I guess my 1st "proper" MTB was a Raleigh Lizard that I bought back in 1990 and took out on proper rides in the wilds (as well as trips to the chinese takeaway)
Before that I was busy jumping around on and breaking various inappropriate bikes on the fields next to my parents house, but not really MTB, more a poor kids effort at BMX when he didn't have a proper BMX to ride on.
