Find out what your most efficient pedaling rate is and measure your speed and distance accurately. The sensors included in this set work with Bluetooth Smart technology and consume only a little energy. Light yet tough, and easy to attach. Compatible with Polar V800 , Polar V650, popular cycling apps, the iPhone 4S and later and select Android devices using Android 4.3 or later Review: The only way (I know)to instrument a non standard bike, but good for any bike. kudos to Polar! - I Ride a terretrike sportster, the crank and back wheels are separated by geometry (tadpole geometry.) I taped (monkey grip duck tap) a stack of super magnets (about 1/2in fia) on the back side of the pedal bolt, leaving a small clearance (I used a stack as the very strong magnets fit neatly in the hole and are nearly secure without the black tape) the rear needed only minor modifications. Both linked to my iPhone simultaneously in addition to a bluetooth polar heart monitor, running Cyclemeter and work like a champ. I rolled my back wheel in the parks ng lot ten revolutions ( lazy) for 66.6 feet, verifying with a hundred foot tape measure. A decided improvement in distance measuriment, as gps distance does not seem to correct for altitude changes. Additionally they all works indoors on my training rollers. An industrious person could make an adaptor swing aluminum cylinders and a zip strip with super magnets and JB weld, for the front attachment. Review: Excellent Products ! - These are great speed / cadence sensors ! I have used similar Polar sensors in the past paired with a Polar watch. When the watch died, I tossed the watch and sensors. Now, not wanting to purchase a new watch for in excess of $200, I purchased the sensors again and paired with an Android 14 tablet. I no longer ride on the street so using a tablet is not a problem for me. I had been using the Polar Flow app to monitor my HR during workouts. It is a shame these sensors are not supported within the Polar Flow nor Polar Beat apps. I can imagine that would cut into Polar's watch sales. I have paired the HR / speed / cadence sensors with the WAHOO app and it works great. I had attempted to use the MapMyRide app but that app did not seem to recognize the active sensors although published it would. These sensors are easy to install and the WAHOO app supports the entry of wheel size for the speed sensor. Other apps may work as well. I highly recommend these sensors. ## Features - Improves your cycling technique and performance - Speed sensor accurately measures your cycling speed and distance.

Much smaller than I expected them to be. Disappointed that the batteries are not replaceable. Not sure if I missed that detail in the description but read it in the instruction booklet. I will not pay $100 for another set when the batteries die off, so I may be doing some surgery on these when the time comes. Not sure what polar was thinking by not making the batteries replaceable. ## Frequently Bought Together - POLAR 91047327 Speed and Cadence Sensor Bluetooth Smart Set - Polar Pro Chest Strap - Heart Rate Monitor Belt --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.kg/products/21794369-91047327-speed-and-cadence-sensor-bluetooth-smart-set](https://www.desertcart.kg/products/21794369-91047327-speed-and-cadence-sensor-bluetooth-smart-set) --- *Product available on Desertcart Kyrgyzstan* *Store origin: KG* *Last updated: 2026-08-24*
