Several things. Rear wheel steering is always harder to control. You need to slow down the steering to reduce the steering input. Possibly even limit the amount the rear wheel can turn. Another issue is weight balance. Ideally, you want more weight on the driven wheel. I think the longer wheelbase helps you out here. I wouldn't go shorter. It's certainly very challenging trying new concepts in the cycling world! I built my own front wheel drive, front steer bike that works well. But I went through several prototypes first!

The bottom of the forks are behind the steering stem. I think if the bottom of the forks are in front of the steering stem it will be easier to steer. Make make the rear steering arm longer to slow down the steering. I'm sure you are on top of this already!! Cool video!

Hi. By having the tyre/road contact point in front of the steering axis you have removed the self castoring action of the steering, and of course this makes it very tricky. I believe if you angle the steering axis the other way (i.e. forward) I reckon it will work, and it will have the added benefit of 'castoring' again. Also, thinking about when riding a conventional bike, when you begin to lose balance to the left, your C of M (centre of mass) is moving to the left of a line between the two tyre/road contact points. In order to correct this imbalance, you move the contact point of the front wheel to the left so that your C of M is brought back into alignment with the two tyre/road contact points. And vice versa. I am therefore wondering if perhaps your steering should move (the 'new' steering wheel) the opposite way to how it is now (in the video). Just my thoughts, but in any case, I'm sure you will get it sorted out. Regards Mark in the UK

Next up - reinvent the wheel, but make it Square, and sell it to Canadians, buddy.

I always like the way your mind works through your conceptual builds. It’s how we learn and grow our ideas.

reduce the throw of the steering. the wheel moves more than the handle bars. i also noticed a wobble on the rear steering wheel when you did manage to go straight. maybe a steering dampener like there is on some motorbikes to help prevent the death wobble. great build and great potential

This is like driving a rear steer forklift. Fantastic build.

There are bikes utilizing these mechanisms already, but it's interesting to see them put together like this. I think it could work. Bullitt from Larry vs. Harry uses the steering mechanism to transfer to the front wheel (it's my daily driver) and it feels amazing. Black Iron Horse 3 wheel cargo bikes use the rear wheel steering in a similar fashion also... But a 3 wheel bike is MUCH harder to tip over. On another note: I'd be curious if you'd consider putting Fat tires (4 inch wide) on a Bullitt cargo bike...? I have been playing with this thought for a while but I'm nowhere near as good with welding aluminium (especially if it comes to sturdiness of a cargo bike).

Well done, you just invented an unstealable bicycle

Superbe invention, il suffit de diminuer l'angle de braquage arrière et le tour est joué. Exemple : braquage avant du guidon 45° ne fait braquer à l'arrière que de 25° (chiffre au hasard), mais c'est ça l'anglé est trop important a l'arrière pour être stable.

Your work is always fantastic and very interesting to look at. I can't read the English subtitles right away, but I can understand something in the video right away. I'm watching this channel from Japan! I'm rooting for you.

You laughing like a little boy warmed my cold heart just a little bit. Thanks for this it was brilliant. 😂

Realmente eres uno de los mejores ingenieros que he conocido en mi vida... Allah Azza ua djalla te bendiga a ti y a tu familia... mi hermano!!!

Спасибо за работу, интересно получилось 👍

Possibly the greatest sport/trick bike ever created. A super fat rear tire would stabilize it easily

Those "safety ditches" come in handy. Great job, and fun to watch!

Great build :) One thing that could maybe work would be to add a little bit of steering (5-10° maximum) to a long cargo bike. But this would need a special rear hub, able to both steer and drive, and enough chainline to clear the tire in curves. This could make a super nimble long cargo bike.

You are sick! Best bike ever! Do more. I'm fan

The "Falling in the ditch" scenes are hilarious!😂😂

You should try to make a bike that steers with both wheels.

عمل رائع جدا لكن عليك تطويل مرفق العجلة الخلفية لتحكم أكثر في التوجيه تصميم مميز

Спасибо за труд автору!👍

I really wanted this to work for him. Great skills and boldly innovative. All the great things came from somebody at least first trying.

МашаАллах. Дал беркат дойл хьёх. Ма говзал елла хьун Дала. Дал аьтту бойл хьа брат

Welcome to the inventor Monther from Saudi Arabia. I see that you put the rear wheel in a vertical position on the chassis, because the reason for placing the wheel in an inclined position is for ease of steering. I am very happy to follow you. I wish you more creativity and happiness.

