Product Overview

I recently had the pleasure of testing out the ROCKBROS Bike Trunk Bag Bicycle Rack Rear Carrier Bag. After using it for a few rides I have to say Im impressed with its rugged construction and versatile features.

The bag is made from high quality polyester material, making it strong and durable enough to handle whatever you throw at it. The material is also waterproof, so you dont have to worry about your items getting wet on rainy days. The main compartment of the bag is 13 liters in capacity, giving you plenty of room to store all your essentials while riding. It also has a removable board inside for extra organization. On either side of the main compartment are fold out pockets that add additional capacity for those who need more space. To ensure your items stay put during a bumpy ride, there is a thick foam pad along the bottom and sides of the bag that helps keep its shape as well as provide protection for your items.

One of my favorite features on this trunk bag is its mounting system. It comes with two straps on the front for securing it to your rack, two long straps going across the rack, and two fixed buckles that keep everything in place. Ive tested it on several different kinds of racks including fat bikes and e bikes and each time it has stayed securely attached without any issues. For added safety at night there are reflective straps on the bag which makes you more visible to other riders or drivers on the road.

Overall this bike trunk bag from ROCKBROS is an excellent choice for cyclists looking for a reliable way to carry their gear around with them while riding. Whether youre commuting to work or going out for a day ride, this bag will provide ample storage space while staying securely in place. I would highly recommend this product to anyone looking for a durable and versatile trunk bag for their bike!
