Wahoo RPM Speed Sensor is rated 4.0 out of 5 by 28.
Rated 1 out of 5 by from does not work This is out of the box and not working. I suspect that it was delivered with a flat battery, as was the case with my cadence sensor (see other review). But to be honest I cannot be bothered to investigate. Why? 1. I now have zero confidence in my Wahoo products after endless issues with anything I have ever bouight from them 2. I have devoted so much time to troubleshooting these products, I have lost the will carry on. I just wanna ride my bike, but all I seem to do with way too much of my precious ride time is fiddle about trying to coax some life into these substandard products (see also my review of the Reflkt +)

Rated 4 out of 5 by from where is it? I'm using this to bike. Have attached it to my shoe. Extreme easy to use, put on your shoes and off you go. You forget it is there. Other bike? No problem, still on the shoe and keeps on working. Data is sent to a Garmin 1000 and Suunto ambit at the same time. I've compared it with a garmin sensor as well. In my view, the garmin seems to give a more stable number each time, the variation of the Wahoo seems to be bigger. Don't know which one is correct butt I do have the feeling that Wahoo seems to miss so now and than a stroke, hence the reason of fluctuating more. Otherwise, very easy to pair and nothing to do when you start a ride, besides putting on your shoes.

Rated 3 out of 5 by from Did not work on first ride So, I got this setup with Wahoo fitness app on my iphone6, and went for a ride yesterday. The app pulled the speed information just fine. But it didn't seem to get any distance. I think this might be an early adopter issue, and the fix should be relatively easy - will need to contact support, and see what they say. I also had another phone in my jersey pocket, on which I had the app use gps to compare how closely the two tracked speed and distance. Will have to wait to get that comparison. The reason I want this is two fold, (1) To use with my bike on my trainer (not a wahoo trainer, nor a smart trainer) - this is assuming I can get it installed on the back hub - I currently have it on the front hub - which is what wahoo seems to recommend. (2) If I can get the route from GPS, but the speed and distance from this, I can set the GPS to only poll for data once say every 10 seconds or so, and prolong phone battery life hopefully. That way, you have the route from the GPS, but finer grain speed data. (My hope was to use this with the RFLKT+ to also get the altitude info with gps polling turned to infrequent, but I haven't gotten the RFLKT+ to work yet.)

Rated 5 out of 5 by from Excellent Product First of all I am a huge fan of all Wahoo products, so when I saw they released this I wanted to jump on it. It's super simple to pair with any ANT+ device and just works. I actually have mine mounted to my rear wheel on my mountain bike and it reaches my head unit just fine at the stem. The minimalist design is awesome and doesn't stick out at all. And blends in very well. The casing seems sturdy and the straps are tough enough to keep it in place. Well worth the money.

Rated 3 out of 5 by from Dosn't fit to dynamo hubs The sensor only comes with one rubber mountingband which is too short to fit it on any dynamo hubs (e.g. Shimano, SON, Supernova). This is very disapointing and should be pointed out in the product description. A second (longer) rubber mountingband shout be included. Any idea where i can order a suitable mountingband? Dos Whaoo offer it as a spare part?

Rated 2 out of 5 by from Connection problems I am having trouble keeping the RPM speed sensor connected to my Edge520. The sensor has been replaced and all the troubleshooting Garmin could think of has been done. Any ideas?

Rated 3 out of 5 by from Good design but has its flaws I got this setup with my Ciclo bike computer using Ant+, it works fine but there's is at least like a 5 second delay to the reading. I then also paired it with my iPhone using Bluetooth and it has the same delay. I hope a software update will fix that in the future. Otherwise, it works.

Rated 1 out of 5 by from Probably causing my Elemnt to go haywire When using this with my Elemnt, it reads speeds of up to 161 mph. I never saw this issue using my previous speed sensor. Also, it often drops out completely and the display just reads N/A.
