Crivit Bike Computer from Lidl

Restless

I bought a bike computer from Lidl but lost the instructions on how to install it.
The model is a 43489. Am just wondering can anyone help me there.
There are two settings during setup called c1 and c2. What do these reference?

These are the tyre circumference measurements and must be correct for the computer to accurately measure speed and distance. Most computers support 2 separate bikes and hence there are two settings. If you only have one bike you can just set one or set both to the same value.

A list of values for different tyre sizes is given here. Most computers use Group F values (the distance travelled in one full wheel revolution in millimetres).

thanks Paul. having the two settings completely threw me. Will try it now.

Got one of these bike computers recently and I'm wondering about setting the wheel size.
There was a measurement guide in the instructions but I just measured the circumference myself.
Well this be accurate ?

I fitted one to my sons bike last weekend. Measuring the circumference would be the most accurate ok. I did it the other way, measuring the diameter and multiplying it by 3.1416.

Lads, the only round shape these should be on/in is a bin.

They are even a poor clock.
