Your smartphone can be attached to the handlebar thanks to a smartphone bike mount. A lot of different brands are selling such mounts. We personally love the ones from the brand Quad Lock.

We sell iPhone Quad Lock cases directly at checkout when purchasing a bike or on our webshop.

If you have an Android, don't hesitate to have a look at Quad Lock's website (QuadLock USA) . You could use a specific case for your phone or the universal fit case, this way you can add a mounting sticker to your current case as shown here.

Such a mount is not required to be able to use the bike though. Once the bike is unlocked, you can simply leave your phone in your bag and ride.

It is not necessary to make use of the wireless charging feature on the C4 (ST), you can switch it off through your app.
