I've never understood the giving up bikes for a family thing. When my first child was born I put a sidecar on my Norton and we carried her in that, I also had a roadracing sidecar I used on the road at that time too, when she was 4 she was a passenger in my VW powered Ural outfit. When she was 3 weeks old I got a trials bike and competed in trials, off road riding, dirttrack, just my motorcycle life as normal. As a young family and mortgage, we couldn't afford 2 cars, so I carted the girls around to activities on my bikes, an XS1 or a C50 stepthrough, I commuted to work everyday on a motorcycle.
I seem to have given up trials, haven't done one for a year now. I commute 40km to work everyday rain or shine, freezing cold or stinking hot. Tomorrow the last of my 4 kids leaves home. They all know their father has always been riding a motorcycle their whole life. My wife never worries about me...except sometimes to ask about the trailer and tie downs, last time I had to call home was a couple of months ago.
