Topeak Backloader Seat Pack
BackLoader is a large capacity seat bag specially designed for bikepackers providing a streamlined way to carry gear without the need for a rear rack.

Mrs Moon This is very useful for long-distance bike trips. It's been a year since it's been used, but it's very sturdy, lightweight and practical.
Mr Westphal Perfect for getting away either over night or a few days. Pack offers ample space for bikepacking.
YorkshireCyclist Well made item, that is most definitely waterproof. I have tested this a number of times when I've got a proper soaking. I use it for taking a change of clothes to work. Easiest to load by rolling clothes and put heavy items closest to the seat post. Some reviewers say that it sways. I have noticed this only by looking for it when out of the saddle, i cannot notice otherwise. Possibily should have got the larger one, as sometimes find its not big enough so recommend that you order a bigger size than you initially thought!
Mr Yardy Great product - only used on test rides so far, but it looks to be exactly what I'll need for extended bike packing trips
Jess Good quality, sturdy and practical design, excellent value.
Mr Norman Excellent bag, well made, sturdy, waterproof. Survived London to Paris in the pouring rain.
John I wanted something quick to attach but fit securely for overnight stay/weekend away cycling when not using my panniers. This is a well made piece of kit. A bit bigger than I expected but as it compresses that is not an issues for me. it stays secure while riding. A very practical bit of kit that will get a lot of use.
anne Great purchase. Definitely what I was looking for. Sturdy and well made.
kidzor Product looks good with a very nice construction, fits well even on an aero seat post. Haven't gotten the chance to try it out, but I'm planing a trip soon. Pleased with it so far.
Mr BEVAN This was a panic purchase because my original saddle pack was too small and I was doing the 50/50 gravel dash a couple of days later. Anyway it was delivered the next day Its a well made bit of kit but the star of the pack is the internal stuff sack which you ram full and roll closed then bleed the air out of it, my sleeping bag literally dissapeared into a tiny packand then you put it into the seat pack. The seatpack swallowed my sleeping bag, tarp, groundsheet, bivi bag and a change of clothes, hell of a lot really with space left. Roll it up and tighten to the saddle and jobs a good un. Yes there is a little bit of "sway" when off road and climbing but its only to be expected. Bottom line this is a 5 star product
Dave So far so good, a bit of sway in the bag when pedaling hard but overall good value for money with cheap shipping
Christopher Used for a short trip so far, but no issues with set up, don't notice any swaying when riding. Soon get used the to different weight distribution on the bike. Seems well made and good value.
Graham I ordered the 15L Topeak Backloader seat pack as I was planning to cycle around Kent with an overnight stay in a hotel. The item is well made and attaches securely to the seat post and saddle with straps to stop it moving too much. It held enough for the overnight stay including minor toiletries, a change of cycling gear, some shorts, a polo shirt and a thinsulate top - there was still some room left. All the items were placed in the waterproor inner. During the trip I did cycle through a shower or two which didn't get through the external material so everything inside was bone dry. There were some envious looks from within the group and I would certainly recommend the item - it did a great job.
Mr O'Sullivan Very pleased with the Topeak backloader. Cavernous space and solid,doesn't rock about. I hadn't adjusted it properly so it rubbed on the rear wheel but after pulling the straps everything was fine. I've used two cable ties to also pull it slightly tighter onto the saddle rails for height. Great price from Merlin cycles as well.
Martin Great quality, easy to fit and you can fit a surprising amount in
Mr Wishart Bought this along with the Topeak Frontloader Handlebar bag prior to my first bike-packing experience and I cannot fault it. Value for money for sure. It's simple to use, feels quite secure (was worried about wobble but it felt good and secure) The supplied internal drybag is a great feature and the air release valve was the envy of the group (some guys had much more expensive branded items without this feature!) Have recommended to anyone that will listen to me!
