I'm trying to get my wife to ride more. She has a Scott Sportster that she rides on the local greenways. She still won't take responsibility for stuff like checking/adjusting tire pressures and chain lubing but she does seem interested in riding more. We did almost 30 miles on Sunday which is a lot for her.
I have found a way to exploit riding with her to buy myself a new toy too!!! Since I'm a much stronger rider than she is I just ordered a new single speed so I can still get a good workout without leaving her in my dust.
