Review: Good budget bag - The bag is well made and comes with a rain cover. It’s a good bag for the price but is a bit small if you want to store your helmet or something in there but it has decent space for smaller items. Stitching is perfect and strong and the zips are decent although I have had issues with one of the zips not moving and don’t want to force it in fear of breaking it. Over all will be a good starter bag and would serve light loads great.
Review: Finally, a cheaply priced bag but with VERY good build quality - It's very light weight, not bulky and is very solid and stable (no more saddle bag flapping around and hitting the wheel). It's detachable and easy to take off/put on due to the velcro. It has a strap (it's inside the bag itself when you buy it incase you feel like it's missing) Very customisable storage choices. You put it ontop of the rack like normal, the side pockets open and extend to become side bags for even more storage or keep them rolled up if you don't need it. A huge main storage section with an optional divider and about 20 other pockets. It's quite tall so it will block any rear lights on your seat post, but it has an area at the back of the bag where you can clip lights to. Honestly it's a 9/10. The only improvement I would make is for the velcro to be detachable, so that it can be left attached to the frame and I can take the bag straight off.

## Features

- ✅ EXPANDABLE SPACE: Inside the trunk bag, there is a removable board with that you could adjust the inner space. With the two side package expandable, the capacity of the seat bag is up to 12L that allows you to put more articles.
- ✅ STABLE & WEAR RESISTANCE: Thanks to the thicken foam pad on the bottom and side of the rear seat bag, the stability comes to high level. And the quality polyester material offers great wear resistance.
- ✅ MUTIPLE CARRY WAYS: With the hook and loop straps and buckles, you could fasten the luggage package to the bike rear seat easily. While you want to use the bag as a commuter bag, you attach the adjustable shoulder strap to the bag.

- ✅ NIGHT SAFETY: The reflective strips on the side make your bike visible during night cycling. Besides, you could attach a taillight to the pothook on the back to remind the drivers of your bike. 【ATTENTION】If you have any problems about our products, pls feel free to contact us, we will try our best to help you.

## Questions & Answers

**Q: How long are the bottom straps and how do they secure? Are they long enough to go round an e-bike battery fitted underneath the carrier, or just the ?**
A: Mmmm, they are only approx. 30cm long. I doubt it to be honest

**Q: How much weight can it carry?**
A: Difficult to say precisely. 5 Kilos or so I'd say. What is important I think is the distribution of weight. If it's all over to one side then the bag is liable to start leaning. It is semi-rigid, but there is a limit to how much it can take before it starts losing its shape.

**Q: Can fit a full size helmet ?**
A: Hi, thank you for contacting ROCKBROS, this bike pannier bag's dimension is 43.79 x 30.3 x 17.6 cm, i think it couldn't fit a full size helmet. You can have a look others bike pannier bag in our stores. Thank you.

**Q: Could you fit a helmet inside?**
A: Hi, it might be a little cramped for this pannier bag to put a helmet. Thanks.
