HANDBIKE FOR BORROW?

this is an odd request...

in case you did not know... I LOVE TO RIDE MY BIKE!
in case you did not know... I BELIEVE THAT ALL KIDS SHOULD GET TO EXPERIENCE THE PLEASURE OF RIDING A BIKE

there is a young boy in my 4th grade son's class who moves about with the assistance of a wheel chair... his arms are strong but his legs are weak... I am not sure of what his medical condition is... but I know he is a pretty normal kid except for his body's limitations

on a few occassions I have spoken to his mother about HANDBIKES
she is interested but apprehesious of the price

Does anyone have a handbike in a smaller size that this family could borrow so that they can see if this is something that could become part of their child's life?
