SAND BOARDING

Sandboarding is a board sport similar to snowboarding. It is a recreational activity that takes place on sand dunes rather than snow-covered mountains. This boardsport has adherents throughout the world, most prevalently in desert areas or coastal areas with beach dunes.
It involves riding across or down a dune while standing with both feet strapped to a board, though some sandboarders use a board without bindings.
It is less popular than snowboarding, partly because it is very difficult to build a mechanised ski lift on a sand dune, and so participants generally must walk back up to the top. Alternatively, they may ride a dune buggy or all-terrain vehicle back to the top of the dune. Dunes are normally available year-round as opposed to ski resorts, which are usually seasonal. As well, the availability of sand dunes confines participants to warmer areas.
Josh Tenge, professional sandboarding champion, holds the Guinness Book of World Records entry for the longest-distance back flip at 44' 10". Tenge is also a four-time world sandboarding champion and holds three world records.
Namibia is the centre of sand-skiing, which is similar to sandboarding; however, it is performed with skis instead of a board.

FIXED GEAR

The oldest and simplest type of bicycle is the "fixed-gear" bicycle. This is a single-speed bike without a freewheel: that is, whenever the bike is in motion, the pedals will go around. You cannot coast on a fixed-gear machine.

 It is worth going through this learning experience, however, because once you do so, you will discover a new joy in cycling. When you ride a fixed gear, you feel a closer communion with your bike and with the road. There is a purity and simplicity to the fixed-gear bicycle that can be quite seductive. Somehow, once you get past the unfamiliarity, it is just more fun than riding a bike with gears and a freewheel!

Fixie bikes are probably best known for their uniqueness and variety. You will see fixed gear bikes in the city with drop handlebars, but you will also see fixies with flat handlebars and with or without brakes


Long, long gone are the times when biking meant bulky bicycles with tons of accessories. As these vehicles get more integrated to everyday lives, people are looking for simple models that just get the job done. Additionally, we live in times when frugal living and simpleness have become desirable values for some segments.
So the simple and clean look of fixies fits right in in these two aspirations. They're as clean as it gets for bikes, with just light frames, no gears and thin tires.You can surely modify and customize almost any bike, but there is a whole culture of customizing fixed gear bikes that has surely added to the growth of the trend. It is the reason why fixed gear now become an trend in a teenagers life.

Riding a fixed gear on the road is excellent exercise. When you need to climb, you don't need to think about when to change gears, because you don't have that option. Instead, you know that you must just stand up and pedal, even though the gear is too high for maximum climbing efficiency. This makes you stronger.
If you have the option of gearing down and taking a hill at a slow pace, it is easy to yield to the temptation. When you ride a fixed gear, the need to push hard to get up the hills forces you to ride at a higher intensity than you otherwise might. Really steep hills may make you get off and walk, but the hills you are able to climb, you will climb substantially faster than you would on a geared bicycle.
