I just bought a Giant Lafree 2 great back. It has the battery in the back on a bike rack. I already own the Topeak MTV bag is there an adapter that I could add to the bike rack to use this bag withou effecting the battery? Thanks for the help
I think I remember from my research when looking for a bag for my La Free that there was not an adaptor available (I could be mistaken, it was months ago).
Got this bag instead from Amazon, and am quite happy with it:

It attaches with 4 velcro straps so it should easily mount to the exposed top bars on your Giant's rack. Here it is on my Haibike. It is on a rack exactly like on the bike next to it (my wife's Haibike). I like it a lot - in fact I just bought a second one.
