@brian: I see you are using a tank bag. How do you attach it to the bike? Magnetic flaps aren't working since it is all plastic and aluminum. And a tank cap mount isn't perfect either.
So.. How do you do it??
I just bought some neodymium magnets from Amazon and mounted them opposite the tank bag magnets using double sided tape. Works great and I left a gap at the edges to allow me to pry the magnets off with the help of a heat gun in the event that I want to mount them in a different location for a new tank bag.
I love not having straps to mess with when I take the bag off and having the magnets exactly opposite the tank bag magnets means the bag naturally wants to align itself (although the magnets in the tank bag do move a little so I adjust them as I am putting the bag in place to make sure its perfect because I am OCD). I have put a decent amount of weight in the bag and it never seemed like it would fly off....the magnets from Amazon are pretty strong.
After I installed the DigiNow Super Charger I thought I was really going to miss the storage tank but it turns out, not at all. I find the tank bag much more useful although I am just slightly more paranoid someone will steal the whole bag if I leave it on when I go inside a store or something (I never worried about the storage tank because I assumed people wouldn't actually realize it was a storage bag and would leave it alone). However, that is easily solved by just taking it in with you if it has valuables inside. The Dowco Fast Trax is a pretty good size tank bag so it has to be moved if I am charging anyway to get to the J-port.
To install the magnets I just put the tank bag on the ground upside down and then put the tank upside down on top of it aligned where I wanted it. Then I just placed the magnets one by one without any double sided tape first. Then with all magnets in place and the tank bag aligned where I wanted it, I started to put double sided tape on the magnets one by one leaving all others in place until they were all secured.
I really like the Fast Trax tank bag from Revzilla too...it's a good size (expandable) but doesn't block the display or get in my way when riding, when it's full but not expanded it's nice to lay on, it has a shoulder strap so you can throw it over a shoulder when you go inside, it has a spot for a bladder and the interior is fluorescent (same color as the small section on top) which makes it really easy to find stuff when you open it...especially at night! Revzilla has a great break down video at the link below.
Here is a link to the magnets I used but they are no longer available. You can find others like it but I can't vouch for their quality.

And here are some pics of the tank bag installed...also...back to the original thread topic....I draw attention to the battery brick with a green vinyl wrap that is reflective when it's hit with light. Since I installed it I have noticed that instead of asking "how many cc's is that?" more people ask me "that's all electric?"...plus I just think it looks awesome the way it makes the battery look like it's glowing when head lights or a flash hit it
I didn't wrap any other part of the bike because I wanted to draw attention specifically to the battery.
Notice that it's a much darker green in this pic without the flash on.
I really like how the line between materials on the flaps aligns perfectly with the shape of the Zero tank....its like it was made for it!
Notice that in this picture the tank bag piping isn't reflecting but the battery is still turquoise...that's just by getting the right angle for the garage light to reflect back to the camera. When you walk past it in sun light it will transition from dark green to turquoise. I like it a lot
