Bike Mount/Holder for iPhone 4
When you're going on a big bike ride and want to stay connected to your iPhone 4, you need a bike mount/holder for iPhone 4. Designed exactly the same as a bike computer mount, this lets you attach your smartphone securely to your bars, stem or top tube.
A huge advantage to taking your phone on a bike ride is that with the right apps, you don't need to buy a separate bike computer - the GPS feature on your phone will track every inch of your ride.
Types of bike mounts
Most bike phone holders are simple plastic brackets that attach to your bike, with a place on top for you to clip your phone. Most have some kind of transparent pocket that keeps your phone dry in the event of a downpour or if you're cycling over muddy or wet terrain. The clear covers allow you to both see, and access your phone while riding, so you can check your speed, route, distance travelled and more.
You can buy the mount and case separately, but you need to check that they are compatible with one another. However, there are many branded models which fit together, so as long as you choose the right brand everything should slot neatly onto your bike. Brands that produce bike mounts include Apple, Arkon and iOttie .
One of the advantages to buying a mount and case separately is that you don't need to buy a new mount when you change phones - simply buy a case that fits your particular model of phone and then change it when you upgrade.
When buying a bike mount holder, you can also choose from slim/sleek models to more rugged mounts. The slimmer mounts are perfect for maintaining the streamlined aerodynamics when cycling on the road, while sturdier cases should protect your phone if you come off your bike while mountain biking - like a crash helmet for your iPhone 4.
To ensure that your phone will fit the model, you can buy a specific iPhone 4 holder or you can buy a universal bike mount which fit most phone models.
