Air operated speedometer??

[whopperchopper]

Hi, picked up this Senko speedo, anyone have any literature or anyone running one on there bike? Only a few pics on line and one advertisement. Looks to be from 1951 and later. Thanks!

I've seen a couple different versions of bicycle pitot tubes out there. Don't know anything about yours, unfortunately. I do believe air speed is often more important to know that ground speed on an old cruiser. Pushing 50+ pounds of bike sitting upright? I'll take air speed any day.

This is one of the earlier versions I’ve seen

30’s maybe?

Here are some better pics of one of these earlier ones. Does anyone know when these were first introduced? I'd like to put one on a bike but want to know what dates would be correct. V/r Shawn

Pick one; mount and ride!
I will if you wont; hahaha.
There's only a couple of folks that would know anyway....

Late 20’s early 30’s.
More of a late Motorbike era accessory.
(For the record, this statement is wrong. Read further for correct era documentation.)
