Its a personal choice. I like direct, don't have to adjust or oil.
AnswerHere's a good write-up:Chain
In a vehicle, a driving gear is the gear which is driven by the engine. The driving gear helps control the speed the vehicle is in.
Belt drive is smoother and lasts much longer. Chain is better for very high torque and big swing arm movement applications, but replacement through chain stretch and sprocket wear a regular unwelcome expense
Direct 2 drive is not better than Gamestop. I suppose this may be a matter of personal opinion. But, both places have an excellent game selection and also offer old and new games.
If you have a bike with direct drive, like the old penny farthings and a kids tricycle, then the size of the drive wheel will seriously limit the speed you can get. But with a chain drive you can also introduce a gear ratio, allowing the drive wheel to spin faster than the pedals, making it possible to go faster.
It is chain drive.
A chain and sprockets.
Because if you have the pedals stuck to the wheel axle, and no gearing inbetween, the only way to get some useful speed out of the bike is to have a really large wheel.Because before the chain drive and gearing was invented, bikes were direct drive - meaning that the drive wheel spun at the same rate as the pedals. The only way to get some speed out of the bike then was to make the drive wheel really big.Once the chain drive made it easy to add a gearing ratio wheels could be built with equally sized wheels and a better rider position.
Chain drives are used to lift heavier, usually wooden, garage doors and work better in cold conditions.

I personally think belt drives are better than chain drives because belts won't squeak after a few years. I'm still looking for just a belt that I attach to my pedal so it'll be cheaper.
