It was probably fixed wheel. I certainly hope it was anyway!. Alternatively it may have had a coaster (back-pedal) brake in the rear hub- no cables or levers for that.
With fixed there's no freewheel so you brake by resisting the motion of the pedals. Most people run them with a front brake though.
