The new Bosch motor is smaller, lighter, more efficient, and simply better: it provides a more natural riding feel when you pedal and doesn't hold you back when you don't; Trek's Removable Integrated Battery System (RIB) looks good and is user-friendly: the battery is completely integrated into the frame, well protected, easily removable without tools, and has space for a bottle cage; The Kiox controller with color display provides you with all important ride 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 while riding so it's not in the way on descents. Additionally, it makes dismounting easier.
