- A lying motorcycle built in your backyard that features both-wheel steering is the RoHorn. And this is the most fascinating invention in the last 20 years.
That Akira style photo is beyond epic!
that it is.
Maybe that was the inspiration for the Akira poster.
A guy in Japan actually made that bike from Akira and it's fudging awesome 👍✌️
@@pizzyp Seen it. There's also another fabricator in Japan doing the same thing, albeit his design deviates from Otomo's Akira bike, but still a reclined design.
@@steampunkster2023
Other way around is more likely seeing as how akira predates this by more than 15 years
Really nice job - I'm honored - thank you for your enthusiasm!
nice
The Akira pose, at 6:55, was that your idea?
@@urdnal Yes! Used a forklift in an industrial area to take that shot.
Keep at it Robert! I've been riding for 50+ years and have spent many hours thinking of something similar to offset the high G effects of any modern fast bike with great brakes. I would love to see lap time comparisons with a well funded take on this idea..
I've always thought sitting ON the bike made no sense whatsoever. Once should work WITH physics, not against it. Great job on the bike! Would LOVE to ride something like this one day!
Dude's got his lathe in his kitchen absolute chad
5:40
This is the closest I've ever seen of a viable method to make an Akira Battle Bike. Because it allows for an engine of any size as well as allowing it to be made oversize to fit the pilot. If I ever had the money ...I'd contact Robert to make it.
I've been building recumbent motorcycles for years as daily drivers. I've built a lot of them, As long as your body is in the right position and the steering is not crazy, then they're pretty comfortable ride. I never built one to race, though. I've built them for friends also who absolutely love to cruise around on them. Got a RUclips channel full of them. I do admire this man engineering on his steering!
Thanks for sharing. The topic reminds me of some oil sheikh with an enormous garage full of supper cars. In the corner parked against the wall like a bicycle was I think a Kawasaki or some other more expensive bike. When asked about it he said it was a piece of crap, "if you drive a million dollar car it really feels like a million dollar car, the most expensive motor cycle doesn't feel any better than a cheap one." It kinda made me wonder, where is the innovation? If people with an unlimited budget cant buy anything there must be something weird going on in the sector. It is not unlike bicycles all looking like the heavily restricted tour the france bikes where recumbents got banned after (winning) the first race.
Perhaps you can turn a velomobiel design into a motorcycle. They are recumbent bicycles with an aerodynamic body that fully covers the rider and wheels. It's a challenge to get the weight down with human power, lots of things should transfer to motorcycles nicely.

OP: just saw your channel and subscribed! Thank you for mentioning it! Regarding the bike used in this particular video .. I had been trying to work out the handling characteristics of one that steers with both wheels like that, and the results seemed to suggest that the turning of the rear wheel would be a fraction of the turning of the front wheel (around maybe 20-30%) and that it would need a little rake on both ends. Interesting to see this guy's take on the BMW telelever suspension. (disclaimer: I am not an educated ME)
@@gabydewilde On bicycles; there's room for improvement it's just that in the US where you don't bike to get around the next biggest constituency is upper middle class brain trust type folks who need an expensive hobby and want to look like they're competing. That means the same 'optimized' bike that's really a result of the rules of a competitive sport none of them are competing in. There are other types of bike out there being put to other uses. Folding bikes, BMX, hauling bikes - hell, bakfiets/boxbikes are a great example of redesigning a bike to do something totally different and there are some really wild looking ones like the Carrie.
There was a video of a guy trying a recumbent in time trials: ruclips.net/video/zg7Kl0bQCR0/видео.htmlsi=TgEZoqAu9mpvqodJ
The fact that it's some dude just trying it for kicks rather than someone with real capital trying to overturn stuff says a lot about the rigidity of competitive biking IMO.
Dang that is the closest Kaneda Bike I’ve ever seen. Great job Robert Horn!
I think it would be great if this concept is used in cruising and touring motorcycles....Because it seems very comfortable for rider...
They were made in the 1970s in the UK and only sold in small numbers, comfortable but visibility is poor.
its aero is way better too!
