## Questions & Answers

**Q: how easy are the rear side bags to take in and out?**
A: They are extremely easy to take out and put back in.. 
I own two of these bags.

**Q: Will this work on foldable ebike (EG 250)- will unfolded panniers be too long? Rack long enough?**
A: I'm not familiar with the EG 250 foldable ebike, but I'll give you the dimensions of the truck bag.The main truck bag compartment measures 12"×6"×6" inside. The expandable panniers measures 15"×10"×2" when open. The panniers hang down 11" from the of the top base plate of the carrier rack. 
The bag is well made, spacious, and extremely water resistant when all compartments are closed up. I have three of these bags. The other two of these bags have different brand names and use nylon canvas outer shells with ordinary sippers construction and materials. Those other bags are not as water resistant as this RockBros version. 

I'm pleased with not only the RockBros poly outer, but I'm equally pleased with the materials and construction of the moisture repellent sippers RockBros truck bag.
 
I highly recommend this trunk bag, it is worth extra expense over all of the others for the ability to shed rain water.
I hope this helps.

**Q: Is the bottom hard?  i want to attach a mik adapter plate to use with my mik rack.**
A: It’s stiff… but I don’t know that I would call it “hard” it flexes and it’s not rigid. It would probably work ok with a Rack mount system, although I am not familiar with Mik’s set up.

**Q: Reviewers indicate some received a rain cover. does this come bag come w rain cover?**
A: Yes it did come with a rain cover
