What Emily said. I was told I have long femurs when I used to ride horses. Apparently (and it's not something I ever noticed) I look good on a horse and I would have made a great dressage rider because of my long legs and long thighs. Not so great for jumping, which is what I was into.
As for bikes, I didn't get into the angles and all because I haven't taken the time to figure it all out. But I do know it's important for the knees to be above the pedal spindle. I'm very relaxed when I ride, probably due in part to my decades of riding and watching professional racers, but also because my bike fits so well.
Here's a photo of a pro rider with excellent position on the bike. He has long femurs, too.
