Question by Pedro P: What is by bicycle wheel size?
I changed my batteries and now I need to enter the bicycle size again.
The computer shows a four digit number and I do not know what to enter, my bicycle wheel size is 28′
I searched for the calculations but I cannot find it.

Put in 700c and that should probably make it work.

Probably 28/1 and 1/4 or 28/ 1.250. 1,25 is 4 digits
Use the chart on the link below. I have several bikes and a cyclocomputer for each one. I wrote down the wheel size on a label and put it on the back of the computer and on the computer mount so I know which ones belong to what bike. It also comes in handy when you need to change batteries.

I would wager to say your tire size is NOT 28″. Most likely a 700C tire of some dimension…700 x 28C or 700 x 35c for example. LOOK on the sidewall of the tire. You don’t have the instructions? If lost or accidentally thrown out – see link below.

It’s a loooong list. You’ll need to match it up to one listed. Good luck.

to get it right, do a new Y/A question with the tire size 28 X ??? … I will look it up for you!

Are you sure that your wheel is 28″? Today, that is a very rare size. Most road bikes use 700c wheels which are a very different size. Look at the size stamped on the rubber sidewall of your tires, that is the size of your wheel, and you can look up the average circumference of that size tire, or measure it yourself
