So, we’re doing something a little bit different today by bringing you a review of something that’s not for hiking or camping! Nevertheless, it’s one of our favourite pieces of outdoor gear – the Topeak Backloader. It’s a bicycle bag – one that fits on your seat post, designed for people who don’t have – or don’t want to use – pannier bags. So, let’s dive in and take a look!
Overview & Specifications
One of the things that first attracted me to this bag is that it fits on the seat post of pretty much any bike. A simple thing, for sure, but this gives you the power to turn your everyday commuter into a touring bike! No more worrying about having the right mounts for pannier bags. In fact, no more worrying about pannier bags period.
Between this seat bag and a small backpack, you have more than enough room to take everything you need for a short and sweet overnight camping trip. That’s presuming that you’re going ultralight, of course.
The Topeak Backloader bag comes in 5, 10 or 15 litre versions. The one we have pictured here is the 15 litre, which weighs in at just 565 grams (~1lb 4 oz.). The outer bag is made of Polyethylene and Nylon and is ‘water-resistant’, rather than waterproof.
The Topeak Backloader comes with a handy internal dry bag, so you can be sure your gear stays dry inside. I would have recommended this approach when using the bag anyway, so it’s nice it defaults to that way of thinking. It’s better to have a removable dry bag inside that you can take in and out of the Backloader. This saves you from having to detach the whole Backloader every time you need to retrieve something.

I took this bag out on a recent trip to the countryside and managed to pack in a down jacket, sleeping bag, sleeping mat, some food,
The Topeak Backloader is slightly fiddly to attach to the seat post for the first time, as there are a few straps to reckon with. But it gets very easy after the first go. The most important thing is to cinch the bag up very tight, so you get plenty of clearance between the bag and your rear

It didn’t rain during my trip, so I can’t speak for the water

Topeak Backloader Verdict
The Topeak Backloader is a simple enough bag, but made really, really well. That aside, the thing that I really love about it is the sheer sense of freedom it allows and the different options it gives you for taking trips.
Going on a camping trip? The Backloader allows you to increase the range of places you can get to by taking your bike instead of walking.
Going on a bike tour? Then why not incorporate this in addition to – or instead of – pannier bags?
Need to borrow a friend’s bike to pick up some stuff across town? Then just grab your Backloader and get rolling!
There’s nothing like that feeling of waking up on a sunny day, slinging your bare essentials in a bag, and pedalling off to who knows where. And it feels like that’s exactly what the Topeak Backloader was designed for. It’s what I love about it the most. It’s designed to fit pretty much any bike and just lets you expand your options and your horizons.
