When I was 5 and my brother 8 my dad decided the family should travel more. He had a motorbike and was a bit of a bodger, so he made a sidecar for the bike out of the old pram - one of the deep bodied black prams popular in the 50's. He converted the wheels somehow and attached the whole contraption to the bike.
He'd nailed a plank across the back, which my brother sat on, gripping on to the sides like grim death, and I had to sit in the front cramped up, no helmets or protective clothing. Every journey was agony for me.
We went on several painful rides across London.
Thankfully dad got bored of his project after a couple of long journeys and life returned to the normal no days out with the freedom of playing in the street or local park.
