Hardly Junk, with about 40,000 Sondors Sold World Wide, we’ve heard few issues of loose magnets and planetary gears do wear out (especially when owners try and ride over obstacles at low speed and strip teeth, even stalling the motor at low speed/high torque trying to climb curbs). I can only imagine that there are over a half million or more, Bafang motors in service, especially in Asia.
You have to understand that most of our Owners come New to eBikes and don’t know that much about them, including doing research on the vehicles and components. It’s understandable that when a problem arises it’s disappointing and blame needs to be appropriately dispensed somewhere. It’s usually best to leave that until after discovery. As an Aircraft A&P and Secretary of a Airport Safety Board, we always wait until cause was determined to find fault, when investigating incidents.
My own 750Watt motor, in the Electric Black Lightning might suffer the loose magnet fate. I’m just today starting to investigate and disassemble the motor.
Two weeks ago on my way to my local airport to attend an Aviation Safety Seminar, and crossing a rather rough, uneven Rail Road Crossing, My bike quit. I recycled the power buttons and everything was fine. Finished the last few miles to the terminal and after the seminar the 20 miles home, until the next day and I had grinding in the motor case. This bike has over 13,000 miles and it seemed bulletproof but every mechanical device requires maintenance and repair, from time to time. DooDoo Occurs. No Big Surprise Really. And that’s why I have the Electric White Lightning in reserve.
Motor replacements are not all that expensive and I have a spare.
