Your Electrified smart module is powered by the bike's integrated battery. The battery will intelligently route power where it's needed most – to the motor when you're riding, and to the smart module when it's not. 


If your Electrified has been powered down for a while, the smart module may need to be charged manually. 


To do this, you'll need: 


A micro USB cable 


A power source (phone charger, powerbank, or even a laptop) 


Connect the micro USB cable to the power source. Plug the micro USB cable into your Electrified S USB port (on the bottom of the top tube, below the display). After a little while, the smart unit will activate – you're good to go!
