What size bike?

I am a daily rider just to take weight off. I ride on Asphalt, no off
road. I am 6'4 235 and want an inexpensive speed bike. Is there any in
my size is right for me..I have long legs.? What brand? I also do not
like bending over, I like sitting up in a straighter position.

Well, you should probably be looking for a bike with a frame larger
than 60 cm, probably more like 62 to 63 cm. You might be interested
in a "hybrid" or "comfort bike" which will have handlebars that don't
drop down but rise instead.

For what it's worth, I am also 6'4" and normally am most comfortable
on a 63 cm frame. The larger size keeps the handlebars from being
too low. I prefer drop bars and am more comfortable having a more
"bent over" position on the bike for the rides I do (usually 50 miles
or more).
