      No, unfortunately not, as right now there isn’t a way to convert the accelerometer to measure distance because there isn’t a translation of resistance (wattage) that would otherwise impact speed.

      If the radius of the wheel is entered into some equation like Diameter X (pie) and that was applied to the RPM. Couldn’t they get a speed and a distance?

    Would it be possible to use the RPM on the wheel for measuring distance instead of cadence?

      Hmm, that’d be interesting on the wheel itself. In that case though, it’d see that as a ‘rotation’ like cadence, rather than a ‘pass’ like a wheel magnet. I suspect however that Wahoo could actually program the unit to understand wheel rotations instead and then change around the spec to assume a given wheel circumference and thus a given speed (and thereby distance).

    I inadvertently left my garmin footpod on and inadvertently went on my MTB and inadvertently had my watch set to run mode. Sure enough up came cadence, it was wrong though.

    Same principle on any bike I guess.

      HI guys. Using some kind of pod during my spinning sessions was my idea as well.
      Why would the footpod yield inaccurate results if used on a bike?
      Is it because its sensitivity needs to be tweaked in order to better process the circular motion of the leg?

    There is a possibility to use also adidas ant+ SPEED_CELL for cycling cadence.

    The adidas ant+ SPEED_CELL can also measure cadence, but only if you use it with the miCoach mobile app for iphone, and have chosen “cycling” as the activity.

      It supports BT power meters. It was the first app to do so. Largely, because Wahoo developed the first BT power meter – both in a trainer as the Kinetic inRide, and then in a on-bike unit, as Stages cycling. They did all the under the hood work on the BT side of the equation and the apps.

      Correct, at this time the Wahoo RPM doesn’t transmit ANT+ (which is what the Garmin unit understands). Now, Wahoo has stated that they expect to update/make all sensors dual ANT+/Bluetooth Smart by the end of the year, so, I’d assume this would fall in that same camp as well.

      If you have a Garmin strap, you’ll need the ANT+ adapter from Wahoo Fitness – which works on a hundred or two hundred applications today (Strava/MapMyFitness/billion more).

      On the Polar straps, if you have a Polar H6/H7, then those are Bluetooth Smart, and would work with an iPhone 4s or later. Otherwise, no, no way to get the Polar straps onto your unit.

      If you have neither, then you can pickup any Bluetooth Smart strap (doesn’t have to be Wahoo). Of note is the 4iiii’s Viiiiva strap, which does both Bluetooth Smart and ANT+ (so Garmin) at the same time, so you can use it for both. Wahoo has a similar strap coming out in a few months.

      I would say mainly for post-exercise analyzing. As you ride you’ll feel the cadence, but it is interesting afterwards to see how your cadence, watts and pulse correlates. Eg. you’re riding a hill, and want’s to compare your rides; given the same pulse and cadence, does your speed/power increase?

    I can confirm that this trick works with the Adidas BLE footpod speed cell on an exercise bike. I tried it on an elliptical, but it doesn’t appear to work reliably.

    And it’s too easy to loose the footpad, by the way. That rubber sleeve trick is key.

    Hi Ray,
    looking at post 14, I still wonder if I understood well. Using the Garmin Footpod in the same way you used the Wahoo Pod and connected to my FR310XT will have the same result (cadence) as the Wahoo Pod linked to a BT device, or not? Isn’t t the Technik of both pods quite similar??

      No, you can’t use it in the same way – been there, tried that. It’s not designed to measure in that orientation and/or type of cadence. No doubt Dynastream could likely easily re-program it do measure that, but definitely not for existing units.

    Interesting — and maybe I will try this. Like others, I am wanting distance, which is more important based on my level of training. I have the FR310 and love that I can wear it on treadmill (via footpod) and use the heart rate monitor on spin bike — but then when connecting to garmin connect, I have to manuall input my distance, based on my bike monitor stats.And, sometimes I jump off the bike, and get side tracked and hours later when I connect to GC, oops — my bike screen has turned off — was that 7 miles today? 8, 5, 10?

    So, looking for better solution — would LOVE to know of one. My treadmill and spin bike (le tour de france) both come with the IFIT website application, but I have stopped using that — while cool at first, if I run outside, or do a cardio class or other activity, it doesn’t show all activity, where as when using my FR310, all my acitivity is pushed to GC, and even though there is some need for manual input — at least my activity and HR is captured.

    To others that might be interested, I found the following while searching for a Garmin FR option on spinner, it won’t work for me since the LTDF has a back spin wheel — not front spin wheel — but found this quite creative:

I don’t really need to record RPM, as that only guides my spin cadence while the 910XT guides my %HRmax effort.

    I have been using the Wahoo RPM as mentioned in the post for my last couple spin classes. I put it vertically in my sock. I find that the data jumps all over the place, especially when I get into ‘climbs’ where my cadence may drop down closer to 60 RPM (for example jumping rapidly between 15 and 60 RPM while I know I am maintaining a steady pace).

    Have you tried it since your original post and run into any of these issues? Do I possibly have the sensor setup incorrectly (I just linked it using the new Add Sensor functionality in the updated app)?

