Most modern GPS bike computers don’t actually sync directly to Strava via Bluetooth on the device itself while sitting on your handlebars; instead, they pair via Bluetooth to your smartphone app (like 
Garmin Connect, Wahoo Elemnt, or 
Hammerhead), which instantly and automatically pushes the ride file to Strava the moment you save it.
Here are the top, most reliable GPS bike computers that seamlessly auto-sync your rides to Strava through their companion phone apps:
