If you need a secure way to mount and store a battery on your electric bike, it doesn’t get much better than the Topeak MTX trunkbag EX. This bag is constructed with rigid molded panels and flexible 600 denier fabric, which provides the rigidity and water-resistance to keep your battery fully protected.

The MTX trunkbag EX is compatible with all of our 250 Series E-Bike Kits, and will fit Leeds’s PBJ, 10k, 10k+, 30k, 30k+, Ultra, and Ultra+ batteries.


This bag is compatible with QuickTrack, a useful rear rack system that allows you to slide compatible bags on and off, which are kept in place with an easy-to-use locking mechanism. With the included shoulder strap and carry handle, it is very easy to take your battery back and forth from the bike to the charger. Keep in mind that MTX bags are only compatible with MTX racks.

The large capacity main compartment is insulated and features molded EVA foam sides, tops, and bottoms for superior protection. This bag also has 2 mesh side pockets, and 3M reflective trim for improved visibility at night, and elastic top bungees allow you to attach additional objects if desired.
