Big Mouth Pannier

Big Mouth Pannier

Easy-access grocery-getting pannier

The Big Mouth Pannier is the newest and biggest addition to Tern’s ecosystem of bags that help you carry a load on your bike. The Big Mouth pannier bag holds up to 6.1 gal so it’s perfect for grocery runs or daily commuting. Thanks to the wide cinch-top opening you can easily organize, load, and secure your cargo. It opens so wide, in fact, you can easily drop a basketball or watermelon inside.

The Big Mouth hangs on the side of your rear pannier rack with robust Ortlieb pannier hooks, so you can expect years of reliable operation. Finally, we designed the Big Mouth so it can fold flat when you aren’t using it—cinch it flat on the side of your bike for a discreet and narrow profile.
