A chart in Maya Pedal labeling the parts of a bicycle in Spanish.

Spanish Bicycle Vocabulary

On the wall at Maya Pedal is a table-sized hand-drawn poster illustrating the anatomy of a bicycle. Fortunately I know all of the English terms already, but the chart also has the Spanish translations which I still need to learn. Here is the list.

Update February 20, 2012: I created flashcards for bicycle parts on SpanishDict.com, which you can use to practice. They include pronunciations!

Wikipedia also has a good diagram of the anatomy of a bicycle in Spanish.
