h .. I love the Science :D
+0BLACKESTFUN0 Even faster ! Some bikes can go up to 190-200Kmh :D
would be funny if the police tries to catch you :D and your bike goes 200km/h :D they like WTF :D
I was talking about motorcycles haha. :P
But yeah a bike Damn if that thing would go 200 it would fall apart. :P
An electric bike can go much faster than that. Creating one that will do 400 km/h is perfectly possible. What this is about however is traveling as efficient as possible, in this case also on human power. We humans are limited to about 2000w continuous from the strongest riders. Since we emit 75% as body heat, the strongest cyclists can put out about 500w into the pedals. Translating this into a speed as high as possible is the challenge.
@@0BLACKESTFUN0 They will catch you because even if your aerodynamics are good enough to let you go 200, during acceleration you're still limited to about 1000 watt from a strong rider, which won't get you there quick. I have been stopped by police however, for doing close to 70 km/h. They wanted to check if my bicycle is motorized.
This is a million times cooler to watch than the tour de france
This is a Great invention.
It's a bike, they have been around for a bit.
I'm liking the Cruzbike recumbent at the 11:50 mark
why hasnt anyone put wheels on a hot dog
Hayden Hoff they just did
too chewy
It's sad but I think the majority of people are just to plain fat / lazy to ever even consider riding a bike to get places short / medium distances away. When I was a kid that was how you got places. Never asked mom or dad for a ride. Now, As long as I could have something fully enclosed like that one with three wheels that tilts I would absolutely use it to get around. To dangerous though with all the crazy distracted drivers in their big hulking SUV's driving like maniacs to do unfortunately. Sad how "progress" is determined by how much we can make computers / machines do for us so we eventually won't even need to move..
jtkent28 This is dangerous? So is riding a bike with psycho rapist and kidnappers out there. Not to mention the shitty drivers.
jtkent28 If people are just too fat, then stop hating, stop judging, and decide to save the climate with nice comfortable light enclosed recumbent electric bikes for them, which use 1/100th the energy to get them where they need to go, and then they won't need the gas guzzlers. Put pedals in them too and they would have a chance at rehab-ing themselves. Bikes are NOT an all or nothing proposition, if they were it would look just like it does now, climate change, till we all croak. People will never go for it until you do, even if it kills everybody, because biking just looks too impossible to them. Look at the older people, they could never do it, but the more people with bikes of all kinds the more we'll build separate bikeways for them, like in Europe.

If Usain Bolt was riding that bike how fast would he go?
Mega fast.
He would break the sound barrier.
He probably wouldn't be able to stuck his deltoids in this :D:D
Sprinting muscles aren't the same as endurance muscles. It requires a different training technique. You might want to google endurance runners for different distances.
Xerkies slowly different muscles I know I do hpv for a team
This could potentially be a great sport.
That's what I was thinking--almost like a Tour de France type bike race, but with ultra-low-drag bikes that can reach highway speeds :)

I read it "Velotit" first, and my head started spitting pictures before i could stop it
And price?
Driving a car for few years lmao
It's actually the other way around. My velomobile is a €9000 investment (only 100% cost if you don't exploit the commercial possibilities, which is what my company is doing). It'll cost me about €400 of maintenance yearly. Insurance is minimal, there's no tax. I also stopped paying for the gym, although you could say I eat a bit more due to sporting more (every day). Now calculate what your car will cost you yearly including gas, insurance, tax, and - if you buy a second hand lemon - repairs: You'll probably spend about €2000 on the car and spend the rest of that €9000 >>yearly
I'd love to have one but with a seatbelt and a rollbar instead of a roof
It would be heavy as shit dude fuck that.
User Nonexistent:D What would be heavy? Aluminium/carbon fiber rollbar is what i meant
The bike because of the roll bar and the wind resistance would make it worst.
User Nonexistent:D A rollbar inside the monocoque doesn't disturb the flow at all.
That's if you could fit it in there.
very cool !
As someone who has ridden an enclosed recumbent for two years (using a model WAW 4th generation) there are some distinctive disadvantages: it's large and a bit cumbersome. It needs significant space to be stored. When it breaks down on route and you can't fix it on the road you can't just push it on so you need help to transport it. It can't be easily transported, it's a bit like a motorcycle, you pretty much need a trailer or a decent size pickup. It's very bad on uphills, it's a heavy bike and you can't put force downwards on the pedals like on a normal bike, uphills require lots of effort. You can't really fully enclose yourself and protect yourself 100% from the elements, your visor will fog so you'll always have to have air flow inside the cockpit and even than it will still fog up easily. Visibility for you and to others is an issue, you're not as visible (even with a flag on your velomobile) to others and you're also less aware of your surroundings especially when enclosed in the cockpit. A velomobile is very susceptable to bad roads, much more than a normal bike. You'll feel any bump or any imperfection on the road. It's loud and noisy inside, remember it's an enclosed shell, all vibrations and noises are amplified within the shell.
That being said, there's nothing faster than a velomobile but you need good clean straight bicycle roads. You can ride against a strong wind and you won't really feel it. It's a comfortable ride but as soon as you ride on bad roads you'll feel as if you're in a shaker.
Pinlock. Air suspension. You can push it (tiller) Some are pretty quiet. Velomobile =! WAW
Do a wheelie
The average velomobile can't wheelie, because the weight distribution is much better than on a regular bicycle. Some models can do a stoppie, I can blast off with a screeching rear tyre, like some cars do.

