The present invention is a bicycle including a bicycle frame and a rear wheel suspension system that is attached to the frame. The rear wheel suspension system includes a rear wheel swingarm and a shock absorber that is engaged to the swingarm to control the motion of a rear wheel of the bicycle. A change in the vertical wheel travel (.DELTA.VWT) of the rear wheel is related to a change in the length of the shock absorber (.DELTA.SL), providing a shock rate (SR) according to the relationship: SR...

A bicycle frame has a front frame, a lower bracket assembly, an upper bracket assembly, a rear frame and a shock absorber. The front frame has a head tube, a down tube, a bottom bracket shell and seat tube. The lower bracket assembly is connected pivotally to the bottom bracket shell and has a lower connecting bracket. The upper bracket assembly is connected pivotally to the seat tube and has two upper connecting brackets. The rear frame is connected pivotally to the upper connecting brackets an...

A shock absorbing device is mounted between a stem and a front wheel axle of a bicycle to reduce shock that is transmitted to a handlebar, and includes a support leg disposed to swivel with the stem, a lever with a proximate end anchored relative to the axle and a distal end fitted to the support leg, a crank member with a journalled end journalled on the axle and a web portion coupling with one of the proximate end and the intermediate portion of the support leg and terminating at a coupling en...

This application relates to rear suspension system for bicycles, such as freeride, downhill and trail-style mountain bikes. The suspension system includes a rear suspension for coupling the rear wheel of the bicycle to the bicycle frame, a rear shock absorber disposed entirely in front of the seat tube of the frame and a linkage for operatively coupling the rear suspension to the rear shock absorber. The linkage intersects the longitudinal axis of the seat tube for transmitting rear suspension f...

A bicycle frame set comprising a main frame and a rear wheel suspension system. The rear wheel suspension system comprises a first link member with an upper end pivotally connected to a seat tube of the main frame at a link pivot point located rearward of an axis extending between a bottom bracket of the main frame and an intersection of the seat tube and a top tube of the main frame. The first link member has a displaceable lower end pivotable about the link pivot point. The swing-arm is pivota...

A bicycle including a frame having a main frame portion and an articulating frame portion pivotally mounted to the main frame portion and carrying a rear wheel of the bicycle. A shock absorber preferably is operably connected between the main frame portion and the articulating frame portion. Preferably, the top tube and down tube of the main frame contact one another for a distance extending rearwardly from the head tube of the main frame. In one arrangement, the down tube has a non-circular cro...

A bicycle suspension assembly elastically supports a first frame member to a second frame member. The suspension assembly preferably forms a bottom bracket unit that allows the rear frame member to pivot about the axis of the bicycle crank axle without any adverse affects to the drive train assembly. Preferably, the suspension assembly includes a first suspension member, a second suspension member, a first bearing unit, and a shock-absorbing structure. The first bearing unit is operatively dispo...

A bicycle is equipped with a rear wheel suspension having a swing arm with one or more generally cantilevered side arms, which are capable of withstanding bending and torsional loads and isolating said loads from the rider. A bottom portion of the bicycle frame includes a pedal sleeve. A pedal or crank assembly rotates within the pedal sleeve about a rotational axis with a fixed location relative to the frame. The swing arm is pivotally secured to the frame for movement about the rotational axis...

A wheel suspension system having under powered acceleration a squat response that begins in the realm of anti squat and passes through a point of lessened anti squat at a further point in the travel.

The invention relates to a bicycle adjusting device, in particular an adjusting device for adjusting the height of the front wheel suspension, the rear wheel suspension, the saddle or of the steering mechanism of a bicycle, e.g. of a mountain bike, a bicycle with at least one bicycle adjustment device, as well as a bicycle-steering head bearing system, whereby the adjustment has at least one double-acting piston-cylinder assembly with a first cylinder space (14a, 34a) and a second cylinder space...
