Bike Cadence Speed Sensor BK467, Bluetooth ANT+ Cadence Sensor for GPS Bike Computers, Tracking Cycling Speed and Distance RPM, Compatible with Zwift Wahoo Peloton Openrider Rouvy APP

Both sensor work and are accurate and very easy to set up…. They work with my Garmin cycle computer. The bands appear strong and hold the devices well, it would probably be wise to tape on for further safety if doing gravel or rough terrain…. Certainly good value for money alternative.

I just bought a new bike and wanted to fit speed and cadence sensors that would connect to my Garmin VivoActive 5 watch, so that I could accurately track my activities. These are great! Nicely packaged with rubber “bands” in a variety of sizes and two rubber backing pads - one flat for the cadence sensor and the other with a curve on it to help it sit snugly on a wheel hub. The instructions were clear and simple. Open the battery compartment, remove the thin plastic disc, replace the battery. LED flashes when battery inserted - blue representing Cadence setting, then remove and replace battery a second time and it flashes red to represent Speed setting. Once done they fitted onto the crank (cadence) and hub (speed) easily with the rubber bands. (There is also a spare of each of the three sizes just incase, which is a nice touch). Adding to my Garmin was simple - Settings, Accessories, (I have Auto Discover set to on), Add New, Speed/Cadence and it starts searching for the sensors. A quick spin of the crank and wheel activates the sensor and the watch “sees” it. You’ll add the speed and cadence sensors one at a time since they are separate units. Nearly done! You just need to configure the tyre circumference. Under Accessories you’ll see the speed and cadence sensors listed. Tap the speed sensor entry, and look for the wheel size option. I manually entered mine (no idea how the Auto option works!). You can either try and measure the outer diameter of the tyre and multiply by pi (3.14ish) or lay a tape measure out on the floor, place the bike with the front wheel valve at the 6 o’clock position and at zero on the tape measure and carefully push the bike forward along the edge of the tape until the valve has rotated once and is in the 6 o’clock position again. Take the measurement there and pop it into the watch. (My 700c road tyre was 2136mm just as an idea) Now you’re good to go! Just start the Bike/cycling activity on your watch and it’ll automatically detect the sensors as soon as you start to move. Accuracy looks pretty spot on as I used it on a track which is exactly a mile, and taking the best line around the track, after 5 miles, it showed the mile marker only around 10 feet before I crossed the start/finish line (and to be fair, I probably ran a little wide on a few corners, so the variance was probably down to the line I was taking, not the accuracy of the sensor!). All in all, very pleased with all aspects of these sensors, and they are quite discreet on the bike since they are two sensors with accelerometers and don’t rely on magnets attached to spokes/cranks to activate them. Photos show cadence sensor on Shimano 105 crank arm, speed sensor on Mavic rear hub and the spare rubber bands. The large was just right for the large diameter of the rear hub and the small for the crank arm. 6th Feb 2015 - Update - I was so pleased with these that I just bought the Coospo HRM chest band, which also came nicely packaged, was easy to set up and appears to work very well!

They do what expected them to do

Terrible quality, hooks broke after just 20mins into one ride using their provided elastic bands. Also speed sensor just won't link to my Garmin at all (255)

These are great. Fiddled round with batteries a bit to check I had one set for cadence, the other for speed. Paired instantly to both my Garmin Forerunner 55 and Cadence app on my phone, attached them to my crank and rear hub and hey presto my basic/dumb turbo trainer is giving me some useful figures alongside the heart rate from my Garmin watch. Not the be all and end all but definitely useful to be able to focus on holding your speed or cadence. Very good value and worthwhile I reckon.

I fitted these to my NordicTrack S22I bike I couldn’t fit the speed sensor to the bikes flywheel so I fitted it to the top on the pedal shaft and adjusted the wheel diameter to suit the speed that the bike was doing on my IFIT enabled bike and it works a treat.

Look no further. Easy to connect. Great display with max of 9 parameters on page. But page can refresh after 'user defined time 10-15-29secs' to a different set of parameters. Excellent set of cycling params to choose from. Export to Starva or Coospo apps. Although 'Bike computer' + 'heart rate montior' + 'cadence/speed sensors' can cost - I highly recommend the outlay for a superior product (I've tried lower end versions - bad choices). The eternal saying applies 'You get what you pay for'. Truely a *****(*) product. You will not be disappointed with quality and performance! ~ Paul

Arrived quickly and work well with the wahoo programme and hardware
