Much like its counterpart, the Energy Bag 2 from Deuter is made with mountain biking and convenience in mind. The top tube bag is ideal for keeping your mobile phone, money, and keys within easy reach, whilst the built-in transparent window allows you to see your phone screen whilst on the move. Three hook and loop fasteners keep the Energy Bag attached and in place on your bicycle within easy reach of the handlebars, so you won’t have to stretch too far to access your necessary items.
