    wireless vs wired

    Im interested in getting a bike computer and am looking at both wired and wireless. Sure the wireless is neater and more expensive, but is that the only draw back? Is there any lack of signal response or lack of sensor accuracy? I assume the wired system would be more accurate because of the direct connection but does the wireless have room for error?

    I have not noticed any loss of accuracy after switching to wireless. It does stop receiving a signal when near some strong electromagnetic fields, though (still, no trouble with power lines or such - the places where mine blanks out do not have any visible sources of interference). I hear some wireless computers can correct for this, though, and fill in the gap using your average speed, which should be accurate enough.

    Cold weather can be an issue, because of all the batteries. You can always take the computer with you and keep it in your pocket, but the rest of the wireless setup stays out with the bike. If it's really cold, it'll kill the batteries in no time. This was one of the reasons why I went back to wired.

    I have had zero issues with my $20 "ascent" brand wireless computers, on 2 bikes. No issues with LED light interference either.

    I own 3 wired units, no wireless, the wired units work so good I don't have need for wireless, unless they are cheaper.

    I have a CatEye wireless and the equivalent wired model. Both bottom of the line CatEyes. The wireless annoys me by showing impossible maximum speeds.

    Also, don't get the CatEye Velos because they don't have average speed. I don't know why I overlooked this when searching for an inexpensive and reliable cyclocomputer.

    I like both computers beyond the wireless interference I have received. I bought a third cyclocomputer and it's wired. I'm not sure I will go back to wireless.

    I've been thinking about getting one, too, so I asked my bike mechanic about them. He claims the wireless ones go through a lot more batteries. Is that true?

    The wireless ones have more batteries, so in that sense yes. In addition to the battery in your computer, there's a battery down in the magnet sensor, where the signal is sent. Some manufacturers add yet another battery in the computer handlebar mount, where the signal is received.

    How often do you find you have to change them?

    I've had greater reliability with the wireless. Wired systems suck in the rain when the contacts get wet and short out (cough, last week's 300k, cough).

    When I was still using wireless, keeping the bike out one night in -10 to -20C pretty much killed the batteries. Bringing them inside for a while before next ride revived them somewhat, but after a couple of nights nothing really helped. Wired LCD screen goes blank too after some time in such temperatures, but it logs the information nevertheless. Wireless was utterly and completely dead.

    The storage room I have for bikes is a bit warmer, say above 0C at all times, so that was way better. But there's no way to stop the batteries being exposed to cold when riding, so it became too much of a hassle in any case.

    I only had the wireless setup for one summer, and during that time I never had to change batteries. Problems started with winter.

    I bought a wireless and it has limitations that the sensor is not to exceed 24" away from the main unit. I lost interest on that one and instead bought a wired unit which I find to be more accurate and worry free.
    On wireless, you can get interferance and may not transmit signals now and then. I'll go with the wired computer again for my next bike.

    Which wireless computer has reasonable distance for a stoker position on a tandem? I bought a cateye unit and it's only good for 70cm and that's unobstructed. I don't want to run a wire the whole way to the back wheel. I need a solid meter or so and it should pass through my wife...

    Maybe GPS? Or a Suunto HRM wristwatch. They have the BikePod transmitter for some of their HRM models that they claim has a transmission range of "max 10 meters". See http://www.suunto.fi for details.

    Do you happen to know if they have a web page in English? My Finnish is a little rusty.

    Sorry about that, posted the local site, they have an all-English global site as well.

    It seems at least their models t3, t4 and t6 can be fitted with the BikePod option.

    [edit] still wrong, grr. URL fixed now. [/edit]

    There are many threads on which computers people prefer. A search should turn up many options for you.

    Try looking at the VDO computers. The C3 DS claim and I believe from experience to transmit about 2 meters. They also don't experience a lot of the interference that others do.

    If you are a weight weenie, the batteries add grams. I have two wireless and both drive me crazy because they don't automatically start up when the wheel starts turning. I've been told that some do. Mine are newer models and were not real cheap. It maybe something to do with battery loss of always checking for a wireless signal.

    Every time we let a vehicle pass there is a little bit of compromise. But compromise allows the city to function and allows cyclists to function in the city. The trick is not to eliminate compromise but to learn how to work safely within it.
