This case is large and solidly built. It has two nice side pockets that are zippered. The bottle holder at the rear is very convenient and my water bottle is nicely secured. The velcro straps that secure it to my bike are quite secure with one caveat, the velcro straps that are on the front of the trunck are not very long and don't really reach the frame very well, so I separately use a bungee cord wrapped around my seat post and attached to the rear of the trunk to fully secure it. I'm not even sure I need this and still give it 5 stars.

It can handle a lot of stuff and travels well when empty.

A lot of thought went in to the design of this bag. It fits my needs perfectly. It sits on the back of my Radpower hike that I take into the woods for wildlife photography.With the expandable option, i can actually get my Nikon Z8 and 500mm lens in the top compartment. The rain cover is large enough to cover the bag AND the bike seat.The drop down panniers, while smaller, are big enough to carry what I need them to on the rare occasion I they are needed.Quality construction at a great price. Buy it!

Holds everything I need to have along on a bike ride. I like that it has a water bottle hold area as then no need to mount a frame bottle holder where not desired on my e-bike.

I’ve had this product for less than two months and one of the straps to attach to the bike is already broken. The quality of this carrier is terrible! If I could give this 0 starts I would. Not just because of the terrible quality, but because the customer support is a total scam! I submitted a return through Amazon and it tells me to contact Rockbros directly. I contacted them and they told me they were sending my issues to Amazon to help me. Basically a shady corcle to get out of taking care of the customer. Upon further research this company is based out of china and has no US customer support. Do not buy from this company!!

This small bag holds a log of gear. The fold down side saddle bags are great when you need extra room. It’s rugged. Great product.

This carrier is very versatile and will hold all of my bike repair gear and have room to store my jacket when I take it off. Like the zipper pockets so if I do not need them, they are zipped up out of the way.

Very nicely made, holds my binoculars and SLR camera, and adds lots of nighttime reflectivity.
