Awesome...a video that doesn't show how it works but does very effectively show that it's massively complicated.

Sounds like gimmicky smoke and mirrors. Increasing torque doesn't mean increasing power.
I find it hard to believe (cause you know... physics) that a series of gears (which have massive amounts of friction) is going to do anything to increase power output.

Their FAQ section claims their test riders increased their speeds 2-2.5 mph based on an initial average speed of 15 mph. If this drive system works as claimed (key phrase here), I'm surprised pros aren't clamoring for this. Even at their speeds a 0.5 mph average speed boost would be huge.

So it takes about 100w to go 15mph. Increasing to 17mph takes about 135w.

WOW... this Rube Goldberg machine produces an extra 35w (a 35% increase) !

“You definitely notice that less energy is needed at lower speeds.”

Magic drivetrain elements have been introduced every decade or so. Each and every one is a veritable miracle in that it takes a 98% mechanically efficient system (bicycle drive train) and draws significantly more power from the human body without increasing effort. Add this one to the list. tlg summed up perfectly why this doesn't work: because, you know . . . physics

Steve Jobs said "the computer is the most remarkable tool that we’ve ever come up with. It’s the equivalent of a bicycle for our minds." As Kerry pointed out, the bike is already amazingly efficient. These things - Cycfly cranks, and the scores of others like them - are the bike equivalent of fad diets. They're product developers' attempts to convince consumers there's a replacement for hard work.
