I have an easy go race. I want to make sure my display computer is set properly. On the specs for the bike it says my tire size is 700x 28c. The display says 26 for the wheels. Is this correct? I've heard on a you tube reveiw for the bike it should be set on 28. I just want to make sure I have an accurate distance reading when I ride. Thanks in advance for any response that would help me.
Correct wheel size for computer?

There should be additional settings. 28 isn't correct. I just programmed a Cat Eye for a fellow yesterday and it had options for 700C which is closer to 29?

To grt it right, you'd have to actually cross reference with another device, like GPS or Google maps measuring tool. See my posts here: https://electricbikereview.com/forums/threads/em-street-display-not-accurate-for-mileage.4404/
To really get it right put a mark the top of the tire with chalk or paint that will leave a mark when you push the bike forward (your weight on the bike) so the tire rotates one full turn and puts 2 marks on the ground. Measure the distance between the 2 spots. Convert to metric and enter the number for tire size. that is the ONLY way to get a truly accurate speed and distance setting. The general numbers used for a given wheel size can be way off. How much air you have in the tires makes a difference. Even your body weight changes it.
