Abstract: An adult tricycle has a front frame and a rear frame that are pivotally connected together and a suspension for minimizing shock as the tricycle is driven over a surface. The suspension includes a shock absorbing element having a leading end that is pivotally connected with the front frame and a trailing end that is pivotally connected with the rear frame. The tricycle has a front wheel with a diameter that is bigger than the diameters of the rear wheels and a seat that sits higher than the diameter of the front wheel. The adult sized tricycle enables parents to ride cycles with small children and provides a safe, stable cycle for mature adults and senior citizens.

Abstract: A crank arm system for a cycle is provided including a first crank arm, a second crank arm, a first crank arm end, and a second crank arm end. The first crank arm has a length extending along a first plane. The second crank arm has a length extending along a second plane. The first crank arm end has a pedal coupling portion and a crank arm coupling portion having a length configured to extend along either the first or second plane when coupled to the respective first or second crank arm. The second crank arm end has a pedal coupling portion and a crank arm coupling portion having a length configured to extend along either the first or second plane when coupled to the respective first or second crank arm.

Abstract: A pivoting bicycle link is provided for interconnecting a bicycle and a wheeled device pulled behind the bicycle. The pivoting bicycle link includes a first portion, a second portion, a pivot and a collar. The first portion is configured to operably couple the link to a portion of the bicycle. The second portion is configured to operably couple the link to the wheeled device. The pivot is located to permit the link to move about two axes. The collar is configured to operably couple the pivot to at least one of the first and second portions. The collar has a length configured to limit compression of the pivot.

Abstract: A tow bar system for coupling a bicycle to a wheeled trolley is provided. The tow bar system includes a first portion, a second portion, a trailer arm and a wheel. The first portion is configured to be removably coupled to the bicycle. The second portion is configured to be removably coupled to the wheeled trolley. The trailer arm extends between the first and second portions and at least a portion of the trailer arm having a substantially arc shape to avoid contact with the bicycle.

Abstract: This invention relates to a means for attaching a twist shifter to a “Maes Bend” shaped handle bar typically found on road type bicycles. Twist shifters provide the rider better control of bicycle while riding and a more positive shift mechanism. By mounting the shifter in the center section of the handle bars the rider does not need to remove or reposition their hands for shifting and a positive click indicates that a successful shift has been accomplished.

Abstract: The invention provides a bicycle having an improved shock absorbing suspension system and an improved shock absorber for a bicycle. The suspension system comprises a single pair of improved shock absorbers associated with the rear wheel of the bicycle. The improved shock absorber comprises an elongated housing having a hollow cylindrical core which receives a shock absorber rod having a piston head. The core of said housing is provided with a multiplicity of longitudinally disposed shock absorbing springs arranged end to end between the closed end of the housing and the piston head. The springs possess different innate resistances to compression so that the shock absorber has a varying shock absorbing capacity. A return spring is lodged in the housing core on the opposite side of the piston head between the piston head and the end of the housing which receives the shock absorber rod.