Mr Allsop Absolutely 10/10 product. Durable, well made, lightweight & spacious. Just what I was looking for. Doesn`t move around too much and better than other products like this I`ve used before
JLC Great bag and the internal dry bag is really useful during stops.
Mr Horwood Previously purchased Topeak front pack and now am delighted with the seat pack....completes my storage bike packing needs....excellent.
Mr CANIMOGLU 6 L, I bought it for one day long distance tours...Product photo is different...New series; colors more beautiful, black logo and label...High quality and inner bag is perfect....Good discount...Thanks
Matt I'm very impressed with this seat pack, yet to use it on a long ride but the quality of the outer bag and inner dry bag seem great. Well thought out design and excellent value for money.
Carmelo Wonderful product. Very sturdy. Absolutely the best I ever tried
Mr Peters Really clever way of loading a mountain bike for cross country touring. No need for back rack. Merlin cycles provide excellent service and fast delivery. Thank you
Mr Renshaw Bought two of Topeak backloaders for our trips for next year on our fat bikes .. plenty of room for storage and better quality than others at an affordable price..
Tim A brilliant piece of kit, fully waterproof and well built, so far its stood up well in use.
Barrett Clearly a good quality item made from robust materials. Easy to mount, but did have some issues with it rubbing against my back wheel. I have a 29er so suspect the wheel size may be why this happened and I ended up having to put my saddle higher to compensate. Was able to pack a good amount of gear into the pack though and loved the air release valve.
Kim Really good saddle bag, plenty of room for long day out if you don't want to stop at a cafe and get out into quiet country roads.
Mr Beratto de Santana Great bag 15l, did 200 miles in the rain. If the bag is less than a third full it sways from side to side because the straps can't compress any further. Except for that, very good bag
samuel I bought because my seatpost is short, and therefore I wanted just one front strap. It was nicely stable in use. It did suffer some strap slippage compare to my wife's Ortlieb, but not annoyingly so and it was considerably cheaper
Miss Wright This seat pack has been wonderful to use. I've taken it on a 2 day, 3 night journey of 80 and 90 miles on each day and it's held up fantastically. On the second day we had very heavy rain and were out cycling for about 8 hours. The dry bag of course kept the stuff inside completely dry, but the rest of the bag also kept everything reasonably dry. My purse and some other bits were only slightly damp despite the rain, so I was impressed with that. I recommend the 15L version since you can pack it down as much as you like if you have less stuff, but it gives you the flexibility if you want to bring more/ your friend didn't plan well enough / you see something you want to buy. Penduluming was minimum when you pack sensibly; i.e. heavy stuff close to the seat post and really tighten the straps. Wasn't an issue once I got the hang of it. I don't have a tourer bike, just a regular roadie but this worked incredibly well for that. I'd say if you want to get into longer trips but don't want to invest in a proper tourer, panniers et al then this is a great choice. It was really nice not having to take a rucksack. The straps on the top were really useful as I brought along a pair of trainers that I didn't want to squish into the main bag (though they became victim to aforementioned rain). As I've only been on one proper trip with it I can't say anything for durability yet. It looks well made and I've had my other topeak saddle bag for years now, so I am not too worried.
Mr Jaworski Huge bag - very well made I love it. I think for everyday riding I would go for the 10L though because the 15L is just massive! I have had several other saddle bags and they were a pain to install and ride with but this bag is super secure and I love the waterproof lining bag it comes with.
Mr Moran Useful, practical bag, the seat bag and air release valve make this a good buy
Mr Randles Excellent product. Did exactly what I needed it to do. Very stable in position behind the saddle and very easy to pack.
Mr T J Hansen I love my new Topeak Backloader Seat Pack 15L, really high quality and easy to fit onto the seat post. I live in Denmark and ordered it Monday and got it delivered Thursday, really good job merlincycles :o)
Calle Roomy, sturdy, mounts perfectly. Had it filled with clothes, shoes, food, tools on a solo 220km ride on my aero carbon bike - no problem at all.
