Cycling Speed & Cadence Sensor, Bluetooth & ANT+, IP67 Waterproof | Bluetooth & ANT+ Dual Protocol, Speed/Cadence Mode Switch, 9.2g Ultra-Light, 300h Battery, Tool-Free Installation

I bought a pair of these to try to convert my Merach under desk bicycle into something that would play nice with tracking reasonable data for indoor bike activity via my Garmin ForeRunner 965.Both of the Cyclus sensors connected without issue to the watch via ANT, with a pedal icon for the cadence setting, and a speedometer icon for speed setting.Accessing the battery compartment is a bit strange, as instead of twisting the back panel in a full circle, you just set the dial to directly between the two possible settings, then gently pull it open. These ship with a plastic sheet between the battery and the connectors, which needs to be removed before they'll boot up.These were a tight fit on the cranks, and I could just barely slide them into place on the inner side, as long as I didn't add either of the rubber pads. They stay in place just fine without them, however. As my picture shows, the fit was tight enough that I got some white circles on the inner plastic cover while using them from some light friction. Unfortunately, in this position, I can't see the light indicators for their remaining battery life, but I'm glad there was a way to make them attach!Perhaps unsurprisingly, installing only the cadence to the crank had no impact on the watch's speed or distance calculations during a test cycle session. Lacking access to any wheel hub, I wondered if it would be possible to get acceptable readings by getting creative with the calibration and attaching the speedometer to the other crank, similar to how it installs for cadence. And as it turns out...yes!Repeatedly manually adjusting the "wheel size" calibration for the speed via my watch, I kept doing brief test runs and comparing the speeds to the built in LCD panel on my bicycle and my watch readings to calibrate and dial things in. With a manually set wheel size of 43 43 mm, it was pretty consistently within a 0.1 to 0.3 mph margin of error during glance comparisons at the speed gauges when pedaling with a consistent speed in my usual pedaling speed ranges, which is anywhere from 9mph to 16mph.After making sure to clear data stored on the bicycle so both were starting at a distance of 0, after a longer cycling session of about 1 hour and 30 minutes, the built in panel on my bicycle read a distance of 15.6 miles, and the final distance report from the Cyclus sensors to my watch was 15.3 miles. So extremely close! When initially writing my review, I thought the final distance gap was larger after another extended ride, but that was user error in setting up my comparisons, so I re-did my test to get a more accurate comparison. So, I feel pretty confident in the manual calibration of 43 43 mm as a starting point to calibrate the accelerometer, if installing both the cadence and speed to an under-desk bicycle via the cranks, even though that isn't the recommended install method. The tension control on my bicycle was set to the highest setting (8), if that matters at all in any of these calculations.While I am using them in a somewhat unconventional manner, these Cyclus sensors were still a nice upgrade to the functionality of my Merach bicycle, and I'm quite happy with them!

Works great! Easy to configure and install on bike. Was a great value. Would recommend this sensor. Works well with GPS bike computer and Wahoo app on my iPhone.

I bought this sensor along with a bike computer and a mount. I have issues with both the computer and the mount but this sensor has been pretty great.I set it to speed sensor and mounted it to my wheel using the included rubber bands. I used it with the cycplus m3 and it worked well. When I returned the M3, I went out and purchased a Coros Dura computer and paired this sensor to it with no issues. It works really well and has stayed connected during my rides.For the price, I may purchase a second one to use as a cadence sensor.

For a dumb trainer indoors. AI recommended a couple of apps for this, the instructions hadn't specified that. One app was broken apparently, and the CYCPLUS app mysteriously no longer on Google Play.I got Wahoo fit and works great. I would have gone with the Wahoo sensor just to reward their having an impressive app that works.

I have purchased 9 of these sensors and used them for over a year and a half. They are easy to install, connect readily with my Garmin Edge Explore 2 cycling computer, and provide accurate readings. I have not had to change any batteries yet.Great warranty support too! I recently had trouble with a sensor reporting inaccurate cadences. I contacted the company and asked for help. They immediately replied and sent a replacement after I provided proof of purchase and documentation of the faulty output. CycPlus warrants these units for two years.It is important to tape the sensor to your crank to ensure it stays on in rough conditions. The rubber band mounts work well most of the time, but I have lost two units while gravel riding. I recommend using self-fusing silicone tape to ensure that they stay in place.

