maybe i need to replace the battery.

i'll try that next.

On my bike, the magnetic one doesnt even need to touch the magnet on
the spokes to read it, but when I put it on my bike, I had to set it so
it bearly clipped the magnet, then it would register.

Is yours actually hitting the magnet? is the magnet part set up right?
I had mine on the left side at first, and it didnt work, then I noticed
I had to move everything to the right.

Matt,

When you spin the tire, it should turn on automatically, or show some
MPH. My guess is that the magnet is not close enough to the sensor
mounted on the fork blade.

It should be as close as possible to the sensor without hitting it. We
are talking mm's here. Move the magnet closer to the center of the
wheel and move the sensor as well. That will move the magnet farther
outward.

Try that, and then change out the battery if it doesn't work. Moving it
to the other fork blade as earlier stated might be good to try as
well.

Mine goes to sleep if it isn't used. So, if I just turn the magnet one
time past the sensor, the display comes on and that shows me it is
working. A fast spin shows mph.

Cheers.

One question.

The magnet I use attachs to the spokes, at the point where it crosses,
go up a little, and it mounts between them.

I read the measurement on the computer should be at 2770, is that
right? Even when the magnet is set just a few inches above the axle?

It's counting revolutions. It doesn't matter where the magnet is on
the spokes. The computer setting (2770) is going to be the same no
matter where the magnet is on the spokes.

You just need to position the magnet on the spoke where it can get
close enough to the sensor. It needs to pass within a mm or two. You
may have to shim behind the sensor (where it attaches to the fork) to
get it close enough to the magnet. A couple layers of tape can work
well as a shim.

Something around 2770 or 2780 will give you a good measurement.

I believe that the sensor has a little reed switch in it. The magnet
opens (or closes) this as it goes past. That means that the switch has
to be aligned in the correct direction, as well as being the correct
distance away.

The possibilities are:

- Flat or faulty battery. Unlikely if computer is new, and if the
display is showing anything at all.
- Faulty computer. Unilkely.
- Switch (sensor) is too far from the magnet.
- Sensor is wrongly aligned with the magnet.
- Wheel/frame is twisting when you ride, and changing the distance
between the sensor and the magnet.
- You have not fully completed the set up procedure for the computer,
so it is not yet ready to read the speed.
- Break in the wire, or other poor connection.
