28" wheel sit-up-and-beg roadster with rod brakes and 6" wooden blocks screwed to each side of the pedals so that I could reach them. Age - 6 and 3/4. On farm field caravan site near Straford-on-Avon during the Easter holidays. Old fashioned push-until-I-could-steer without falling off teahing method (thanks, Uncle Bert). Leant to set off by pushing off from caravan steps and get off by falling off. Then learned to get off by classic leg over rear wheel manouevre, then get on ditto.
Too long ago to remember details of realising I was riding without help (Easter '47 - memory not eidetic
) but rode it every weekend that summer (hottest for umpteen decades).
weird thing is, we have to teach kids to do the scoot -swing leg over - dismount in reverse - method. None of them seem to have taught themselves. Maybe because they nearly all have bikes which are roughly the right size.
Kids, nowadays don't know they're born why, when I were a lad.... dribble, dribble, nurse!
