Introduction & First Glance
The era of smart phones and apps created for the various phone operation systems revolutionized how mobile phones are used : people use their smart phones to navigate around places, check out the best places to have a meal (especially for Singaporeans) or even ‘chop’ virtual fruits when they are bored.
Most of us who are riding use cycling computers to track our speed, distance rode and time taken for a given ride. It is even more important for those of us who are training to reach a certain fitness level or prepare for races or events. If you own an iPhone 4S or the newly unveiled iPhone 5, you could use your phone as your cycling computer unit with the Wahoo Fitness Blue SC Speed and Cadence Sensor!
One of our staff in the Togoparts Team used the Fitness Blue SC Speed and Cadence Sensor (together with his iPhone 4S) over a period of 2 weeks for his commute to and fro work and we would like to share some of the feedback gathered from using the product.
What’s In the Box?
The Speed and Cadence sensor, magnets for each of the sensors, rubber gripper for the sensor and 2 supplied cable ties (not in picture). There is a quick start guide brochure with the QR code which provides the web link for basic set up and an instructional YouTube video.
Installation and Use
Setting up is a case of securing the rubber band and cable ties. The only real ‘challenge’ is that of removing the pedal on the non-drive side crank arm to slot in the cadence magnet. While it is designed this way so that the cadence magnet would be secure on the crank arm, perhaps an improvement in future would be designing a cadence sensor which can be installed securely without the use of any tools. Our tester did not remove the left pedal and just secured the cadence magnet on the non-drive crank arm using the cable tie.
One thing to take note is the requirement of both the magnets to be within 3mm of the sensors so that the iPhone unit is able to pick up the ride data accurately. The sensor utilizes Bluetooth 4.0 to pair with the iPhone 4S/5.
The user also needs to download the corresponding App on his/her phone and do the pairing between the phone and sensors.
Our tester used the product without mounting the iPhone on his bicycle. Rather, he chose to review the ride data after completing his rides (see below). Of course, there is a Wahoo casing and mounting accessory (sold separately) for those who wish to read the data during their rides. If not, any other type of third-party mount works just fine. The sensors were firmly kept in place despite sometimes bumpy road conditions and readings on the phone were quite accurate.
Another useful feature is the availability of various screen interfaces (see below) so riders can choose their desired interface based on the information and data they prefer to read.
As a whole, the Wahoo Fitness Blue SC Speed and Cadence Sensor for iPhone 4S/5 works well if you happen to own either model of phones and would like to use them as an integrated cycling computer. The drawback is anyone else (those using Android platforms on their smartphones or BlackBerry) cannot use it, though Wahoo is apparently working on a version which works with Android phones.
