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.
Paired successfully with my Wahoo Element but then spent most of the time reporting zero rpm interspersed with occasional other numbers that were clearly wrong.
Possibly a worn out battery since Wahoo stupidly ship the device with the battery enabled (on a device that switches in when it reacts to movement - brilliant!). However I didn't bother to investigate further as a brand new item should just work. Wahoo make some great products but clearly have quality control issues as I also received a faulty Tickr in the same order. I received a replacement Tickr that seems to be fine but I just returned and refunded the cadence sensor and bought a much cheaper chinese version instead that worked first time (and came with the battery disabled initially, fancy that)
I’m a big fat fatty of man- wash myself with a rag on a stick, local takeaways Know me by name, eat butter out the tub, the lot. Bought these to use Zwift on my iPad and loose the chub, and it’s working, I’m shedding pounds like crazy. £12.99 a month to be precise for the Zwift subscription.
This has been on my bike for a month and it's worked perfectly. It's paired instantly with both my phone and my Elemnt Bolt. I used the neoprene mount and supplied zip ties to attach it to my crank, which is a little ugly but avoids the worry of the double-sided tape falling off. You really don't have to think about the sensor: just get on the bike, start your GPS tracker and go. Everything's completely automatic. The readings it's given have been plausible and consistent.
My only criticism is that the supplied "Quick Star Guide" is completely inadequate and I had to go to Wahoo's website for proper instructions on how to mount and pair the device. (This seems to be a consistent failing with Wahoo's products.) But, hey, you mount it once and then it just works.
The battery in this one is a CR2025 and the opening slot at one end chips off when using a coated screwdriver. It works sporadically for about the first 3 - 4 minutes a ride. The battery it came with did not have the usage protection piece, so it had only 4% charge. I'm thinking I got a lemon or a used/returned lemon or super old product. I'll buy from my LBS instead, which deals directly with Wahoo. I spent over $60.00 for crap and due to chipping on plastic case from screwdriver (yes, I'm very careful), it won't be accepted as a return. Plastic is so brittle. I'll be checking with Wahoo on the SKU to find out how old this actually is.
Packaging is so much better that Garmin. Gone through 2 Garmin cadence sensors - they just fall apart. The Wahoo packaging seems more robust despite using zip ties (which are easy enough to come by). Connected to my Garmin 810 without issue.
Early days, but I would recommend this over Garmin's cadence sensor.
The instruction in the box says place it on the outside of the crank arm but that's impossible as there isn't enough room and it runs on your shoe. Finally got it working only for it now to stop working. First signs were that Zwift appeared to be reading a cadence figure much less than the wahoo app on my phone. Now the phone won't connect even though the light flashes on the device so there is some power. Changing the battery should be simple but you end up butchering the plastic using a screwdriver and twisting which is the method suggested - even using multiple size screwdrivers it still wasn't "prizing" off as the online instructions suggest. (Nothing in the leaflet supplied). Only had the device a few days so I assume battery supplied is dead or else the unit is faulty. Will update review once I buy a new battery!
Used with: Garmin Edge 1030 This 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.
Bought this less than a month a go to replace a Wahoo Speed/Cadence sensor that was being inconsistent. Given I had the previous sensor for a few years was happy to spend money to replace it. Unlike last sensor, no magnet on wheel reqd, just strap sensor to crank or shoe and good to go. Well, it did well for about the first 2 weeks then by last week it started to be a bit hit or miss and by this morning it had failed completely, after only 4 rides. It "may" be the battery but surely this should last more than 4 rides in the space of 4 weeks?! The wahoo head unit (which is a great piece of kit) that is used to display the cadence seems to be working fine as able to communicate with all other sensors without issues and, as I say, was able to communicate with this sensor for the first 2-3 weeks without any issues either. If I do decide to replace the cadence sensor, I will be choosing a different brand the next time
I bought this originally to try to fix an issue with a Kurt Kinetic trainer as they have withdrawn support for cadence in their firmware. It didn't really solve the problem so I am using it on outdoor rides. I like the option of being able to attach it to the straps of cycling shoes, assuming they are velcro and not lace of course, and that the straps are narrow enough to fit. Otherwise, using the supplied rubber sleeve and cable ties, it is easy to attach to the bike. The one I have linked OK to my Polar V650 but I do seem to get something of a lag it the data appearing: that may be more to do with the Polar than with this product of course. One thing I am slightly disappointed about is that having only had it a few days, the Polar is reporting that the Wahoo's battery is at less that 50% charge. It is a CR2032 type battery so not difficult to change, but I am wondering if battery life will be a problem.
This is the second set I have purchased, the first was sold with the Wahoo Elemnt as a package and then when I bought a new gps system for the bike I went straight for the Wahoo sensors. Very easy to fit to the bike, not much mor to say about that. Now using a Hammerhead Karoo 2 GPS unit and as soon a I hit pair sensors, the Wahoo speed and cadence sensors are picked up and have, as expected performed faultlessly. No dropouts, no unexpected spikes, just reporting what was happening. There are cheaper alternatives but you do tend to get what you pay for and I’m VERY happy with Wahoo!
