    VDO wireless computer works great for stoker

    I purchased a VDO C2DS wireless cyclecomputer this weekend becaused it claimed 1.5 meter range. My thinking was it should be great for the stoker, which would be at the typical limit of 0.7 meter range of other brands. The VDO uses digital encoding instead of analog over the RF link between transmitter and computer.

    Worked great! Reliable speed reading with stoker on the tandem.

    I installed the transmitter/sensor near the rear brake, the two cable ties provided worked fine. The sensor magnet is near the rim, but is very small, so no problems mounting. The computer was installed on the stoker's handlebars.

    I use an Shimano flightdeck for the captain and didn't have any interference between the two wireless systems.

    The VDO C2DS was on sale at Performance Bike for $50. They also make three other wireless models that use the same digital wireless technology.

    Yes the DS series VDO computers do have a very long range, I use 2 VDO C3 DS computers off one transmitter which is mounted in the front fork and works great.
    It may not be fancy but it gets me were I need to go.

    We are looking for a wireless speedo for the stoker as well. I noticed on the Performance website that the C2DS & C3DS (I think) show cadence as an "option". The C4DS (about $90) has cadence.

    If we want cadence, should I just go ahead & get the $90 model?

    My stoker is familiar with the Cateye interface. Is the VDO similar or easy to figure out (some aren't very user friendly)?

    Also, with the VDO - is it possible to key in our present mileage (so we're not starting at zero)?

    The C3 DS at Performance is with cadence these are the units I use.
    Its best to get it with the cadence unit if you buy it separately its around $40.
    You can preset mileage into the VDO computer.

    Yes, the VDO interface is user friendly. I have a Cateye on my mtn. bike and think the VDO is much better. You can read the user manual before you buy at www.vdocyclecomputing.com.

    Yes, can preset the mileage.

    As we are buying new computers for our new tandem I wrote Ibex Sports who seems to be the USA supplier for VDO. In chatting with Steve he informed me the C1SD, C2SD, C3SD and C4SD now come with (are you ready for this?) a 5 meter range (not a typo-that is around 16 feet). That is well, well within the range of the stoker bar (but then the old range of 1.5 meter was too). What's more, you can code any combination of DS computer heads to read off of one transmitter.

    Old stock is out there so if if you happen to need the longer range for your octo-tandem <grin> be sure to get the new stock.

    By the way, they have not updated their user manual at vdocyclecomputing.com for the DS series cyclometers so it still lists the 1.5 meter range.

    Yes I have tested mine and can spin my wheel and walk away with the computer in hand a good 5-6 ft away and still get signal which is more than enough distance. I will test to see what the max is just out of curiosity, I also have 2 computers synced up to one transmitter and works great, I also use one of the computers on my commuter using the 2nd bike settings.

    I just bought a VDO C3DS. I was trying to get it set up for the tandem last night. I am familiar with the Cateye user interface. The VDO has a lot more function but doesn't seem to be as intuitive.

    With the Cateye, it displays current speed along with one of: avg speed, cadence, distance, odometer, time, max speed or elapsed time. You reset any of those by simultaneously pressing both buttons.

    With the VDO, it displays the current speed with one of many other functions. How do I reset tripdistance, max speed & elapsed time? It seems like the "C" button does nothing.

    When you see Tripdistance Settings on screen press M (right button) Using the middle button scroll till you see Data Reset press M button 3 times you will see Reset Done.
    You can also go to Navigator Select press M button scroll middle button down 1 time to Navigator Reset press M 3 times reset done.
    This will zero out everything but your total mileage and bike 1 & 2 mileage will remain and will not reset.

    NOTE: To my above post on testing how far I could get from the sender I was able to to get 10 ft away before dropping signal with the VDO C3 DS transmitter.