    Reply

    • Rainmaker
      April 30, 2014

      I could see it jumping temporarily when you change into climbing position (due to accelerometer shifts). The other question is how ‘snug’ it is. Any loose-ness at all will definitely affect it.

      I haven’t played with it too much in a spin scenario since then. I have started using it outdoors on a bike, but only casually (not yet doing detailed comparison tests).

    First of all a BIG „Thank You“ to Wahoo who send me the newest version V2 of the sensor which supports Bluetooth LE and ANT+ similar. And also again a „Thank You” to DCR for this great Idea.

    Meanwhile I tried the Cadence-Sensor with three different Spinning bikes and everything works fine. Sometimes the signal is a bit delayed (2-3s), but this is just in case of a huge change of the cadence. I fixed the senor on my training shoe so all I have to do is to step into the pedal and start Spinning.

    I use the sensor together with the iCardio-App(Digifit) and it’s a perfect solution for Spinning. It’s a good motivation to see, how effective you train and to set a goal during the workout.

    For me Spinning makes much more fun now.

    It’d be pretty slick if they would make a special indoor training panel in the fitness app for if you just have cadence and time, you could input the distance traveled (obtainable from many stationary bikes) and then it could calculate average mph, and for those of us that also sync with fitness pal things like calories burned, etc.

    DC Rainmaker you commented in your blog that you discovered the Wahoo sensor can be fitted in your shoe. However, I looked at the Wahoo website and saw this:

    Using the Shoe Clip Mount
    1.Take the clip provided and lock in the RPM by sliding it in horizontally and then twisting it vertically into place.
    2.Place on your shoe by threading the velcro strap through the space in the back of the clip.
    3.Make sure the sensor is your shoe vertically with either the “w” or “o” facing you. If it is horizontal with all letters facing you, it will not be able to capture data.
    6.Pair the RPM to the Wahoo Fitness App.

    So it seems that this was already available. Great way to measure your cadence on a spin bike and with you HR this will give you a lot of data.

Please let me know if you’ve had any success and how you did your setup on indoor spinning cycles vs. outdoor bikes setup for indoor spinning. Thanks!

      I haven’t tried it in my sock. Keep meaning to do that. The challenge is that’s a slightly different rotation than on the crank arm (as it stays level).

      I’d be interested to hear if this works. I have been using the keiser bikes at my local Y with my Fenix 3 in indoor bike mode with the HRM. If it is your bike, you could just use the new style cadence that attaches to the pedal.

      Just a quick follow-up for all of You, who consider using Garmin cadence sensor on a gym or spin bike.
      I’ve tried attaching it to a shoe in many different ways and unfortunately it doesn’t work (I can pair the sensor, but it shows 0 all the time). Actually it seems it requires full 360deg rotation to work properly (movement like on a crank). Sole position change (with orientation unchanged) is not sufficient for it to work :(

      I have used the Garmin Cadence Sensor (Part Number: 010-12104-00) attached to a zoot ankle strap, which I have then strapped to the crank arm of a spin bike. I have done this on many occasions in different locations, but my test case was at Flywheel, where they have a built-in report on their “RPMs” (it’s not real RPMs, but they keep a constant metric re: rotations/minute). This system reported consistent RPMs, and it stayed true on a relative basis to the Flywheel RPM reports.

      I connected the Sensor to my Suunto Ambit 2S. It worked very well for me.

      It does take a little work to secure the unit to the zoot band – I threaded the band through the silicone/rubber bands that attach to the Cadence sensor.

      I also almost forgot the unit on a bike, leaving it at a gym for 48 hours, once. However, no one touched it and it was there when I returned. I have walked out of classes without taking the sensor a couple of times, too. However, I still have the unit and I really like it.

    “You’ll need some phone that supports Bluetooth Smart devices. That could be … any Android 4.3 phone.” – am I right to say that’s wrong? Bluetooth Smart is only possible with Android 4.3 or higher, however only a minority of phones with Android 4.3 or higher actually support Bluetooth Smart – yes?

      Actually, the Android 4.3 base OS supports Bluetooth Smart. And, there’s pretty much no phone out there that supports Android 4.3 that doesn’t have the hardware for BT smart.

      Where you instead sometimes run into issues is at the app layer itself, due to various incompatibilities there.

    It looks like this now comes in an Ant+ variant. If I get this to pair with my Garmin, it isn’t treated as a foot pod is it? In other words, if I have a foot pod for running and the Wahoo RPM for spinning there is no re-pairing required when switching between the activities?

    Thanks!

      Indeed, the Wahoo RPMv2 is now dual ANT+/BLE.

      However note that it sends as a cycling cadence sensor – and not a running sensor so it’s technically a different ANT+ profile and won’t be picked up running-wise.

      So in this case, if you have a Garmin multisport watch, they’re treated as two separate sensors – but they don’t overwrite each other. So you won’t have to re-pair.

    Hi, is it right now possible, that you get cadence from wahoo RPM and speed (from the GPS V800) into the v800?
    Or is it still an 0 km/h from the v800 ?

