It has a tubular design underneath the plastic that refers a bit to the f55 as well (pic below).
It's available with a central footrest (option) and the R-net 120A controller.
front wheel size is good enough for outdoor use...
It looks like it's fairly easy to move the c of g rearwards and can come with light seating in stead of bulky rehab seating...
swapping to black narrow tubeless tires (3,5") should be easy... BM style turf tires would require major surgery to the rear swingarm setup.
They have optional 13km/h (8.5mph?) motors which could be usefull if you live in a flat area and/or are lightweight.
I'd add it to my shortlist if I was buying new now because it has everything the c350 and alex or Puma40 have and adjustability.
Just not an easy option to (easily) switch to wide tires.
Too bad it's ugly.
I'd powdercoat the frame and ditch the plastic shroud.
