Has anyone retrofitted a schlumpf on their strida?

Hi,

I been reading this thread since yesterday, I recently bought a strida LT (single speed) to use for daily commute from home to office here in France, I thought I wouldn’t be needing the gear option that’s why I bought the LT, but i was wrong…

Is Schlumpf speed drive compatible for my LT? I’m not well verse about the gearing description. On hydra & Blackstridaaustria post, it looks like it is not advisable to do my planned upgrade.

BR,
Chris
