Which came first, the aeroplane or the bicycle?

the bicycle came first, by 86 years. Karl Drais rode his running machine near Mannheim.

Side by side

the aeroplane

The first flight lasted 12 seconds and covered 36 metres — less than the wingspan of a Boeing 747. The Wrights' real contribution was not the engine but three-axis control, which they worked out with a wind tunnel of their own design after finding the published lift tables wrong. Sixty-six years separate that flight from the Moon landing, well within a single lifetime.

the bicycle

The first two-wheeler you could balance and steer was Drais's laufmaschine of 1817, which had no pedals — you pushed with your feet. Pedals arrived in the 1860s, the chain-driven safety bicycle with equal wheels in 1885, and the pneumatic tyre in 1888. The bicycle is younger than the steam locomotive, younger than photography's first experiments, and roughly contemporary with the stethoscope.