@@adrianjayne6580 Yah. Minimal front area profile. Most motorcycles have the sort of drag coefficients you'd see on trucks with stuff sticking off them. There's a guy on youtube who's made a fuel-efficient fully faired reverse recumbent trike along those lines .. see Paul Elkins, economical gas powered commuter trike.
Brilliant. I'm an older motorcyclist and cyclist and intrigued by this design from an aerodynamic and comfort PoV and want to know more.
I have been interested in the "feet first" idea for years. Ever since I saw a Quasar displayed at a show in Batersea. Later I got into FF bicycles and still have one..
Anyone that has machine tools in the kitchen has my vote!!!!
Guilty 😎
Reminds me of “ Akira , Kanneda’s bike “
Love this bike, such amazing work.
I hope he continues with development.
I wonder if he rides it on the road. That would give a good testing.
I ride a recumbent bicycle.
I do notice a lesser stability at slow speeds. Also a twitchyness. This is far less when loaded up with panniers low down. I suspect his bike doesn’t suffer so. Especially with the vertical front steering axis, though be interesting to know if the rear wheel steering helps, a few folk have tried rear only steering with no real success.
My main issue is that it is difficult to turn your head and look around at junctions or behind. A good mirror definitely needed.
Thats it! Im building my Akira bike (feet forward bike). It's been in my head for years, now i make it it life. My first new project, once i get my apartment i begine production. Know what heck it, now!!
let us see your progress 🥳
You left out that most full size semi-trucks are more aerodynamic than a motorcycle. The foot-forward design solves that problem while lowering the CoG. It has to be the way forward.
See Paul Elkins (on youtube) and his gas powered economical trike. Vehicles with such low CoD & CoG are definitely the way forward. The designers of yesteryear were focused on getting past horses & steam, peak oil and climate change weren't on the radar yet - another thing they didn't have then.
I relly want an Akira style enclosed lay down bike, it's weird to me that it doesn't already exist
Laying not Lying or Lay Down Bike. Lovely concept and very innovative.
So on a conventional bike when I want to turn left I pull on the right handlebar, the front wheel turns clockwise (from above), tracks to the right causing the bike to start to fall to the left. When I reach the right inclination for the corner I relax the pull on the handlebar and the bike’s trail pulls the front wheel round anticlockwise until it has no slip angle to the curve the bike is now on. At this point the handlebars are rotated slightly anticlockwise from the straight ahead position.
The video doesn’t make I clear but I’m guessing that your 2 wheels turn in opposite directions so when you pull on the right handlebar, the front wheel turns clockwise and the rear wheel turns anticlockwise, but by a lesser angle. This causes the front to track to the right but the back to track to the left which resists the desired effect of the bike falling to the left. Because of the 2:1 gearing the front wheel deviation wins but it’s surely not what you want on turn in? Also both wheels are rotating the body of the bike clockwise generating angular momentum that will have to be negated by tyre contact forces before the bike is turning to the left (when it will have anticlockwise angular momentum viewed from above). When the bike reaches the right inclination for the corner, you relax the steering input, the front wheel comes round to slightly anticlockwise from straight ahead and the rear wheel comes round to slightly clockwise from straight ahead. You’re now tracking round the corner and everything’s fine but I don’t see you’ve gained very much; your 2 tyre contact patches are at the same angle to each other as the conventional bike, the only difference is your body is rotated slightly more anticlockwise compared to the ordinary rider.
More interesting, and the reason for this comment, is the issue mentioned above of transitioning between initiating the turn and actual turning. As you initiate a (left) turn you generate clockwise angular momentum around a vertical axis which has to be absorbed by tyre contact friction before the bike can be turning to the left. Tyre contact friction that might be in short supply, particularly in a racing situation. The same is true to a lesser extent for a conventional front wheel steering bike. However if you had a non-steering front and a steering rear you would not get this effect so you could potentially turn in more quickly. You have built the prototypes to be able to experiment with this.
