I've built a few Early 80's ones, mostly Raleigh Burners, but have done some other stuff, And then some slightly newer stuff but generally nothing later than 2000 ish (Apart from my Sons, they both have custom mid 00's Mongoose). Fixie's seem to be the in thing for the last yr or so...not done a BMX in a while.
Here's a Custom BMX I done last year (Was a 2001 Dyno Compe), I've restored a few since this one, but prefer customising them, lets me show my artistic side lol.
And here's the last Fixie I built from just a hand painted black 80's frame... (Sold it last week)
