Bonniksen Veteran Vintage Motorcycle Speedometer

This Video shows the operation of a Bonniksen Isochronous Speedometer designed by Bahne Bonniksen a Danish Horologist who was also famous for inventing the Carousel Movement for Pocket Watches. Later he sold the Patent to Rotherhams of Coventry who continued to make these Speedometers till the mid 30's

This is more than just a speedometer. This is an exquisite work of art.

I have one on my 1930 Scott Flying Squirrel. It’s a work of genius!

It's a speedometer that shows what speed you were doing, even when you're stopped. What a terrific idea! 🙄We had one for years out in the garden shed - not sure what happened to it... It's possible it would've been worth a fortune by now.

Yes you are right they are becoming valuable now. The heads alone are worth between 600 & 1000 Pounds without being restored. You Have to be careful not to be distracted by the needles whilst you are riding.

Very nice video and very interesting. Thanks for sharing. I came here after watching the Audrain video where Mr. Leno mentions it, and they used a clip from this video. Cheers.
