bicycle frame
Two-wheeler's bones
The bicycle frame is the central structural component of a bicycle—the skeleton to which wheels, handlebars, seat, and drivetrain attach.
Frames are typically made of steel, aluminum, carbon fiber, or titanium, each offering different balances of weight, strength, and cost.
Frame geometry determines how the bike handles and fits the rider.
