Customer Reviews

Overall rating: 5.0 / 5 from 15 reviews.

I've been looking for a half frame bag that would fit around the battery in my medium Surly Grappler e-bike conversion and stumbled upon another Grappler owner who had your 5L bag. So I ordered the slightly smaller 4.2L bag and it fits like it was custom made for my situation! Nice materials and construction, very functional, and really changes the appearance of the bike. Thanks for making such a functional bag at such a great price!

It's a really nice bag, I ordered the 6.5L which is the largest size. However it's too large for my frame. I will be returning it and getting the next size down. The quality of the bag is great.
