How To Build A Mountain Bike Mini Kicker | Blake Builds A Portable Wooden Jump

(upbeat music) (drill whirs) Welcome back you beautiful people and today's you're lucky day where I am going to teach you how
to build one of these! Whoa, yep. This is a mini-kicker. You can perfect your jumping skills on this thing, you can have as much fun as possible with your mates
in the summer holidays. So, I'm gonna teach you how to build one of these step-by-step but before we get into all of this
you need a few things. First off, you're gonna need one of these. A little machine to screw
in all those screws. Talk about screwing, get
yourself a box of these screws. These are four by 50 mil. These are perfect length to keep this thing structurally sound. You want to get yourself a tape measure to measure out all that wood
to get the perfect length cuts. You're gonna need to mark those cuts, so you wanna get yourself a good pencil, marker, pen, whatever as
long as it's a good marker.

Get yourself one of these.
It's a right angle ruler thing. It's got a nice, straight edge so you can draw a nice straight line, so you can get a nice, straight cut. Talk about cutting, you want
to get yourself one of these, a nice saw to get a nice,
clean cut in that wood. If you're a young chap,
you'll be using one of these.

But with some parental guidance,
you can use one of these. (power saw whirs) Then you're gonna need one of these to cut a nice, perfect angle for that kicker. (power tool whirs) Next up, materials. What wood are you going to
need to build this thing? First up, you wanna buy two planks of these two-by-ones to give it a bit more structural support. Next up, you want to buy
yourself some 18 mil ply. This is gonna be the
sidewalls of that ramp. Last but least, you
wanna get yourself some of this nine-mil ply and this is gonna be the actual takeoff surface. This is where you're gonna be riding and launching yourself out the top of it. Right! Let's get cutting,
let's get making, let's get this whole thing started.

Okay, this is the first bit of the build and this is the most
technical bit of the build. It's quite difficult as well but there's a few ways of getting around it and that is getting the
perfect radius on the kicker. Because you don't want it too steep but you don't want it too mellow. You just want to get it nice and perfect. So take your time when doing this because it's quite crucial. There's a few ways of
getting around this to get the perfect angle, the perfect
radius for that kicker. So you can get yourself a
nice flexy bit of conduit. A bit of PVC piping
would work really well.

For me, I've got a nice
flexy piece of wood that I can bend into shape, I can manipulate with a few screws to get the perfect, nice, round, radius and I'm going to show you how I did that. So what you wanna do
is get your 18 mil ply. You wanna place it on the
floor or nice, flat surface so you can start drawing out
that nice, perfect curve. Okay, let's talk about this 18 mil ply and how big do you actually, really need to really have it to build this ramp. So when you go into your
local timber merchant or D.I.Y. store, or whatever, you don't really need to get these huge, big pieces of ply because
you're not gonna use all of it. So I went into my local store, B and Q, or whatever it was to
get this piece of wood. It's an 18 mil ply so it's about 610 wide millimeters by 1220 mil long. So, it's the perfect length and size to cut two sides out of this thing. So, I can get both
sides cut for this ramp.

So now, let's move on to what the lengths you need to actually cut
it, start measuring it out, start getting that curve,
'cause that's super important. So, the length of the
ramp I'm gonna be making is around, it's gonna be,
it's gonna be 40 inches. And that gives me an eight-inch
overhang on the back. So you don't really want to have your ramp with a straight back end
because it's gonna move. So, you need to give it
some structure supports. So, what you wanna do is keep eight inches out the back and then you will taper it all the way down from
the top to the bottom so that will give it a nice cheese-wedge looking shape so that
it wouldn't fall over.

Okay, so now I know the
length of my ramp, 40 inches. I know I've got an eight-inch
overhang out the back which I'll show you that later on. Right, next bit is to
start getting that curve. So, mark that. (pencil marking) So that's 40 inches from there to there. So, that is the ramp bit. So this where you're going to
use this. This is important.

So the next bit is you want to know how high you want to make your ramp. So, you don't wanna make it too tall because this is, you've
only got this much. You got 610 millimeters to play with. So what I'm gonna do, I'm gonna work in inches because it's pretty easy. So from the bottom, this is the bottom.

