speedometer/odometer/timer/thingy-majig
 

Another newb question here.


I was riding just a few minutes ago and when I got home it said I did 11.69 miles in 30:36, with a top speed of 47mph. I did take the downward side of a big hill as fast as I could and then kept up with a semi half way though town. I took the whole ride at a pretty solid clip, but I find it hard to believe that after my first week of street riding (and my first week in 20 years without a cigarette) that I could pull that off.
Sooooooo… How do you calibrate the little speedometer/odometer/timer/thingy-majig to make it accurate???

no manual?

First figure out if you need to enter centimeters, milimeters,etc...

Then:
Along a straight line- driveway edge, expansion seam,etc.
1. Place a piece of tape on the ground
2. Place the valve stem in the middle of the tape, & while putting some weight on the front tire, roll it one complete time around.
3. Measure with a "standard" tape measure, & multiply by 25.4 to get measurement in mm, 2.54 for cm.
4. Enter this figure into the cyclometer.

What brand cyclometer do you have? & As asked, owners manual?

Yea, what everyone else said about the comp.

But congradulations on the quiting smoking! I just did on Christmas last year. Just remember that the first weeks is the worst and it gets easier every week. You might like to download this . It is a free counter that keeps up with how much money you have saved and how many cigs you havent smoked since you stopped. Here is what it says for me:

Thanks for the stop smoking counter. it has been a bit tough.

and no owners manual on the speedo counter thingy.
thanks for the insight on fixing that.

What brand is the computer?

If you google the type & model you can probably get a pdf of the instructions.
Once you input the correct wheel & tire size it will be much more accurate.

It's just a rinky-dink Schwinn one that came with the bike.

Tis one?
