A 16″ wheel GT BMX with a back-pedal rear brake, early 90s vintage, that my neighbour brought over from Canada.
It was simple, light, indestructible (didn’t matter if the wheels buckled!) and I could bunny-hop it about two feet aged 11. Got through a rear tyre every month though…
Sold it to my friend for a fiver when I got into skateboarding 🙁
