Bicycle with combined pedal and traction lever propulsion has linear power generation between pedal/traction lever and handlebar with arm supports, using stretching and bending movements

摘要

Power transmission is via a combined pedal/traction lever (4), acting on the drive train of the rear wheel. Power is generated in a linear manner between the lever and handlebars (14) with arm supports (16), by alternately bending and stretching the body. The bottom bracket bearing shaft (3) is located in the crossbar (1) near the saddle. Crossbar and extended forks (18) form an X-shaped frame. During stretching movement, power is transmitted from the connection bolt (5) for the pedals, via cable (8) and cable pulley (9), and a chain, to a first sprocket wheel. During bending movement, power transmission is from the connection bolt via the chain (21) directly to the second sprocket wheel (19).
