To get these I had to:
And how much is that? Well, according to NCOP 14, the frame has to hold the batteries against 20 Gs of force from the front, 15 Gs from the side, and 10 Gs from rear, top and bottom. With 83 Kgs, this means I have to support about 1245 Kgs from the side. In other words, I have to imagine the bike hanging on its side and 1.2 tonnes hanging directly from the central battery frame panel.
And, you know, I'm pretty confident of that. Most of that weight is going to be directly transferred to the frame, which is already designed to take that carrying the combustion engine anyway. The panels feel strong enough to hold that load and transfer it to the bike frame easily. The edges, from the water jet, feel a bit rough but the corners are sharp and there's no tearing or wavering. Now to actually get enough time to start putting bits of it in the bike! (I need to find a tame person with a decent metal brake to do some of these bends, though...)
