72v 8000w QS 273 electric bike hub motor conversion kit with TFT colorful display, Sabvoton 72v 150Amp sine wave controller,8000W Ebike kit (19inch)

This is my second ebike kit: the first came missing cables, no documentation, and mismatched connectors. This kit arrived complete, albeit with scant documentation. What really made the kit easy was their customer rep Anne—she was a available (via WeChat and other chat apps) to quickly answer questions and provide documentation. She walked me through all the steps I didn’t understand and provided help when I needed it. I’d send her a photo or screen capture and I’d get a response often immediately.

Very disappointed with this kit from NBPower. I bought this same kit from NBPower through Alibaba and it has all kind of problems. I would not recommend it.

The media could not be loaded. I've taken this bike up to 60mph with constant acceleration the whole time. Acceleration is wild be careful. Peak current draw was in mode 5 10000w. Customer is amazing. I have been communicating with customer service through whatsapp. Any problem I have encountered was solved very quickly through whatsapp. I sent pictures and video to customer service and they reply in minutes not days.

Very good and powerful motor I really like it, bike is super fast... Good communication through WatsApp very responsive ,good explanation how to assemble it. Highly recommend 👍
