Nice, simple fabrication. It would seem, after a year, Brammo should be able to produce these. Guess I will copy you and see if I beat them!
And I like the idea of being able to take the case off to mount other platforms. I tied on a large piece of plywood one time to haul two new tires to the shop for mounting. I can also tie on a folding bicycle to ride home from the shop when in for mechanical repair, which, with the Empulse, is pretty much never!
