Preamble Fork Options

I put together an e-bike for commuting based on a preamble frame. I absolutely love it, it came together great. I’m still getting some items fine tuned as I go along. I’ve got 300 miles on it over the last month and it’s been a blast.

I cut the fork too short by about 40mm, so I bought a Sunrise bar to compensate. So far so good, however I’d like to buy a new fork and not cut it too short to try out a couple different handlebars.

All of that being said, I can’t find a 700c Preamble fork for the life of me, anywhere. Does anyone have any recommendations for a replacement fork?
