A clown bicycle or clown bike is a bicycle designed for comedic visual effect or stunt riding, typically by circus clowns. It is sometimes called a circus bike.
Some clown bikes are also fixed gear, with no freewheeling, so that they may be pedaled either forward or backwards. Some are built very small but are otherwise relatively normal. Pedaling an extremely small bicycle is very difficult and usually much slower than walking, so there is little practical advantage to having a bicycle that will fit in one's purse or pocket.

A bicycle, also called a pedal cycle, bike, push-bike or cycle, is a human-powered or motor-assisted, pedal-driven, single-track vehicle, with two wheels attached to a frame, one behind the other. A bicycle rider is called a cyclist, or bicyclist.
A unicycle is a vehicle that touches the ground with only one wheel. The most common variation has a frame with a saddle, and has a pedal-driven direct-drive. A two speed hub is commercially available for faster unicycling. Unicycling is practiced professionally in circuses, by street performers, in festivals, and as a hobby. Unicycles have also been used to create new sports such as unicycle hockey. In recent years, unicycles have also been used in mountain unicycling, an activity similar to mountain biking or trials.
A tandem bicycle or twin is a form of bicycle designed to be ridden by more than one person. The term tandem refers to the seating arrangement, not the number of riders. Patents related to tandem bicycles date from the mid 1880s. Tandems can reach higher speeds than the same riders on single bicycles, and tandem bicycle racing exists. As with bicycles for single riders, there are many variations that have been developed over the years.
A tricycle, sometimes abbreviated to trike, is a human-powered three-wheeled vehicle.
A bicycle brake reduces the speed of a bicycle or prevents the wheels from moving. The two main types are: rim brakes and disc brakes. Drum brakes are less common on bicycles.
The penny-farthing, also known as a high wheel, high wheeler or ordinary, is an early type of bicycle. It was popular in the 1870s and 1880s, with its large front wheel providing high speeds, owing to it travelling a large distance for every rotation of the legs, and comfort, because the large wheel provided greater shock absorption.
A touring bicycle is a bicycle designed or modified to handle bicycle touring. To make the bikes sufficiently robust, comfortable and capable of carrying heavy loads, special features may include a long wheelbase, frame materials that favor flexibility over rigidity, heavy duty wheels, and multiple mounting points.
Indoor cycling, often called spinning, is a form of exercise with classes focusing on endurance, strength, intervals, high intensity and recovery, and involves using a special stationary exercise bicycle with a weighted flywheel in a classroom setting. When people took cycling indoors in the late 19th century, whether for reasons of weather or convenience, technology created faster, more compact and efficient machines over time. The first iterations of the stationary bike ranged from the vertical Gymnasticon to regular bicycles on rollers.
A racing bicycle, also known as a road bike is a bicycle designed for competitive road cycling, a sport governed by and according to the rules of the Union Cycliste Internationale (UCI).
A cyclo-cross bike or cyclo-cross bicycle is a bicycle specifically designed for the rigors of a cyclo-cross race. Cyclo-cross bicycles roughly resemble the racing bicycles used in road racing. The major differences between the two are the frame geometry, and the wider clearances that cyclo-cross bikes have for their larger tires and mud and other debris that they accumulate.
A fixed-gear bicycle is a bicycle that has a drivetrain with no freewheel mechanism such that the pedals always will spin together with the rear wheel. The freewheel was developed early in the history of bicycle design but the fixed-gear bicycle remained the standard track racing design. More recently the "fixie" has become a popular alternative among mainly urban cyclists, offering the advantage of simplicity compared with the standard multi-geared bicycle.
A tall bike is an unusually tall bicycle often constructed by hobbyists from spare parts. Typically, two conventional bicycle frames are connected, by welding, brazing, or other means, one atop the other. The drive train is reconfigured to connect to the upper set of pedals, and the controls are moved to the upper handlebar area.
The bunny hop (mountain biking) or bunnyhop, also known as the J-Hop, is a bicycle trick that allows the rider to launch their bike into the air as if jumping off a ramp. The pedals on the bicycle stick to the riders feet as the bike becomes airborne with the clipless pedals that have clips. The pedals on the bicycle seem to stick to the rider's feet as the bike becomes airborne, much like how a skateboard seems to stick to the feet of the skater performing an ollie. While the bunny hop can be quite challenging to learn, once mastered it gives riding opportunities for both BMX and mountain bike rider alike.
A bicycle handlebar is the steering control for bicycles. It is the equivalent of a tiller for vehicles and vessels, as it is most often directly mechanically linked to a pivoting front wheel via a stem which in turn attaches it to the fork. Besides steering, handlebars also often support a portion of the rider's weight, depending on their riding position, and provide a convenient mounting place for brake levers, shift levers, cyclocomputers, bells, etc.
A rowing cycle is a wheeled vehicle propelled by a rowing motion of the body. Steering, braking, and shifting are usually done by the handlebars. Feet are on symmetrical foot rests, as opposed to rotating pedals. Unlike many rowing boats, the rider faces forward. Rowing cycles exist in numerous designs, particularly with respect to frames and drive mechanisms. Commercial production numbers for rowing cycles are small compared to that of standard bicycles.
Small-wheel bicycles are adult bicycles that have wheels of 510 mm (20 in) nominal diameter or less, which is smaller than the 700c (522 mm), 660, 700, 740 mm (26, 27.5, 29 in) sizes common on most full-sized adult bikes. While many folding bicycles are small-wheel bicycles, not all small-wheel bicycles can fold. Some small-wheel bicycles neither fold nor separate, such as the Moulton, which comes in both fixed-frame and separable-frame versions. While BMX bikes also have 510 mm (20 in) wheels, they are not normally categorised as "small-wheel bikes".
The following outline is provided as an overview of and topical guide to bicycles:
A wheelie bike, also called a dragster, muscle bike, high-riser, spyder bike or banana bike, is a type of stylized children's bicycle designed in the 1960s to resemble a chopper motorcycle and characterized by ape hanger handlebars, a banana seat with sissy bar, and small wheels. Notable examples include the Schwinn Sting-Ray and Krate lines and the Raleigh Chopper line. Other notable manufacturers and retailers that offered models include AMF, CCM, Columbia, Huffy, Iverson, J. C. Penney, Malvern Star, Monark, Murray, Ross, Sears, and Vindec.
