How To Make Your Own Cycle Rollers For Under $32 Or £20!


– [James] Yes! Victory is ours, Tom! The
greatest rollers ever created! ♪ [music] ♪ – [Tom] Rollers are great for training
but they can cost quite a lot, £100 or $160. So, here’s how to
make a set of rollers for just £20 or $32. Behind me is GCN’s
head of engineering, James. He’s going to show us how it’s done. – Can you bunny hop off, Tom? So you will need, to construct your roller
masterpiece, 2 pieces of 4×2, which is 10cm x 5cm,
if you’re working on metric. Six of these right angle brackets, a
puncturer packet, an inner tube, a couple of cheese lids, 3 rolling pins.
These are basic IKEA rolling pins but you can if you want to upgrade to slightly
wider rolling pins which will make your rollers easier to ride on, or get some
with stainless steel bearings which will make them smoother and possibly
slightly less flammable. – James, I’m guessing this one is going to
need a bit more than just a set of Alan keys. – Tom, this is very serious. It involves
saws. You’ve got to not cock around. Well, first and foremost, most
importantly, we need a pencil, which lives behind your ear. You’ll need a tape
measure, a drill, a screwdriver, a saw, and a pair of scissors. – Well then, James, let’s get started. – Okay, so the first thing we’re going to
do is we’re going to cut our pieces of 4×2 down to being 150cm or 5ft long. – How do you arrive at that? Do you vary
it depending on your bike? – It’s pretty much the same depending on
whatever bike you’ve got, unless you’ve got an absolutely enormous bike or a
child’s bike, you’ll be okay with about 150cm or 5ft.
Most moderns saws have got a 90° angle on them so it’s pretty easy to work out where
you need to cut so you just put it against your line there, draw a line across, – That’s going to get a pro tip graphic. – Turn your piece of wood over, draw
another line like that. There we go. – Now we cut here. So, just to recap, you
want to cut your lengths of 4×2 into two pieces of 150cm or 5ft. – Right. Now we need to work out how wide
the frame needs to be so you can fit your rollers in. Okay, we’ve got our piece of
wood here. We need to make sure it’s not that close because then our rolling pin
won’t turn. These rolling pins have conveniently got handles on that are a
little bit concave, so if things kind of work out. But it’s about that far. Then
just measure the distance there, which in this case is 17 1/2cm and then
cut some of our spare wood, that we had from our lengths
we were making there, to be the widths that we’re after. – Let’s do it. – So here we go. We have our basic space
for our roller. Like a box. So in my box of screws, I have got a
variety of screws. We’re going to be using some 4 inch or 10cm long screws to screw
the frame together. I highly recommend using good quality screws which are in
fact self tapping and have got maybe a little bit of a cutting edge on them,
because it means you don’t have to predrill, Tom. So you need two screws per
corner to make sure the whole thing doesn’t twist and fall apart. So you’ll
put one in the top here and one in the bottom. – Prop that in the top there on that end. – Cool. We’ve got a frame, Tom.
– Let’s get it rolling. – Right, next up, we need our rolling
pins. So we’ve got our basic frame, we’ve had a little joust with our rolling
pins, so now we need to actually attach them onto the frame, but before we do
that, we’re going to need to sort out our cheese. So because we’re using an inner
tube as our drive from the rear roller to the front roller, we need a
way of stopping the inner tube from falling off the side. So, Mike, our
challenger, has very kindly brought in his lunch. So we are going to slightly
cannibalize Mike’s lunch and turn it into something that stops the inner tube
falling off the edge here. So, if you grab that one, let’s sort of
pull the edges off a bit. Don’t have to be too careful about it. Do
have to be careful of your fingers though. So we need to put one of these
on the rear roller. We’ll be using a 29-inch inner tube. And we’ll need one on the front. So
basically we need two rolling pins with these stuck on them. You could use a bit
of cereal box as well. What you’ve done there is you’ve
increased the resistance. – Vegetable sandwich. Sort of. – Easy now. To attach our drive chain, our
drive system, which is an old inner tube what we need to do is take an old inner
tube, or a brand new inner tube, and then chop the valve off. – Here’s one I made earlier. – Wicked. – We removed the valve, so we cut
around it then we patched over the hole that’s left. – We’re going to keep this pin quite close
to the back, here. Now it’s time to start screwing things down.so we’ve got a right-
angle bracket. Give it a bit of a bend and hold it roughly in place, like that. Get
out some screws and start screwing everything together. Okay, so the second
roller, we’re going to put 30cm or a foot away from the center of this roller here.
And that gives you just the right distance between the two for most bike wheels to
fit in so that it will be moving the rollers around. Of course, if you don’t
trust us that a foot or 30cm is the right distance, you can always just pop your
bike in and check that it is right. But it is. So that’s all spinning smoothly.
For this bike, Tom, we’re going to need to put the roller,
just drop that down, about there. Because if we have it too far forwards, it
will drop out the back. Probably the easiest way to do this, would
be to screw in one side of these first, then we can stretch the band over it, and
then screw in the other side of it so it will be held in place. – Do you want the band over now?
– No. We can put our band through like
that, and stretch it in place. If you make a bit of a mistake on how far
across you’ve got something, just undo it a bit and give it a tap. DIY
Mavericks. Just move the roller band across a bit. Yes! Victory is ours, Tom!
So these rollers won’t be anywhere near as good as a set you could buy from the shop.
They’ve got a lot of resistance, They’re basically all around rubbish, but
you can build a set of rollers for £20. Now, we’d love to hear from you guys to
see how you think we can improve these, what we can do better, how we can stop
them catching fire, because with the power Tom puts out, they might fall apart. So
share them with your friends. Let us know what it is you think we can do
to make these rollers better in the comments down below. Bloody hell.
