Any ideas?
All I need is cadence and distance. Must work with Ant+ sensors.
Just need something to show me the time as I commute so that I know when its time to make the turn and head to the office in the morning.

You can run the strava app on your phone. You'll need a good mount if you want to see it as you ride. Don't skimp on a mount.

Yes I know that but I havent found a mount I would trust at all. I also want the cadence to display.

I was going to suggest "Ride Report" android app, because it automatically detects when you're riding and syncs it to Strava. You don't have to start the app, touch a button on the app or anything else, it just runs hidden and does it.

But that doesn't provide cadence distance and speed. I think if you want all that plus auto syncing to strava, you won't find it in a cheap bike computer. Plus, it's going to need network connectivity of some sort to talk to Strava, and if you have to take it off and plug it into a USB cable every ride, that's not very automatic. Maybe there's a Garmin model, but not cheap. My suggestion is to use a cheap wired computer for candence and speed, and use the phone for Strava.

I've had a lot of mounts. Most seem to be crappy. One even dropped my phone! Quad Lock is the way to go. I totally trust it, and it's worth the relatively high price. Ridewithgps will display your cadence if you have a cadence sensor that sends to your phone.

You can always use a cheap phone that has ant support - just use it a bike computer exclusively. Some of the older models are getting very cheap now - example my Motorola E was $30 new from Ebay. No need for a mount - just sand the back of the phone and glue on a garmin mount (under $5 on Ebay ) to you favorite garmin mount (eg stem or "out-front" and on ebay for under $5). My whole setup was under $50 and has ant support, maps, the works.
