A bicycle pedal is the part of a bicycle that the rider places their feet on when cycling. It provides the connection between the cyclist's foot or shoe and the crankarm allowing the leg to turn the crank. Pedals usually consist of a spindle that threads into the end of the crankarm and a body, on which the foot rests or is attached, that is free to rotate on bearings with respect to the spindle.

The Velocipede, a predecessor to the bicycle, lacked pedals but allowed the crank to be operated by means of a treadle. Pedals were initially attached to crankarms connecting directly to the driven (usually front) wheel. The safety bicycle as we know it today came into being when the pedals were attached to a crankarm driving a ring gear that transmitted power to the driven wheel by means of a chain. The velocipede was the predecessor of the bicycle, a human-powered vehicle introduced in the Victorian age. ...

Flat & Platform
Traditionally, platform pedals were pedals with a relatively large flat area for the foot to rest on, in contrast to the quill pedal which had very little surface area. Image File history File linksMetadata Download high resolution version (1600x1200, 206 KB)I took this photo on 8-15-2005. ...

One form of the platform pedal had a large flat top area and flat bottom for use with toe clips and toe straps, and were designed for greater comfort when using shoes with less than rigid soles. They typically had a smaller cutaway underside giving greater cornering clearance, which was often needed on the track. They were often marketed as being more aerodynamic that conventional quill pedals.
In mountain biking and BMX, platform pedals typically refer to any flat pedal without a cage. MTB and BMX riders alike prefer platforms to cage pedals because they offer more grip using short metal studs, are rounder and do less damage to a rider's shins and ankles during an accident. Cage pedals will often scrape skin and flesh off the shin if the rider stops short and loses footing of the pedal. Mountain biker riding in the Arizona desert. ...

Platform pedals are available in a wide variety of types and price ranges, ranging from disposeable plastic units used for test rides on new bicycles to high-end downhill models. Budget models may be made of steel or aluminum and incorporate reflectors for safer riding on streets at night. Less expensive platform pedals are generally considered disposeable and cannot be rebuilt when worn out.
More expensive platform pedals for the mountain bike market are available with replaceable metal traction pins and cartridge bearings. In recent years lightweight pedals intended for Freeride and downhill cycling have been made from exotic alloys such as magnesium.

Toe clips typically aren't installed on this type of pedal because they are considered unsafe by some MTB and BMX riders.
Quill pedals Very early pedals were simply platforms (with a rotating axis) on which the cyclist could press downward with the foot. Then cages called toe clips were added to help keep the foot in place. Image File history File links No higher resolution available. ...

Cages now refer to pedals that can accommodate toe clips and not necessarily the clips themselves, they are more specifically called quill pedals. The actual cage is the outer part of a conventional pedal, the part that comes into contact with the rider's shoe and has holes where toe clips can be secured by screws. Toe straps used with clips further secure the foot to the pedal and to allow the cyclist to apply power on the upstroke by pulling against the pedal. Traditionally toe straps could be used with toe clips in conjunction with slotted cycling shoes. The clip is generally made of metal or high impact plastic. The strap is generally made of leather or nylon.
The main difference between track, road, and touring quill pedals is width. Track pedals are narrow and the front and back plates of the cage are separate, road being a little wider with a one piece cage in a shape of a sideways "U", and touring being the widest to allow for comfort when used with wider, non-racing shoes during longer rides.
 Bicycle pedal (left), quill road type, with toe clip and toe strap. Early 1980s. While quill pedals can be used for mountain biking, they are not ideal since use of clips for MTB is dangerous and they do not offer substantial grip. Cage pedals built for mountain biking are typically serrated so that even when muddied, the pedals can be gripped well by any flat shoe.

 Cycling shoe with a slotted shoeplate attached to its sole Although quill pedals can be used with smoothed-soled cycling shoes or ordinary shoes, they were designed to be used with cycling shoes which had a slotted shoeplate attached to its sole. The slot in the shoeplate fits into the rear plate of the pedal, and together with the toe strap and to a lesser extent the toeclip, the shoe is held firmly to the pedal. The disadvantage with this system is that to remove the shoe from the pedal a rider had to reach down and loosen the toestrap by hand--or, more commonly with casual riders, leave the toe strap loose and thus give up some efficiency. This type of pedal and shoe were used by all racing cyclists until the mid to late 1980s. Image File history File linksMetadata No higher resolution available. ...

