It's tough to find a good spot for your iPhone 4 when you're riding your bike. Pro.Fit presents a convenient solution — this two-piece kit combines a handy mount and secure holder that'll keep your iPhone 4 strapped safely to your handlebars or stem as you ride. It's great for road, mountain, or commuter bikes.

The Pro.Fit mount provides a secure base, while the holder grips your phone snugly. A wrap-around, flexible safety strap keeps it from ever falling out. Warranty: lifetime.

Note: This holder is not designed for off-road use (it won't protect your mobile device from inclement weather or crashes).

Secure and good access to screen; covers speakers

Crutchfield Customer Review (What's this?)

Overall I am very happy with this and would recommend it.

It holds the phone securely while still providing adequate access to screen...which are the 2 biggest complaints against the competitive products.

However it will NOT protect your phone from rain or sweat or crashes. And unless you have a very slim cover, you will need to remove it from phone before putting phone in the bike mount.

The bottom part of the bracket covers the speakers so if you listen while you ride, music is muffled a bit, maybe 25% at top volume. Nuisance but not a deal breaker. Volume buttons are covered, too, you need to use tap screen to adjust volume.

It is easy to install. The mounting can be put on the stem instead of the handlebar, but unless you have a very long stem the angles will prevent it. Tried to insert more padding to elevate the bracket, but that made mount too unstable.

It can be mounted horizontally, but the strap still goes the long way, it does not rotate. The mount itself does not swivel, but this is a benefit to stability and security.

Good product that is functional and will meet your needs without being overly complex.

Overview: The Pro.Fit BK-4R iPhone 4 Bike Mount and Holder allows you to attach your iPhone 4 to the handlebars or stem of most commuter, mountain, or road bicycles. The holder base is held in place using 2 supplied zip ties, while the iPhone 4 holder attaches to the base with the supplied hardware. Once the holder is mounted to your bike, the iPhone 4 slides into the holder and is held securely in place with the elastic safety strap. It is not recommended that you remove the phone while riding. The BK-4R is designed specifically for the Apple iPhone 4. This holder will not work with skins, covers, or other iPhone 4 accessory cases.

Note: The BK-4R is only for holding the iPhone 4 while you are riding. It will not protect the iPhone 4 from inclement weather or crashes.
