JXFUKALRear Bike Rack Bag with Rain Cover, 7L/9L/10L/12L Waterproof Bicycle Ebike Saddle Bag Cycling Pannier Trunk Carrier with Reflector & Adjustable Cord for Commuter Travel Outdoor

Well madeAmple storage for lock, charger, tools, air inflator etc

I bought this to use on my Lectric XP ebike to carry spare tubes and my bike tools. It works great for both. It's pretty durable and it has a lot of room for storage. The Velcro straps were easy to attach to my book carrier and they're holding up really well. I would still recommend that you also wrap some bungee cords around it for some extra secureness.

This is a compact rear bike bag for your rack. I bought the 7l one, which is shorter (~12") than many trunk bags (~15"), but it was just the size I needed. Two hook'n' loop straps hold it securely in place and due to the nature of my rack, it isn't sliding forward or back even though there are no straps at the front. There's no form to the sidewalls, so it will collapse down unless full. The lid has a zipper pocket that opens wide enough to easily accept a large cell phone without difficulty. The zipper around the top of the bag doesn't reach all the way to the corners, so it doesn't stay open on it's own. I found that annoying. Both zippers are of the sealed style to deflect more water. It also includes an elastic cover; time will tell if that is sufficient to keep it from blowing away. And elastic cord on the lid will hold down a jacket or water bottle. There are a few steps on the side that are reflective to add to your profile at night.

It's a great bag overall. But it's not rigid which can make putting some items in it difficult- I put my iPad on the 'floor' of it. It was the perfect size for it but I had to hold it open to get it in. Only a minor inconvenience but one I didn't want to deal with.

This strapped on the back of my ebike's back platform, and it works great. It can't fit all that much, but I don't often need much with me. The velcro holds on securely, and the bungee cord type material on the top is nice to secure things, too. Good value for the money.

I was looking for something to replace the 'trunk' pack I had previously for something to carry my lock, an extra tube, and a few tools. This does the job perfectly. With the D rings I can synch it tight to the rack. It seems to be well made, butI'll have to see how long the zippers hold up as they are what I would call 'light duty'. This seems fine for the money...you get what you pay for.

Compact, fits well on rear cargo rack, insulated, velcro straps really secure it to cargo rack. Sturdy zippers, not bulky

Perfect for my e-bike. Perfect size, easy to install and very well made. Would definitely buy again.
