Let’s talk speed and the read-out giving by any bike computer attached to the wheel measuring wheel circumference, and tube size …
It’s false get real… like speedometers in cars …they measure the rate or spin of wheels..
They don’t account for bad roads, bad weather,
Bad bike handling…front wind…
Back wind etc etc etc….

The pedals turn: not just the left one but the right one too 😉

you’re promisied that if you are good and do the right things you will be rewarded later. just leads to dissapointment

Were you on illegal substances when you wrote this? Like the original post it makes no sense.

The bike wheel rolls along the road surface, the number of turns is exactly related to how far it has travelled. the front wheel does not slip against the road surface. They can be inaacurate if they are set up incorrectly with the wrong diameter used, they could arguably be wrong if tyres are changed or not inflated correctly chaging the diameter.

Air resistance and rolling resitance do not make them less accurate at measuring speed. These things can throw off power calculations, but if you want meaningful power data you need a power meter.

World record run’s happen
World record run’s happen indoor …
On a track if it’s about distance …
Without wind …on wood …
I’d use strava ..it has gps ..or connection..and it keeps track of training so …at a desktop you coul’d see data of the training. _after training”

It’ll be those new-fangled airspeed metres that pros use these days. Can’t imagine it’ll catch on…