This is beautiful.
If it could compete in terms of speed, people would pay for this instead of a car. And then imagine in governments actually designated special roadways for motor-less vehicles. The more we push for a critical mass, the more gov'ts will listen. Keep on riding, my brothers and sisters! Demand your place on public-funded roads!
I hate critical mass. Take up the whole damn road and go ten mph. That will make motorists not hate us.
beautiful concept, unuseable in traffic.

Benjamin probably America
This is a racing machine. You wouldn't drive a top fuel dragster on the street either, cause running out of gas within a minute is a bit inconvenient. I cycle in a velomobile daily, also on bad roads - mine is a street model with full suspension, lights, blinkers etc.
it's not a mountain bike yo... but yeah, that thing wouldn't survive the appalachian roads and hills.
@@greedfox7842 This thing might not, it's basically a prototype. Don't know the Appalachian Hills so well, have been on various places between NY and Richmond (most Washington/Baltimore/Charlottesville), but don't really remember seeing anything there that my VM wouldn't be able to handle without problems. Basically if it's asphalt or hard sand, I'm fine. Grass and mud is possible but removes any advantage in speed, which is what they're for.
In that area, I'm not sure if I'd dare to cycle though, but that's probably also caused because I don't live there and we're spoiled here. If I would have to, I'd want one of these for the huge advantage in terms of weather protection; in one of these, I'm barely affected by extreme cold (0 Fahrenheit without a coat is no problem). 100F might be a bit less comfortable :-)
I've been to that DREAMS building a couple years ago in secondary school. It's really interesting, all those things there!
Did this ever get built? Is it in production?
So this was built to break a record? I thought I was seeing a consumer grade bike to replace gas lol. Nvm
when battery technology gets to a point where it doesn't take 5 times as much power to charge a battery than it takes to just burn coal for the same power output.
so, I probably said that dumb...
A coal (steam engine) would go father for the same amount of coal, by five times, than an electric car charged from the coal power plants that most countries use. and don't even get me started about diesel power plants or nuclear.

I absolutely can imagine me using a car with cameras and no glass.
Oculus Rift.
Doesn't make sense. Using the oculus in a high performance prototype like we see in the video would add too much weight. And for a commercial application in a speed-bike it would be too expensive and unecessary since those will have see-through windshields.
The bike on the video already has a camera and a screen on it. By using an oculus rift, or something similar, it would expand the field of view and provide better depth perception. Another option is to look at something like Samsung's GearVR. Rather than having the screen in the vehicle, have a slot that you plug your cellphone in to provide said screen for the direct video feed from the stereoscopic cameras.
However, I agree that if there is a lightweight, strong, transparent material, then the need for video pass-through becomes moot as one can simply make the entire shell out of that.
Ultimately, though, many people are likely too lazy to use such a device currently, and would prefer to use a vehicle that they don't have to power themselves to provide locomotion. In addition, storage space for things like the groceries or gifts for little Billy's birthday would be needed. Tesla's got my hopes on it. They're doing awesome things.
We actually looked into using an Oculus Rift, but found that it is really difficult for your brain to process the experience while keeping the bike rubber side down. Maybe in the future!
Always interesting to hear what effects new technology can have on other technologies, and ourselves.
Now just remove all the hills from the world and you got yourself something useful
That what the transmission is for ;)
Up to 7% it's easily doable in mine, and then you could add E-assist.
@Seb Ba if I can't go fast I'd rather have a regular bike for the better handling, or in some cases a fixie for the ability to stop and idle.
and as an engineer, most cars/trucks have a lot of extra bullshit you could cut off them without affecting the car part.
@Seb Ba what come to the west coast and tell me missy cities are flat
how long distance you may driving for use each Hamburger?
I remember having a race with "Peloton Pete". He was on a recumbent and we were on our tandem. He taunted us saying that tandems don't climb hills. He was half our age of course. Anyway over the next 60km of undulating terrain, firstly rising for 40km then falling for the next 20 we passed him on every upgrade and he could go past us on the downgrade. Although the recumbent was fast in good conditions he couldn't get the power out as efficiently in climbing. Our average speed was pretty similar. The next day he was on his roadbike and he could easily overtake us.
Designing the surface of the shell like the surface of a golf ball can increase speed performance.
That only works to gain lift with backspin which increases drive length. That's why it's used on golf balls and not aircraft.

