Let me take a rare opportunity to agree with Catrike Rider. The lower
polar moment of inertia about the ground means recumbents are trickier
to balance. On the other hand, antique Ordinaries or Penny Farthings are
amazingly easy to balance even at near zero speed.
 

And had a very short life span the Penny Farthings, as the safety bike
replaced them relatively quickly, saw a talk about them by a minor TV
celebrity (Jeremy Vine) at a church fair I went to last weekend, and they
are being made and ridden again!
