About the Product

ROCKBROS 9L Hard Shell Bike Rack Bag Waterproof - 9L

The ROCKBROS Hard Shell Bike Trunk Bag offers 9 liters of durable, weather-resistant storage designed for rear rack mounting. Its rigid shell protects your gear from impact and the elements, while multiple compartments provide organized space for tools, personal items, and cycling accessories. Easy to attach and remove, this bag enhances your bike’s carrying capacity without compromising stability, making it an essential accessory for long rides and daily commuting. Engineered for cyclists seeking reliable storage with quick access and robust protection.

Features

  • Spacious 9L Capacity for Daily and Long-Distance Rides
    Measuring 13.2 x 7.9 x 8.65 inches (L x W x H), this bike trunk bag offers generous storage with two internal mesh pockets for neatly organizing items like a mini pump, repair tools, cable lock, or a lightweight jacket. The top elastic bungee cord provides additional space for gloves or extra layers—ideal for longer trips, commutes, or grocery runs.
  • Rigid and Fully Waterproof Construction
    Crafted with a reinforced hard shell polyester body and PU-coated surface, this hard shell bike bag is both lightweight and impact-resistant, protecting your belongings from rain, dust, and road debris. The double waterproof zippers and included rain cover ensure your gear stays dry even when the weather turns unpredictable.
  • Quick, Tool-Free Mounting System
    Featuring four adjustable Velcro straps, this bike rear rack bag can be mounted securely within seconds—no tools needed. The stable attachment prevents sliding or contact with the wheel, ensuring a safer ride. Its universal fit makes it compatible with most mountain bikes, road bikes, hybrid bikes, e-bikes, and gravel bikes.
  • Versatile Off-Bike Use for Everyday Life
    More than just a cycling bag, it easily transforms into a shoulder bag or handbag with the included strap and side hooks. Whether you’re commuting to work, heading out for a picnic, or traveling outdoors, this multifunctional bike rack bag fits seamlessly into your active lifestyle.
  • Enhanced Visibility for Night Safety
    The reflective strips and ROCKBROS logo increase visibility during low-light conditions, while the taillight hook provides a secure spot to attach your light—keeping you seen and safe on night rides.
