Onlyesh Bike Speed Cadence Sensor, Wireless Bluetooth ANT+ Fitness Tracker Bike Speed and Cadence Sensor Speedmeter for iPhone iPad Wahoo Fitness Strava MapMyRide

Order this to go with Bryton 100E GPS Cycle Computer or with Samsung Galaxy Ace 3 - depending on whether I decide I need the Bryton!Ordered on Prime just before 11pm, and received next day (Saturday) early afternoon. So prime works fine... so what about this cheap unit?Packaging adequate, instructions sheet better than some... but not great, could be a problem if you haven't done this sort of thing before. Especially for the pairing part. You DO need an app that can read the data stream from the unit. Just pairing is not going to work. I found the Strava website support guides handy.Usual fiddling about to make sure of secure fitting of magnet on crank, sensors on the rear forks and tweaking to get readings. Loaded Wahoo app on the phone and waved a magnet at the sensors to turn it on. The sensor unit paired pdq. Initial tests indicated that it worked fine.Used Wahoo to log a short ride. Phone tucked in seat post bag as usual. All details (gps from phone, cadence from sensor) recorded successfully and the whole lot pushes across to Strava at the end of the ride with no bother. Ideally Strava would offer native device support inside their app, but that's not a quibble with this sensor.Never used one of these before, so time will tell as to how accurate and useful it turns out to be. I think it'll be more handy with the Bryton unit on the handlebars to keep my peddling in rhythm, but it works fine with by budget phone. Surprisingly painless experience for the price. Will update regarding pairing with the Bryton and how it survives the real world over the next few weeks.

Have been looking for some time for a cheap BTLE speed and cadence sensor. They are not complex bits of kit, after all, and I've had an expensive Wahoo one let me down (which, to their credit, they replaced, but it was a nuisance). This one is cheap and cheerful and seems to do the job nicely. Can't comment on weatherproofing yet and the supplied cable ties were brittle (a couple snapped before they'd even cinched up!) hence the mark down, but there's a good chance we will have more of these for other bikes, to save the hassle of moving sensors around.Note for Strava users, on iPhone at least - it identifies as a cadence sensor only (not a S&C combined), in their app. Make sure you have the right sensor 'switch' turned on. Wahoo app picked it up straight away, as did Zwift on Apple TV.

I'm using this with Strava and my Android phone (Nexus 5x) as a bluetooth sensor and it works great. Fitting of the Cadence sensor was really easy, though I have had some fun getting the magnet for the rpm sensor close enough due to the shape my bike frame. Pairing it up took about 30seconds and mostly consisted of spinning the crank/pedal. I'm very happy as it does exactly what it says and for an extremely reasonable price.

Bought to replace my Cateye speed & cadence sensor (ISC-11 I think) which keeps cutting out/losing connection, even mid-ride. Extremely frustrating. This works like a charm with the Cateye Stealth 50 cycle computer and has proved extremely reliable so far. Haven't had to change the battery yet either!Would definitely recommend.

...and now I know HOW far!Not the easiest set-up in the world, but I think I made it harder than it needed to be by trying to find YouTube instructions half way through. It didn’t pick up the speed sensor at first, so I’ve moved it a bit and it’s better now.First week of riding done with no obvious problems.

Bought this on a recommendation of a friend. I'm training for #LEJOG next year and needed to monitor my training on my turbo trainer. Once I worked out the angles the magnets and sensors needed to be at for it to register. It set up straight away with an app on my phone and registers every workout. Telling me exactly what I need to know to carry on with my training.

Seems to work really well, a breeze to fit and set up, it took no more than 10 minutes. Got it paired to Zwift by Bluetooth straight away and I was on the turbo trainer within half an hour.

I bought this for use with my fluid turbo trainer.It connects very easily to my phone (using wahoo fitness app), registers cadence and speed well whilst im on my turbo trainer. This allows me to track my workouts and upload them to strava (if you didn't strava it, it didn't happen).Very good cheap addition so you get the most out of indoor training. Will use my garmin 200 for outdoor training, so can't review it for that.
