Non bike specific gadgets. What do people have/use/seen? We’ve all got a strava device, heart rate monitor, funky lights, gopro etc. What else is out there that adds to the cycling experience? Not interested in electric gears or powermeters, I find the attraction of cycling me and the simple non electric machine. But gadgets as a periphery item do add to the whole thing and tick the tech head requirement.
