To calculate the overall star rating and percentage breakdown by star, we do not use a simple average. Instead, our system considers things like how recent a review is and if the reviewer bought the item on Amazon. It also analyses reviews to verify trustworthiness.
Was very simple to connect to the computer and attach on my front wheel and crack arm. The instructions in the easy start guide helped me do that. Now i'm just waiting to see when the battery goes flat and hopefully it'll be easy to change batteries too.
I bought this specifically to use with my Sunny Bike & Peloton Digital app. I didn’t realize how much the Peloton app relies on Cadence. This sensor makes the workout .. without it, you really can’t use the Peleton app. You can now connect to the Wahoo sensor directly from your Peleton workout on the app & it shows the Candence right on the Peloton app screen. A lot of the reviews say that you can’t, but Peloton updated it to connect to the wahoo sensor via Bluetooth,
Well it’s works well, connected to Wahoo ELEMNT straight away. Clearance is tight though, I didn’t want to use the tape to hold it in place (prefer the silicone holder and zip ties) but I had no choice in the end.
Thought I'd get myself a cadence meter - purely for experimentation, as I've never bothered about actually measuring/tracking my cadence before especially while actually out on my bike.
After reading around (and being tempted to go for a power meter instead) it came down to a cheap "own brand" (because why spend lots on an experiment), a Polar device (would match all my other devices but non-replaceable battery made it look a bit pricey) or this Wahoo device.
The price seemed reasonable enough with not much discount available anywhere and with the option to fit onto the Velcro strap on my shoes it seemed worth a try as I could also use it on my MTB or my occasional winter use indoor training bike and get my money's worth.
Fitting to a bike or using the shoe mount is simplicity as is setup/pairing. I've only used the shoe mount as the crank mounting options of tape or cable ties was a bit permanent while I experimented & decided but it's not rocket science.
To activate, you move/shake it and it links with your paired device and after a few revolutions it registers on the display.
Accuracy seemed good and I got to grips with it. After 3-4 days my Polar V650 suggested the battery was down to 50% - and although the Polar is sometimes a bit pessimistic about this figure with my HR monitor it seems to be a reasonable indicator that a battery has been in use for some time. I had an episode of it not registering and one of it stopping mid-ride so I figured maybe a dud battery. I changed the "no name" battery for an Energizer one and all was well for a week then another low battery warning, a failed connection and a mid-ride stop (when I stopped for a quick break) in past 24hrs. All of my rides have been about 35-40 minutes commuting - so nothing I'd say is excessive.
Changing the battery (a CR2032) involves twisting the unit out of it's mount (of necessity, quite a tight fit) and prising the case apart. Despite starting with a perfectly sized flathead screwdriver it took some cursing with various sized screwdriver blades, coins and knives to change 2 batteries in under 2 weeks and I've mangled the case in the process. Yes, it's a securely closed unit.
I'll persist with another Energiser or Duracell CR2032 but on the strength of the past 2 weeks, 12-months between battery changes isn't going to happen anytime soon. With the connection failures & mid-ride stops, I really can't recommend this item based on my experiences.
UPDATE 5th October : after 3 weeks with no use (because I've been on holiday and not been out on road bike) I deleted it from my Polar V650 then re-paired it for a fresh start. 30% battery warning but seemed to pair OK then once I started pedalling no cadence figure showing up. No more running commentaries on it's failings.
I'm actually glad the speed sensor failed after two 45 minute turbo sessions because it allowed me to see how diabolical the build quality is. There's no doubting that before the failure I was absolutely delighted with the performance of both sensors. Easy to install and worked a dream with the Sufferfest app. I was really annoyed to find the speed sensor conked out after two short rides. I thought ok, not the end of the world, it might just be the battery. I still don't know if that's the case as I couldn't remove the cover. Despite following the instructions, all that happened was the flimsy plastic was damaged. So badly that I gave up. There's no way I'd buy these again. I've sent them back for a refund and bought Garmin instead.
Got these for my spin bike to link up to the peloton digital app. I put the cadence sensor on the pedal, the speed sensor on the flywheel, opened the peloton app and was able to connect the cadence sensor right away (they don’t offer the speed option). I also was able to add both sensors to the wahoo app very easily. I compared both readings to my current speed and cadence sensor that isn’t Bluetooth compatible (that’s why the upgrade) and both readings were very close to each other. I’d also like to add this got delivered in less that 18 hrs from the time of order - amazing!
