## 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.
