Very similar to Topeak's $115 EXP trunk bag, Aventon's trunk bag features a spacious main compartment and expandable pannier side panels, allowing you to carry even more gear on your rides.

The bag features a built in carrying handle as well as a removable shoulder strap.

Other features include an integrated water bottle holder, reflective striping for enhanced visibility and a mount to clip on a flashing rear light.

Gear capacity: 25 liters.

Attaches with Velcro straps and fits almost all rear mounted bicycle racks.
