If buying from ebikes.ca, be sure to write them with your planned purchase and ask them to verify that it makes sense and if they're seeing any issues with it.

Some parts/combinations have known issues that you're just better off avoiding.

I can’t believe I’ve seen a link to ES in the wild! I used to love this website. Back in 2010 it was like a second home to me. That was before electric vehicles had undergone the revolution that was brought by Elon musk. If you wanted an electric vehicle that was good you had to literally build it yourself. I think the white zombie will always be the pinnacle of that era. And the countless ebikes that people made.

I haven’t been keeping up with the forums lately. The last I checked, the bottle neck for performance was people’s motors overheating. So there was a general effort to take a stock motor from China and drill coolant channels into it and attach a cooling loop. Dr base had some promising progress but I’m not sure anyone ever finished it.

There used to be this guy who you could send your inverter to in SF who would add extra solder to the power traces and modify it from stock to juiced up and ready for tons of current. The atmosphere in that website was just perfect because it was just a bunch of dudes who were a weird combination of speed freaks and electronics nerds. Amazing times.
