Hi Leon!

It is the riders responsibility to support the horse and set things up for success.  If your gelding is not bucking you off when you are riding him then maybe the people you are allowing to ride him are not suitable or too inexperienced for the situation?  Is he really bucking them off or are they just FALLING off.  Big difference here.  You say he is your "unbroken" gelding?  Then it seems you both need to head back to the round pen and conquer the basics.  I never pair a green rider and a green horse.  It is just trouble waiting to happen.  I don't do pony rides either.  If someone wants to ride it has to be a long term commitment, not just something do do on a Saturday afternoon.  Be careful Leon with who you allow to ride your horses.  Without meaning to, they can be creating a problem that you will have to solve later.  This can be very difficult for you and your horse.  

Take a good look at what is happening with your horse and decide if the risk is worth it to both the horse and the riders.

If I have guessed wrong about some of the details here, let me know.  The more information I have, the better quality answer I can offer.

Take Care!  Smiles and Miles!  Denise
