Long-Range Battery

Why You'll Love It

• For an e-MTB, the full-suspension setup is a revolutionary feature that lets you take on the roughest terrain while maximizing the potential of the Bosch pedal-assist system.
  The 625Wh battery provides more power, allowing you to stay on the bike longer for maximum fun.
• Trek's excellent RIB (Removable Integrated Battery) system is extremely intuitive: the battery is fully concealed and protected inside the frame and can be easily removed without tools. Additionally, you can still install a bottle cage, even on this full-suspension e-MTB.
• The Purion controller includes Walk Assist and eMTB modes, which automatically deliver the right amount of power depending on the terrain.
• The Powerfly FS frame has a curved top tube that makes it easier to touch the ground with your feet. The Smart Wheel Size philosophy allows the use of the fastest wheel size based on the frame size: 29" wheels on larger frames and 27.5" wheels on smaller frames.
