You know, I wouldn't know where to begin teaching an adult to ride a bike.

The idea is so inconceivable to me that someone never rode a bike when they were a little kid!

Teddy has given some great ideas... a soft surface (but grass not too long or its too hard to get wheels going)... make sure she can reach ground easily... and I am wondering why not walk beside, run behind her and hold bike while she gets the balance thing down?

Good luck and kudos to you for getting her on a bike
