Well I was finally able to come up with secure way to mount my Eris to my Road bike, although I believe it is secure enough to work on a mountain bike to but I will have to try that later. I had been looking for a while to find a way to attach my Eris to my bike without the use of bulky devices like the universal one from the bike store. I finally saw the Shell / Holster Combo at Verizon and decided to give it a try. I purchased the Combo from Verizon for $23. Here is a link to the Combo. I have attached pictures. This Combo seems very durable so I think it is a good fit for this job. It says the phone is supposed to be faced in, but the holster doesn't appear to be causing any problems with the phone its just a snug fit. Which is what I want anyway. This is a pic of the holster only, I drilled 2 holes at the bottom of it to run a Zip tie for a more secure attachment. I will of course trim the zip ties but this is from the side. The clip on this holster is very firmly attached to the rest of the holster. I tried to pull it off and it was unwilling to budge. The final Look! The hole unit barely moves when the Zip ties are pulled tight. I am going on my first ride with this setup later today or tomorrow when it stops raining. Hope this helps everyone!
