Reasoning that I have used (with a BF, who had no say over my money, but I am a wimp, and he was a control freak ):

Now that I am riding regularly, I don't want to get out of the habit if my bike breaks down.

This bike is for X, the other is for Y.

But I will but if hubby had some of his money to spend on hobbies, he wouldn't feel the need to discuss it and agree on it. We women are so trained to try seek an agreement!

Wish you luck!
