摘要： A stem connecting the handlebars and steerable fork of a cycle has one tube attached to the handlebars and another tube attached to the steerable fork with the tubes capable of being rotated and locked with respect to one another. This arrangement allows for various configurations of the handlebars and fork including the typical riding configuration as well as an alternate configuration where the handlebars are folded with respect to the fork. Change in configuration is accomplished without tools by way of a biased locking arrangement for the tubes.

摘要： A drive train system for human powered vehicles whereby the pedals move in a linear or slightly curved path, providing a superior ergonomic ride. Power is transmitted from the pedals by a flexible drive tension transmitting component to two one way locking continuous variable radius helicoids mounted on a shaft by means of a one way locking mechanism. The pedals move alternatively back and forth pulling the cables and unwinding (active phase) their corresponding helicoids and thus transferring spinning motion to the shaft. The helicoids act as a set of sprockets of continuous variable radius optimizing the ergonomic delivery of leg power to the shaft. A step-less shifting system alters the length of cable wound in the helicoids and can manually select the “zone” of the helicoids utilized for optimal power transmission. This gearing system can manually adjust the power-speed ratio according to the environment demands, akin to a gear system.
