170 cells, they're 45 grams each, the pack mounting hardware and box adds another two kilos or so, so say 10 Kg in all for the pack. Definitely not a lightweight :) But once it's going you hardly notice the weight other than when you have a pothole or bump. It also obviously isn't as nimble as a lighter bike but it is still very well manageable because the weight is relatively low.

What's interesting is that the duct tape is still the same, it never even cracked or tear. I don't particularly care about the looks, it just needs to work.
