  Trek's Removable Integrated Battery (RIB) system looks great and is super user-friendly: it fully hides the battery in the frame for protection, makes it easy remove the battery without tools and lets you mount a water bottle cage  
  This bike expands boundaries: the top-notch Bosch system is equally suited to commuting, recreation and a ridiculously fun time on the trails  
  The Purion controller has Walk Assist and an intelligent eMTB mode that automatically delivers the right amount of power based on your terrain  
  It's equipped with an external charging port for easy charging on or off the bike  
  You can boost your Powerfly’s utility by adding a rack and mudguards, plus built-in wiring lets you easily install lights powered by the motor
