The term 'POWERS A BICYCLE' can be solved by the crossword solution 'PEDALS', which is a 6 letter word. PEDALS are the components of a bicycle that are used to propel the bike forward. They are typically located on the bottom of the frame and are connected to the crank arms, which turn the chain and drive the rear wheel. By pushing down on the PEDALS, the rider is able to generate enough force to move the bike forward.
