Abstract
A bicycle frame includes an axle, a hub and freewheel assembly, two fork end members, two axle pegs, and two locking nuts. Thus, the first ramp of each of the axle pegs is rested on the second ramp of the respective fork end member to prevent each of the axle pegs from being rotatable relative to the respective fork end member, so that the first end of each of the axle pegs is clamped exactly between the respective fork end member and the respective locking nut to prevent each of the axle pegs from being rotatable freely on the axle to ensure the safety of a user who treads the axle pegs.
