If you can still return the bike to Amazon, do that instead. Take some extra time and do some research and ride some actual e-bikes at a shop or shops., you will get a better product and better support which is crucial in the end the amount of dead fat tire e-mopeds at my old shop was staggering so many that needed quite a bit of work that the customers didn't want to deal with or stuff that needed warranty that the company had no interest in supporting,

If you are dead-set on keeping this thing then get the Billionaires at Amazon or the OEM or Zoom to send you a new fork as this one is broken and also ask you local shop what labor would be to replace the fork and have them cover that as well. A new bike should not break out of the box but it is a good sign of more to come.

Zoom is not a company I want for a fork. Fox, Rockshox, MRP, Öhlins, SR Suntour (on their air forks to a degree) and DVO are companies I would happily run forks from but if you find stuff like Zoom and similar stuff it is a good sign to be careful as those parts are designed to be very very very low initial cost and of as little quality as they can really get away with.

If you want you can pay for a piece but I wouldn't spend your hard earned money on something that was broken near out of the box.
