@helenhall@chillen Thank you both very much. As to timing, you know sometimes luck helps the daring: I was on the other side of the zebra crossing and the pedestrian traffic light was red. I could prepare for the shot and after the light turned green I shot when I was some 2m from the young lady. In that very moment the cyclist boy crossed the crossroad ignoring the traffic light that was red for him, adding his orange wheels!
@joysabin thank you so much!. I was merely extremely lucky!