Rear wheel steering would not be easy if you can ride a bike. To turn left you turn the handlebars anticlockwise, like a car steering wheel or a jetski. The rear wheel turns clockwise (from above), tracks right and causes the bike to start to fall to the left. When you reach the correct inclination, leaning to the left, you move the handlebars to slightly anticlockwise of straight ahead which brings the rear wheel onto the line of the curve you are now on. However the angular momentum around the vertical axis generated by turn-in is anticlockwise, the same sense as needed when in the left turn so the tyre contact patches have less work to do.
Both wheels steer in the same direction. Having the rear wheel steer in the same direction speeds up the inclination, reduces the amount of inclination needed for the turn, and kills "Weave".
Steering the rear wheel in the opposite direction from the front does the opposite of all that - it does some really evil things above walking speed.
@@roberthorn In which case scrub most of what I wrote. I considered both options - wheels turning in same/opposite directions and the opposite steering seemed most likely to work but there's no substitute for experience. I'd still be interested in the rear wheel only steering case though. tfr
LOVED IT ... LOVED IT .... LOVED IT.
That rear steer must have given you some late nites & lots of coffee 😎
Akira was 1988 with a similar bike with a low center of gravity. but nice to see it on the road
Dan Gurney in 1976 came out with a bike very similar to this design THE ALLIGATOR ... and raced it and was very successful ... it would be the most fascinating invention in the last 48 years
YES!! Been thinking about something like this awhile. Super low profile, ought to have very good energy efficiency. Unfortunately also too easy for cagers not to see it :(
Would buy one of these!
Best kitchen ever.
2:34 My aunt built a kit plane at home, in her backyard, decades ago, although admittedly she wasn't designing it from scratch to be a radical reconception of what an airplane should even be, so fair enough.
I love her already! :)
EXCRUCIATINGLY AWESOME YO!
KUDOS ON THE BUILD
What fascinates me about this frame is the engineering of the rear wheel, which can tilt the opposite direction of the front. This makes the turning quite nimble. I wish he would make a deal with the manufacturers.
Роберт, давно наблюдаю за попытками победить физику и управляемость мото🤔 Твои изыскания вдохновляют на попытку исполнить нечто подобное🤓 Удачи😉 Быть Добру✊️
So cool, I'd love to try it!
Virtual steering itself can be seen in OECs from the 1920s. The down side is that stability decreases rapidly as the steering angle increases. I think this is a good thing in that it allows you to control the steering angle within a small range by using the front and rear wheels for steering.
Nice experiment. The recumbent design could have very low drag. Try adding caster to the front "fork" to make the bike more self steering and balancing like on a regular motorcycle. Also, to decrease the turning radius in the corners, have the rear wheel turn the opposite direction of the front wheel. Pretty cool.
How weird, I literally just wondered this morning if a foot-forward/recumbent motorcycle could be raced. I didn’t do a search this was just in my feed 😂
GET THIS MAN SOME MILIONS
Cool, may this be the norm so we can all be Kanneda from the amazing technical marvel in animation called Akira.
God bless.
it's like a recumbent bike but motorized. good work
👍😎👍
Congrats you have figured out what a paradigm shift is.
I never knew that there was a recumbent motorcycle. This is cool.
There has been a small but persistent Foot Forward movement in UK motorcycling for decades. The Quasar made by Malcolm Newell from the late 1970s to the early 1990s made an appearance in this video. Other exponents include Royce Creasey and his Voyager project
Now this is pod racing!
I hope someone makes an Akira bike using this!!!
Gustav. Baum held 125 cc land speed record for NSU at 200 mph . using a feet forward design in 1954. He unfortunately died when using a250 cc engine.
Gustav Baumm was a brilliant pioneer, but he didn't go 200mph on a 125. His NSU 125 'only' went 150mph, with only 16bhp! The 250 got close to 300kph (186mph) IIRC.
@@pnblondon1087 I was going to say, 200mph! Seems... impossible, given
such an cool idea!
I am gonna copy this...!!
Amazing, ty youtube for recomend ths video to me
You see very similar looking bicycle over the Nederlands and some in Germany.
They actually are very handy for people with back issues.
nice work
Неожиданно и гениально , интересная идея.
