Using this Evoc E - Bike backpack is easy. First, pack your daily essentials in the different pockets and compartments. You can put your XC/DH helmet on the dedicated carrying part and store your sunglasses in the special compartment. If you need to extend your riding range, attach your charger or extra battery using the strap attachment system. Keep your control display in its separate compartment. When it comes to maintenance, clean the backpack regularly with a soft cloth and mild soap. Avoid using harsh chemicals that could damage the material. Also, make sure to dry it thoroughly before storing. Remember, the hydration bladder is not included, so if you want to use one, you'll need to buy it separately.
