Single-speed means there's only one gear to use. the rear Wheel will Always turn at a certain ratio WRT the pedals, usually about 1:3.
One pedal turn gives about 3 turns on the rear Wheel.
On bikes with more gears, you have different ratios to choose from. Headwind, or uphill, you can make pedalling easier. Tailwind or descents, you pick a faster gear and stay on Power instead of spinning out.
Rarest "krate" bike would be the Grey ghost,single speed. Under 300 ghosts made,much less for single speed.
A single gear, usually called a single-speed is a bike where the the rear wheel will always turn the same amount for one turn of the cranks. Means that the bike will be simple and rugged, but that the only way to climb a hill will be to push harder and the only way to get more speed is to pedal faster.
Pick a gear that gives you the right ratio, then go for it. No difference than from a single-speed bike.
A single speed bike will have less parts than a geared bike. With less parts it can be made lighter. With less parts there are fewer things that can break. Fewer parts makes for a cleaner look. The downside is that the bike won't be as adaptable for different riding conditions as a geared bike.
If by bike you mean bicycle then: Yes if you increase your speed or the intensity for that matter then your heart rate will also increase.
he ride a yellow bike that hasten speed
a 10 speed racer is a dirt bike a 10 speed racer is a dirt bike
If your looking to make a geared bike into a single speed you should get a SS converter kit, and have 1 chainring on the front

Really depends on what you mean by a "regular bike". But road bikes tend to be lighter, more slender and focused more on speed than everyday usefullness compared to a regular bike.
Yes, definitely size is a factor in selecting single speed bikes. These must be in accordance with your weight and height. Bike sizes vary from one user to the other. Don't ever buy a bike without trying it. In that way, you can be assured that it is the right bike for you. You test ride it and also see if the bike fits your body size and weight. Some people look too big on a small bike so you have to test it to see if it is appropriate for you. Buying without test riding these single speed bikes is the greatest mistake one can make in purchasing bikes. You may know what size fits you but different models have different size-fits so there is a need to try out before you commit to buying it.
Depends on what's on there now. If the bike has a multi-geared freewheel you simply have to pull that one off and install a single-speed(bmx) freewheel in its place. If the bike have a cassette hub you need to pull the cassette off, disassemble it and then reinstall one of the sprockets together with a stack of spacers and tighten up the lockring. Some special tools are required, and if your bike have vertical dropouts you'll still need to keep the rear derailer in order to keep the chain tensioned. IF you choose to buy an new, single-speed wheel instead, you need to make sure that the OLD(over-locknut-distance) matches the dropout width of the frame.
