Racing bikes are so different from your conventional bike in many ways. They are made to be a lot lighter than the average bike you see today and are made for speed. Racing bikes are fitted with minimum components the gears can range from 18 gears to 30 gears.
That's a pretty muddled question, you might as well ask what makes shoes different from other shoes. BMX bikes can be built for different uses, there are race bikes that are light and have brakes, there are vert/trick bikes that don't have brakes and can take a lot of abuse.
Apollo Bicycles makes Apollo bikes. They are an Australian-based bike manufacturer. They provide different kinds of bikes, bike parts, and equipment.
Fox Racing sells a number of different products other than shoes. These include different types of clothing suitable for bike racing as well as sunglasses.
In racing bikes, ideally as much as possible is carbon because it's light. However, generally moving parts are made of other materials as carbon is not great for that kind of thing.
Colnago bikes can be purchased from a range of different places. The site to be used will depend on the exact Colnago bike that the customer requires. The store Evans Cycles stocks some of this brand of bike.
Profile Racing is about as high end as you can get. They've been around longer than any other BMX frame manufacturer and have made BMX frames and cranksets for many other companies over the years (GT, Hutch, etc.)
I have a Sportster 1200 Custom. The thing that makes the Sportster different is it's top heavy compared to the other bikes I've ridden. As long as you are aware of that. It's easy to ride.
yes he used some different parts
The BMX bikes that you buy at Target and or Walmart are not the same BMX bikes that are used in BMX Racing and BMX Freestyle. Real BMX bikes are lighter, they have diiferent size sprockets among many other things. Feel free to google the National Bicycle League or the American Bicycle League to get more information.
they are different to each other
what makes the heart different to the other organs
With cars, bikes, skateboards or just whatever the individual prefers. It's no different than other countries.
