Hops, spins, manuals, lip tricks(disaster,tire tap etc), barsipns, grinds. just go onto youtube and watch some pro bmxers. that should give you some ideas.
yey, militant black guy! got to love balls of steel! (y)sorry, of topic
tuck no handers are pretty simple...all the tricks u listed are still do-able at parks...start trying them over hips etc...
downside footplants are really simple and look really good so give them a shot...just make sure you dont miss the ramp as its quite painful when your hip bounces of the copin' lol...
just the usuall really: x-ups, barspins, tire taps, 180's, 3's !!!