Defy Rider Great seat pack with little sway when packed with a tent and camping mat (4.2kg total). It has mounting points underneath that allow you to attach a rear light then you roll the bag up.
Jari 15 litres version is a beast of a bag, but not in a bad sense. I use this to reduce weight of my backpack on commutes. The bag has a lot of external attachment spots for the times you need to overpack. Take care when packing, heavy stuff should go closest to the bike frame otherwise the bag will awing around whe pedalling hard. Long term durability remains to be seen as I've just recently bought mine.
michael Really pleased with the Topeak Backloader. High quality and easy to fit onto the seat post. Surprised just how much I can get into the bag as well. When cycling (road bike) The bag does naturally swing somewhat when climbing, but not as much as I thought it would. Really happy with this.
andyh Well designed, well made, especially for the money! Very unobtrusive if loaded and tightened up properly, have only used it up to about two thirds it's full capacity so far and it has been extremely stable and looks and feels like it's gonna last a fair few years! Also good that you can leave it on bike and just pull out the dry bag with all your gear in.
Linda This will be perfect. Just the right size and strong enough too.
Mr CANDAMO Love it. Now I don't need a escort car because everything I need for a long ride fits in the seat pack
Ben Great product. Great size for carrying my tent, trangia set and clothes. Inner bag is fantastic too, really happy with this! No saddle movement too! great service from Merlin.
Mr PARK I bought this back loader seat pack for my bike trip with my son this spring. There are some products made by other manufacturers, but I bought Topeak 16L for three reasons. It has built-in air release buttons to enable compression, reasonably priced, and favorable reviews from existing buyers around me. I have not tried it yet and I can not make these evaluations for the product at this time. Nevertheless, it is surely better than carrying heavy backpacks on our shoulders in long-distance bicycle trips.
Tony Bought this saddle pack as I often purchase Topeak products for their great design and quality. I am extremely happy with the Backloader seat pack. It has very simple and secure fittings, the quality of the materials is very good and looks robust and it's great value for money compared with other makes. I will continue to buy Topeak products in the future for all these reasons.
neil Just starting my bikepacking adventures and this seat bag was perfect for my kit fits securely on the post and can be tensioned with ease, also a good price compared to other brands
Daniel Love this. Not using backpack and just use this is very liberating. I got the 15L and it's just great for carrying change of clothes, lunch, etc.
Gavin Terrific kit, holds much more than I thought. Quick and easy to assemble and feels really well made.
Albert Well made and very useful for any occasion. Way better than having a back pack on a long ride.
Powerdive Excellent item. Used this weekend for a ride with an overnight stop. Good mounting system. Pretty stable. Limited impact on handling and aero. Will probably buy more of this system.
PR Perfect size for work shoes & a bit of lunch. Fixing is good and should be sturdy enough for some lighter bike packing when needed. Much cheaper than the alternatives, especially with the included dry bag.
M Good quality product as expected from Topeak. Easy to fit, stores quite a lot (could probably get a pair of shoes and change of clothes in here, as well as tools, phone, wallet. Am not convinced this is much better than Chichester versions that cost half the price. For touring would advise the 10L although the 6L looks more balanced.
williams Bought the 10l version really happy with the main bag plenty of room for my needs. The dry bag however if used does leave a lot of empty space in the bag it's a shame because I like the design of the dry bag with the airport valve on. If you don't fill these type of saddle bags up that's when you get wobble issues. I've since used it with my own dry bag and without packed it down tight and no wobble issues at all.
L2R24 First off, this item was a great price on Merlin's website. The item itself is very well made and, at 6 litres, is the perfect size for what I needed, but also can be easily adjusted with the cinch straps. Fixing is secure and the included dry bag has a novel "air dump" valve to help keep the size down when you use the roll-top enclosure. If its dry you can leave the dry bag at home to keep the weight down. Brilliant, versatile bit of kit at a cracking price. Recommended.
