What do you think of Yamaha Niken? Looks like it would be more similar to a normal motorcycle than a 3-wheel scooter.

A. NA in india B. Too expensive C. We get conversion kits which can add two side wheels as a rear wheel/chassis attachment which many handicapped people use here in India.
Although a self balancing bike would probably not be cheap either, at least until they become much more common.
