Integrated fixing system: The perfect bicycle accessory, especially for e-bike riders as it has an integrated BELT FIXING SYSTEM for securing the charger and stopping it sliding around. Comfortable to wear: The cycling backpack comes with an AIR PAD SYSTEM, which guarantees perfect ventilation of the back and therefore ensures incredible comfort even when worn for longer periods. Practical: Another feature of the EVOC backpack is the helmet holder on the outside for carrying XC/DH helmets. It also has some well placed pockets on the comfortable waist straps. Intelligent storage: plenty of room for your bicycle accessories. The control display pocket is integrated into the backpack, which allows for secure storage but also provides quick and easy access.
