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

Fortunately the unit isn't too delicate, as I managed to drop it twice. Removal/fitting the battery cover is a little tricky, but there are two reference arrows to indicate when cover is locked. Once the plastic isolator was removed it worked instantly, flashing blue or red depending on mode set. I found attaching unit to hub difficult until I used strip of tape to secure, then both hands to fit rubber band. Recognition with my Wahoo app was immediate on spinning wheel, then straightforward to pair. Road test proved satisfactory, speed data showed same as fitness watch; and unit remained firmly attached.

Excellent cadence sensor. Purchased it to replace my Polar cadence sensor as the battery cannot be replaced. This cadence sensor gets a 10/10 from me as I’ve just had a 30 miles off road test run with the sensor and it performs great. Instantly synced to my Polar M450 head unit. It’s great that this unit will not end up in landfill as you can very easily replace the battery. A well designed unit.

Works fine with its own App, only small downer is it doesnt show calories used during the work out. It does show them once you have finished though. Hooks up to app easy and on indoor bike you can share sensor with others all on own app. Easy switch from spped to cadence.

Over the years I have had four Coospo speed/cadence sensors and an H6 Coospo HRM. All are still working without a problem. Never had a problem connecting these devices to my Garmin GPS cycle computer or my Garmin watch or cycling apps such as Bkool, Ruvee and Wahoo SYSTM and RGT. At the price they are very good value for money being at least half the cost of some other brands. The only problem i have had was with my H6 HRM dropping it's connection with my Polar V650 bike computer. After buying a Wahoo HRM I realized the problem was with the Polar V650 and not the Coospo HRM.

Quick delivery, bought to replace the built in cadence monitor on my turbo trainer. Easy to link to ROUVY & Zwift works as intended
