How these folding fat bikes hold up depends on how heavy the rider is, how often they are ridden, how the battery is stored when not in use.
Folding fat tire ebike can be heavy, it may be difficult to transport these ebikes, sometime even difficult to fold them; a mistake in folding can damage a wire and render the ebike to malfunction.
I have bought a similar fat tire folding ebike with 500w motor for my FIL back in 2017.
He's 84 this year, about 150 lb., he's been riding it couple time a week to his favorite fishing spot in Queen, NY and going to grocery store. He doesn't transport the ebike on his car, so he doesn't really need the folding function.
Fat tires are cumbersome on pavement, but they do offer more stability with low tire pressure and less likely to get punctures. FIL doesn't pedal much, just use the throttle to get around, I'm glad he just gets outside more.
He's put maybe 800 miles on the ebike since 2017, zero issues, just put air in the tires, store the battery indoors for the winter, lube the chain and ride.
