Do you know how much you know?

1. First, please can you rate your knowledge of how bicycles work on a scale from 1 to 7 where 1
means “I know little or nothing about how bicycles work” and 7 means “I have a thorough
knowledge of how bicycles work”. You do not need to be an expert to give yourself a “7” rating –
an expert would be rated as 7+. Also, you should rate how much you know, not how much you
think you know compared to other people.
Rating: ______
Second, as best you can, please fill in on the below schematic bicycle drawing the main bits of the
frame of the bicycle that you think are missing, the pedals and the bicycle chain. Use the symbols
given on the right of the drawing to show the frame, pedals and chain.
