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 slow you down 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, easy to remove without tools, and offers space for a water bottle holder. The Kiox controller with a color display provides you with all the important riding data, connects via Bluetooth® to your compatible devices, and has an integrated theft protection function. The dropper seat post allows you to lower the saddle while riding so it's not in the way on descents. It also makes getting off the bike easier.
