Trying to get my lady involved

[AM]

Right now she just sits in the truck and peers over a magazine or a stack of papers she is grading. I tried to get her to putt around the lot on my bike but she is a lil nervous. So I want to get her a 50 and get her out in the lot. She seems to be ok with that idea: any tips for her or me to keep her motivated and get over the fear?
Thanks
