I will need lots of practise to get it down to the sub-15s what I routinely do on the Yeah. For one thing, I have to figure out what to do with the crank arms, what the most optimum position is. I have tried to follow the (excellent Australian) manual's directions, but that didn't seem to help. I will just have to work out the best one for myself like I did on the Yeah. Part of the problem is the cranks move when folding so they don't end up where you think.
I've always liked this video and try to emulate his procedure ... he cuts it under 10 sec..
