A continuously variable bicycle transmission uses movable sun rollers to adjust gear ratios via frictional engagement with conical planetary rollers.
Segmenting energy storage into a battery and supercapacitor manages transient power demands, extending operational range without external charging.
Scissor linkage frames collapse accordion-style to reduce sled volume while maintaining structural strength for game transport.
Single cylindrical housing reduces axial misalignment between speed reducer and power transmission, improving efficiency.
Nested planetary gears reduce motor speed inside a compact housing, eliminating bulky spur gear protrusions that compromise ground clearance.
Varying pitch surfaces on the camshaft exert tailored forces on switching pawls, eliminating permanent clicking and reducing downshift force requirements.
Uni-drive pulley uses a sprag clutch to enable one-directional rotation of the outer hub relative to the inner hub.
Segmented frame components cut via water jet or laser technology reduce manufacturing complexity while the folding mechanism minimizes storage volume.
A bicycle gearshift actuation device uses a closed-loop fastening track to index angular positions of the cable-winding bush.
Integrating the equalizing volume within the annular space chamber maintains system pressure to prevent gas bubble formation and cavitation.
Planetary gear mechanism enables rapid gearshifting by rotating sun and ring gears, reducing driving energy on uphill roads.
A bicycle frame design integrates accessory storage within the shock mount cavity to maintain a clean external appearance.
