Abstract
A pedal assembly includes an axle extending through the passage in the pedal and a nut is inserted into the passage from a first end of the pedal and threadedly connected to a threaded section of the axle. A bearing is mounted to the nut. Another bearing is inserted into the passage from a second end of the pedal and is mounted to the axle. A contact plate extends radially outward from an outer periphery of the axle and includes a friction surface. A crank has a threaded hole with which another threaded section of the axle is engaged. The friction surface includes multiple spikes so as to firmly contact the crank.