Generally pedals that could be used with toe clips had a "pick up" tab on the rear of the pedal. The weight of the toe clip and strap would make the pedal hang upside down, and the rider would tap the tab with their shoe to flip the pedal over so the shoe could be inserted into the pedal.
Clipless pedals
 SPD Dual Choice with shoe Clipless pedals (also clip-in or step-in) require a special cycling shoe with a cleat fitted to the sole, which locks into a mechanism in the pedal holding the shoe firmly to the pedal. Clipless refers to not using an external toe clip.

The clipless pedal was invented by Charles Hanson in 1895. It allowed the rider to twist the shoe to lock and unlock, and had rotational float. [1]
The M71 was a clipless pedal designed by Cino Cinelli and produced by his company in 1971. It used a plastic shoe cleat which slid into grooves in the pedal and locked in place with a small lever located on the back side of the pedal body. To release the shoe a rider had to reach down and operate the lever, similar to the way a racing cyclist had to reach down and loosen the toestrap. The lever was placed on the outside edge of the pedal so that in the event of a fall the lever hitting the ground would release the foot. The pedal was designed for racing, in particular track racing. Cinelli is an Italian bicycle manufacturing company based in Milan, Italy, producing mostly road bicycles and components; production is estimated at 80% components, 20% bicycles. ...

In 1984, the French company LOOK applied downhill snow skiing binding or cleat technology to pedals producing the first widely used clipless pedals. Bernard Hinault's victory in Tour de France in 1985 helped secure the acceptance of quick-release clipless pedal systems by cyclists. Those pedals, and compatible models by other manufacturers, remain in widespread use today. The cleat is engaged by simply pushing down and forward on the pedal, or, with some designs, by twisting the cleat in sideways. Then, instead of loosening a toestrap or pulling a lever, the cyclist releases a foot from the pedal by twisting the heel outward. First time clipless users may forget to unclip when coming to a stop, sometimes resulting in a low speed fall.

The next major development in clipless pedals was Shimano's SPD (Shimano Pedaling Dynamics) pedal system. Whereas Look cleats are large and protrude from the sole of the shoe, SPD cleats are small and could be fitted in a recess in the sole, making it possible for walking, although comfortability will vary, as the soles of different cycling shoes vary in their rigidity depending on design. 1984 The first clipless pedal is invented. ...
Cycling shoes have stiff or rigid soles to maximize power transfer and efficiency. They may be specific to road or mountain biking, or usable for both. Shoes designed for mountain biking typically have recessed cleats that do not protrude beyond the sole of the shoe, and have treads for walking on trails, as walking the bike is frequently needed. Road cycling shoes are designed only for cycling and not for walking. They normally have a protruding cleat – which makes them awkward to walk in and prone to damage – and a completely rigid sole.
Mountain bike cleats can generally be mounted without difficulty to road shoes although sometimes an adapter is required. The inverse is not normally true as the cleats used with road pedals are normally too large. The smaller mountain bike cleats are attached to the sole of the shoe by two bolts; larger road-specific cleats are attached by three.
Various other manufacturers have produced their own design of clipless pedal systems over the years, most notably BeBop, LOOK, Speedplay, Time, and Shimano. LOOK, established at Nevers, France in 1951, was originally a ski equipment manufacturer. ...

Attachment to crank arm The pedal spindle is threaded to match a threaded hole at the outboard end of the crank arms. Adult or multi-piece cranks have a 9/16 inch hole with 20 TPI (a diameter/pitch combination fairly unique to this application). One-piece or kids cranks use a 1/2 inch hole. Screw thread, used to convert torque into the linear force in the flood gate. ...
The right-side (usually the drive-side) pedal spindle is right-hand threaded, and the left-side (usually the non-drive-side) pedal spindle is left-hand (reverse) threaded to help prevent it from becoming loose by an effect called precession. Precession of a gyroscope Precession refers to a change in the direction of the axis of a rotating object. ...
Although the left pedal turns clockwise on its bearing relative to the crank arm (and so would seem to tighten a right-hand thread), the force from the rider's foot presses the spindle against the crank arm thread at a point which rolls around clockwise with respect to the crank arm, thus slowly pulling the outside of the pedal spindle anticlockwise (counterclockwise) because of friction and thus would loosen a right-hand thread. A clockwise motion is one that proceeds like the clocks hands: from the top to the right, then down and then to the left, and back to the top. ...
