Wahoo RPM Speed and Cadence Sensor for iPhone, Android and Bike Computers & TICKR Heart Rate Monitor Chest Strap, Bluetooth, ANT+

Upped my VR cycling to a new level

Options for attachment work just fine, settled for the offside crank arm. Appears to be perfectly accurate and there's no trouble interfacing it to either Wahoo Fitness or Locus Maps. It appears you can only link it to one app at a time.It's not difficult to get access to the battery to replace it, the holder pops open with the twist of a coin in a slot on the side.The silicone rubber holder that I'd have thought would have been ideal needs to be mounted in such a way that the cable ties used to secure it would have to be removed to remove it from the holder. Which doesn't make a lot of sense to me...Apart from that, the only other gripe was that the supplied battery was at 25% on first use. But then the thing activates on movement, so I'd imagine it must have been activating on and off all the way through the delivery from the warehouse. Might be an idea to have the battery separate or insulated in the device.Incredible that they've got the sensor, BT/LE, and microcontroller all tucked away in such a small case...

I bought this product as a way I could connect my turbo trainer to Zwift rather than buying a new expensive turbo trainer.For what I need it for, it does well. It is something to allow me to add miles to my strava.Accuracy: I can't really say to be honest as I haven't had the ability to compare it to anything. I have only recently began indoor cycling so there are too many factors that wont allow a honest verdict. Is it my turbo trainer making it harder? Maybe Zwift bluetooth connection? is it lack of hills? I don't really know, however I do seem to be having to work harder to maintain an average speed over an hour - Take from that what you want. I can't really say.Installation: I found this harder than I would have hoped. I don't have big hands at all but I struggled to get my fingers into the spokes of my wheel enough to be able to stretch the band round. I had to a bit of string tied round one end to allow me to pull it enough to reach over the hook. A Minor inconvenience that was acceptable for the price.Connection: It was super easy to connect to the Wahoo App and Zwift. In all honesty. I don't use the Wahoo app at all other than to first use it. I don't believe it was required to using on other apps. The product needs to move slightly in order to "turn on" but from there it was a simple case of using my phone to search for the blueetooth and pair it. Couldn't be easier.Battery Life: So far it has been good. Again, I can't really come to a verdict here as I haven't used it long enough but I am happy enough.Downside: The only downside I can really come to is there is a delay in my cycling to the connection to my phone. I understand that comes from any form of bluetooth device due to the nature of it but it does make stava fitness ramp tests near on impossible. I guess that has to be expected from the budget so is an ok compromise from my perspective.

Used with: Garmin Edge 1030This little gadget works perfectly. It was easy to fit using the double-sided tape supplied, since I have cranks with flat inside surfaces. In case you have cranks with curved surfaces, the unit comes with a snug little holder which zip-ties to the crank. It synced to my Garmin immediately, it starts up quickly and automatically, and it just works, every time. Cadence readings appear to be as accurate as you could hope for - there's often a delay of a couple of seconds before the reading changes in response to a change in cadence, but this could be the Garmin doing a time-averaging thing - it's not easy to update a display rapidly when measuring something that's only turning at little more than one rev per second. The big news for me is that so far, after using it for around 10 hours of riding, I haven't seen a single drop-out.It's certainly infinitely better than the Magene sensor I bought originally, and which went into the scrap bin after a couple of rides due to continual signal drop-outs. If you're wondering which of these sensors to buy, I'd recommend you buy this Wahoo sensor - don't waste your money on the Magene.I would have given this unit five stars, but I have to knock off one star because of the very soft plastic the sensor is made of - when the time comes to change the battery I think it's going to be difficult to prise open the battery compartment without causing some serious damage. Well, we'll see when the time comes, in the meantime I'm very pleased with it.EDIT: I've just bought a second unit for one of my other bikes, and it arrived with a dead battery. The manufacturer stupidly ships these units with the battery already installed and connected, so every time the unit moves while in transit, it gets activated. The first one I bought was ok, not so the second one.So as I had to change the battery, I was forced to find a tool to prise the unit open without damaging it. The only thing I can find to do the job is a ball-link plier used for separating the links used in RC planes, such as this one: https://www.amazon.co.uk/ATATMOUNT-Metal-Oblique-Helicopter-Repair/dp/B08NJR2WKS. I have two on hand and they do the job. If you don't happen to have one lying around though, it's pretty annoying to have to spend a tenner for a tool just to change the battery.

The wahoo sensors are very easy to fit, not using magnets (and offering Bluetooth and Garmin signal protocols) they are accurate over the ride - best ones I’ve used and having cycled for years I’ve used a lot.Two downsides and another upside - they can be a little fiddly to set up with whatever riding software you are using but the staff on the support desk are absolutely top rate and very customer focused. The only real downside is that the Wahoo software only uses chest worn heart rate sensor whilst cyclemeter is already linked to my Apple Watch -brilliant c,mon Wahoo get talking to Apple and get this feature added, you will have a world better solution then

Bought to go on my spin bike, easy to set up
