Perfect E-bike controller bag!
5 Stars
Perfect E-bike controller bag!
I bought this specifically hoping it would make a good bag for an ebike controller. I bought a front hub motor wheel kit to convert my bike to electric. It is the "old school" kit with a big controller with lots of wires for plugging in the various components. If you know what I am talking about you realize those are hard to contain cleanly just because the wires are numerous. This bag worked out perfectly - the controller and all the wires fit in nicely and best of all should you need to replace a component you just unzip the bag, find the wire you need and swap out the component (throttle, PAS etc.).The one thing I was not crazy about was the mounting straps they provided but a 1" Velcro One Wrap strap allows you to perfectly customize your length and gives you a very clean install. When I first tried out my ride I noticed the controller was bouncing a bit in the bag and rattling against the stiff bottom. I put some chunks of foam packing material under the controller and added a couple of cinch straps around the bag for extra security and now the setup works perfectly, holds everything inside cleanly and gave me a really clean looking install overall. The bag is nice quality and should last as long as I have the bike. I can't vouch for the waterproof aspect but I never feel great about having an ebike out in the rain anyway so unless I get caught in a surprise rainstorm I'll never worry about that.100% perfect for my intended use here. 5 stars all the way except for the mounting straps but the Velcro One Wrap works far better anyway.

5.0 out of 5 stars Couldn't be happier with this frame bag - Perfect!
Reviewed in Australia on October 15, 2020
So, on a recent multi day trip I needed a frame bag... and quick.

After a lot's of reading, I settled on this Rockbros frame bag. The super cheap price, rigid nature of the bag and more importantly water proof feature really sold me - did I mention how cheap. Bag turned up in a few days too.

The smaller left hand side was great for thin items (battery, nutrition etc) and the larger right hand side perfect for tools, tube, arm warmers & rain jacket. Soooo easy to access too.

I also really liked the flexible nature of the multiple mounting straps.

If this bag was 4 times the price, I'd still be happy.

In a word - AWESOME!
