Wahoo Fitness Premium Speed Cadence Sensor

The Bottom Line

The Premium Bike Speed and Cadence Sensor by Wahoo Fitness is a nifty device. At around $60, it turns your iPhone into a high-tech cyclocomputer, showing your bike speed and pedal RPMs in an attractive, easy-to-read interface using the company's own Fisica app or another product. Sleek and low-profile, it provides the essential information any cyclist needs in tracking ride performance. Just be sure to reference the installation and mounting instructions provided on the company's website, rather than going by the minimal information provided in the packaging.

Guide Review - Review: Premium Speed and Cadence Bike Sensor by Wahoo Fitness

Wahoo Fitness offers a variety of performance monitoring options for use with its Fisica Sensor, one of the Ant+ devices that wirelessly connects your iPhone to devices such as your bike speedometer, heart rate monitor, power meter and more. This review looks specifically at the Premium Bike Speed and Cadence Sensor made by Wahoo Fitness that is used with their ant+ Fisica sensor.

First a word about the Fisica ant+ sensor. It's pretty straightforward. It's a small antenna that plugs into the base of your iPhone to receive signals from the performance measuring device that you're using and then displays it on your phone. It's about the size and shape of the base piece from your normal iPhone cord that you plug in when you want to charge or sync your phone, so this is something you'll automatically be familiar with.

Now, to the look at Wahoo Fitness' Premium Bike Speed and Cadence Sensor. This device simultaneously measures how fast you're going on your bike and how rapidly you are turning the pedals. The device is well built, mounting on your frame's chain stay (the part between your pedals and rearwheel, down by the ground), tethered there in a position that it can capture both the rotation of your wheels and your cranks as you pedal the bike.

In testing this, we had no problems with either the sensor detecting the wheel's rotation or the turning of the pedals once it was positioned properly. But the instructions included with the device were unhelpful in demonstrating where and how the device should be mounted. I've installed enough bike speedometer devices that I know how they need to be positioned, but if a person were unfamiliar with how these get set up, the instructions wouldn't be much help. And that's enough to make one nervous, particularly as there are zip-ties to be fastened and adhesives to be applied in this fairly permanent mounting step. Fortunately, a much-improved set of mounting instructions are available on the Wahoo Fitness website, but that link should be made known more widely.

In our testing, we found that the speed and cadence sensor had no problems transmitting this data to the iPhone via the ant+ sensor. The device itself is durable and well made. It's got a sleek, low profile, and the unit only weight 30 grams, including all of its parts. Once mounted, it stays put. The sensor read speed and cadence data under every condition that we used it, both in wet and dry conditions and in a wide range of outside temperatures.

Though Wahoo Fitness offers its own apps, the heart rate monitor is compatible with any number of fitness applications, including Endomondo, MapMyRide and more. A current list of compatible apps can be found here. Of the two Wahoo Fitness apps currently offered, the best by far is the Fisica Fitness. Avoid the Wahoo Fisica Utility, which only monitors current stats. The Fisica Fitness app is a nice general purpose training application for simultaneous use with the speed/cadence sensor or other sensors such as heart rate or power output, on par with ones like MapMyRide. It's easy to use, has a clear display of active stats, plus offers the GPS factor that shows your location in real time as well as allowing tracking and creation of a map of your route post-ride.

All in all, the Wahoo Fitness Premium Speed and Cadence Bike Sensor is a well made device and will serve your needs as a device to measure your ground speed and pedal cadence on the bike, and transmit that to your phone for ready monitoring. The key is proper installation, and for that, be sure to use the instructions on Wahoo Fitness website, rather than relying on the minimal information included in the package.
