Travels by pedal power (6)
I believe the answer is:
cycles
'travels by pedal power' is the definition.
(I've seen this before)
This is the entire clue.
(Other definitions for cycles that I've seen before include "Rides" , "Complete sets or series of songs or poems" , "Rotations on bikes" , "Sequence of songs" , "Travels by pedal power" .)
