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.
Single speed bikes are generally safe, but one does need to be aware of a few tips. Since the resistance of the chain cannot be adjusted, it is easier to lose control of the bike. Also, it may be harder to slow down when one wants to stop the bike.
You need a chain meant for single-speed or internally geared bikes, cut to the right length.
Your question doesn't really make sense, as geared bikes also have pedals.Basically there's a difference between single-speed bikes(like BMXes) and road bikes/MTBs.On a single-speed bike the rear wheel will turn at the same rate when compared to the pedals all the time.If you want to ride uphill, you have to push harder, and the faster you go, the faster you have to spin the pedals.On a geared bike it's possible to change the gear ratiobetween the pedals and the rear wheel. This means that you can trade power for speed , or the other way around.If going uphill is heavy, you just drop down a gear. It'll lose you some speed, but it'll make you stronger at the same time so that you'll be able to climb the hill.
Single speed bicycles have some advantages over multi-speed bikes. For the same build quality, a single speed bicycle can be cheaper and lighter. They require less maintenance and have fewer parts that can break or fail.

e-bikes max speed 50 cc !" no need license :)
Another muddy question. Rims on a bike can be either single-walled or double-walled, with double-walls being the stronger choice. Never heard of triple walled. Cranks OTOH can have either a single chainwheel, double chainwheels or triple chainwheels. Singles are most common for bikes that are single-speed, have internal gears, or sports bikes built for a specific purpose, like BMX, dirt or track bikes. Double chainwheels are pretty much the standard for road bikes, while MTBs, hybrids and touring bikes often have triples to widen the range of available gears.
Roketa Bikes do not have speed limiters in their systems. In order to go faster, you need to change gears while in final drive.
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.
There are several different bicycle speed records, there are UCI-approved bikes, there are recumbents with fairings, there are bikes that have to be towed to speed and then are ridden in the wake behind the towing vehicle, there are bikes that are pedalled from standstill, in the wake of a precursor vehicle. Then there are the Downhill bikes. Speaking about ONE record for all the variations of bike is rather pointless.
No way of telling, it depends on what you want from it. Single-speeds require less maintenance and can be good for cadence training, but they're inherently less efficient as travelling machines than geared bikes.
Hp in a bikes means Horse power, which in automobile science they used to described the speed generated by the auto
old school bikes had 3 or 4 speed, then they got five speeds later,but todays bikes can have 5 or 6 speed now.