Seen allot of people try to make Akira style bikes. But this is one of the closest ideas that could someday lead to a production.
I have to agree with Robert on the mystifying appeal of cafe racers. My particular pet peeve are the fenderless scrambler-ish builds. A single mud puddle would cause the rider to be sprayed with mud!
The Bohmerland is what this fine effort brings to mind.....
I like the stick or fighter jet control. I whould move that to a left-hand or right hand position for ergonomic reasons. Also, to accelerate push the stick forward, pull back to slow down or brake.
I whould also implement electronic stabilisation, so if one of the tires where to slip one does not fall over and slide across the road.
Reminds me of the concept of Kaneda's bike in Akira all too closely.
The Dan Gurney Alligator reimagined version 2.0.
Akira ❤
Always wondered what that lay down go ped was called :)
4:15 w2s go ped
리컴번트가 모터사이클로 구현됐네
가벼운 중량 작은 엔진으로도 대배기량 모터사이클만큼 빠르고 편안한 승차감을 제공할 수 있는 좋은 아이디어
Motorcycle buyers are the most conservative market on the planet. They think a faring is wild but a belly pan is “whoa dude!! Relax with the crazy!!”
I owned a recumbent bicycle and also could test a low rider where you sit only about 10 cm above the street. It is a total different way of cycling. Starting is not so easy but then the sensations licks in.
Watch….Elon steal this and make a cyber bike!!😂😂
great ideas man
I wish this video was longer 😅
play it again
Lying is what you tell your wife after a stint at the bar, this one the other hand is a recumbent or a feet-forward motorcycle.
Lie down is used when the thing receiving the action and the thing doing the action are the same. "He lies down" "I'm lying down" "the cat lies down". Lay is used when the object receiving the action is different than the thing doing the action. So you could use it with people if one person was holding another person and put them down. Like "He laid the baby down in the crib".
That said, it's extremely common to mix them up and use them interchangeably in the specific instance of talking about people lying down. Especially cause the past tense of lie is lay.
"I'm going to go lay down" technically incorrect, but such a common mistake that it sounds natural and is understood.
Good luck with the wheelies 😊
OK for racing, dangerously low for the roads.You wouldn't be seen in traffic. I like the engineering of it thought.
Love it and see some great potential!!! Gas or electric!!
To the Author, i would love to know more about the geometry number of your machine 😅 the geometry of suspension is what makes or breaks any vehicle. I have some experience with building racing machines, but have always wanted to build a sit down bike, ever since I saw the Japanese anime movie Akira, would love to know to know more, as it will take me quite a while to learn the intricacies from looking at the footage of your inovative machines😅 thankyou for your input into the modern world of alternative sit down two wheeled machines
Man I love japan Invention ❤️❤️
KANEDAAAA!!!!!! TETSUOOOOOO!!!!!!! TASUKETE!!!!!!!! lol Make it look cool, paint it red and I'd buy one in a heartbeat.
It is a copy of the UK’s Quasar.
Which was a better design than this.
See the National Motorcycle Museum example.

That shot @0:06 😎
The monotracer concept i quite cool looking
Супер люкс вариант моцик!
that is nice references!!!
Damn...I had that idea 20 years ago!!
He's correct. I've daydreamed about a similar abet even crazier setup myself with rear steering let the bike turn in and out of turns that much faster. Rear steer is a necessity on long wheelbase and or low cg bikes in much the manner that a long trailer is more stable but slower to change lanes behind an over the road truck. These designs will always bump up against the "race what's selling contingent" that until recently were funded much better than this individual. It's a shame he's not closer to Philly. I'd certainly help him out if not give him the machinery he needs.
Moto GP x F1???? sign me up!!!
I absolutely can't stand cafe racers and it seems like every E-bike being made right now is based on them 😬.
This video was great 👍
I want a Tetuso Motorcycle!
Sooo, a recumbent motorcycle? Haven't these been around, albeit not in excessive amounts
Yeah, loads of them and every one looks as dangerous as the last lol
I think the 2 wheel steering concept sets this one apart from all the rest.