Скоро миллион 👍🏼 Ма шаа Аллах

I like the way your channel, shop, skills and even your English has been evolving! Keep up the great work! Love watching your projects! Greetings from a Bulgarian in Florida 👍

I think you should ship this bike to Sam Pilgrim. He is the only one that could use this bike. :D

This is a bike like a forklift😊 exelent work.

simply amazing

The fun and joy. That's what matter 😂🥰

Add a steering damper to stiffen up the steering. The other thing working against you is balance. If you shift your position even a little the bike reacts a lot. You steer bikes by leaning to one side or the other and don't even need the handlebars other than to hold onto them for the vast majority of the time. Make the steering really stiff. I think that will help quite a bit

Что могу сказать, ко всему нужна привычка! И на обычном велосипеде, хоть раз, да падал каждый!)

1. Why 2. Interesting concept and it looks cool 3. You gave me an idea. Could you make it (or another bike) with traction both at front and rear? I think it would be interesting to see how it ends up working.

he should go with this bike in public and let others to try to drive it

Вы батенька техноизвращенец😁🤣🤣👍👍👍

maybe adding more rake on the rear fork would make it less sensitive .

Excellent proof of concept, for the regular bicycle.

Hello. Very interesting bike project. I follow your creativity. My advice is to change the lever arm on the handlebar and on the fork of the swivel wheel. You will get a change - the steering wheel turns a large angle, the wheel turns a small angle, handling should become better. Good luck

I like that it folds up and doesn't take up a lot of space if it was normal I would buy it

Acredito que se você deixar o CASTER POSITIVO na roda traseira(da mesma forma como ficaria na posição dianteira), vai melhorar bastante a dirigibilidade.

For so long I thought I was the biggest crazy guy!!! ✌👌👍

Harika fantazi olmuş harikasın

You need to look at the trail of the rear fork - the caster effect - to make the steering more stable.

🤩 The energy in this video is contagious! Loved every moment! 🌈💃

That was the funniest video that I've been watching on the entire UKposts 😂😂😂😂😂😂👍👍👍

Great bike idea, I think if you set the back steering fork straight up and down that will get rid of the easy rider effect. Then also your back wheel reacts to quickly. If you bring in your steering joint more to the center next to the center you won't have that flapping around of the back wheel. That way if your handle bars moves a little back and forth from peddling the back wheel won't react as quickly to it. Also maybe put a limitor on the amount the back wheel can turn left and right. Like a fork truck with the wheels in the back it does not need much to turn as you drive. But it is always easier said then done but I have build a lot of bikes and customized motorcycles also for fun as a hobbie because of working in an aerospace engineering r&d lab fabrication machining and welding job. Always felt like a kid in a candy store. The more you build stuff the more you learn, and then your old and have to slowly give up things you love doing because of other circumstances. But keep it up, love watching your video's. You have a great talent. And open that garage door when your painting and welding those fumes will kill your brain. Put a suction fan in the garage wall to suck the fumes out. I was born in Arnhem the Netherlands and moved to California when I was 6. So from a former Dutchman, je doet geweldig mooi werk 👍. Plus you have a fun attitude making your films.

You can tell by the laughter it's a kind of fun and joy you can only experience when you build stupid stuff. Man I love it!

The front wheel steer naturally keeps the bike up. The turns actually assist you with keeping the bike from falling, however, if you put the turn in the back, the turns force you to fall. :D

Let’s try it - freak bikes are for the fun!

I'll be following your next work.

Me encanta tu otra bike.

I very excited to see the second version 2.0 with another wheel on the front for equilibrium control I bet it's all you need it to add 😉😎

That is some sick engineering, bravo!

Нохчи мот биц ца бина Аш Вежари👍

Аллах1 Дала аьтто бойла брат ❤

La práctica constancia lo lograrás, muy loco e innovador tu bike. Exitos en tus otro proyectos.

これはスゴすぎます！！ ぜひ完成させてください。

Х1о гараж чу вит мегар дац)) дик ю 👍

Too bad it didn't work out. Happy you finally built your idea to see how it worked. One must free those demons so they don't haunt you. Keep following your dreams. Man must follow his dreams to be happy.

Friend... make a trike with two driven wheels in the front... And one steerable wheel at the rear!!!

awesome ! can't wait

Поздравляю, вы заново изобрели велосипед. :)

The main issue is that your centre of balance and the bikes axis of rotation are backwards now as well.. In a conventional bike, your centre of balance is behind the bike's axis, which allows you to turn the handlebars and stay in balance. With your new design, you are way ahead of the bike's axis and because of this, all attempts to balance are basically too late and you fall over. It is possible to learn to anticipate and moderate your steering inputs, but, like those trick bikes with reverse steering, etc it's something that you have to practice over and over before your mind and body adapt.. Instead, if you want a bike that anyone can ride that is front wheel drive, your best bet is a motor in the front wheel with some sort of generator/pedelec sensor so that the front wheel gains correlation with pedal inputs.. You could probably also do it with some complicated arrangement of chains, cables and belts, to account for the front wheel both driving and steering, but the mechanical losses would be huge, so an electronic/electric assist is probably the best bet... Or, if you want to keep the existing rear steer configuration, some means of moving your seating position rearward over or even behind the rear wheel would probably allow you to ride the resultant bike more easily.. Shortening the bike would also help as that rear wheel is just way too far back meaning any turn of the wheel is amplified

