I have a Droid 4 and use My Tracks to calculate my miles. I am using my tracks so I can upload the stats to Daily Mile. It wasn't until today that I noticed it had real time stats and speed until I took it out of my pocket during my ride. I am looking for a handlebar holder so I can see stats as I ride. What do others use to keep their phones on the handlebars.

I spent a while researching fairly expensive and cumbersome options until I realized that a cheaply made arm band for holding a phone while running would work very well.

I happened to already have one lying around that a friend gave to me -- he bought it for just a couple of dollars through Amazon. It was originally designed for an iPhone / iPod Touch, but it holds my LG Optimus V Android phone just fine (perhaps your Droid 4 is bigger, but I bet you could find something quite similar), although after using it a couple of times I cut away a bit of the rubbery material for better access to the buttons.

Pros:
- Cheap!
- Versatle: depending on which bike I use, I can wrap the stretchy arm-band material to hold it just about anywhere in either a portrait or landscape orientation.
- Not too rigid: it has enough give that it seems to absorb even major bumps quite well. My phone has never been knocked loose.
- Easy to get the phone in and out.
- Nothing stays on the bike, and it can readily be moved from bike to bike or, of course, my shoulder if I want to bike to the start of a run.

Cons:
- Looks cheap
- No weather protection, but a single wrap of Saran Wrap could easily take care of that, while still providing touch access.
- This would not be idea if you want it for constant display and reference. I use it for navigation, and even then not for constant reference. I only turn the screen on when I need to check a turn, and then I use my thumb to angle it just right for viewing. When I'm not actually looking at it, I turn the screen off and let it rotate so the phone is actually suspended, as shown in the second photo below.

Here's a photo of it mounted on my folding bike:


And here it is from the underside so you can see how the strap is wrapped around:

That is some good improvising there. Thanks for sharing this, I may try something similar.

I use the Minoura handlebar phone holder... works great... very secure... and it looks nice on my bike.
