FIELD: transport engineering; bicycles.
SUBSTANCE: to prevent frequent changes of gears, part of transmission gear ratios is omitted as follows: set of gears is provided, each set containing less gears than preceding one. When rider selects required set, controller provides change of gears within selected set of gears. Rider can select other sets of gears by stepping up or stepping down. Controller provides cruising at which possibility of undesirable gear change is reduced. For sharp deceleration and subsequent renewal of motion, "missing" conditions are provided for additional reduction of number of accessible gears.
EFFECT: reduced number of gear changes, possibility of adaptation of transmission to specific riding conditions.
