Your smartphone is a natural partner for your bike, especially if you're serious about commuting or training — most phones come with a flashlight, and apps for training, navigating, and video. The Handleband ($25) is a flexible smartphone mount for your bike that accommodates a range of devices, gives you access to your phone, and allows you to position it within view or for use as a headlight (it even has a built-in bottle opener). It's made from aluminum and premium silicone, so it's durable enough to handle just about any terrain, and flexible enough so you can easily remove it.

Available in range of colors and fabrics, this seat is easy to clean in case the Gs start to get to the little guy.
