Better to get a GPS cycle computer. No more setting wheel diameters! Work instantly out of the box. Can be used on ANY type of bike, actually I use mi Garmin walking , riding, running and kayaking! GPS units record GPS position (laitude & longitude) every few seconds, they also record temp, heart rate, time of day. From these recordings it calculates dozens of readings- av apeed, max speed, ect.

Most of the bicycle computers use a magnet counter to calculate the speed. One magnet is attached to the bicycle's front wheel and another one is attached to the fork. With each tire revolution, the fork magnet is triggered. The computer then can calculate the distance you traveled, your speed and more, depends on the computer's sophistication.

    Sigma wireless bicycle computer. Model BC 1606L. Wireless cadence monitor has abruptly stopped working. All other functions of this unit working perfectly. Transmitting unit and receiver have new...

    Did you throw the magnet on the crankarm? If not check the alignment of the transmitter and the magnet - sometimes they need to be quite close. Sometimes they just fail. I have seen instances where cadence worked and speed didn't and vice versa - so the unit is transmitting perfectly, but one of the sensors has gone bad.

    I took off my front tire and when i put it back on my cateye micro wireless isn't working. (it wont turn on)

    Make sure the magnet and pcikup are within the prescribed distance of each other.

    If the computer actually won't turn on (dead), change the batteries.

    Look for a manual here...

    Do you have a clock that mounts on the handle bar of a bicycle?

    I don't believe there are clocks made for bicycles. However bicycle computers show the time. They normally have several functions and you can set which ever you want to be shown. They can be bought at most bicycle shops or if you look them up in Google there's plenty of online shops selling them.

    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.

    I have an older model specialized bike computer (1998)and I can't get it to display anymore. I've replaced the battery and still nothing. There's no corrosion inside either. Any idea's?

    The screen display works when the magnet on the wheel and the sensor on the fork leg are on the same side and the the screen/ head unit is fully engaged on the mount. The magnet and sensor of the leg cannot be more than 1.5mm apart from each other..... if that doesn't fix it then your computer is just dead and it's time to get a new one!
