4iii is a Canadian company relatively unknown to the general public… and yet, we owe it the ANT+ technology, a communication protocol that has become standard for wireless fitness equipment. 4iii was then called Dynastream and the ANT+ business was sold in 2006 to Garmin. Today, 4iii is focused on developing equipment to give nearly everyone access to advanced technologies to train like the pros. The brand has thus launched a power meter that is both simpler and more affordable than existing products until then. A model that is evolving today to integrate into Apple’s Locate network. The idea is of course to allow you to find your bike efficiently in the event of theft.
A power meter, késako?
But first, a small point on the Precision 3+, the name of this power meter. This is a small waterproof case that sticks to the left crank of your road bike equipped with a Shimano or SRAM drivetrain. It conceals several sensors whose data is processed by algorithms developed by 4iii. Weighing only 9 g, the case, which is of course water resistant, will make it possible to precisely measure the power developed in watts by the cyclist and the pedaling rate. Very important data for those who want to train and improve. Everything is based on a CR2032 battery given for 800 hours of autonomy. Bluetooth and ANT+ are present to communicate with the iOS or Android application which collects all the information.
4iii now brings it compatibility with Locate to turn it into a kind of AirTag, which is the main difference between a Precision 3 and a Precision 3+. To find his bike, the cyclist can rely on the network of over 1.5 billion iPhones. By launching the Locate application, he will be guided to him, like what VanMoof offers on its latest generations of biclous. The brand markets different versions of its system so that it adapts to the specific model of your crankset and the length of the cranks. The prices vary between 335 and 530 €. Although it is not yet available in Europe, an upgrade, billed only around thirty dollars, is offered in the United States to transform a Precision 3 into a Precision 3+, which allows access to the Apple Locate function.
