### Clue: Was blue bike seen here? (5)
### Answer: MOPED 
 ### Explanation: Definition: Was blue,bike seen here
  Double defn.  2nd:  Originally a sort of motorised bicycle; the word being derived from $$mo$$tor + $$ped$$al.   As with 4 Across, I thought the clue could be shorter still.  "Bike was blue." might have been a better construction?
