Abstract
A crankset and bottom bracket assembly for a bicycle having a spindle. 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.
Claims20
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.
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.
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 first freewheel axle having at least one first tooth, and a first hub receiver having at least one first pawl configured for engaging said first tooth, wherein when said first ratchet mechanism is rotated in a first direction relative to the spindle, the first pawl does not engage said first 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 first pawl engages said first 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 comprising a second ratchet mechanism configured for connection to said spindle at said second end, said second ratchet mechanism comprising 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.
