Looks like there's a new player in town, and this one is American. Anyone have any info or experience with the new Electric Rider triangle bag? Looks pretty big - they've got a picture up on the site with the bag holding a 72V15AH NMC split pack and it seems like there's room to spare for a controller and some other goodies. Could probably hold a pile of lipo.
I've got one on the way to try out, I want to see how it compares to other options. It would be nice to have a US supplier of a big triangle bag. I've got a couple 72V20AH NMC packs to throw at it
