cadence vs km/hr

cat-i now just imagine how pretty the picture can be with actual cadence and speed squiggled all over the 'prettier' picture you just painted

its not that hard' date=' since you need to convert from km/h to rev/min. Firstly you'll need the radius from the BB to where you'll attach the magnet. Then multiply by two PI to get circumference. This you will need to input into your cpu, as if it was your wheel's circumference. you now have the distance of one revolutions.  You now have rev/h. Now just divide by 60 to get rev/min. Only used logic here, so theoretically it should work

why would you need the radius? <confused?>

 

you'd need a bit of maths to get from km/h to rev/h, no?

 

won't it be easier to just set the circumference to a easlily-convertable number like 100 (or whatever 'easy' number the cyclometer would allow) ?

 

 

Hmmm... well i figured you'd attach it by the crank, but i guess that's not really necessary.
