Anyone familiar with the BESV JF1 E-bike?

For many years now, I've used a Trek dual sport for commuting. I'm not really much of long-distance rider, but I enjoy riding to and from work and to and from the park. I'm getting older now and have recently decided to purchase an e-bike. Thinking about what I want - a lighter bike so I can ride without the electric assist if necessary, a battery that is not too visible and one I can remove, and not too expensive - I'm thinking about the BESV JF1. It's only 16.5kg, pretty sexy looking, and only 258,000 yen.

I've not been able to find too much information about this bicycle. What I've read has been fairly positive, though. But just wondering if anyone has any experience with this bike.

p.s. I do know that the Twitch streamer Robcdee used the the JR1 Road bike version to travel all over Japan 2 years ago.
