I had one, it must have been second hand as I don’t remember the gears ever working, maybe it was my brothers.
It finally went whilst descending a steep hill with my mate on the back; a speed wobble developed and offed me and Marc Hoban who was sitting backwards at the time!
It was replaced by a Grifter, then various BMX and a strange Italian full sus bike. I cant remember the name of the suspension bike it was long before MTB's came along and very bouncy.
Eventually I saw the light and got a racer , albeit one with a curved top tube ala spech/bianchi 2007 and this was about 1980.
I remember the chopper as rubbish at everything except giving passengers a lift and even that was bloody dangerous.
For me the Grifter was better but I don’t remember either with properly working gears, who knows how to fix sturmey archer?
The single speed bmx where better, if your family had money you got a mongoose , if not you got one from the local garage, there was another British made one with solid plastic wheels I always fancied that, cant remember the name though anyone recall it??
