G-line handlebar options?

Love taking my G Line out for evening rides in the Dutch dunes, but I find the stock handlebar angle becomes a bit uncomfortable on my wrists over longer rides.

I’d like to do some multi-day touring and am wondering whether anyone has found alternative handlebars that provide a more neutral, flatter hand position. I’d still like to keep the bike foldable for train travel, although I’m not concerned if the bars stick out a little when folded.

Any recommendations or experiences would be much appreciated. Thanks!
