So something interesting about me. I ride unicycle, a bike-like thing with only one wheel.

Unicycle
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 uncycling. 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 activities similar to mountain biking or trials. US patents for single-wheeled 'velocipedes' were published in 1869 by Frederick Myers and in 1881 by Battista Scuri.
Unicycle trials
Unicycle trials is a form of unicycling which involves participants attempting to ride a unicycle over obstacles without any part of the rider touching the ground. The obstacles traversed can be set up specifically for the purpose of unicycle trials, but are often walls, railings, ledges and other "street furniture" found in an urban environment. The sport is derived from (or at least inspired by) bike trials and motorcycle trials. Obstacles are traversed using various moves. Hopping is achieved by suddenly forcing the unicycle pedals downwards while holding the seat, the reactive forces resulting from the compression of the tyre lift the unicycle into the air.
Suspension (vehicle)
Suspension is the system of tires, tire air, springs, shock absorbers and linkages that connects a vehicle to its wheels and allows relative motion between the two. Suspension systems must support both roadholding/handling and ride quality, which are at odds with each other. The tuning of suspensions involves finding the right compromise. It is important for the suspension to keep the road wheel in contact with the road surface as much as possible, because all the road or ground forces acting on the vehicle do so through the contact patches of the tires. The suspension also protects the vehicle itself and any cargo or luggage from damage and wear.
Bicycle and motorcycle dynamics
Bicycle and motorcycle dynamics is the science of the motion of bicycles and motorcycles and their components, due to the forces acting on them. Dynamics falls under a branch of physics known as classical mechanics. Bike motions of interest include balancing, steering, braking, accelerating, suspension activation, and vibration. The study of these motions began in the late 19th century and continues today. Bicycles and motorcycles are both single-track vehicles and so their motions have many fundamental attributes in common and are fundamentally different from and more difficult to study than other wheeled vehicles such as dicycles, tricycles, and quadracycles.
Electric bicycle laws
Many countries have enacted electric bicycle laws to regulate the use of electric bicycles. Countries such as the United States and Canada have federal regulations governing the safety requirements and standards of manufacture. Other countries like the signatories of the European Union have agreed to wider-ranging legislation covering use and safety of their term EPAC (electric pedal-assisted cycles). However, confusion remains regarding the various laws involving electric bicycles. This stems from the fact that while some countries have national regulations, the legality of road use is left to states and provinces, and then complicated further by municipal laws and restrictions.
Nik Wallenda
Nikolas "Nik" Wallenda (born January 24, 1979) is an American acrobat, aerialist, daredevil, high wire artist, and author. He is known for his high-wire performances without a safety net. He holds nine Guinness World Records for various acrobatic feats, but is best known as the first person to walk a tightrope stretched directly over Niagara Falls. A seventh-generation member of The Flying Wallendas family, Nik Wallenda participated in various circus acts as a child. At age 13, he made his professional tightrope walking debut. He chose high-wire walking as his career in 1998, after joining family members in a seven-person pyramid on the wire.
Owu Kingdom
The ethnic people of Owu (Owus) are part of the Yoruba people of West Africa. Ago-Owu in Abeokuta is where the Owus are mostly concentrated, however large Owu settlements are found throughout the Yoruba kingdom. The Yoruba kingdom extends beyond the boundaries of Nigeria into the Republic of Benin. The history of the Owus was first documented following their first settlement in Ago-Owu in 1820. It is believed from oral history tradition that the Owus occupied an area directly along and below Niger River in the present country of Nigeria. The southward migration of the Owus was a direct result of both tribal and ethnic conflicts.
