Bafang recently unveiled two motors, the M430 Cargo and M510RS, which may well give Bosch motors a run for their money. They are designed to offer strong support, especially on bikes that carry heavy luggage or cargo.https://www.notebookcheck.net/Bafang-goes-on-the-offensive-against-Bosch-with-new-mid-motors-and-up-to-800-support.1048901.0.html
I'm not happy with bafang cos I bought a brand new 750w motor and battery had it all set up on my nice pedal bike that I can't find again cos i bought the frame from Ebay and it's very rear and the police take it and give me a 1000 pounds fine and 6 points on my licence I will never ride a ebike again that's the last of that it's ever the police taking them or some one trying to rob it i hate ebikes with a passion make sure you do your checks with the laws before you spending big moneyz buying ebikes or conversion kits cos your better off getting a moped
Bafang is junk
Horrible ride quality and terrible in market support. They're barely still in business.
