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