Abstract: The invention is a bicycle drive assembly and it generally includes a drive chain, a drive wheel including a hub, a frame including left and right chainstays, each having a raced bearing, a cassette assembly, and an axle assembly. The cassette assembly includes a body having an inner end rotatably mounted on the right chainstay bearing, an outer free end, and a cassette including a plurality of sprockets. Cooperative torque-transferring components transfer torque between cassette and body, body and axle, and axle and hub. A freewheel mechanism, as one of the cooperative torque-transferring components, allows the bicycle to coast. A drive axle is selectably movable axially between a riding position, wherein it is rotatably mounted on the chainstay bearings and supports and drives the wheel, and a release position wherein the wheel is removable.

Abstract: The present invention is an assembly of bicycle frame, fork, and handlebar stem that improves the safety and performance of bicycle riding by placing a mechanical bearing above the handlebar stem which reduces the torsional stress on the fork steering column.

Abstract: The invention is a bicycle rider fitting machine. It is used for finding optimal position of the rider on future bicycle/frame, based on parameters obtained during the workouts. Based on workout results like heart rate, power, speed, cadence, etc., what can be measured by integrated or independent electronic measuring devices, someone can compare those results and conclude the best possible positions of saddle and handlebars for particular rider. It is an apparatus that can simulate almost any position of the bicycle saddle and handlebar assembly with the reference to the Bottom Bracket centre (FIG. 1-4) as a starting 0/0 position. The saddle (FIG. 1-1) and handle bar assembly (FIG. 1-2) can be moved independently with respect to the bottom bracket. The obtained position of the saddle and handlebar position can be easily recorded for future adjustments of the machine, by means of Horizontal (X) Scales (FIG. 1-3) on the Seat Slider (FIG. 1-5) and Handlebar Slider (FIG.
