Interesting. Though I might not call them "top inventions". In bicycling history, I would offer 2 for ultimate top: the rubber pneumatic tire developed for bicycles, by Scot-born John Dunlop. And the diamond bicycle frame, often attributed to John Starley of England, that allowed 2 wheels of the same size, with chain pedal drive, making the awkward & unstable "high wheeler" bicycle obsolete. Honorable mentions would go to multiple derailleur gears, internal hub gears, and the various brake systems bikes use.
Though not often recognized as such, I would call the bicycle one of the most import inventions of modern times. It transports a large portion of the human race throughout the world. A bicycle allows our own muscles to move us at a faster speed, and with less effort over greater distances, than we ever can do on our feet.
