It is acknowledged I'm a novice at dealing with China firms, but asking this question anyway. When trying to communicate with NBPower as well as Risum Motors, it's virtually impossible to obtain straight answers. Here's the question.....are there ebike brokerage firms in the US who broker products from NBPower, Risum and other China ebike conversion kit firms? I'd so much rather deal with an American firm verses China. However, these two firms have what I wish......primarily a powerful kit who laces fat wheel in 24" size. Any insights greatly appreciated.
