As the name suggests, the Smart Pro 2 is one smart indoor trainer, specifically when it comes to resistance.
It connects wirelessly to the Bkool app (via Bluetooth Smart or ANT+) which controls the resistance level automatically. Using magnetic fields to hold you back and give you something to push against, it claims to handle up to 1,200 watts of power from the rider. The Bkool app provides virtual worlds and videos to simulate real-world riding, and it can even simulate riding inertia, using technology borrowed from its more expensive big brother. It’s also compatible with other riding simulators such as Zwift.
A versatile and reasonably affordable way to get involved in the world of virtual online training.
