Ride Ready Storage, No Matter the Distance
Whether you’re commuting through the city, tackling rugged trails, or going on a weekend bikepacking adventure, this expandable hard shell bike trunk bag is your reliable storage solution. Built for both casual cyclists and serious riders, it combines durability, flexibility, and sleek design to carry your essentials with confidence.
Durable by Design
Crafted with a robust hard shell exterior and a sleek carbon-patterned finish, this pannier bag isn’t just about good looks—it’s built to protect. Its rigid structure guards your gear against bumps, splashes, and unpredictable weather, ensuring everything inside stays safe and sound. Perfect for mountain bikers, touring cyclists, or weekend warriors who demand resilience on every ride.
Customizable Capacity
This trunk bag adapts to your needs on the go. Choose the compact 11L version for everyday rides or expand your storage from 17L up to an impressive 31L when the adventure calls for extra gear. Need more room for tools, snacks, or clothes? Just unzip and expand—it’s that easy.
Smart, Space-Saving Features
When you’re not using it, the bag’s foldable design makes storage hassle-free. Tuck it away neatly without wasting space in your garage or gear room. It’s a cyclist’s dream for practical, on-demand organization.
