Would This Device Slow Down A Cyclist ?

That’s really cool!
I’d actually ride my bike again.
Apparently, you don’t forget how to do such things, lol :-)

But that horsie can make the ' clipperty clop' noise all on it's own ! :~)

But it can’t sound like a motorcycle, at least I hope it can’t :-)
Did you guys put cards ( baseball cards or playing cards ) into the spokes of your bikes to simulate the motorcycle sound when you were kids? It never occurred to me that it might be an American thing :-)

Very much a thing in the UK in the 1970's , when I was young ... I don't know if it still happens today.
There was a suggestion, on a recent radio program, they should fit cards (or at least the sound effect) into electric cars !

I remember the story of adding sound to electric cars also, now that you’ve mentioned it.
As far as adding cards to the bikes, I think it’s great that it was on both sides of the pond.
Although over there you probably put them on the left side of the bike and we put them on the right, lol :-)
Also, you probably would get yelled at if, while using playing cards, you used the Queen for motorcycle sounds, lol :-)

I can't remember which side we put them in but the chain was on the right hand side of my bike.
I don't think I used playing cards - More a torn up cigarette packet - Not the soft packs you get in the US and Europe ! :~)
