I just purchased a FLX step-through ebike. Biggest mistake ever. Usually, I thoroughly research big ticket purchases, but I was seduced by the bike’s looks and features and sale price. The Bafang mid drive motor is a noisy piece of junk! They are telling me I need to open up and grease the motor before I can ride it. Wrong!! Further, they will not fix it, exchange it, or refund my money. As I live over 2,500 miles from their business, I am effectively screwed with this defective piece of crap! My goal now is to try to inform others to beware of this company. There are much better bikes out there with companies who stand behind their bikes.
