Apparatus System and Method for Providing Adjustable Cranks in an Exercise Device

摘要

A crank-driven exercise device (100). The crank-driven exercise device (100) includes a frame (102), a spindle (202) rotatably connected to the frame (102), a crank arm (104) connected to the spindle (202), and a user input (208) connected to the crank arm (104) configured to receive a force from a user. In some embodiments, the crank arm (104) includes a proximal section (204) and a distal section (206). The proximal section (204) may be connected to the spindle (202) at a spindle interface (302), the distal section (206) may be rotatably connected to the user input (208) at a user input interface (306), and the distal section (206) may be selectively fastenable and selectively rotatable relative to the proximal section (204) at a crank interface (304).
