Knowra Bicycle Bicycle A human-powered vehicle with two wheels arranged in tandem, usually driven by pedals. Its steering and balance depend on the motion of the rider and bicycle together.
Bicycle drivetrain : The components that transmit a rider’s pedaling force to a bicycle’s driven wheel. It carries force from the pedals through the chain and gears to the rear wheel.
Bicycle frame : The structural skeleton that holds a bicycle’s components and supports the rider. The frame connects the wheels, steering assembly, saddle, and drivetrain.
Dandy horse : An early nineteenth-century two-wheeled vehicle propelled by pushing the feet against the ground. It established the tandem-wheel layout that later bicycles retained.
Road bicycle : A bicycle designed mainly for paved roads, typically with narrow tires and a lightweight frame. Its design prioritizes efficient travel on smooth surfaces.
Tricycle : A vehicle with three wheels, propelled by pedals, a motor, or another power source. A third wheel can provide stability without the balancing demands of a bicycle.
Bicycle gearing : A system of gear ratios that changes the relationship between pedaling speed and wheel speed. Gear choice lets riders trade speed for easier pedaling on climbs.
Bicycle fork : The component that holds the front wheel and connects it to the steering assembly. Turning the fork changes the front wheel’s direction.
Velocipede : A name for early human-powered vehicles, including nineteenth-century pedal-driven bicycles. The pedal velocipede introduced direct mechanical propulsion to the front wheel.
Mountain bike : A bicycle designed for rough trails, commonly with wide tires and robust components. It adapts the bicycle to uneven terrain and obstacles.
Unicycle : A vehicle with one wheel, typically propelled by pedals and balanced by its rider. It shares pedal power but lacks the bicycle’s tandem pair of wheels.
