Spoke: connects wheel rim to hub. Usually wire with one end swaged to form a head and one threaded end. A typical wheel has 36 spokes; Speakers: loudspeakers specifically made for bicycles and/or strollers for cyclists and pedestrians with children to listen music or answer phone calls on their mobile devices when
The centerlock wheel and hub system was first introduced by Rudge-Whitworth in the early 1900s, for use in automobile wire wheels. Initially called "QD" (for "quickly disconnectable") the basic mechanism for "knock-off" style centerlock hubs was patented by 1908. It was quickly adopted by auto manufacturers and racers.
A wheel hub motor, hub motor, or in-wheel motor is a motor that is incorporated into the hub of the wheel. Wheel-hub motors are commonly found on electric bicycles. Electric hub motors were well-received in early electric cars, but have not been commercially successful in modern production cars [1][2] because they negatively affect vehicle ...
Operation. The hub assembly is located between the brake drums or discs and the drive axle. A wheel is bolted on it. Depending on the construction, the end of the hub comes equipped with the splined teeth. They mate the teeth on the axle shaft. The axle hub spins along with the wheels bolted to it and provide power to the wheels in order to rotate.
Steering knuckle. In automotive suspension, a steering knuckle or upright is that part which contains the wheel hub or spindle, and attaches to the suspension and steering components. [1] The terms spindle and hub are sometimes used interchangeably with steering knuckle, but refer to different parts. The wheel and tire assembly attach to the ...
The hub is the center of the wheel, and typically houses a bearing, and is where the spokes meet. A hubless wheel (also known as a rim-rider or centerless wheel) is a type of wheel with no center hub. More specifically, the hub is actually almost as big as the wheel itself. The axle is hollow, following the wheel at very close tolerances.
A fixed-gear bicycle. An 18-tooth sprocket that attaches to the rear hub of fixed-gear bike. Track sprockets are typically attached and removed from the hub by screwing them with a chain whip. This tool incorporates a lockring spanner for securing a reverse threaded lockring against the sprocket. A fixed-gear bicycle (or fixed-wheel bicycle in ...
This is possible because of the location of the axles on the frame itself. One example is a Bauer frame that has two wheels in the front that are 76 mm (3.0 in) and two wheels in the back that are 80 mm (3.1 in). Another example is a 74–76–78–80 mm (2.9–3.0–3.1–3.1 in) wheel arrangement.
