Sunny Health & Fitness2-in-1 Advanced Cadence/RPM + Speed Sensor, Cadence Sensor Bluetooth ANT+ for Indoor/Outdoor Bikes, Magnet-Less Design for Outdoor Cycles, Exercise Bikes, and More - CB110S

What else is there to say? It turned my old SunnyFit bike into a newer one for less than 100 bucks. That’s a win in my book!! it was super easy to put on and the app works great. I love being able to use the “world tour” function. Absolutely love the upgrade to my old beloved piece of equipment.

This product connects every time and is easy to utilize. No need to a manual... just hook it up, turn on bluetooth, and off you go.

works well and does what it should. I cannot keep the little rubber pad between the sensor and the pedal arm for anything so I gave up on that. Easy to connect to but it’s not an automatic process.

I have a Sunnyfit exercise bike and added this cadence sensor to get data on my phone. It installed easily and paired with my iPhone without any problems. When I start a workout, it's nice to see the data on my phone and track workouts in the Apple Health app.

Just purchased sunny bike and needed to be able to track my cadence and speed and this thing was so easy to install on the pedal crank and pair with bluetooth. Works perfectly and now I can track all my workouts!

It doesn't work, I feel it's built for indoor bikes, not outdoor bikes. I have an outdoor bike and just want to track my distance and to track along with my dad who has a recumbent bike. It will not hook up to the app.

I used on an old spincycle. Took over an hour to connect correctly to sunnyfit. The software kept telling me it could not connect. When actually it connected, I just had to start a workout. Free mode does not work.

Huge Sunny Fitness Fan! Just picked up their cadence sensor to add to my bike (SF-B1877) and I'm go glad i did! I'm not very tech savy, but set-up was super easy. Took me 2 mins once the sensor arrived. Sunny includes these bands that you simply clip onto the side of the pedal and your done! Just make sure to download the app first (its free!) choose the bike you have from the list and it automatically starts to record! It took me a few minutes to figure out the app, but once i got it i was happy to see all kinds of fun features including milestones and awards to help challenge me and keep me motivated (every little bit helps!) Will post an update in a few months if things change, but right now this was exactly what i needed to help keep me motivated about getting my daily dose of sweat-therapy!
