LEZYNE Bicycle Heart Rate Flow Sensor, High Performance, Comfortable, Lightweight, Bluetooth Smart, Cycling Heart Sensor

I have less than 6 months use with Lezyne Super GPS set (year model 10) and the HRM strap suddenly stopped working. Purchased this replacement Lezyne HRM from amazon and it won't connect either. Ironically, the older cheapCospo HRM I had connects instantly, with either brand's chest strap or battery. So clearly something is wrong and I have done all I can on my own. Updates/FAQ/user manual no help.AND NOW FOR THE UPDATE!I did get to talk with a very nice CS guy (hi, Alex ) at Lezyne and he was as perplexed as I. We even arranged a swap of HRMs to see what's up and in the meantime, the Cospo HRM stopped linking. Say whaaaa?AND NOW THE SOLUTIONWhen pairing up, I TURN OFF BLUETOOTH on my iPhone 4s. (YMMV).Once the lezyne super gps connects I can turn the iPhone Bluetooth back on.This only needs to happen if for some reason the head unit has forgotten my HRM ( or if a Russian hacker/ N. Korean baddie is messing with the ether nearby I guess).So all is well for now anyway. Go ride your bike.

The first HRM I purchased three years ago worked flawlessly for all three years until is broke which made it necessary to purchase a second HRM from Lezyne. My second one stopped working within 90 days of purchase to my sadness. I went my local bike shop and learned from one staff ,who is an avid cyclist, that Lezyne has had multiple issues with the reliability of the heart rate monitor and is aware of it. She shared that the Lezyne rep that services the store said Lezyne is aware of it, but has not made the necessary changes to improve the device. And with Covid-19 in play, customer service is all through and online ticket system, but there is little they can do but replace the device with, likely, another faulty device. To add perspective, I am a fan of the Lezyne product line and currently use their SuperGPS cycling computer, cadence sensor, speed and various lights. All have performed wonderfully with the exception of the second HRM. I hope this saves the next person the frustration. In the event, you are like me and have one of Lezyne's computers, then please know that any HRM that is ANT enabled will work with the Lezyne product, but you will likely spend a little more money for a quality HRM. For me, it is worth the extra cost to be able to train effectively.

Went for a solid ride with this yesterday and it worked great. It pairs instantly to my Lezyne Super Enhanced GPS. I don't have anything to do a proper comparison with the readings, but it seems like it's doing a good job. The strap is nice and comfortable. Just make sure you realize that as a HR monitor that uses electrical impulses (most chest strap monitors do) that the contact points may need some moisture on them before they get a solid reading of your heart rate. Anyway, I'll update if I have any new findings.

I have had great success with this. The key: I adjusted it to fit before using it. If you break the clips, it is set up way too tight. If you break the snaps, you are pulling the transmitter off the strap with too much force. I only unsnap one side of the transmitter after my rides, as this is enough to break the circuit and save the battery. I have around 100 hours on mine so far, and the battery still registers at 90 percent.As a side note, kudos to Lezyne and others for finally standardizing their power sources. For devices that do not have rechargeable batteries onboard, they now seem to all take a CR2032 battery. Thank you.

I live at Manaus, in the hot and humid Amazon forest heart. It did not last one single month and is already do not working. I do not recommend this product if you sweat a lot, like me. It should be more water resistant.

I really wanted to like Lezyne's products, but they just do not work. I bought this to pair with my Lezyne Super GPS, but I had so many problems I gave up. First, it took up to ten minutes before each ride for the GPS and HRM to pair up. Then, during rides I would either get completely unrealistic readings (such as a steady hr of 100 for the entire ride) or the head unit would drop the hr. I called Lezyne, and, although their customer service was nice, we were only able to resolve the problem for a single ride before the fix the engineers prescribed stopped working. Then, one of the small metal snaps that attaches the send unit to the strap broke off. So it will be back to Garmin for me.

The HR Monitor case plastic is VERY thin and BRITTLE, My battery compartment lid broke on the first attempt to use it. TOTALLY Worthless now. I own their lights and have been pleased with the quality of those, but this thing is a huge negative to thirr brand.

I bought the heart rate monitor and it broke in 2 months. One of the snaps broke off and was lodged in the strap. Tried contacting Lezyne and got no response to my warranty question. I also found out many others jad the same problem with tje monitor. In my opinion, Lezyne needs to do better at customer service.

After about 15 uses it stopped working. I've changed the battery a few time but the device is nowhere to be found. Trying using my phone or the lezyne mega c GPS to connect with it, sadly no such luck.On the rides it did work it would take about 10min to accurately read my HR and there's been moments where it would drop the reading midride.Such a shame, as I'm very happy with the actual GPS device.Anyway wouldn't recommend it based on my experience.

Ho un speed & cadence sensore della Lezyne ed un Lezyne Super GPS, quindi ho acquistato anche il sensore frequenza della stessa marca.Ha funzionato una sola volta, poi è stato impossibile fare il pairing con l'unità GPSLe ho provate tutte:- cambiare batteria- resettare ai factory settings il devicedelusione estrema.

Der Brustgurt passt ganz gut. Leider musste ich mir einen neuen kaufen, weil der erste nach nicht einmal einem Jahr kaputt wurde, es löste sich eine Verankerung vom Gurt und war somit nicht mehr brauchbar. Der Preis passt aber.