"You're travelling faster than an automobile"... Yeah I guess you can for about 20 seconds, while being an athlete AND at a certain time of day so theres barely any wind. Yeah good like with that being the "future"
Even if they manage to get rid somehow of weather and being an athlete problems you would still probably need to have a shower after a ride so not really that usefull when driving to work or to meet up with friends. For now the project really doesn't look like a future in any shape or form.
Yea, I know. It's not like we can take anything from this at all. Either it all works or it's scrapped. That's the way our great minds have been working, right?
now no one need to workout leg when u have this 😂😂😂
Every liter of fuel that isnt burned is pure profit for all of us...
Petroleum producers have entered the chat.
something much less extreme, combined with the cheap and reliable 1000watt mid drive (ie geared) ebike set ups available today (i dont mean those dorky hub ebikes) would provide incredible performance. 80mph and 50 mile range would be easily attainable. no need for cars now. we just need a worldwide carbon tax. unfortunately the fossil fuel / car companies and their political puppet allies stand in the way of a livable future

The crash safety of these bikes is pretty terrible. The crumple zone is literally your leg, and there's very little way to change that without making the vehicle much larger, thus draggier and heavier. Besides, the low CG of these vehicles makes them unstable at low speed, and the long wheelbase and narrow wheelwells limit turning radius.
+Bill Kong Low CG makes it more stable...
Not exactly. Bicycles balance by moving the contact points in line with the CG. Higher CG means it takes more time for the bike to lean to a given angle, so you have more time to steer the bike to correct for it. An upright is like balancing a meterstick on your finger. Riding a recumbent is like balancing a 30cm ruler. It can be done, but it requires much more focus and faster control inputs.
The reason you think a low CG makes things more stable is probably by reasoning from cars or planes. In airplanes, the weight is supported from lifting surfaces, so if an airplane is banked, there is a torque acting on the vertically projected distance between the CG and CL. At a fixed CL and bank angle, it's easy to see that the torque in the direction of displacement is proportional to the height of the CG above the CL. If the CG is below the CL, this is negative, and the torque will be in the negative displacement direction, restoring the aircraft towards horizontal.
In a car, there are 4 contact points, so cars are inherently stable except during cornering, so that is what stability usually refers to. During cornering, the radial acceleration the car experiences acts at the wheels, so the shorter the distance between the CG and the wheels, the lower the longitudinal torque at a given acceleration, and the less the suspension deflects to accommodate.
Different vehicles respond differently to design parameters. That's why unicycles are built very tall.
a livable planet v safety concerns. i think your problem, like humans in general is not really getting things into perspective, or having the necessary sense of urgency, to put it mildly. which is why the human species is fucked.
with humans likely to become extinct in a few decades, (read limits to growth as to why) transport is a moot point at this stage. but its interesting watching humans creating lots of nifty new excuses to keep cars culture going. what the ipcc dont say is that 3c global warming is now 'in the can' so there is no carbon budget left at all, and in fact there is a 1c negative one to stay under 2c ! amazing they dont say this. might be bad for the economy i guess. 3c (game over) warming is guaranteed because current warming is 1.5 c (taking c1800 as baseline date) then adding 0.5 c on top for the 30 year lag, plus 0.5 c accounting for global dimming and 0.5c for all the positive feedbacks (very conservatively). with humans doing absolutely diddly squat to reduce emmissions at all let alone to zero, we can add another 2 or 3 c warming on top of that. but lets worry about how billions of humans, that wont be able to be fed, are going to carry on travelling long distances at abnormal, peon pleasing speeds, like it matters.
Um what about people with a family
+Johnathan Godwin Dude do you commute to work with your entire family? This is a good alternative for people who are going to work solo man. Many cars on the street are always 1 bugger driving a 4-5 seated car.
+Johnathan Godwin The vast majority of cars are on the road are single-occupancy. Solving for the majority makes more sense.
My kiddo loves his bike trailer. I saw a woman on the train the other day with three young daughters on a cargo eBike. Youngest on a front child seat, two on the rear bench seat. Common in Copenhagen. If we can engineer a 3,000lb machine to transport 4 ppl we can design a 100lb bike to satisfy the same need.
Amazing! Is it already possible to buy the velotilt?
maybe next year, velosRus.com
follow on facebook in most all velomobile walls. youtube channel: pushyhog. ALSO on recumbents dot com forum,,,,lm Carolina there.
So how much co2 you consumed to make the body
Why would I choose this eco friendly, fat burning mode of transportation?
-Fat American
Jarred Frost Yea why would I? I aint a hippy liberal! -Fat American
+Jarred Frost It looks awesome I want one.
-Fat American
+Jarred Frost So you don't get diabetes or worse cardio vascular disease
m9078jk3 my diabetes did not come from being overweight or consuming vast amounts of sugar,it was hereditary
tazztower44 ok to prevent cardiovascular disease and obesity then
leave it to the dutch to invent the fastest bicycle in the world...
Is there any way for air to get into the fuselage? It might be hard to breathe.
I ran the sums and something is wrong. 600W (minus 100 for rolling resistance) would equate to a drag coefficient of 0.34. That velo would have a much better drag coefficient than that. How did you determine your power output?
