Installing Der Bike Computer 500.
Back when I was a kid we just hooked up a speedometer/odometer to the front tire and we were all set.

These days you have to program a computer.

Here's a tip if you get the Sigma Sport BC 500 Bike Computer
:

When you get to wheel size, read the number on the side of the tire.

My numbers are 26 x 2.125 which corresponds to a setting 1325 in the WS mph setting!

I installed the whole thing on my bike and then it started to thunder.

But I hadn't tried out the new bike computer.

So I took the bike for a spin, risking life and limb, and the bike computer registered 0.00 MPH.

Oh Oh.

Something's wrong.

I just watched the installation video and it conflicts with the installation manual. The video shows the sensor farther down the spokes. I'll have to change that.

Update:
I moved the sensor down lower and everything seems to be working fine. I'll take the bike out for a spin tomorrow to confirm.

Right now I need to send an email to Sigma Sport in Germany to tell them that their installation manual is wrong.

Update:
Here the response I got from Sigma Sport:

It can be mounted anywhere on the spoke & fork as long as it is 1/4" or less from the magnet to the transmitter.
