The best simple-old tyme "DUMB COMPUTER"-WIRELESS Speedometer in my opinion is the INBIKE IC-321.
"DUMB" in this context means that there is no UPLOAD/DOWNLOAD...whatever you wanna call that...... It Simply is "DUMB" like the best cateyes from 1982, except better.
Why better?
......LARGER EASIER TO READ DISPLAY.......two CR-2032 button cell batteries(one in sensor, and one in head unit).....
........ODOMETER at top right/CLOCK at top left/SPEEDOMETER is center & large and EASY TO SEE............
..............Here is the OWNERS MANUAL for the INBIKE IC-321:

.........Here are two different random, highly rated, USA based, Ebay vendors who carry the INBIKE IC-321 WIRELESS in both the White display or Green display
THERE ARE PROBABLY MANY OTHER VENDORS on Ebay both USA & China based who may carry the INBIKE IC-321 WIRELESS for perhaps less.
***YOU WILL NEED TO SEARCH Ebay & Amazon, etc to DETERMINE WHAT VENDOR HAS THE BEST PRICING***
....suggest that you SEARCH Ebay all categories for: inbike speedometer
