    I just got the above bike computer and ride a Mezzo with 16 inch wheels but when it comes to choosing the tyre circumferance there is no exact match to those listed with the instruction sheet that came with it.

    The Mezzo tyre is 16 * 1 /3/8 . but I don't know what that is in cm which is what the Cat Eye measures in. Does anyone know what cm I should enter in the computer ? The Mezzo tyre is the same size and a Brompton ...

    Easiest thing to do is get a measuring tape , and chalk/ pencil . Put a line mark on the floor . Bring your front wheel valve in line with the mark on the floor ( bottom of rim ) . Then , simply roll your bike forward until the valve is at the bottom again ( i.e. one complete revolution of the wheel ) and put a 2nd mark on the floor . Measure the distance between the marks and put this into your computer . Incidentally , the measurement will probably be in mm not cm , I know my Cateye measurement is in mm ( in my case my racing wheel is 2113mm, that's the value I entered into my bike computer).