I'm gonna make an 18-inch high ramp. 18 inches. So that's the, 18
inches is the top of my ramp. You wanna get one of your screws. You wanna drill it on
that mark, 18 inches. So this top screw is gonna
be the top of your lip. (power drill whirs) Next bit, you wanna get this curve. So you know your curve
is gonna start there. So you want to, that's
gonna be your fixture point. Screw in that. (power drill whirs) So, the next bit is, you don't want to go all the way
to the end of your ramp. So what you wanna do is, you want to measure in over here.
I'll say two and 1/2 inches. Two and 1/2 inches is going
to give enough room there, so you can continue that
piece of nine-mil ply all the way onto the ground because you don't want to
have a step onto your lip.

Next step is get one of your screws, put it in at that two and 1/2 inches. (power drill whirs) So take a look at this, now with that fixed point there
and this fixed point here, you can get your hand, get your fingers. Move that piece of wood in so you can start to manipulate that
bendy piece of material. That's important. It need to be flexible. So this piece of wood is super flexible, it' perfect for it but
you can use PVC piping which is another great piece of material to use to find the perfect angle. So what I'm going to do is,
I'm gonna spend my time, get my screws, this is the other screw.

I'm gonna get this screw and I'm gonna move it around, look at it, and I'm gonna screw it in place and get
the perfect, perfect line. I'm pretty chuffed with that. So the next bit is, put
it back down like that, grab your pencil and
you wanna mark this now. You wanna mark this line. (upbeat music)
(power drill whirs) Alright, just to recap,
it's 18 inches high. I've got my curve using that flexy bit of material wood there. It's 40 inches long and I've left eight inches on the end which I'm gonna cut from the top all the way to that bottom corner and
that's gonna give it a nice wedge on that to
give it a bit more support when you hit it so it
doesn't just fall over. Right, now next step. jigsaw. So before we get started, I wanna mark out this wedge on the back.

(pencil marking) Done. So, this is gonna give me
that support on the back. So this is the back end of
it I'm gonna be taking off. So this is going to give it a little bit more support when it's on the floor. A quick tip before you start cutting, don't cut that line
because if you cut that, you won't be able to get the other half of the kicker from this
side because you'll cut this bit, you'll take
this bit out, you flop it over, you can cut the other side. But I'll show you that at the
end when I've cut this bit. Right, don't cut down there either.

(jigsaw whirs)
(upbeat music) (saw cutting) The next step is, get this board. This is the kicker, get this bit and place it on the line. Perfect. Perfect. Perfect. Get your pencil, run it all the way, take it off and you've
got the twin to this one. (jigsaw whirs)
(upbeat music) Okay, so now we've got our two sides they're matching exactly the same, they're twins so they're the same. Now, I'm gonna measure up these bits, then I'm gonna cut and put them in here. So those two-by-ones,
I'm gonna put in here to give it a little bit
more structural support. So this is the fun bit, this is where, it's a lot of cutting so run time lapse.

(upbeat music) Got my nice little blocks here. I've cut eight of them. What I'm gonna do, I'm gonna
place one right down here, as closest to the floor as possible. It also gives that nine-mil ply a bit of support, so that goes there. And then from there, I'm
thinking, 10 centimeter gaps. Okay, so I've measured out where I'm gonna put my little strut braces underneath the ramp to
keep the nine-mil ply nice and sturdy in there so I
can ride it at high speed. Right, next up do the
same to the other side and then start screwing together. Which, uh, is quite tedious but I'll make sure to do a good job of it. You wanna keep them planks nice and level because you don't want
to have a wobbly kicker. So it's super important to take
this bit a little bit easy. You don't want to rush this bit because you want to make sure those planks are level with that curve,
running up with that curve.

If they're not, if one's
higher than the other, it's gonna feel a little bit uncomfortable when it comes to riding it. Likewise, you wanna space these
things out super carefully. You don't wanna have big gaps. You don't wanna have small gaps because it'll feel like
you're riding over a grid. Oh it's looking good! Look at it! Whoa!
(upbeat music) One more screw and then we
can put on the nine-mil.

