For most builds, or purchases, people should take into consideration the pedal assist capability of the bike.

(RPM - crank-pedal Revolutions Per Minute - pedal rate)
60 rpm is considered a casual-sustainable rate
90 rpm is, a more, top sustainable rate

Figured - rpm x ratio x wheel size = mph

(rpm x 60min) x (Front T / Rear T) x (Wheel " x 3.14) / 63360 = mph

26" wheels - My EZip Trailz (OEM)
(60rpm x 60min) x (44T/14T) x (26" x 3.14) / (12" x 5280') = 14.57mph
(90rpm x 60min) x (44T/14T) x (26" x 3.14) / (12" x 5280') = 21.86mph

26" wheels - My EZip Trailz (w/32-11T upgrade)
(60rpm x 60min) x (44T/11T) x (26" x 3.14) / (12" x 5280') = 18.55mph
(90rpm x 60min) x (44T/11T) x (26" x 3.14) / (12" x 5280') = 27.83mph

26" wheels - My Black Widow (Upgraded 34-11T)
(60rpm x 60min) x (48T/11T) x (26" x 3.14) / (12" x 5280') = 20.24mph
(90rpm x 60min) x (48T/11T) x (26" x 3.14) / (12" x 5280') = 30.35mph

27" Wheels - My old 12 speed
(60rpm x 60min) x (52T/12T) x (27" x 3.14) / (12" x 5280') = 20.87mph
(90rpm x 60min) x (52T/12T) x (27" x 3.14) / (12" x 5280') = 31.31mph

700c = 28" wheels - My Haro Express Deluxe
(60rpm x 60min) x (48T/11T) x (28" x 3.14) / (12" x 5280') = 21.80mph
(90rpm x 60min) x (48T/11T) x (28" x 3.14) / (12" x 5280') = 32.69mph

29'er Wheels
(60rpm x 60min) x (48T/11T) x (29" x 3.14) / (12" x 5280') = 22.58mph
(90rpm x 60min) x (48T/11T) x (29" x 3.14) / (12" x 5280') = 33.86mph

Why wouldn't you use "RPM", the industry standard for things that go 'round, and save BPM for heart rate, also an industry standard?

Many bikers tend to train, and adapt their pedal cadence, to the beat of various musical numbers, "getting their timing and rhythm right." It should be noted, the BPM music timing is, per footfall. So, 2 Beats per revolution.

PC for Pedal Cadence was way too confusing.
BPM - Beats Per Minute - from the music industry, as in timing and music, seemed most appropriate.(In fact, cadence is also a musical term)

And ... "Beats Per Minute - pedal timing", seems perfectly clear ... ?

How can "pedal cadence" be too confusing, when cadence is the basis for all things cycling? This is a bicycle forum. Despite the rubbish you have just posted about musical numbers, any cyclist that that is doing any sort of real training is concerned with maintaining a certain cadence (which is the RPM of their cranks) and keeping their heart rate (BPM) within a specific range.

Besides, a gentlemen whose untimely passing followed my father's by two weeks has already provided the cycling world with this handy calculator.

I figured it was a DJ thing. iTunes database allows music to be sorted by BPM. Should a rider select music for his iPod that matches his desired heart rate or pedal cadence?

I don't believe anyone would recognize PC, or C, in a mathematical formula.

The program is designed for training your pedal cadence.
Music has long been used as a physical training aid, for developing ... rhythm.
Hence the musical cadence from Army drill Sergeants.
Teaching the lowly grunts, how to shuffle their feet.
(Sorry ... Armed forces drill training! Didn't intend to slight any branch.)

Of course, you should monitor your heart rate, at least during training,
Much of the purpose of training, is to find your optimal cadence, then to gradually improve upon it. (duration, speed, effort - singularly, or combinations, thereof)

To improve your muscular efficiency!
And yes, your heart is one of those muscles.

"Stripes" also has some nice examples!

I like to listen to The Pretenders "Back on the Chain Gang" when I ride.

My guess is that The Pretenders would make a ride much more enjoyable than something like Pantera. Does that happen to coincide with a higher cadence, or a lower one? Because if you follow Gunnie's approach, you'll be at the back of the pack, grinding along at 60 RPM.
