They are weighing the components and making excel spreadsheets. I'm waiting till one of them realises that a pair of Y fronts weighs 100 grams less than a pair of boxer shorts. Im expect to see someone in a G string riding up an hill.

I understand the weight weeney thing on a 25 lbs x country bike, to drop a few pounds it is noticeable . But with the ebike it seems silly to weigh everything, most of the gain is in unsprung weight so put some lighter wheels and tires on and call it good
