I bought this for my motorcycle. This is a custom bike and I ride 80 to 90 mph. What I like is that it fits my handlebars because they are quite big and you have two different handlebar sizes. They also give you multiple sizes to fit your phone. Not only is it great to get the extra parts, they are pretty darn strong. And then there's the fact that you know your phone is safe or not off the bike, especially when our phones are $800-$1,200.