    I have been using the Wahoo Tickr X Heart Rate Strap, which does measure bike cadence, on an indoor trainer for months. Works just fine in the Wahoo Fitness App. Pretty neat! One item, the heart rate strap, does HR and the cadence. Nothing to put in or on the shoe.

    Have you ever thought about how to get power at a reasonable price out of a spin bike?

    I have been using my garmin bike computer and cadence sensor with HR for a while now, but always wonder if there is a way of getting it to read power. With all these new power meters coming out, something like the 4iiis should theoretically work if cranks are aluminium.

      I have also been using a powercal as some sort of metric gathering system, using it in conjunction to a garmin cadence sensor on a zoot ankle strap (as discussed above). It is not the same as being on an outdoor bike, of course.

      However, I do get some good, useful data while having the ability to train on the road, in a variety of gyms, on various bikes, etc… I wish I could train outside, or on a single trainer, but this is a solid option that I use to live my life and train a bit, too.

    Can you expand on using this method with the Polar v800? I am not completely clear.

    I have never used anything beyond a heart rate monitor for workouts and I am looking to kick up my training / analyze my data for indoor gym bike & road bike workouts.

    I was hoping your method could give me data similar to the Expresso bike at the gym (it’s great but I am sick of all of the rides) on both the gym bike and my road bike.

    I plan to use the Polar v800 for kayaking and weight lifting too.

    Thanks for any insight.

    Kim, I personally do not outdoor cycling but I do a lot of indoor cycling, about 2-3 times a week. I paired the wahoo rpm cadence sensor to my v800 and it basically does what the name says…it measures your cadence. You can then multiply that conduct a simple formula to find your km/hr and by default how many km you rode that session using this website link to endmemo.com

    I also have paired a Scosche Rhythm Plus to my v800 for my aerobic classes and of course the Polar H7 and the Stride Sensor for my outdoor runs/ treadmill. I love my v800 and I have had it since March of this year with absolutely ZERO issues. I ran my first 10K with it and I am now training for my first half marathon. I came across a group Fans of Polar V800 group on Facebook and you will see all sorts of tips for your v800.

    Hi there!

    Would it be possible to use my Polar V800 to register cadence by using Wahoo RPM while registering heart rates with my Polar H7 band? If I’m correct, this will mean sending data from two different devices at the same time using Bluetooth connection.
    I guess the answer is yes as I receive information from Polar Cadence sensor and heartrate at the same time while on my road bike.
    Moreover, is there a way to export data from Wahoo App to Polar Flow? or to have data from Wahoo RPM directly recorded in Polar Flow or Polar Beat? Or I just need to use my Polar V800 to register the training session and then sync with Flow, isnt’ it?
    Best regardes, great idea, great review!

      Yes, you can do both to the same device (but you can’t have one sensor sending to two devices, such as also to the Wahoo App or Polar App at the same time).

    Would this be the best option for tracking info (time/speed/distance/cadence) on a spin bike you own that doesn’t have any built in ANT+ capabilities?

    Do you know of any standard bike computers that have sensors able to be attached to the wheel of a spin/stationary bike instead of a spoke on a normal bike? Or is either this or attaching a speed/cadence sensor the best option? Thanks!

    I want to implement your solution for cadence monitoring on my bike trainer, gym, and hotel bikes right away. My desire is to have a richer set of data on each ride beyond average cadence and peak cadence. There is so much more of a story to tell. Your description here should get me to step 2 very nicely. Ultimately I want continual data on cadence and pulse that can be further analyzed. Thank you for this post.

      I came across a good thread on the Garmin forum (link to forums.garmin.com) that mentions a conflict between Ant+ and Bluetooth, when both are running simultaneously. I disabled Bluetooth on my phone, while using the RPM & Garmin, and no more dropouts. It’s all good now!

    I have been thinking of a way to use TrainerRoad on our old Saris/CycleOps indoor trainer. Bought a Wahoo speed/cadence sensor but the cadence part won’t work because of the way the trainer wheel is offset. So – thinking now about buying the cadence sensor, putting it in my sock, using the speed part of the speed/cadence sensor and avoiding the $500 bill from CycleOps. Think that would work for TR? My wife doesn’t want to put her road bike on a Snap or I would just buy that.

    Hello Everyone, long time since I came on this topic, good to see it is still alive. When I first started running, I use to use the Nike + with my iPod nano and the Nike Sensor. I wanted to use it on several shoes so I purchased an after market holder, came in a pack of 3. As a proud user of the Polar v800, I no longer use the Nike app or sensor. However just for fun one day a few months ago, I tried to put the Wahoo RPM sensor in the after market holder and it fit perfectly. Here is the link to the image on ebay, don’t know if it is available in Amazon. link to ebay.com

    At work we have a old spinning bike Livestrong LS9.09IC (now called Tomahawk 9.9IC) with Ant+ Bike computer, and i can confirm that the Speed Sensor Pairs with Garmin 235, and it shows Distance, Max speed, speed, average Etc etc, so now i don’t have to add my distance manually to Garmin Connect.
