- Rail Gen 4 features a pocket in the top tube, so you can easily upgrade to Bosch’s latest System Controller and Mini Remote if you’re craving a cleaner setup
- Treks 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 to remove the battery without tools, and lets you mount a water bottle cage
- Boschs smart system gives you all the same power and responsiveness with a Bluetooth-connected LED remote and eBike Flow app that puts even more control and customization at your fingertips
- The controller has Walk Assist and an intelligent e-MTB mode that automatically delivers the right amount of power based on your terrain
- The frame is extra-stout with a 34.9mm seat tube to accommodate more robust dropper posts, and an oversized head tube that works with burly e-MTB optimized forks for less flex and more precise steering
