A bicycle, also called a bike or cycle, is a human-powered or motor-powered, pedal-driven, single-track vehicle, having two wheels attached to a frame, one behind the other. A bicycle rider is called a cyclist, or bicyclist.
A mountain bike (MTB) or mountain bicycle is a bicycle designed for off-road cycling. Mountain bikes share some similarities with other bicycles, but incorporate features designed to enhance durability and performance in rough terrain, which makes them heavy. These typically include a suspension fork, large knobby tires, more durable wheels, more powerful brakes, straight, extra wide handlebars to improve balance and comfort over rough terrain, lower gear-ratios for climbing steep grades and sometimes rear suspension to really smooth out the trail as well as dropper-posts to quickly adjust the seat height.
Xootr is a manufacturer of folding kick scooters and was formerly a seller of folding bicycles. Xootr scooters are characterized by 180 mm wheels with aluminium hubs, and a hand brake for the front wheel. Compared to the other folding scooters with smaller wheels, these larger wheels provide an easier ride, at the expense of a somewhat less easy portability. The hinge is distinguished from competitors in being locked by inserting a pin, rather than by a cam or other latch. The platform is large enough for adults, and available in plywood, magnesium, or aluminum at different prices.
A bicycle frame is the main component of a bicycle, onto which wheels and other components are fitted. The modern and most common frame design for an upright bicycle is based on the safety bicycle, and consists of two triangles: a main triangle and a paired rear triangle. This is known as the diamond frame. Frames are required to be strong, stiff and light, which they do by combining different materials and shapes.
A bicycle wheel is a wheel, most commonly a wire wheel, designed for a bicycle. A pair is often called a wheelset, especially in the context of ready built "off the shelf" performance-oriented wheels.
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.
A utility bicycle,city bicycle, urban bicycle, European City Bike (ECB), classic bike or simply city-bike, is a bicycle designed for frequent short, moderately paced rides through relatively flat urban areas. It is a form of utility bicycle commonly seen around the world, built to facilitate everyday riding in normal clothes in a variety of weather conditions. It is therefore a bicycle designed for practical transportation, as opposed to those primarily for recreation and competition, such as touring bicycles, racing bicycles, and mountain bicycles. Utility bicycles are the most common form globally, and comprise the vast majority found in the developing world. City bikes may be individually owned or operated as part of a public bike sharing scheme.
A racing bicycle, also known as a road bike, and once popularly known as a ten speed, is a bicycle designed for competitive road cycling, a sport governed by and according to the rules of the Union Cycliste Internationale (UCI). The UCI rules were altered in 1934 to exclude recumbent bicycles.
A bicycle fork is the part of a bicycle that holds the front wheel.

A fork end, fork-end, or forkend is a slot in a bicycle frame or bicycle fork where the axle of a bicycle wheel is attached. A dropout is a type of fork end that allows the rear wheel to be removed without first derailing the chain.
Brompton Bicycle is a British manufacturer of folding bicycles based in Greenford, London.
Dirt jumping is the practice of riding bikes over jumps made of dirt or soil and becoming airborne. Dirt Jumping evolved alongside BMX racing and is similar to BMX or Mountain bike racing in that the rider jumps off of mounds of dirt, usually performing a midair trick in between. It differs in that the jumps are usually much larger and designed to lift the rider higher into the air. Additionally, the goal is not to complete the course with the fastest time, but rather to perform the tricks with the style. Dirt jumping can be performed on BMX bikes or specialized mountain bikes known simply as "dirt jumpers".
Bicycle suspension is the system, or systems, used to suspend the rider and bicycle in order to insulate them from the roughness of the terrain. Bicycle suspension is used primarily on mountain bikes, but is also common on hybrid bicycles.
The tikit is a 16-inch wheel folding bicycle with an unusually fast folding mechanism that can be folded/unfolded in less than five seconds. The tikit was manufactured in the United States by Bike Friday from 2007 to 2016
