Has anyone retrofitted a schlumpf on their strida?

This is great new can you give us a review on your feelings riding with the upgrade after? like speed and hill climbing? I’m seriously thinking of this but the price keeps holding me back. It’s like the price of a new dahon curve with the 3 gears, but then again that is not a strida. With the schlumpf it’s putting it into brompton territory in pricing and both bikes are handmade so the quality is there.
