The Zeitgeist bike bag is a large and versatile bike bag that can be used as a handlebar bag or a saddle bag. It is designed for daily bike commuting, long day rides and bikepacking trips. The Zeitgeist bike bag is best suited for any bicycle and e-bike that has flat handlebars or dropbars that are wider than 44cm. We recommend using a front rack or support if you have less than 11" (28cm) of clearance from the handlebars to the tire. Externally routed hydraulic cables most commonly found on e-bikes, may interfere with the Zeitgeist bike bag.
