Topeak trunkbag

Dispatch had a malfunction yellow clip that holds on to the bike rack as I was riding my bike on a long distant ride it came undone and my bag got ruined

Quality product. Delighted

I purchased the Top Peak bag for my first Aventon bike. It is definitely a well made product snd I am getting the use out of it I had hoped for.

Deserves 10 stars.

Oh how I love my bag. Be forewarned you need the Topeak rack, this slides right on and locks in place. Push the yellow button to release. My daughter has the 350 bike and did not want to replace her rack so I went hunting for something different for her. Nothing comes close to this Topeak bag. It Never shifts despite being overloaded. It has 2 large drop down bags that hold a ton of stuff and never rip, laptops, grocery, not a bulge in the zipper or a dent in the fabric. The only reason you buy a trunk bag is to carry stuff so save yourself some time and trouble and buy this bag. I tried, I never found anything else as good. My only complaint is there is no way to add a lock to prevent someone from stealing the bag. It is simple to take on/off so i bring it inside while I am at work. The stretch cord on top is big enough to hold a helmet. It has a built in cup holder at the back end with a cinch adjust. There is an inside pocket on the flip open top and a divider for the main cargo space (I never use this). The bag is expandable (I use that a lot) adding 2" to the height. I have had my bag 3 years and it is still in great condition and I expect it will still be great after 10 years. I ride to work seasonally, 10-15 months and do shopping runs frequently. The rack it works with is very sturdy.

MTX Trunk bag review

I love the bag but was very very disappointed that for $80 it did NOT come with the bracket required to mount to the Aventon bike rack.
