Don't forget tires. Someone 6'4" is a candidate for a "29er" (700c)
if you can find one used.
Either case, you probably want the fattest tires you can get;
Schwalbe Big Apple is my default recommendation.
Peter White Cycles is a good place to consult for wheels; much good
Dyad is a good rim; I have that in the rear of my bike, 36 spokes, I
think. It's called Aeroheat if 26", there's also CliffHanger.
Sun Rhyno Lite is a cheaper, tough choice, sometimes available built
into cheap wheels.
So, for example, if you are feeling lucky, you could buy a PAIR of
built-up Sun Rhyno Lite wheels for under $100; unfortunately, they
only have 32 spokes. As risky as this sounds, that is what I use in
the summer, but in combination with some of those exceedingly fat
tires, which protect the spokes. I've carried around 100 lbs of
stuff in back, and that added to my weight (220) puts the wheel load
up into your league.
I mention this only because getting a wheelset built for you, with 48
spokes, good rims, etc, will cost 3 to 5 times that, at least looking
at Peter White's rates, and then Sun rims have proven to be strong so
far. So, if you buy them, and one fails, then you know that the
large amount of money you will later spend for custom wheels is not
One thing that an xtracycle will do for you is even out the weight
distribution; unloaded, you and the bike will put about 200lbs on
each wheel, instead of (say) 300 rear and 100 front.
