The crankset and bottom bracket assembly comprising a first crank. The first crank comprising a first ratchet mechanism configured for connection to the spindle at a first end. Wherein when the first ratchet mechanism is rotated in a first direction relative to the spindle, the pawl does not engage the tooth and the first crank freewheels relative to the spindle, and wherein when the first ratchet mechanism is rotated in a second direction relative to the spindle, the pawl engages the tooth and rotation of the first crank drives the rotation of the spindle. ## Claims ### Claim 1 A crankset for a bicycle having a bottom bracket assembly comprising a spindle having a spindle first end and a spindle second end, said crankset comprising: a first crank assembly comprising a first crank, said first crank comprising a first ratchet mechanism configured for connection to said spindle first end, wherein when said first ratchet mechanism is rotated in a first direction relative to the spindle, said first crank freewheels relative to said spindle, and wherein when said first ratchet mechanism is rotated in a second direction relative to the spindle, rotation of said first crank drives the rotation of said spindle. ### Claim 2 (depends on 1) The crankset of claim 1, wherein said first ratchet mechanism comprises a freewheel axle having at least one tooth. ### Claim 3 (depends on 2) The crankset of claim 2, wherein said first ratchet mechanism comprises a hub receiver having at least one pawl configured for engaging said tooth. ### Claim 4 (depends on 1) The crankset of claim 1, wherein said first ratchet mechanism comprises a freewheel axle having at least one tooth, and wherein said first ratchet mechanism comprises a hub receiver having at least one pawl configured for engaging said tooth. ### Claim 5 (depends on 4) The crankset of claim 4, wherein when said first ratchet mechanism is rotated in a first direction relative to the spindle, the pawl does not engage said tooth. ### Claim 6 (depends on 5) The crankset of claim 5, wherein when said first ratchet mechanism is rotated in a second direction relative to the spindle, the pawl engages said tooth. ### Claim 7 (depends on 1) The crankset of claim 1, further comprising a second crank assembly comprising a second crank, said second crank comprising a second ratchet mechanism configured for connection to said spindle second end, wherein when said second ratchet mechanism is rotated in a third direction relative to the spindle, said second crank freewheels relative to said spindle, and wherein when said second ratchet mechanism is rotated in a fourth direction relative to the spindle, rotation of said second crank drives the rotation of said spindle. ### Claim 8 (depends on 7) The crankset of claim 7, wherein said second ratchet mechanism comprises a second freewheel axle having at least one second tooth, and a second hub receiver having at least one second pawl configured for engaging said second tooth. ### Claim 9 (depends on 8) The crankset of claim 8, wherein when said second ratchet mechanism is rotated in a third direction relative to the spindle, the pawl does not engage said second tooth and said second crank freewheels relative to said spindle. ### Claim 10 (depends on 8) The crankset of claim 8, wherein when said second ratchet mechanism is rotated in a fourth direction relative to the spindle, the second pawl engages said second tooth and rotation of said second crank drives the rotation of said spindle. ### Claim 11 (depends on 8) The crankset of claim 8, wherein when said second ratchet mechanism is rotated in a third direction relative to the spindle, the pawl does not engage said second tooth and said second crank freewheels relative to said spindle; and wherein when said second ratchet mechanism is rotated in a fourth direction relative to the spindle, the second pawl engages said second tooth and rotation of said second crank drives the rotation of said spindle. ### Claim 12 (depends on 1) The crankset of claim 1, further comprising a second crank assembly comprising a second crank, said second crank comprising a second ratchet mechanism configured for connection to said spindle second end; wherein said first ratchet mechanism comprises a freewheel axle having at least one tooth, and a hub receiver having at least one pawl configured for engaging said tooth; wherein when said first ratchet mechanism is rotated in a first direction relative to the spindle, the pawl does not engage said tooth; wherein when said first ratchet mechanism is rotated in a second direction relative to the spindle, the pawl engages said tooth; and wherein said second ratchet mechanism comprises a second freewheel axle having at least one second tooth, and a second hub receiver having at least one second pawl configured for engaging said second tooth; wherein when said second ratchet mechanism is rotated in a third direction relative to the spindle, the pawl does not engage said second tooth and said second crank freewheels relative to said spindle; and wherein when said second ratchet mechanism is rotated in a fourth direction relative to the spindle, the second pawl engages said second tooth and rotation of said second crank drives the rotation of said spindle. ### Claim 13 (depends on 1) The crankset of claim 1, further comprising at least one chain ring. ### Claim 14 (depends on 1) The crankset of claim 1, wherein said first crank assembly further comprises a pedal. ### Claim 15 A crankset and bottom bracket assembly, said assembly comprising: a bottom bracket assembly configured for insertion into a bracket shell of a bicycle frame, said bottom bracket assembly comprising a spindle having a first end and a second end; a first crank assembly comprising a first crank, said first crank comprising a first ratchet mechanism configured for connection to said spindle at said first end, said first ratchet mechanism comprising a freewheel axle having at least one tooth, and a hub receiver having at least one pawl configured for engaging said tooth, wherein when said first ratchet mechanism is rotated in a first direction relative to the spindle, the pawl does not engage said tooth and said first crank freewheels relative to said spindle, and wherein when said first ratchet mechanism is rotated in a second direction relative to the spindle, the pawl engages said tooth and rotation of said first crank drives the rotation of said spindle; and a second crank assembly comprising a second crank, said second crank configured for connection to said spindle at said second end, wherein when said first crank freewheels, said second crank drives said spindle. ### Claim 16 (depends on 15) The crankset and bottom bracket assembly for claim 15, wherein said second crank comprises a second ratchet mechanism configured for connection to said spindle at said second end, said second ratchet mechanism comprising a freewheel axle having at least one tooth, and a hub receiver having at least one pawl configured for engaging said tooth; wherein when said second ratchet mechanism is rotated in a third direction relative to the spindle, the pawl of said second ratchet mechanism does not engage the tooth of said second ratchet mechanism, and said second crank freewheels relative to said spindle; and wherein when said second ratchet mechanism is rotated in a fourth direction relative to the spindle, the pawl engages the tooth of said second ratchet mechanism and rotation of said second crank drives the rotation of said spindle. ### Claim 17 (depends on 16) The crankset and bottom bracket assembly for claim 16, wherein said first direction and said third direction are the same direction relative to said spindle, and wherein said second direction and said fourth direction are the same direction relative to said spindle. ### Claim 18 A crankset and bottom bracket assembly, said assembly comprising: a bottom bracket assembly configured for insertion into a bracket shell of a bicycle frame, said bottom bracket assembly comprising a spindle having a first end and a second end;
