Smartphones can really enhance your riding experience. If setup correctly, they’ll assist you with bike navigation and will collect a bunch of metrics like speed and distance – and if you want, you can even track your ride. Smartphones are not just great for navigation and data, I like having them on my handlebars so that I can briefly catch my incoming calls and messages while I ride.

My Favoutite Smartphone Cases for Cycling

Quadlock Case + Bike Mount
I’ve used the Quadlock for years now and am still super happy with the product. The case is slim, the mount is highly effective and the system is light. Here’s my Quadlock Review which resulted in a perfect score.

Quadlock Universal Mount
If you find the Quadlock case too bulky, you use an Android phone, or you already have a nice waterproof (and shockproof) case – check out the Universal Mount by Quadlock. This product employs an ultra-strong adhesive sticker which will allow you to mate your favourite case with the Quadlock Bike Mount.

A Few Things To Think About Before Buying A Bike Smartphone Case

Smartphone Cases for Cycling
Some cases are designed to stay permanently onto the smartphone, while others are designed to be used just for the purpose of going for a bike ride.

Bike Smartphone Mounts
The following cases mount in different ways: some onto the stem, some onto the handlebar, some can mount in front of the stem and others will come directly off headset top cap.

Waterproofness
Some cases are 100% waterproof which can be a good idea because rain can start to fall pretty quickly. A waterproof mount also means you won’t need to stop and put your phone in a safe place. The drybag design isn’t the most user-friendly because it blocks the speakers and microphone from your phone. If you want to go waterproof, I’d suggest a hardcase with an enclosure.
