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 fully integrated into the frame, well protected, easy to remove without tools, and has 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 seatpost allows you to lower the saddle while riding, so it's not in the way on descents. Additionally, this makes dismounting easier.;
