The HandleBand is a new product from NiteIze that attaches a smart phone to bike handlebars, but also has other functions. For example it can be used to attach a light or pump to a bike, or to any other round tube that's roughly the diameter of a handlebar, such as a jog stroller or shopping cart. It also has a built-in bottle opener.
The HandleBand is made of silicone rubber and is available in black or white.
