Pedals are an important part of a bicycle, as they provide the rider with the ability to propel the bike forward. The term 'pedals' can be broken down into two words: 'CYCLES' (6 letters) and 'treadles' (8 letters). CYCLES refer to the rotational motion of the pedals, while treadles refer to the pushing and pulling motion of the pedals. Together, these two words form the term 'pedals, ' which is used to describe the mechanism that allows a cyclist to move forward.
