This idea is absurdly underbaked…other commenters mentioned that it’s going to flip, and it is. Not to mention that no bike shop in the world will know how to work on these things.
There’s lots of reasons that this design died in the 1930’s after a short run.
But…so you know I’m a reasonable guy despite my blithering criticism…I love weird alternative vehicles and I hope that version two of this is a massive success because this world needs more tiny vehicles and fewer 8’ tall Ford F-150’s.
Best of luck!