@@countryjoe3551 that's what I thought after I posted this. I don't remember any of the others that had dual wheel steering.
I still don't understand the counter steer with a stick control. What was that for?
Mostly because the wheelbase gets so long you need the rear steering at low speeds so it can turn tighter.
@WeirdBike Who wrote the frog-bird-innovation analogy at 7:19? It's really good and I can't find a source.
The reason sport bikes are taller than cruisers is for lean angle. You can't lean as much on low bikes. That's the buggest reason we don't ride bikes like this. As a fan of akira back in the day and a motorcycle rider i wish it wasn't true I'd love kinadas bike
Why is it both wheels turning the same direction? 07:17
Why no mention of Britain`s Royce Creasey (again ex air force background)? He explored and developed the concept during the 70`s and offered a police version of the "feet forward motorcycle". I`m all for innovation where the drawbacks don`t outweigh the approach. To me, motorcycling has become a leisure activity and people ride bikes because they ARE bikes and not because they make sense to the rational mind on the drawing board - Still it`s good to explore
Aero and ergonomic.
I don't think I'll ever understand why this wasn't a regular thing.
Epic
AKIRA… They should build something enclosed esp. with the auto-balancing gyro available nowadays… 👍
I don't fancy riding this contraption on the road. Your head is far too low to see much in traffic.
Yeh, good point. But the bigger issue here would be to be seen.
based on a recumbent bicycle (optima orca, not mine, borrowed it) this is really not such a big deal. you quickly adapt. as for being seen, people often use a flag in the back, and modulated lights
another version of the Dan Gurney alligator. kinda like this one better
Great to see Bob Horn get some well-deserved recognition here, and there are some fascinating facts and great images. However, for those of us who know something about the FF subject (and have ridden a great many of them) there are some really irritating errors. And why do you persist in using some fake AI-based voice-over that mispronounces words (some of which are clearly mis-spelled in the script). Only a non-English native speaker would call this a 'lying' bike; it's not even a lying DOWN bike. It's a recumbent or a feet-first or feet-forward (FF) machine not a 'Fitz-forward' as the robot mis-pronounces it. And how could you mis-spell WHEEL as 'WHELL' in the headline too?! FFS! The first Quasar shown was not a real Quasar, it was the New Zealand-built replica with a different shape and a different engine. Most people do NOT think that the true Quasar shape is ugly. You could and should have shown the precursor to the Peraves Monotracer, the Oekomobil/Ecomobile of 1985 AND the all-electric MonoTracer of 2009. The Voyagers of Royce Creasey should be mentioned too (along with the NSU Baumm streamliners of the 1950s). And how could you mis-write the QUAIL event as the 'QUALI' FFS! And why not mention the All-American Gurney Alligator by name if you're going to show one? I could go on, but I'll stop now...
there's some valuable information here for anyone not knowing about any of those things. if you have more, please go on
Dan Gurney had developed a similar design long time ago
Everybody: recumbent pedal bikes are annoying and the visibility is terrible, but at least they don’t go very fast.
Robert Horne: hold my beer.
Recumbent bikes are banned from UCI racing. This is another motorbike category
I have long dreamed of a racing motorcycle where the rider would lie on his stomach with his knees bent, a bit like sidecar riders. Low center of gravity. Excellent aerodynamics. “Normal” handlebars. (Sorry for my basic English).
Your English looks fine to me.
Best conclusion in the history of conclusions
Also Frog 🐸
Build it with two narrow wheels up front that are still tilt steered, n' the thing will be an amazing commuter vehicle.
What would 2 wheels make better than 1 ?
a leaning reverse trike? the complexity compared to a two wheeled bike is really through the roof with this. caster angle, camber angle, scrub radius, toe, bump steering are just some of the things that gets introduced that really isn't much of a problem with only 2 wheels. i'm not saying don't do it, but considering how much of a headache this one is to make the special rear hub, the work needed to make your city recumbent motorcycle idea probably adds a thousand hours work. of course if someone else builds it for you this isn't a problem
