According to Brammo’s store locator, the Enertia can be purchased at six locations in California and Oregon. I made a map . . . click through to the page:
UPDATE: Apparently, the two bay area stores have the bike on display but not officially for sale yet, due to not getting their paperwork processed by the California DMV. As I noted in an earlier post, one of the big hold ups to selling the bikes at Best Buy is that the store must get an automobile dealer license. According to Brian Wismann, the stores will be up and running and test rides will be available sometime in the next two weeks.
Of course, if you live in the other 48 states or in the rest of the world (assuming you can come and pick it up in the U.S.), you can always order online at Brammo.com.
