Sometimes it isn't about what she needs or expects, it about showing how much she means to you. At least it is in my case.
Man, some people just can't resist the temptation to put the ole guilt trip on you. :^)
Believe me, we wouldn't have been married for the past 31 years if the world hadn't revolved around her all that time. It's just that she has never really done any biking and that there is a better than fair chance it won't take with her, so going the cheap route initially seems like the smart thing to do ... if it does take, a very nice upgrade would be swift and demonstrative.
What about this as opposed to the other one?
