You know how mum always nags you to be careful on your bike? You know, to indicate clearly, look behind at junctions and text her when you arrive? Hexagon (US$99, RM440) is here to put an end to this snowflake treatment. Stick it under your bum and it’ll light you bright to drivers behind, while a brake signal will activate automatically thanks to an accelerometer. Stick your smartphone in the partner mount and you’ll get rear-view footage, too, from the Hexagon’s in-built HD snapper, as well as turn signals and the option to stream your two-wheeled progress to anyone who cares.