There are many inexpensive switchable speed and cadence sensors available on Amazon. Almost all "switch" in response to a battery disconnection/connection. The problem with this is that this can happen unintentionally, particularly when the battery is weak. The symptom (if you're intending to track cadence) is that the sensor silently switches to "speed" mode, overriding your GPS, and replacing it with speed and distance values that are about two-thirds too low.This model has an ingenious, and I think unique, design: you switch between cadence and speed mode based on whether you close the battery cover clockwise or counterclockwise (it's very well marked). This makes it impossible to get it wrong, and impossible for it to change accidentally. For this unique and important feature, I give this five stars.

Purchased this awhile back for use on one of my bikes that is at my in-laws house. Was planning a multi day self supported tour and didn't have a ANT+ sensor on the bike up there. Instead of removing and bringing my Garmin one, I bought this CYCPLUS one.It didn't work then. Would be really spotty about pairing with a Garmin Edge 130.Fast forward some time, I brought it home and had it on my shelf. Have another newer Garmin since then and thought I'd try it on my city bike / hybrid bike. Set up ok, but even with new battery it would lose signal from the Garmin. I'd only know this as the Garmin popped up a notification every time it would re-connnect.I've had other sensors, both Garmin and also third party. All have been reasonable and easy to use except this one. Not the best in quality and way past time I can send back.Save your money. Time to pass this one by.

I needed to replace a Garmin Speed Sensor which had started to malfunction after many thousands of miles. I decided to give this one a try and while it does the job, it comes with pros and cons, compared to the more expensive Garmin it was replacing.PROS:1. When idle, it turns off quicker than the Garmin. Thus, saving the battery life for the sensor unit.2. Cost, it's almost half of what you'll pay for a Garmin Speed Sensor.3. You can use it either as a speed sensor or cadence sensor.CONS:1. If you use it as a speed sensor, it's a major bitch to get this unit secured on your wheel hub. Garmin units come with a rubber housing that you insert the unit into and is a breeze to get on the hub. This housing also keeps the sensor pretty protected from water. Unless you have tiny fingers on your hands, you're going to struggle mightily to get the O-ring stretched around the unit and hub to secure it.2. Every 3 minutes, it turns off for a fraction of a second and then turns back on. When your bike computer senses this, it turns on to tell you that it "found" the sensor and is working. In that fraction of a second, your average speed drops by ¾s of the actual speed you are traveling. Riding at 16 mph, then it will drop to 4 mph, 20 mph, then it drops to 5 mph and so on. If your cycle training for a triathlon or just want accuracy for your average speed over the course of your ride, this glitch in their software will affect the accuracy of the data that you are trying to procure.3. Also associated with this three minute glitch problem, your bike computer re-awakens, so if you have it set to "battery saving" mode, which on a Garmin means it comes up at full illumination for 15 seconds, you're wasting battery life before your computer goes back into saving mode again.4. Finally, if you have "tones" turned on, then this three minute re-awakening causes a beep to be sounded and if you're riding a route, you instantly look down to see if you have to turn onto another street in your route. I never like to look away from the road I'm traveling on if I don't have to.I should have just spent the extra money and gotten another Garmin. I'm going to try it out as a cadence sensor. But if this same problem persists using it in this mode, then it's going to be regulated to an emergency backup in case any of my Garmin speed sensors malfunction or die outright and I need something to use until a replacement Garmin sensor can be purchased.

Económico y fiable.

Collegato al T-rex amazfit ed è perfettamente compatibile.Leggerezza e versatilità ne fanno un portento

Snabb leverans och produkten fungerar bra!

I needed a pair of these for my Datsun stationery bike, one used as speed sensor and the other one as cadence sensor.The tricky part is to install the speed one on the center of the disc. Once tie rack it, I use the double adhesive cut to fit the sensor surface.Make sure cadence on pedal and speed on disc.Next is to pair them with free mywhoosh hd app and I'm good to ride on the streets of Japan or Australia.Works like a charm and motivation has never been that strong when you watch yourself competing instead of watching a wall.

Prodotto conforme alla descrizione e consegnato nei tempi previsti. Però far pagare 5,90€ ad un utente Premium mi è sembrato eccessivo visto anche il costo del sensore (comunque mea culpa che mi sono accorto all'ultimo momento).
