geared to those wheels

Dear teachers,

Would you be kind enough to give me your considered opinion concerning the interpretation of the expression in bold in the following sentence?

That old black bicycle, it really seemed a part of her! To tease her, I said I believed that she was, and would be all her life, geared to those wheels. (A. J. Cronin, “Nurse Davies”)

geared to those wheels = attached to those wheels by a mechanism

Attached, but not necessarily by a mechanism.
