Here are the weights.
v1 - with the smaller motorhttp://endless-sphere.com/forums/viewtopic.php?f=28&t=22187&start=60#p328977
0.74 kg drive only
0.9 kg for the whole system excluding battery
v2 - with larger motor, and single swing armhttp://endless-sphere.com/forums/viewtopic.php?f=28&t=22187&start=180#p342336
1.2 kg drive only
1.4 kg for the whole system excluding battery
Then add however many batteries you want
6s5000mah = 0.793 kg
5s5000mah = 0.666 kg
So with a couple of batteries 5s5000mah batteries, and the new larger motor you still only add total of 2.7kg (6lbs) to your bike.

No idea on the grade of the slopes, you can interogate the GPS data I linked to above if you are really interested.
I was running the bike on 5S.
You may have inspired another off-shoot of your designs that I have just thought of ..
.. I'll have to sketch it out tomorrow while charging LiPo before I share it, not sure if it's going to be as simple and solid.
Awesome. Can't wait to see it.

Hey my list of tools is pretty short for this design. I intentionally made it such that people could make their own with simple tools if they wanted to. But I know there will probably be bunch of people who just don't have the time or patience so I might end up making a small batch if people are interested.
Anyway if you want to do it yourself the main tools you would need are:
Angle grinder or hack saw - for cutting out swing arm, and sizing pivot/clamp blocks
Drill, various bits, and a hole saw to suit your seat tube size.
Taps - M4,M5,M6
I think that was pretty much it, apart from patience, but I manage to build mine without it.
