My cateye MC100W does not register anything in odometer, all other functions are ok

There is a small black sensor located on the bike frame immediately next to a wheel and a magnetic device clamped to a wheel spoke. They must be lined up close together. The magnet on the spoke sends a signal to the sensor as the wheel spins. The sensor counts the number of times the wheel is rotating.

I had this problem as well. What I found was that the transmitter path from the magnetic sensor to the computer is very narrow, a 15 degree cone. Reposition your computer to fall within this cone. It should pick up the signal.

You want to make sure the magnet on the front wheel is being picked by the receiver on the fork. Sometimes that magnet attached to the spoke will move on the spoke so that it no longer closely passes by the receiver. If the magnet has been lost, check with you can check with your local bike shop for an extra.

I have set the computer up, i think but its not registering when i ride my bike. Am i missing something or not set it up correctly the batteries are fine in both parts? can somebody help

If it's mounted correctly the display will indicate a speed whenever you rotate the wheel with the sensor and magnet on it. The magnet needs to pass within about 2-3 mm of the sensor.

I just installed a brand new Kettler ergometer axiom p2

If this is a bicycle computer you're talking about there's a little magnet that has to be installed on the spokes of the wheel. It passes within 1 millimetre of a receiver which should be placed on the bicycle forks. Everytime the wheel turns the magnet passes a signal through the receiver to the computer which operates the computer. If the magnet is not tight enough it will turn away from the receiver and will not work. If it passes more than 1 mm from the receiver it won't work.

Where is the correct spot to put the magnet on the spoke for the v12 mini

The only placement requirement for the magnet is that it pass exactly next to the sending unit you mount on the fork (there is usually a mark on the unit). So, really the placement of the sending unit determines the "correct" placement of the magnet on the spoke.

Where do I install the magnet cadence on my bike, the picture on the manual is not helpful. I have Cateye computer. Thanks for your help ~Ann

Hi there,
The sensor should be on one of the forks.
The magnet is attached to the spokes.
They should be positioned so that as the tire rotates, the magnet passes the sensor as close as possible without actually hitting it.
Zip ties and duct tape help with the minor adjustments and to keep wiring from getting rapped.
Have fun Mike

Bicycle computer won't register speed

You don't mention the brand and model. Is this a wired or wireless computer? Strong batteries, line of sight between the unit and the sensor and a maximum distance is specified for wireless ones.

Take a magnet and manually wave it past the pickup on the fork while watching the computer. If it doesn't sense the pulses it might have a broken wire (if wired) or be too far away or have weak batteries (if wireless).

You have to have the magnet on the wheel VERY close to the sensor on the fork leg. Also play around with moving the sensor up and down the fork leg, all the while keeping the magnet VERY close to the sensor.

On both the sensor stick (which goes on the fork) and the magnet (which goes on the spokes) there is a center line engraved on each. The centerlines on both have to cross each other at a distance of about 1/4" to register on the odometer.

You can use almost any magnet with a speed sensor because they all 'register' a loop of the wheel with a magnet field sensor. The magnet must be no more than 8mm from the sensor to register the field. IF it is an older magnet, you might need to get it closer to the sensor. I always touch them, then move one or the other away just enough so they don't bump. Works every time. :)
