On a flat road I disagree, but uphill you notice it a lot of course, but way worse is carrying the heavy bike. I take mine into trains a lot and unfortunately there are often lots of stairs and no escalators involved.
I would never take this one into a train. I'm pretty sure it is a better pack (and much better monitored) than a store bought one given what I've seen inside of those but still, the amount of energy stored in there is pretty impressive and just the thought of it going into thermal runaway is enough to ensure that will never expose other people to it.
