The new Bosch motor is smaller, lighter, more efficient, and simply better: It provides a more natural riding feeling when you pedal and does not hold you back when you don't; Treks Removable Integrated Battery System (RIB) looks good and is user-friendly: The battery is completely integrated into the frame and thus well protected, can be easily removed without tools, and offers space for a bottle holder; The Kiox controller with color display provides you with all important riding data, connects via Bluetooth® to your compatible devices, and has an integrated anti-theft function; The dropper seatpost allows you to lower the saddle while riding so that it is not in the way during descents. Additionally, this makes getting off the bike easier.
