Hey, Brasco here. Searched a couple times with little luck, but wanted something a little more concrete: where do you guys prefer to purchase your motors? I'm shooting for 5000w hub drive, but I don't know which sites/companies are most reputable. I've looked up the stuff under the "basics" thread, searched a few random things and only come up with Alibaba, EBay, Amazon (sort of) and then Bafang/Luna. . . But 5kW seems like an overseas thing mostly. Any help/info is appreciated.
You are worrying about the wrong thing.
If even if you buy from a vendor here in the States, it all comes from the same place, Asia, mostly China.
You can get better response from a US based vendor in terms of help and perhaps speed of delivery, but you will pay for the privilege.
Actually, the motors themselves are the most reliable component in the system, what you need to concern yourself with is matching the pieces for the best performance. The best way to do that is to search (using search-words) the forum for builds simular to what you want to do. The answers to your "where to buy" questions will be answered in the course of your searches.
Good luck.
