Note: Since investigating musical BPM, (Beats Per Minute), and discovering that, for training purposes, a musical BPM of double the crank-pedal RPM is recommended, I will revise my BPMs as RPMs.
For most builds, 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" / inches per mile = mph
(rpm x 60min) x (Front T / Rear T) x (Wheel " x 3.14) /((12" x 5280' =) 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
