Bought from Bunnings for $45 or $6 - lincraft or craft shops didn't have double sided velcro

The velcro is ideally a bit wide, but only needed to wrap it around one side of the sensor, but I haven't done any sprinting or anything yet to test it out

Cable is very roughly tied to the top tube and then up to the headstem

Excess cable is wrapped around bars and head stem and then I cable tied the handle bar mount to the head stem so it isn't permanently attached
