How does a Pull-Back Toy Car work?

This video has been dubbed in over 20 languages, you can change the audio track language in the Settings menu (click the gear icon in the lower right hand corner of the video).

The Pull-Back Toy Car is an incredible piece of engineering! This is sometimes called a "Wind-Up" toy car. This videos covers the specifics of the mechanism: the motor chassis, the 5 gears, and the torsion spring. We'll talk briefly about gear ratios, gear trains, and also cover why you hear that mysterious clicking noise when it winds up enough.

The toy cars in this video were downloaded from Blend Swap and I had some help for the others.

Here is some of the gear that I use for animation:

You've just solved one of my childhood mysteries

[NuhanHidayat]

Seriously, your work deserve more attention! The animation is great, your explanation is also clear & simple 👏🏻👏🏻

[aniketrastogi]

Forget how airplanes fly, this little piece of engineering is so damn satisfying. So much attention to detail to make it work the way it should.

I thought the click was the car breaking, thats incredible

[BranchEducation]

Really great video & animation! I used to love playing with those cars as a kid! That's pretty cool where the clicking comes from. It's amazing how such in-depth design is done in such small toys.

[Boffy]

Genuinely interesting video, keep it up dude :)

I think by the end of 2019, your subscribers will reach minimum 5 million. Thanks for your great work.

[petetheweet]

Can we all just stop and appreciate how smart you need to be to understand how all these things work AND THEN to make extremely detailed 3D animations to show the inner workings? Absolutely incredible!

Car: clicks

Me: still pulling it backwards

Le me think:
If still pull, it will go more far

[argenteuseagle]

Amazing, I don't even learn this in school. A simple thing can be complicating, but you explain it clearly. Keep up the good work!

I’m turning 30 this year. And i just found out what is causing that clicking sound! What a great joy 😂 thank you sir for this video. This made my day. Your work is greatly appreciated!

[candidmoe]

It's impressive how much ingenuity in that little motor. There is a lot of requirements solved with great economy of parts: fail save winding up, different gear ratios for moving forward/backward, auto-disconnect when spring unbound ...

Brilliant, took my sons broken toy apart yesterday, gears went all over the place, this video helped me get them all back where they should be, and now one happy boy, thanks for the description and explanation - this is what the internet should be for!!

If only toy manufacturers could actually make better quality tires on these things.

[Alfred]

I can see your favourite car is Lancer Evo X.

[williamhendriks]

How do you only have 112k subs? This is some of the best animations I've ever seen!

[literallyh]

I recently disassembled a toy car to see how it worked. I couldn't for the life of me put it back together until now. I have such an appreciation for how this stuff works and for your explanation.

[crooked]

Dude i`m 30, and till this day I did not know how these cars work. Thanks man ! Great job.

Toy car: *click click click click click*
Me: *still pull the car back*
