A bicycle, also called a cycle or bike, 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.
Longboarding is riding on a longboard. Longboards vary in shape and size. Compared to skateboards, longboards are more stable, and have more traction and durability due to larger wheel size and lower wheel durometers. Many longboards use trucks (axles) that have different geometric parameters than skateboards. There are a variety of longboard disciplines, and types of longboards. Longboarding has competitive races down hill where riders can reach speeds exceeding 60 mph (97 km/h). The wider turning radius of longboards can turn, as well as their ability to coast long distances make them more suitable for cruising and commuting on streets than regular skateboards.
In mechanical or automotive engineering, a freewheel or overrunning clutch is a device in a transmission that disengages the driveshaft from the driven shaft when the driven shaft rotates faster than the driveshaft. An overdrive is sometimes mistakenly called a freewheel, but is otherwise unrelated.
Mountainboarding, also known as Dirtboarding, Offroad Boarding, and All-Terrain Boarding (ATB), is a well established if little-known action sport, derived from snowboarding. This was initially pioneered by James Stanley during a visit in the 1900s to the Matterhorn where snow was not available. A mountainboard is made up of components including a deck, bindings to secure the rider to the deck, four wheels with pneumatic tires, and two steering mechanisms known as trucks. Mountainboarders, also known as riders, ride specifically designed boardercross tracks, slopestyle parks, grass hills, woodlands, gravel tracks, streets, skateparks, ski resorts, BMX courses and mountain bike trails. It is this ability to ride such a variety of terrain that makes mountainboarding different from other board sports.
Street luge is an extreme gravity-powered activity that involves riding a street luge board down a paved road or course. Street luge is also known as land luge or road luge. Like skateboarding, street luge is often done for sport and for recreation.
Vehicle braking system fade, or brake fade, is the reduction in stopping power that can occur after repeated or sustained application of the brakes, especially in high load or high speed conditions. Brake fade can be a factor in any vehicle that utilizes a friction braking system including automobiles, trucks, motorcycles, airplanes, and bicycles.
A kick scooter is a human-powered street vehicle with a handlebar, deck, and wheels propelled by a rider pushing off the ground. Today, the most common scooters are made of aluminum, titanium, and steel. Some kick scooters made for younger children have 3 to 4 wheels and are made of plastic or don't fold. High-performance racing scooters made for adults resemble the old "penny-farthing".
In road vehicles, the parking brake, also known as a hand brake or emergency brake (e-brake), is a mechanism used to keep the vehicle securely motionless when parked. Historically, it was also used to help perform an emergency stop should the main hydraulic brakes fail. Parking brakes often consist of a cable connected to two wheel brakes, which is then connected to a pulling mechanism. In most vehicles, the parking brake operates only on the rear wheels, which have reduced traction while braking. The mechanism may be a hand-operated lever, a straight pull handle located near the steering column or a foot-operated pedal located with the other pedals.
Ford Model AA is a truck from Ford. As the Model T and TT became obsolete and needed to be replaced, Henry Ford began initial designs on the Model A and Model AA in 1926. Basic chassis layout was done rapidly and mechanical development was moved forward quickly. Body design and style was developed and then outsourced to various body manufacturers, including Briggs and Murray. The designs of the Model A shared parts and materials with the Model AA Ford, notably the body, engine and interior. The AA usually received plainer interiors than their car counterparts. The Model AA followed similar design changes to the Model A during the AA's four years in production, often delayed anywhere from three to nine months. The mechanical changes and upgrades were done during production of the vehicles. Body changes that occurred between 1929 and 1930 were also integrated into AA production, but leftover parts were used longer in the heavy commercial trucks.
A slide is a skateboarding trick where the skateboarder slides sideways either on the deck or on the wheels.
A fingerboard is a working replica of a skateboard that a person "rides" by replicating skateboarding maneuvers with their fingers. The device itself is a scaled-down skateboard complete with graphics, trucks and moving wheels. A fingerboard is commonly about 100 millimeters (3.9 in) long, and can have a variety of widths ranging from 26 to 34 mm. Skateboarding tricks may be performed using fingers instead of feet. Tricks done on a fingerboard are inspired by tricks done on real skateboards. Professional skateboarder Lance Mountain is widely credited as making the first fingerboard, and his skit in Powell-Peralta's "Future Primitive" video brought fingerboarding to the skateboarders of the world in the mid-1980s. Around the same time, he wrote an article on how to make fingerboards in TransWorld SKATEboarding magazine.
Slalom skateboarding is a form of downhill skateboard racing that first appeared in the 1960s and 1970s and has made a resurgence in popularity in the 2000s. Slalom racers skate down a course usually marked by plastic cones. The racer tries to get through the course with the fastest time, while knocking down the fewest cones. Each cone typically carries a penalty of a fraction of a second which is added to the skater's time.
A freeboard is a specialist skateboard designed to closely simulate the behaviour of a snowboard. Freeboards were developed to allow snowboarders to transition to skateboarding without the need to adapt to a smaller deck and narrower wheel-base.
An electric skateboard is a personal transporter based on a skateboard. The speed is controlled by a hand-held throttle or weight-shifting and the direction of travel is adjusted by tilting the board to one side or the other.
Street skateboarding is a skateboarding discipline which focuses on flat land tricks, grinds, slides and aerials within urban environments and public spaces. Street skateboarders meet, skate and hang out, in and around urban areas referred to as "spots", which are commonly streets, plazas or industrial areas. To add variety and complexity to street skateboarding; obstacles such as handrails, stairs, walls, flower beds, bins, park benches, picnic tables and other street furniture may be traversed as part of a single trick or a series of consecutive tricks called a line.
A Penny board is a type of plastic skateboard, known within the industry as a short cruiser. The term "Penny" is synonymous with "Penny Skateboards", an Australian-based company founded in 2010 by Ben Mackay. Penny is a registered trademark for skateboards, but has been widely genericised to describe all small plastic skateboards due to the brand's popularity. Penny Skateboards pair a plastic deck with cruiser wheels and trucks. This combination now epitomises a "Penny board" in generic terms. Because they are made out of plastic, Penny boards have a lighter weight, but are also strong.
Boosted is an American manufacturer of electric skateboards and electric scooters based in Mountain View, California.
