Motor bad, now axle snapped on other end. Told you ancheer is garbage. Ditch it before the frame snaps and the steering column stabs you in the belly. That's what a Sears bike did to me in 1957. Dad found a real bargain.
I've had 5 ebike motors and none of them the axle snapped. I did snap a 6 speed shimano rear axle on a Diamondback MTB. I weighed an enormous 170 lb and don't jump curbs or picnic tables. Consumer garbage. Don't buy that brand either. Get a used trek, giant, specialized, cannondale, or kona non-electric bike on a resale website and electrify it yourself with a power wheel kit. Or even an 80's schwinn; mine was great before I wore out the sprockets at about 15000 miles. To get quality I had to buy a new $2000 bike since my legs are so short and all the used bikes my size are kiddie quality. The Pacific Quantum I picked up for $75, the shimano 7 speed rear axle came unscrewed & dropped the balls on the road. Also, the crank got loose on the shaft at ~2000 miles and wouldn't come off to be replaced. Consumer garbage, don't buy that brand either. Shimano makes reliable 8,9,10,11 speed derailleur axles, that cost 3-5 times what their consumer grade 6 & 7 speed garbage costs.