beaucoup de génie pour un un vrai casse gueule! Bravo tout de même

felicitaciones, de los varios proyectos que le he visto crear en dos ruedas esta bicicleta ciertamente es la mas etraordinaria, creo que solo le falto considerar el radio de giro de la rueda guia, ya que esta al estar atras produce un movimiento mayor y por ende dificulta mucho mas el contro del vehiculo, supongo que esto no le impeira en el futuro hacer una version 2.0 donde mejorara por mucho este tema y probablemente luego saque una version 3.0 con asistencia electrica. por cierto al ser un nuevo concepto de pedaleo y equilibrio quizas al principio debio contar con un par de ruedas de aprendizaje, pero igual muy interesante proyecto

the pivot point of the swivel wheel I think it should be vertical to the plane of the road and as you have or a little more camber the swivel fork itself and the handlebar lever with less radius than the swivel fork coupling then I think turn less sharply With the little that I see in the video, I mean details of the position of the turning lever. For example, the stopped video seems to have the handlebar turned fifteen or twenty degrees and the wheel is more

EXCELENTE ASI ES COMO SE CREA Y SALE ALGO SALUDOS DESDE CENTRO AMERICA

I think if you can add some resistance (so you need to put a bit bore force on the handle) to whe wheel, i think this could work. Most of the current problem seems to be that the bike wants to 'death wobble' if you can minimise this, I think this bike would work better, or change the controls (dont know what to).

Great job on the build. I will be curious on how long it takes you to master riding your new rear steer cycle. I hope you keep us updated. Again.

You need a bigger rake on the rear steering wheel, as with castors that self align straight. Also add a small pneumatic piston and cylinder will help!

Crazy! Great vid as per usual

Необычная и интересная работа. Она стоит того, чтобы довести эту идею до ума. Возможно могло бы получиться более интересно внешне и могла бы увеличиться устойчивость при управлении, если сделать на оси управления двойную вилку с двумя колесами и доработать ход руля.

Bro, l laughed more at your bumbling on the highway than at a complete season of any american standup comedy, you made my day :-)

Молодец ! Крутая идея ! Попробуй два колеса ..на выбор спереди или сзади.. Быть Добру ! Спасибо !

Haha, that crossroad where you tested the bike is basically my backyard

Your tee joint welds at 4:13 are amazing. My joints are quite literally gone after I've had at them with a tig torch.

❤❤ from Nepal 🇳🇵

You did it well again. Congrats.

Brilliant 👏 😁👍

Thank you for including the faceplant into the ditch… Great Video

It seems to me that, stability-wise this is the same as riding a fixed gear bicycle backwards. There are people who can do this of course but it takes practice to get the hang of it and it isn't stable. In learning to do a trackstand I found that correcting for balance in the backwards direction is only possible for small corrections. For large corrections it is not recoverable; instability sets in. However, rear wheel steering is possible and stable for tricycles (see black iron horse tricycles and others), where balance stability is not an issue.

SPEED WOBBLES like nothing else😱

Brilliant

Love the concept! Can't wait for the video!

t'es vraiment un fou j'adore, continue

It almost looks like there is a small amount of play in the steering rack of the bike. Maybe add a gas strut (like the ones on car hoods/ bonnets) to control the wobbling? It may also help with fine steering adjustment. Or it might not do that.

Можно сделать платный аттракцион,кто дальше поедет😂

I also wanted to redesign my bike to match the weight of 160 kg, make the rear wheel wider and the front wheel narrower, and the spokes are 3 mm per wheel. Bicycle road off-road, for people with a lot of weight...

What an awesome concept, build, and video. You had me laughing out loud going headfirst into the ditch not once, but twice. 😂

Good experiment and good test!!

It looks like you need to change the steering brackets so that you need to move the handle bars further and get less movement from the rear wheel steering. At the moment the slightest twitch in the handle bars sends the back end flying out. By changing the brackets so you have to move the handlebars further you should get a much smoother and easier ride. Please can you try to do a second episode? That bike is far too cool to end up in the scrap heep 😊👍👍👍👍👍

Thank you for making me laugh at the end!

Now everyone can know why on a bicycle the spinning wheel is in front. Bravo!!!

i feel bad for laughing as hard as i did watching you go headfirst into the ditch multiple times x_x XD awesome video!

You should do something with its handle so it's don't turn easily while beginning the ride. Overall awesome bike, love it

Thanks for the great video The bike is very well made. is it difficult to go?

I have noticed by test riding that its really wobbly especially the back

Я думаю нужно сделать редукцию от руля к заднему колесу, что бы оно меньше поворачивалось. А так же, ограничить максимальный угол
