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 if you don't; Trek's removable integrated battery (RIB - Removable Integrated Battery) looks good and is user-friendly: it is completely integrated into the frame for optimal protection, can be easily removed without tools, and even provides space for a 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 features an integrated anti-theft function; The Vario seat post allows you to lower the saddle during the ride so that it is not in the way on descents.
