OK, I'm going to go out on a limb here and defend BMX...this isn't senseless arguements, but rather a discussion...
stylinruss - What stuff are Jeff Lenosky and Dylan Tremblay doing that BMX's aren't/can't? Guys have fakied (ridden backwards) down stairs, hell they've been going fakie, then 180'd down stairs to land forwards, or gone fakie-360 down stairs-land fakie. There's a lot of guys running front brakes, too. Guys are doing wallrides to hang 5's, which is where you have one foot on your front peg, one foot hanging off, nosewheelieing away...
I ride BMX, MTB and moto's, and the transition between BMX-MTB is a lot easier than it is from MTB to MX. I can do just about all of my non-peg BMX tricks on my MTB (apart from small, technical stuff), but to hell if I could do that stuff on my MX bike.
You might get pissed at BMX's thinking MTB is lagging behind, but when MTB guys think BMX is a bunch of acne covered teenagers on $300 Haro's doing x-ups, it opens a whole can of worms...
Fuzzy - I admit they are a bit harder to do, but check out one of Mat Hoffman's videos fromback in 87/88. He jumped on a MTB, jumped his box jump, and on the FIFTH jump, done a perfect flip on it. And this was on a bike that would now be laughed at if you rode it anywhere...
Socket - Believe me, there is still A LOT of crap BMX stuff on the market. And cheap? My bank card doesn't think so, haha. A lot of gimmick's out there, too. Norco, with their disc brake race bike. Pointless. Euro bottoms brackets in freestyle bmx, they're just too weak and save zero weight.
Ty - I agree, but is it really progression? All in all it's still the same trick, going the same height, with the same difficulty, but it's just inaccesible by a BMX.
