With security and safety often a concern, Nomatic has come up with an awesome bike backpack that thinks it is Fort Knox. Our premium pick is at the top end of our best cycling backpack budget, but you get a whole lot of security for your dollar. It does have the look of a small carry-on and will expand from 20L to 34L when you need it too, but it also fits neatly on your back thanks to its innovative strap system.
To keep your laptop and personal belongings safe as you ride you get lockable external zippers as well as a hidden RDIF blocking pocket on the back of the bag for your cards and smartphone. Add reflective ink and you will also be safe and visible at night. Made from water-resistant 500D tarpaulin fabric, you also get two water bottle pockets and plenty of extra pocket space for your smaller items. And at less than four pounds in weight, this is a super backpack for your cycling commute.
