Let's make a bicycle frame out of hydraulic rams.  

Now if you're new here I've done things with bikes  before. We've got the social distancing bike,  

we've got the jet bike, and we got the  bicycle of springs, where i swapped all  

the tubes for springs to make it go all wobbly!  Now if you like that sort of thing SUBSCRIBE,  

it's a lovely thing to do! In this  project we're not using springs,  

no, we're gonna use hydraulics, so it can grow  and change shape and do all sorts of funny things.  

Now usually I'll get a bike chop it up, adapt it,  add the things onto it. But I've decided i'm going  

to be using so little of the bike, I may as well  start from scratch. Now hydraulics are expensive,  

this video has a sponsor. It's sponsored by  Raid Shadow Legends, more of them at some  

point in the video. Raid Shadow Legends, because  no other Youtuber's ever done that before! Anyway  

Get yourself a cup of tea, relax here  is a nice cool calm build montage.

Now that, that is looking awesome. Right, now  a message from our sponsor Raid Shadow Legends.  

What has Raid Shadow Legends got to  do with the bicycle of hydraulics?  

Look Raid's a mobile game, with console level  graphics. Millions of people are playing it. It is  

simple, but yet complex, exactly like the bicycle  of hydraulics! Raid is a turn-based battle game,  

in which you control your characters otherwise  known as champions, and they are upgradable  

and customizable in so many different ways that  everybody's experienced would be completely  

different! I ain't time to play mobile games!  You can dip in and out of games anytime you like,  

and they are always adding new features,  like the Doom tower. Not this, this!  

Excellent! So I've got this new champion. Now I've  not just picked him because he's totally bad ass!  

He's got the same voice as the next-door neighbor!  What are you doing in the bath? So download Raid  

by scanning the qr code up here or clicking the  link in the description and if you're a new player  

there is lots of things to get you started.  You'll get a free new champion called Shelton,  

who's epic for the doom tower. oh! You'll get 100k  in silver, 100k silver that's a bargain! 50 gems,

50 gems! and three shards, so you can summon  champions immediately, as soon as you're playing,  

and also you'll be getting FREE things  in your inbox for the first 30 days. 

Thank you! Okay here we have a very strange  and very heavy bicycle. Now this thing looks  

absolutely fantastic, the stainless, steel the  black hydraulics, it looks brilliant! There has  

been a lot of machining go into this thing!  If anything I'm kind of more curious,  

excited for what this thing's going to be like,  because you can really make some very strange  

shapes with this bicycle. Letting it do  what it wants to do because at the moment  

because there's no hydraulic pressure in  any of the cylinders. They're just floppy,  

they're all right, you can barely keep it as a  bicycle, that looks like a bicycle without it  

just like kind of naturally flopping into some  weird and strange shape. Now making the bike  

frame is kind of only half the task here,  because now we've got to fit some sort of  

hydraulic motor hydraulic lines, some controls  to this thing, without it overtaking it and it  

seeming not like a bicycle anymore, and just  a lump of electronics and gadgets and whatnot.  

So how am I going to do that Colin, because  you know, because I want to keep it neat!

Right hydraulics people, this is where it's going  to get complicated. Now I've got this motor and  

attached it to this tiny little hydraulic pump.  I'm going to put that on the back of the seat  

tube. I'm going to fill the seat tube up with the  oil, that's going to be our oil reservoir, and  

then we need a solenoid valve so we can change the  directions in or out, and then we're going to have  

to have some sort of manifold where all the tubes  come from and hopefully the whole bike won't look  

a complete mess after this. Yep I don't know, I  don't know, I don't, I don't know, but I like it.  

Uh it's finished! Now it's covered in plumbing,  but I think this thing looks pretty cool. If that  

biked past you, you'd be nothing but intrigued. So then, got a reduction gear motor which powers  

this little pump. The seat post is full of oil,  but I've added this extra reservoir, because  

there's not enough oil in there to expand all the  cylinders, if you wanted to do them all at once. 

Now the solenoid valve, I've had  to make my own aluminium block,  

so I can get all the ports to come out where I  want them. The whole thing's plumbed up. It's  

got valves either side of each cylinder. BUT,  can I actually ride it, and what is it like?

You can feel the weight of the bike.  Right open the valve. Valve on.

Forks going up! With a flick of a  switch, we've got like a low rider.  

Let's try and lift the back up.

This is not a good idea. So the front forks and  the rear triangle, they work great. So I have a  

little bit of a check over, now it's time to turn  on attention to the center cylinders in the middle  

of the bike. Now to operate the cylinders on  this bike you basically just open the valves up,  

which correspond to the one that you want to  move. So if you want to move this middle one,  

I've opened those two up and then  basically, you just flick the switch  

and then it will and it will move. Now the  biggest problem we've got is there comes a  

point where the bike just loses all of its  geometry and completely falls to pieces!

Ah, We're back again! So can't do that  while i'm riding along, but of course it  

does mean the whole point of this thing is you can make some pretty weird shapes.

Ultimate low rider! Endo machine!  

Super long bike!

Super long and tall bicycle! Right this is all  very well Colin but can you actually ride it  

in any of these guises? Strange bike!  It literally feels like i'm gonna go  

over the handlebars and the whole  thing's gonna tuck in any minute.

I don't like this!

It's like I'm laying down on the  bike. No that doesn't work too low.

Just feels like it's going to break.

The bicycle of hydraulics!

It looks so cool! This is all very well  Colin but does it actually have any uses?  

Well there is one, you can bike up  or down hills and always be level!

There we are the bicycle of hydraulics!

What a thing I mean every time I look at it  I think it looks absolutely blooming awesome.

You probably saw it in the thumbnail and  thought that's awesome I'll have a look at that.

A couple of little extra bits, if you're wondering  why I haven't gone like hell in down hills,

or doing any jumps on it there is  a lot of flex and a lot of twist  

in the chassis or whatever you want to call it,

because there's so many joints and things  and obviously the hydraulic cylinders you  

so that does add up to a bit of an  unnatural and nerving riding experience,

and also the fact it is heavy,  it's very heavy! I've weighed it.

53 kilos! Yeah it's heavy, but that still doesn't  take away from the fact beautiful stainless steel,  

lovely black hydraulics, lovely bit of  plumbing, it's just brilliant! Now I've  

put links in the description to my other bicycle  creations, if you want to go and check them out,  

SUBSCRIBE, there'll be more things like  this. I'll see you in the next project.
