This Phone Mount with USB Charge port is the perfect way to power & mount your phone on your bike. Simply attach the mount to a 22-32mm round handlebar, connect the mount to your battery, red to positive (+) and black to negative (-), then power up the USB charge port. If your bike doesn’t have round bars, there is a mirror mount adapter (See Photo). Comes with a USB cable (Micro USB, Lighting, and USB-C) and includes an ON/OFF switch. Pair your phone to your bike coms and you’ll have “turn by turn” navigation and be listening to your favourite tunes as you rip down the road! Before securing the mount, check it isn't going to come into contact with anything on full lock.
