  • Glad I Bought It
Color: black-1
This well made bag is light weight and easy to install behind the bike seat. There's plenty of room for storage and the zipper works well and seals the bag from the elements. The bag replaced an older heavy basket that came with the bike and looks a lot better. I chose this bag because of the looks, and price; comparing it to other similar items that were $100 or more. Glad I bought it! ... show more

  • Great addition to my E-bike
Color: black-1
Holds well, is sturdy, is spacious, and has utility. I can fit like 5+ drinks in it, plus my DJI mic, charger, camera, and power bank. It holds in place going 50mph and on bumps, coming off curbs, etc. versatile I'd say. It's also really stylish, I get compliments often about this bike and I'm sure this adds to it. Just matches really well I think. The price isn't bad on this either. It is easy to put on with it's straps, like I said, stays in place. Easy to remove and can even be used as a travel bad or gym bag with it's straps and handle. ... show more
