Then here's my project blog, which is essentially about building the whole thing from recycled parts, some of which might actually have originally been intended for bicycle use.
http://electricle.blogspot.com
It's got almost a couple hundred posts in the last couple of years, ranging from when I was first starting and learning this stuff, to now when I have a fully working custom-built semi-recumbent electric-assisted cargo bike.
Eventually it'll have my trike build on there too, once I get enough pieces to start it. Since I try to use only recycled stuff, it's hard to find just the right bits sometimes.
Of course, since it *is* about using recycled stuff, there isn't likely to ever be anything in the way of breaking news about new EVs or EV parts on it.
Another useful build blog would be the one at http://www.packratworkshop.com/bindex.htm
with more info at the rest of the site.
