If it's direct drive and a 36" wheel then it's <33 gear inches i.e. about 34/28 on a 700c bike with similar size tyres.
Your saddle height is going to be about 50cm and unadjustable, so an inside leg of ~45cm. So this would be about the right size for someone who is 3 ft 4".
Effective top tube would be like 800mm (WTF? have I got this wrong?)
