We were 12 and my friend bought a brand-new Allstate scooter from Sears......
I started on an Allstate scooter too, my older brother got a used one that got left in the garage. Well I couldn't resist and so just started riding it. My instruction consisted of running into the house to ask my bro what the level near the right hand did. In Wisconsin, at that time, a learners permit allowed you to ride a motorcycle during daylight hours. The scooter was a bit fancier than flying junior's, it was an Itallian Vespa Clone. That thing tried to kill me on a regular basis. One day I saw something fly out of the front suspension, about the time I realzed it was a spring the entire weight of the bike came down on the front tire locking it in place. I went flying up over the handlebars and hit the road head first with the bike saving itself by using me as a sort of cushion. Lucky enough I was wearing sturdy cutoffs and a t-shirt with no helmet, so I bounced right back up, stuck the spring back in place and crawled home ignoring the blood while wondering if bailing wire could be fabricated into a suitable retainer.
That was 42 years ago and I'm still kuckleheaded enough to be riding a bike. It is possible had I been wearing a helmet during that first mishap I would have retained enough brain cells to have hung up my spurs right there and then.
