Designed with an expandable top section and two side panels that fold out into two full panniers, The Topeak Trunk Bag MTX DXP has a total capacity of 22.6 liters, making it the biggest MTX series bag that Topeak has ever made and perfect for bike packing and commuting. With several external pockets and elastic bungee cords, you can also access small essentials, like energy bars or petty cash quickly and easily. It even has a secure rear bottle holder for added water storage. Constructed from 600 denier polyester, it's also incredibly strong and weather-resistant too, so even in downpours, your essentials are kept safe and dry.  Unlike many rear rack bags and panniers which have a habit of obscuring rear lights, the Topeak Trunk Bag MTX DXP has a dedicated safety clip for your light, as well as reflective detailing for added visibility.

Great piece of kit

You don't even notice there when riding but it adsorbs the things you need to carry like some magic Santa sack. Merry cycling to all...

Easy to slide on rack and set up pannier bags

Easy to slide on rack and set up pannier bags. Happy with purchase. Delivery to New Zealand in busy pre Xmas period was spot on what was stated at purchase 😀

That's not my bag, baby!

The Topeak MTX DXP with pannier is their larger, expandable bag. The sides unzip into panniers and the main compartment also unzips to give it a little extra space on top. We've been using it for some tools and for beverages and snacks, it's a great bag baby! This unit easily slides into the rack track and locks into place. This IS my bag, YEAH BABY!

Topeak trunk bag

Really clever design. Fits my laptop and shirt shuttle with a space for my lunch box. 😄

The bee-knees of bike bags

This bike may not be the most beautiful but for utility, quality and expandability it is probably unsurpassed. In my first week commuting with the bag I have used the bag and one of the two flap out panniers and this has easily swallowed all my work kit with lots of space to spare. I have to lock up my e bike on the road in central London, so on the Monday morning and Friday evening the bag contained a Kryptonite New York M18 Lock inside and an ABUS 430/170HB Super Ultimate D-Lock on top of the bag with no problem. It is hard to fault the carrying opportunies of this bag attached to the correct Topeak rack. The one minor criticism of the bag I have is that it can be a little fiddly to thread it into its rail on the rack. This is helped by the application of some lithium grease. Once it is on the bag is easily and firmly locked in place without any rattles

a small village...

i have 5 bicycles with this bag on them. you can carry a small village with you. i especially love it when doing bike tours. it's an awesome product, been using them for a long time, pack up,fill er up and leave the world behind... ride on...


Bag has finally arrived, and very pleased with it.

Great Bag

I have really enjoyed this bag and it has performed well. I definitely would purchase another one!

Handy pannier

The Topeak Trunk Bag is great with my Trek Powerfly 4. No more sweaty back when riding to work with a back pack. The fold out sides are big enough to carry a full change of clothes, my RM Williams boots, towel and bathroom gear. Now I travel to rowing training then on to work with all my gear and no need for an extra back pack. I like the rail and lock system on the carrier frame as well. Highly recommended piece of kit.


Robust and easy to use. This will revolutionise my cycling holidays.
