FIELD: transport.
SUBSTANCE: pedal levers (6) are jointed by cord (17, 30) with drive spiral-like segments (11) of gear ratio control mechanism (8) and drive wheel free running mechanism (37, 38). Control elements vary gear ratio by turning spiral-like variable-radius segments (11) with the help of cord (19), drive sectors (10) and cord (17). Control elements vary the height of rise of levers (6) via cord (44), levers rise mechanism (23-27) and cords running around drive sectors (10). Mechanism (31) allows tensioning the cords that can be made from kevlar.
EFFECT: higher efficiency.
