Arofly says its 10-gram device can read power, speed, cadence and other factors

Published December 5, 2016

NEW TAPEI CITY, Taiwan (BRAIN) — Arofly is a tiny device that installs on a bike valve stem and, the company says, senses and calculates data including speed, cadence, power, ride time, ascent and other factors. It transmits data wirelessly via Bluetooth to a smart phone app. It will also offer heart rate if used with a chest strap.

The company claims the 10-gram device can calculate power by reading tiny air pressure variances. It is marketing the device as an alternative to other power meters because it is less expensive, lighter and easier to install. It retails for $129. The company is seeking importers, distributors, and retailers.
