Introduction: Make Your Bike ROAR!
Make your bike roar like a motorcycle using just a piece of plastic!
This is an old trick my Dad taught me, though I'm sure many of you have done this before. It will make your bike make a sound like a motorcycle when you go, and the faster you go, the louder it gets!
Stuff you'll need:
A piece of plastic, like an ice cream bucket lid.
Tape, duct tape works best, remember, this is on your bike so it will be outside.
A bike, of course.
Could someone make a video with the sound of this thing? I would make one myself but I'm on dial-up so I can't upload video.
Step 1: Make the Flapper
For the piece of plastic, an ice cream bucket lid works great. Other reasonably stiff pieces of plastic will work too, but make sure you don't use one that's too stiff or it might damage the spokes on your bike. I couldn't find an ice cream lid when I started making this instructable, so I used two bendier sour cream lids (I later found an ice cream lid, that's what the yellow ones are from).
Get the piece of plastic, and cut out a piece about four inches long by one inch wide. You can make multiple ones too, it might make it louder (I've never used more than one at once though).
Step 2: Attach Flapper to Bike
Ok, now you need your bike. Place the flapper on the rear forks (you can put it on the front forks, but the engine on a bike is more at the back), with one end wrapped around it a bit, and the other pointing right in to the wheel. Make sure you put it on the side where the gears aren't. Before taping it down, you should spin the wheel to make sure it hits the spokes. This is what will make the sound.
There's a bunch of pictures for this step, look at them for detailed instructions on taping down the piece of plastic.
I made a mistake when doing this. Make sure the piece of plastic is pointing much more downwards, not up like it is in the pictures. Otherwise it will make a really gay high pitched sound because it is snapping back too much and hitting the spokes.
We have a be nice policy.
