"Phone holders for cars have become standard items for every driver who wants to talk while driving. However, many people commute by bike or use a bike for exercising. Yes, you could stick your phone in a pocket but then you don't see it, and seeing your smartphone can be an essential feature. I want to see who is calling. I use Ggoogle maps for new routes. I have a speedometer app that I want to see. I also want to see my playlist. I have to observe the stock market and I want both hands on the bar while I film my ride.
Welcome to Evotek's iPhone 4 holder 4Lock.
The Italian-designed phone holder can be installed easily and tool-free on any standard round bar or stem.
To put in the iPhone, all it takes is to press down the front of the holder, slide in the phone and press it down."
