This bicycle trunk is easy to attach to just about any style of rear bicycle rack. A few straps with velcro hold it securely in place. I like that the panniers stowaway when not needed

It provides adequate storage for essential items for a trip, or short Commute.

I used it for trail riding over some very rough trail and it stayed secure and items inside were properly protected.

This bag is pretty good, I like the portability of it. The issues I have is the zipper on one of the side panels broke within a couple weeks, JustBikeBags was great about it and sent a new bag immediately. My rack has a solid bottom, so the velcro on the bottom does not do anything, but the front ones are perfect and keep the bag in pretty good place. The interior space in the main compartment is a little smaller than I had hoped, but it is sufficient for a change of cloths. Overall I do actually really like the bag aside from these minor setbacks. It is a sleek looking bag and seems to be otherwise durable. I have not had any issues other than the zipper.

This trunk appears and feels very high quality. Does not sit too high and is streamlined for my particular bike. The light on my seat is easily seen above the trunk (see photos). Plenty of room for my gear and groceries using the panniers. I am amazed how light it is considering how solid and sturdy it is. It took a few minutes to mount it but afterwards it was secure and I am confident it will not slip or fall. I do not use my bike off road very often but the Velcro seems strong and there is no wobbling. All-in-all even though this wasn't cheap (you get what you pay for) I expect that this trunk will last for years to come Plus it matches my bike and seat perfectly..