Look at that!
Look at that, it's sick! Now, to put the nine-mil ply on. Look at that. Now this is a hard bit so if you've made it a super steep
kicker then bending this, you might break it so you
gotta be super careful with this when you're
manipulating this into place. So what I like to do,
is I start at the top, put a screw either side because you wanna keep it level all the way down whilst you're screwing in through this, through the ply, into the wood. Okay, a little tip for you so you know where to screw in through this wood. Because you don't want to just be screwing into nowhere or guessing and having loads of holes, and it looks like some crazy-ass cheese. So, what you wanna do is
you mark a little score on each plank then you know
which the center of them is. Now, it gives you a good
indication where that strut is and then you get a nice
bit of long straight edge and you can lay it on
that and you can get, you can know where the plank is gonna be.

So, now, screw at up the
top, screw over there, and then slowly walk it down so you can get a nice, even edge and keep it on there so you just don't crack this bit of ply. And then I think, I think we're done. Now, this is super important. You make sure you get
this lined up really well because if you don't, it's gonna go, the piece of wood's
gonna be a little bit off and it's not gonna look good. So take your time in doing this. Don't rush. I know it's nearly
the end, but don't rush. It's gonna make some cracking
noises but it's fine. (plywood cracking)
It's fine he says.

Ah yes, this bit is super, super tedious. But you wanna take your time on this and be generous with
putting in those screws because you don't want that nine-mil ply to be popping off when you're riding it. Also, you wanna take your
time lining it up as well because if you don't
line it up really well from the start, it's
gonna be a little bit out at the end or too much
and it will look ugly. We're finished, we've
finished the little kicker. It's all complete. It took a bit of time but you can't really rush perfection on a little ramp like this, so you wanna spend your time doing it cause it's fun! Plus, you can just build one
of these on summer holidays.

Summer holidays is coming up, so you can just spend a few days building one of these a few hours, building one of these and you can just go out there for hours on end, perfecting
those jumping skills, and just having fun with your friends. Right, let's do a little walk around. Got some nice 18-mil ply
on the both sides there to give it a nice rigidity. We've got nine-mil there for the lip and all this struts, look at this. (laughs) This is super sturdy, super strong. If you did have a little bit of wood, a little bit more ply, you could put it on here just to box it off a little. But just to give it a
bit more of an aesthetic, an aesthetic-ness, aesthetically pleasing. There you go, give it a
little bit more of that. Right, now we're just gonna go. What I'm gonna do, I'm gonna chuck this in the back of my Jeep,
I'm gonna chuck my bike on, I'm gonna get in some
gear and I'm gonna test this thing out on the streets.

(upbeat music) Right, woo!
It's finished! So, I've come out but before I left home, I thought I'd put a good
coat of paint on this ramp to make it a little bit
more aesthetically pleasing. It's grey I know, but it's all I had. I've got one more thing, one more thing to make it official, G-M-B-N sticker. G-M-B-N, D-I-Y show has just started. Look at, there you go!
Ha! Ha! Alright, now let's send it. I'm gonna test it. I
haven't tested it yet. So, here's a nice little down ramp. I'm gonna make a little step down gap and I'm gonna put it, put it there and send it into there. (snaps fingers) (bike tires whir) Wow! Wow! That thing works a treat! Oh! Nice pop! It wasn't too
steep, it wasn't too mellow.

Kinda went too fast into it. Let's get a little bit
more comfortable with it and then maybe we can
bust some tricks into it. (upbeat music) Hahaha! This thing's cool! Right, let's do a trick. What trick? Tuck no-hander? Alright, tuck no-hander coming up. (upbeat music) Nice! Right, now I know it works, let's move it. Let's spice it up a bit.
I think there's a step up to a little concrete
bank thing down there. So follow me. This is the step up. I'm gonna
bar-spin up this step up. (upbeat music) Look at this line that
I've just scoped out.

So, I'm gonna put the kicker right there. I'm gonna jump over this,
I'm gonna go down there, and then I'm gonna drop into that little slope on the
edge of the car park. (upbeat music) Alright.
(wood thumps) Let's do it. Hohoho, wow! Mini-flip, turbo-flip
on a mini kicker, wow! So, hopefully you enjoyed
