Good Denizens of the forum!

I've become accustomed to having a basic cycle computer for time, distance, and speed, but as I've added bikes, I encountered a problem where I'd have to keep buying cycle computers to dedicate to a bike. Now, I know that some are capable of tracking different bikes, and some can do that automatically. For 4 bikes, the cost is still higher than 4 basic computers.

I've also concluded that I could benefit from tracking my cadence so I can train for more spinning and less mashing. The expectations have spiraled out of control from there...

I'm considering basic computers on each bike, plus a shoe mounted wahoo cadence sensor paired to Strava. A final piece, once I save enough, could be a smartwatch capable of monitoring heart rate for advanced workout information.

Tell me though, what do YOU do, or would you do in this situation?
