Sorry guys, I thought I posted a while back that Jaymic ultimately said "no" to producing these. They figured the cost would deter anyone from buying one, when compared to the TEP $170 version. I have a friend who makes custom mt bike racing frames who was going to do a few, but he's still as of yet too busy to take it on. Since then I've fabricated my own battery brackets out of angled steel that screw into the trunk floor, which incorporate an off the shelf battery holder from the top. It works great so maybe it was best not to spend $300 on something I really didn't need after all... but an aluminum rear brace batt holder would LOOK trick! mb 73tii
